CL-1 SAFETY CONSIDERATIONS Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that apply. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing operations. Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than 1/ psig, it must be replaced before use. When 2 pressure testing field-supplied gas piping at pressures of 1/2 psig or less, a unit connected to such piping must be isolated by manually closing the gas valve. Before performing service or maintenance operations on unit, turn off main power switch to unit and install lockout tag. Electrical shock could cause personal injury. INSTALLATION Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation side down. Seals around duct openings must be tight. See Fig. 1. Step 1 — Provide Unit Support ROOF CURB — Assemble and install accessory roof curb in accordance with instructions shipped with curb. See Fig. 2. Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb, not to the unit. The accessory thru-the-bottom power and gas connection package must be installed before the unit is set on the roof curb. If fieldinstalled (thru-the-roof curb) gas connections are desired, use factory-supplied 3/4 in. pipe coupling and gas plate assembly to mount the thru-the-roof curb connection to the roof curb. Gas connections and power connections to the unit must be field installed after the unit is installed on the roof curb. If electric and control wiring is to be routed through the basepan, attach the accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions. IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 2. Improperly applied gasket can also result in air or water leaks and poor unit performance. Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. PC 111 Catalog No. 534-774 Printed in U.S.A. Form 48TJ-18SI Pg 1 10-00 Replaces: 48TJ-16SI Book 1 4 Tab 1a 6a Fig. 1 — Horizontal Conversion Panels (Viewed from Duct End) Step 3 — Install External Trap for Condensate Drain — The unit’s 3/4-in. condensate drain connections are Curb should be level. Unit leveling tolerances are shown in Fig. 3. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required. SLAB MOUNT (Horizontal Units Only) — Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a gravel apron in front of condenser coil air inlet to prevent grass and foliage from obstructing airflow. NOTE: Horizontal units may be installed on a roof curb if required. located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with vertical or horizontal applications. When using the standard side drain connection, make sure the plug (Red) in the alternate bottom connection is tight before installing the unit. To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. See Fig. 4. The piping for the condensate drain and external trap can be completed after the unit is in place. All units must have an external trap for condensate drainage. Install a trap at least 4-in. deep and protect against freezeup. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit connection (3/4 in.). Step 2 — Field Fabricate Ductwork — Secure all ducts to roof curb and building structure on vertical units. Do not connect ductwork to unit. For horizontal applications, fieldsupplied flanges should be attached to horizontal discharge openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes. Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier. If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes. A minimum clearance is not required around ductwork. Cabinet return air static shall not exceed –.30 in. wg with EconoMi$er, or –.35 in. wg with Durablade Economizer, or –.45 in. wg without economizer. These units are designed for a minimum continuous returnair temperature of 50 F (dry bulb), or an intermittent operation down to 45 F (dry bulb) (in heating mode), such as when used with a night set-back thermostat. Step 4 — Rig and Place Unit — Inspect unit for transportation damage. File any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1 and Fig. 5 for additional information. Lifting holes are provided in base rails as shown in Fig. 6. Refer to rigging instructions on unit. All panels must be in place when rigging and lifting. 2 ‘‘B’’ 1′-911/16″ [551] ‘‘C’’ 1′-4″ [406] ‘‘D’’ ALT DRAIN HOLE 13/4″ [44.5] ‘‘E’’ Gas “F” “G” Power Control 3/ ″ 4 3/ ″ [19] NPT 4 1 [19] NPT 1 /4″ 1/ ″ [31.7] 2 1/ ″ 3/ ″ [12.7] NPT 2 4 [12.7] NPT [19] NPT 3/ ″ 11/4″ 4 [19] NPT [31.7] CONNECTOR PKG ACY ROOF CURB ACCESSORY CRBTMPWR001A00 CRRFCURB001A00 CRBTMPWR002A00 CRRFCURB002A00 CRBTMPWR003A00 CRBTMPWR004A00 ‘‘A’’ UNIT SIZE 48TJ 1′-2″ [356] 2′-0″ [610] 004-007 NOTES: 1.

TO ENSURE AIRTIGHT CONNECTION PLACE UNIT AS CLOSE TO END AS POSSIBLE. Fig. 2 — Roof Curb Dimensions 3 Be sure that unit is installed so that snow will not block the combustion intake or flue outlet. Unit may be installed directly on wood flooring or on Class A, B, or C roof-covering material when roof curb is used. Although unit is weatherproof, guard against water from higher level runoff and overhangs. Flue vent discharge must have a minimum horizontal clearance of 4 ft from electric and gas meters, gas regulators, and gas relief equipment. Minimum distance between unit and other electrically live parts is 48 inches. Flue gas can deteriorate building materials. Orient unit such that flue gas will not affect building materials. Adequate combustion-air space must be provided for proper operation of this equipment. Be sure that installation complies with all local codes and Section 5.3, Air for Combustion and Ventilation, NFGC (National Fuel Gas Code), and ANSI (American National Standards Institute) Z223.1, and NFPA (National Fire Protection Association) 54 TIA-54-84-1. In Canada, installation must be in accordance with the CAN1- B149 installation codes for gas burning appliances. After unit is in position, remove rigging skids and shipping materials. MAXIMUM ALLOWABLE DIFFERENCE (in.) A-B 0.5 B-C 1.0 A-C 1.0 Step 5 — Install Flue Hood — Flue hood is shipped screwed to the burner compartment access panel. Remove from shipping location and using screws provided, install flue hood and screen in location shown in Fig. 7. For units size 004-006 being installed in California Air Quality Management Districts, which require NOx emissions of 40 nanograms/joule or less, a field-installed low NOx kit must be used. Fig. 3 — Unit Leveling Tolerances Step 6 — Install Gas Piping — Unit is equipped for use with type of gas shown on nameplate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1 entitled National Fuel Gas Code. In Canada, installation must be in accordance with the CAN1.B149.1 and CAN1.B149.2 installation codes for gas burning appliances. For natural gas applications, gas pressure at unit gas connection must not be less than 4 in. wg or greater than 13.0 in. wg while unit is operating. On 48TJ005,006,007 high heat units, the gas pressure at unit gas connection must not be less than 5 in. wg or greater than 13 in. wg while the unit is operating. For propane applications, the gas pressure must not be less than 5 in. wg or greater than 13 in. wg at the unit connection. Size gas sully piping for 0.5 in. wg maximum pressure drop. Do not use supply pipe small than unit gas connection. Support gas piping as shown in the table in Fig. 8. For example, a 3/4-in. gas pipe must have one field-fabricated support beam every 8 ft. Therefore, an 18-ft long gas pipe would have a minimum of 2 support beams, a 48-ft long pipe would have a minimum of 6 support beams. See Fig. 8 for typical pipe guide and locations of external manual main shutoff valve. CONDENSATE PAN (SIDE VIEW) DRAIN PLUG NOTE: Drain plug is shown in factory-installed position.

All wire larger than no. 18 AWG cannot be directly connected to the thermostat and will require a junction box and splice at the thermostat. Feed control wires through the raceway located between the condenser coil top cover and burner side panel. See Fig. 10. Connect control wires to corresponding screw terminals, the low-voltage connections located inside low-voltage access panel. See Fig. 12 for connections. The low-voltage connections provide the UL required clearance between high- and low-voltage wiring. HEAT ANTICIPATOR SETTINGS — Set heat anticipator settings at .14 amp for the first stage and .14 amp for secondstage heating, when available. Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (see Table 2). On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the legend for Table 2, Note 2 to determine the percent of voltage imbalance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Carrier warranty. FIELD CONTROL WIRING — Install a Carrier-approved accessory thermostat assembly according to installation instructions included with the accessory. Locate thermostat assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation instructions. Connect thermostat wires to terminal board. Route thermostat cable or equivalent single leads of colored wire from subbase terminals through connector on unit to lowvoltage connections (shown in Fig. 12). 9 208/230-3-60 460-3-60 (SIZE 007 ONLY) 208/230-1-60 575-3-60 (SIZE 007 ONLY) C COMP NEC TB — — — — 208/230-3-60 575-3-60, 460-3-60 (SIZES 004-006) LEGEND Contactor Compressor National Electrical Code Terminal Block Fig. 11 — Power Wiring Connections LEGEND AHA — Adjustable Heat Anticipator Field Wiring Factory Wiring Fig. 12 — Low-Voltage Connections 10 Table 2 — Electrical Data UNIT 48TF NOMINAL V-Ph-Hz 208/230-1-60 208/230-3-60 004 460-3-60 575-3-60 208/230-1-60 208/230-3-60 005 460-3-60 575-3-60 208/230-1-60 208/230-3-60 006 460-3-60 575-3-60 208/230-3-60 460-3-60 007 575-3-60 IFM TYPE Std Alt Std Alt High Std Alt High Std Alt High Std Alt Std Alt High Std Alt High Std Alt High Std Alt Std Alt High Std Alt High Std Alt High Std High Std High Std High VOLTAGE RANGE Min Max COMPRESSOR (ea) RLA LRA 187 254 16.2 96.0 187 254 10.2 75.0 414 508 4.4 40.0 518 632 3.7 31.0 187 254 23.3 118.0 187 254 15.4 90.0 414 508 8.3 45.0 518 632 6.4 36.0 187 254 28.8 147.0 187 254 16.3 114.0 414 508 7.4 64.0 518 632 6.2 62.0 187 254 23.6 146.0 414 508 10.6 73.0 518 632 8.5 58.4 OFM IFM (ea) FLA Qty Hp FLA 3.5 1/ 1 1.4 4 4.9 3.5 1/ 1 1.4 4.9 4 5.2 1.3 1/ 1 0.8 2.1 4 2.6 1.3 1/ 1 0.8 2.1 4 2.6 3.5 1/ 1 1.4 4 4.9 3.5 1/ 1 1.4 4.9 4 5.2 1.8 1/ 1 0.8 2.1 4 2.6 1.8 1/4 1 0.8 2.1 2.6 5.9 1/ 1 1.4 4 6.6 5.9 1/ 1.4 5.2 1 4 7.5 3.1 1/4 1 0.8 2.6 3.4 3.1 1/ 0.8 3.0 1 4 3.4 5.2 1/ 1 1.4 4 7.5 2.6 1/ 0.6 1 4 3.4 2.6 1 1 /4 0.6 3.4 LEGEND FLA HACR IFM LRA MCA MOCP NEC OFM RLA — — — — — — — — — COMBUSTION FAN MOTOR FLA .6 .6 .3 .3 .6 .6 .3 .3 .6 .6 .3 .3 .6 .3 .3 POWER SUPPLY MCA MOCP† 24.5/24.5 30/30 26.6/26.6 35/35 17.7/17.7 25/25 19.1/19.1 25/25 19.4/19.4 25/25 7.6 15 8.4 15 8.9 15 6.3 15 6.9 15 7.3 15 34.0/34.0 40/40 35.4/35.4 45/45 24.2/24.2 30/30 25.6/25.6 30/30 25.9/25.9 30/30 13.0 20 13.3 20 13.8 20 10.1 15 10.3 15 10.7 15 43.3/43.3 60/60 44.0/44.0 60/60 27.3/27.3 35/35 26.6/26.6 35/35 28.9/28.9 35/35 13.2 20 12.7 15 13.5 20 10.9 15 10.5 15 12.6 15 30.2/30.2 35/35 32.5/32.5 40/40 15.4 20 16.1 20 12.3 15 12.9 20 DISCONNECT SIZE* FLA LRA 23/23 106/106 26/26 111/111 17/17 85/85 19/19 90/90 19/19 109/109 7 48/48 8 48/48 9 57/57 7 35 8 37 7 45 32/32 129/129 34/34 133/133 23/23 101/101 25/25 105/105 25/25 124/124 13 51 13 53 13 62 10 41 11 42 10 50 42/42 161/161 42/42 184/184 29/29 128/128 26/26 148/148 29/29 174/174 13 72 12 81 13 94 11 58 10 66 11 76 29/29 180/180 32/32 205/205 15 90 16 103 13 72 14 82 Example: Supply voltage is 460-3-60.

If ventilation air is required, perform the following: 1. The indoor fan must be on to set the ventilation air. Either put the thermostat in the continuous fan mode or jumper the R and G terminals at the rooftop unit connection board. 2. Locate the minimum position (MIN POS) potentiometer. Turn the potentiometer full CCW to fully close the outdoor air dampers. Turn the potentiometer gradually clockwise (CW) to the desired position. See Fig. 38. 3. Replace the filter access panel. See Fig. 26. Ensure the filter access panel slides along the tracks and is securely engaged. 4. Calculate the minimum airflow across the EconoMi$er. a. Calculate % of outside air using the following formula. % Outdoor air through EconoMi$er Mixture Temp – Return Air Temp % Outdoor air = Outdoor Temp – Return Air Temp SUPPLY AIR TEMPERATURE SENSOR MOUNTING LOCATION SUPPLY AIR TEMPERATURE SENSOR Fig. 37 — Supply-Air Sensor Placement CO2 Control Set Up — If a CO2 sensor is not being used, proceed to the next section. If a CO2 sensor is being used, perform the following: 1. Determine the value at which you want the minimum position of the dampers to begin opening to allow a greater amount of outdoor air to enter. The range is 800 to 1,400 ppm. 2. Locate the CO2 SP (PPM) potentiometer and adjust to the desired set point. See Fig. 38. Mechanical Cooling Lockout — Determine the outdoor-air temperature at which you want the mechanical cooling (compressors) to be disabled. Locate the mechanical cooling lockout (MECH CLG LOCKOUT) potentiometer. To disable this feature, turn the potentiometer counterclockwise (CCW) to the OFF position. Otherwise, set the value between 10 and 60 F. Mechanical cooling will not operate when the outdoor air temperature is below this value. See Fig. 38. Dry Bulb Changeover Set Up — Determine the dry bulb changeover set point from Table 3. The settings are A, B, C and D. Locate the ECON SP potentiometer and set the dry bulb changeover set point. See Fig. 38. When the OAT is above this set point, the damper is limited to minimum position setting. b. Divide total CFM by percentage outdoor air, this gives outdoor air volume in CFM. 5. Turn on base unit power. NOTE: The EconoMi$er begins operation three minutes after power up. Personal Injury Hazard. Avoid possible injury by keeping fingers away from damper blades. 6.

Turn off power to the unit and install lockout tag. 3. Reverse any two of the unit power leads. 4. Reapply power to unit and recheck pressures. The suction and discharge pressure levels should now move to their normal start-up levels. NOTE: When the compressor is rotating in the wrong direction, the unit makes an elevated level of noise and does not provide cooling. Unit Preparation — Make sure that unit has been installed in accordance with these installation instructions and applicable codes. Return-Air Filters — Make sure correct filters are installed in filter tracks. See Table 1. Do not operate unit without return-air filters. Compressor Mounting — Compressors are internally Cooling — Set space thermostat of OFF position. To start unit, turn on main power supply. Set system selector switch at COOL position and fan switch at AUTO. position. Adjust thermostat to a setting below room temperature. Compressor starts on closure of contactor. Check unit charge. Refer to Service, Refrigerant Charge section, page 41. Allow unit to operate a minimum of 10 minutes before checking charge. Reset thermostat at a position above room temperature. Compressor will shut off. Evaporator fan will shut off after 30-second delay. TO SHUT OFF UNIT — Set system selector switch at OFF position. Resetting thermostat at a position above room temperature shuts unit off temporarily until space temperature exceeds thermostat setting. spring mounted. Do not loosen or remove compressor holddown bolts. Internal Wiring — Check all electrical connections in unit control boxes. Tighten as required. Ensure electrical wires do not come in contact with refrigerant tubing or sharp edges. Refrigerant Service Ports — To service refrigerant service ports, remove refrigerant service port access panel. See Fig. 43. Each unit system has 4 Schrader-type service gage ports: one on the suction line, one on the liquid line, and two on the compressor discharge line. Be sure that caps on the ports are tight. When a controls upgrade package is used, one Schrader-type valve is located under both the high-pressure switch and the low-pressure switch. High Flow Valves — Located on the compressor hot gas and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with o-rings located inside the caps. These valves can not be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur. Main Burners — Main burners are factory set and should require no adjustment. TO CHECK ignition of main burners and heating controls, move thermostat set point above room temperature and verify that the burners light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the thermostat setting below room temperature and verify that the burners and evaporator fan turn off. (Fan will turn off only if fan selector switch is in the AUTO. position and after a 45-second delay has elapsed.) Refer to Table 30 for the correct orifice to use at high altitudes.

To determine whether or not compressor is rotating in the proper direction: 1. Connect service gages to suction and discharge pressure fittings. 2. Energize the unit. 3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up. If the suction pressure does not drop and the discharge pressure does not rise to normal levels: 1.

Therefore, heat input rate should be reduced at higher altitudes. †Orifices available through your Carrier distributor. 37 Heating 1. Purge gas supply line of air by opening union ahead of gas valve. If gas odor is detected, tighten union and wait 5 minutes before proceeding. 2. Turn on electrical supply and open manual gas valve. 3. Set system switch selector at HEAT position and fan switch at AUTO. or ON position. Set heating temperature lever above room temperature. 4. The induced-draft motor will start. 5. After a call for heating, the main burners should light within 5 seconds. If the burner does not light, then there is a 22-second delay before another 5-second try. If the burner still does not light, the time delay is repeated. If the burner does not light within 15 minutes, there is a lockout. To reset the control, break the 24 v power to W1. ADJUST GAS INPUT — The gas input to the unit is determined by measuring the gas flow at the meter or by measuring the manifold pressure. Measuring the gas flow at the meter is recommended for natural gas units. The manifold pressure must be measured to determine the input of propane gas units. Measure Gas Flow (Natural Gas Units) — Minor adjustment to the gas flow can be made by changing the manifold pressure. The manifold pressure must be maintained between 3.4 and 3.6 in. wg. If larger adjustments are required, change main burner orifices following the recommendations of national and local codes. Unit must be operating with both W1 and W2 energized (high-fire). NOTE: All other appliances that use the same meter must be turned off when gas flow is measured at the meter. Proceed as follows: 1. Turn off gas supply to unit. Turn off electric supply to unit and install lockout tag. 2. Remove pipe plug on manifold (see Fig. 44) then connect manometer at this point. Turn on gas to unit. 3. Turn on electrical power. 4. Energize W1, and/or W2 at thermostat. Ensure gas valve, if 2-stage style, is in “High Fire.” Observe manifold pressure and proceed as follows to adjust gas input: 1. Remove cover screw over regulator adjustment screw on gas valve. 2. Turn regulator adjustment screw clockwise to increase gas input, or turn regulator adjustment screw counterclockwise to decrease input. Manifold pressure must be 3.5 in. wg while in high fire. INDUCEDDRAFT MOTOR MOUNTING PLATE ROLLOUT SWITCH BURNER SECTION FLUE EXHAUST VESTIBULE PLATE INDUCEDDRAFT MOTOR BLOWER HOUSING MANIFOLD PRESSURE TRAP (PIPE PLUG) GAS VALVE Fig. 44 — Burner Section Details 3. Turn on gas to unit. 4. Remove cover screw over regulator adjustment screw on gas valve. 5. Adjust regulator adjustment screw to the correct manifold pressure, 3.5 in wg. Turn adjusting screw clockwise to increase manifold pressure, or turn adjusting screw counterclockwise to decrease manifold pressure. 6. Replace cover screw. 7. Turn off gas to unit. Remove manometer from pressure tap. Replace pipe plug on gas valve, then turn on gas to unit. Check for gas leaks. 8. The evaporator-fan motor will turn on 45 seconds after the burners are ignited. 9. The evaporator-fan motor will turn off 45 seconds after thermostat temperature is satisfied. 10. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate. NOTE: The default value for the evaporator-fan motor ON/ OFF delay is 45 seconds. The Integrated Gas Unit Controller (IGC) modifies this value when abnormal limit switch cycles occur. Based upon unit operating conditions, the ON delay can be reduced to 0 seconds and the OFF delay can be extended to 180 seconds. When one flash of the LED is observed, the evaporator-fan ON/OFF delay has been modified. If the limit switch trips at the start of the heating cycle during the evaporator ON delay, the time period of the ON delay for the next cycle will be 5 seconds less than the time at which the switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan ON delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating. The evaporator-fan OFF delay can also be modified. Once the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan OFF delay will increase by 15 seconds. A maximum of 9 trips can occur, extending the evaporator-fan OFF delay to 180 seconds. To restore the original default value, reset the power to the unit. TO SHUT OFF UNIT — Set system selector switch at OFF position. Resetting heating selector lever below room temperature will shut unit off until space temperature falls below thermostat setting. Unsafe operation of the unit may result if manifold pressure is outside this range. Personal injury or unit damage may result. 3. Replace cover screw cap on gas valve. 4. Turn off gas supply to unit. Remove manometer from pressure tap and replace pipe plug on gas valve. Turn on gas to unit and check for leaks. Measure Manifold Pressure (Propane Units) — The main burner orifices on a propane gas unit are sized for the unit rated input when the manifold pressure reading is 3.5 in. wg. Ensure unit is operating in High-Fire operation mode (W1 and W2 energized) before adjusting manifold pressure. Proceed as follows to adjust gas input on a propane gas unit: 1. Turn off gas to unit. 2. Remove pipe plug on manifold (see Fig. 44), then connect manometer at this point. 38 Safety Relief — A soft solder joint at the suction service position of the economizer damper will be determined by the supply-air temperature. When the second stage of cooling is satisfied, the compressor and OFM will be deenergized. The damper position will be determined by the supply-air temperature. When the first stage of cooling is satisfied, there is a 30-second delay before the evaporator fan shuts off. The damper then moves to the fully closed position. When using a continuous fan, the damper moves to the minimum position. COOLING, UNITS WITH ECONOMI$ER — When the outdoor-air temperature (OAT) is above the ECON SP set point and the room thermostat calls for Stage 1 cooling (R to G + Y1), the indoor (evaporator) fan motor (IFM) is energized and the EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). After the thermostat is satisfied, the damper modulates to the fully closed position when the IFM is deenergized. When the OAT is below the ECON SP setting and the room thermostat calls for Stage 1 cooling (R to G + Y1), the EconoMi$er modulates to the minimum position when the IFM is energized. The EconoMi$er provides Stage 1 of cooling by modulating the return and outdoor air dampers to maintain a 55 F supply air set point. If the supply-air temperature (SAT) is greater than 57 F, the EconoMi$er modulates open, allowing a greater amount of outdoor air to enter the unit. If the SAT drops below 53 F, the outdoor air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the EconoMi$er maintains its position. If outdoor air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below. NOTE: Compressor has a 2-minute Minimum On, Minimum Off, and Interstage delay timer. 1. If Y1 is energized, and the room thermostat calls for Y2 (2-stage thermostat), the compressor and OFM are energized. The EconoMi$er damper is maintained at its current position. 2. If Y1 is energized for more than 20 minutes, and Y2 is not energized (whether or not a 2-stage thermostat is used), the compressor and OFM are energized. The EconoMi$er damper is maintained at its current position. 3. If Y1 is energized, and the compressor is already energized (see Step 2) and the room thermostat calls for Y2, the compressor continues to operate. 4. If the compressor is energized and the thermostat is satisfied, the compressor, the OFM, and IFM are deenergized and the EconoMi$er modulates closed. When the OAT is below the MECH CLG LOCKOUT set point, the compressors remain off. HEATING, UNITS WITH ECONOMI$ER — When the thermostat calls for heating, terminal W1 is energized. To prevent thermostat short-cycling, the unit is locked into the Heating mode for at least 1 minute when W1 is energized. The induceddraft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited and the damper moves to the minimum position. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the highfire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45-second time-off delay. The economizer damper then moves to the fully closed position. When using continuous fan, the damper will remain in the minimum position. Schrader port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building). Use backup wrench when tightening flare cap. High Flow Valves — Located on the compressor hot gas and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with O-rings located inside the caps. These valves cannot be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur. Ventilation (Continuous Fan) — Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuously to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second delay before the fan turns off. Operating Sequence COOLING, UNITS WITHOUT ECONOMIZER — When thermostat calls for cooling, terminals G and Y1 are energized, and the indoor (evaporator) fan motor (IFM), compressor, and outdoor (condenser) fan motor (OFM start. The OFM runs continuously while the unit is in cooling. When the thermostat is satisfied, compressor contactor (C) is deenergized and the compressor and OFM shut off. After a 30-second delay, the IFM shuts off. If the thermostat fan selector switch is the ON position, the evaporator motor will run continuously. HEATING, UNITS WITHOUT ECONOMIZER — When the thermostat calls for heating, terminal W1 is energized. To prevent thermostat short-cycling, the unit is locked into the Heating mode for at least 1 minute when W1 is energized. The induced-draft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45-second time-off delay. COOLING, UNITS WITH DURABLADE ECONOMIZER — When the outdoor-air temperature is above the outdoor-air thermostat (OAT) setting and the room thermostat calls for cooling, compressor contactor is energized to start compressor and the outdoor (condenser) fan motor (OFM). The indoor (evaporator) fan motor (IFM) is energized and the economizer damper moves to the minimum position. After the thermostat is satisfied, there is a 30-second delay before the evaporator fan turns off. The damper then moves to the fully closed position. When using continuous fan, the damper moves to the minimum position. When the outdoor-air temperature is below the OAT setting and the thermostat calls for cooling, the economizer damper moves to the minimum position. If the supply-air temperature is above 57 F, the damper continues to open until it reaches the fully open position or until the supply-air temperature drops below 52 F. When the supply-air temperature falls to between 57 F and 52 F, the damper will remain at an intermediate open position. If the supply-air temperature falls below 52 F, the damper will modulate closed until it reaches the minimum position or until the supply-air temperature is above 52 F. When the thermostat is satisfied, the damper will move to the fully closed position when using AUTO. fan or to the minimum position when using a continuous fan. If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling is integrated with mechanical cooling, providing two stages of cooling. Compressor and the condenser fan will be energized and the 39 SERVICE When servicing unit, shut off all electrical power to unit to avoid shock hazard or injury from rotating parts.

CONDENSATE DRAIN — Check and clean each year at start of cooling season. In winter, keep drain dry or protect against freeze-up. FILTERS — Clean or replace at start of each heating and cooling season, or more often if operating conditions require it. Replacement filters must be same dimensions as original filters. OUTDOOR-AIR INLET SCREENS — Clean screens with steam or hot water and a mild detergent. Do not use disposable filters in place of screens. 40 Fig. 48 — Condenser-Fan Adjustment NO CHARGE — Use standard evacuating techniques. After evacuating system, weigh in the specified amount of refrigerant. (Refer to Table 1.) LOW-CHARGE COOLING — Using Cooling Charging Charts, Fig. 49-52, vary refrigerant until the conditions of the appropriate chart are met. Note the charging charts are different from type normally used. Charts are based on charging the units to the correct superheat for the various operating conditions. Accurate pressure gage and temperature sensing device are required. Connect the pressure gage to the service port on the suction line. Mount the temperature sensing device on the suction line and insulate it so that outdoor ambient temperature does not affect the reading. Indoor-air cfm must be within the normal operating range of the unit. TO USE COOLING CHARGING CHART — Take the outdoor ambient temperature and read the suction pressure gage. Refer to chart to determine what suction temperature should be. If suction temperature is high, add refrigerant. If suction temperature is low, carefully recover some of the charge.
