All phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES. Should further information be desired or should particular problems arise which are not covered sufficiently fbr the purchaser's purposes, the matter should be referred to your installing dealer or local distributor. Heat Pumps with this unit. Please return to service infbrmation pack TOP DISCHARGE --- UNRESTRICTED 5 FT. ABOVE UNIT A, GENERAL NOTICE: These outdoor units, except for the TWPO6OD, may be used with indoor units equipped with Capillary Tube, Thermostatic Expansion Valve or the Accutron TM Flow Control Check Valve (F.C.C.V.) assembly for refrigerant flow control. The TWP06OD outdoor units are only approved with indoor units equipped with thermostatic expansion valve refrigerant controls. Check for transportation promptly, to the carrier, damage after unit is uncrated. any damage found to the unit. Report To determine the electrical power requirements of the unit, refer to the nameplate of the unit. The electrical power available must agree with that listed on the nameplate. The Weathertron ®Heat Pump has been designed and manufactured to withstand and operate in severe winter conditions. However, there are precautionary steps which should be taken at the time of installation which will help assure the efficient operation of the unit. It is recommended that these precautions be taken for units being installed in areas where snow accumulation and prolonged below freezing temperatures occur. 1. Units should be elevated 3 to 12 inches above the pad or rooftop, depending on local weather. This additional height will allow be tter dra inc_ge of snow and ice (melted during d@x)st cycle) prior to its refbeezin_. This should prevent a build-up of ice around the unit which occurs when unit is not elevated. Insure that drain holes in unit base pan are not obstructed preventing draining of defrost water. 2. If possible, avoid locations that are likely to accumulate snow drif_bs. If not possible, a snow drif_b barrier should be installed around the unit to prevent a build-up of snow on the sides of the unit and should be of sufficient distance from the unit to prevent restriction of airflow to and fi'om the unit. Also allow for proper maintenance space. The barrier should be constructed of materials which will blend in with the building design. 3. Avoid locating the unit where condensation and freezing of deli'ost vapor may annoy the customer. For instance, installing the unit under a bedroom, kitchen, or picture window may be annoying to the customer since condensate and fog will occur during the defrost cycle. 4. Avoid locating the unit under the eaves or other overhead structures as sizeable icicles may form and the unit may be damaged by these falling icicles. Since the manufacturer has a policy of continuous product improvement, it reserves the right to change specifications and design without notice © American Standard Inc. 1999 I ;TALLER'S B.

The support pad must NOT be in direct contact with any structure. The unit must be positioned a minimum of 12" from any wall or surrounding shrubbery to insure adequate airflow. A 30" clearance must be provided in front of control box (access panels) & any other side requiring service access to meet National Electrical Code. The unit must be far enough away from any structure to prevent excess roofrun-offwater from pouring directly on the unit. 5. The maximum indoor unit should TYPE 2.

If the indoor u nit is factory shipped with a diffbrent orifice size, the orifice must be changed to obtain system rated performance. 4. Provide a pull-thru hole of sufficient size to allow both liquid and gas lines plus fittings to clear. The location of this hole (if practical) should be just about the wall plate which is resting on the fbundation. IMPORTANT: The outdoor unit is shipped with the proper size orifice and a stick-on orifice size label in an envelope attached to the outdoor unit. Outdoor unit nameplate will have correct orifice size specified as BAYFCCV --- A for rated performance. 5. Be sure the tubing D.

To prevent a noise within the building structure due to vibration transmission from the refrigerant lines, the following precautions should be taken: a.

Use a Dry Nitrogen Purge and Brazing Alloy without flux when brazing the field line to the copper factory connection. Flow dry nitrogen into either valve pressure tap port, thru the tubing and out the other port while brazing. RING 8. Braze using accepted good brazing techniques. b.

OF GAS LINE Replace pressure hoses for evacuation. top Extreme caution should beex- ercised so the internal steel stem retaining ring is not damaged by backing out the valve stem when opening the valve. If the valve stem is forced out past the retaining ring, system pressure could force the valve stem out of the valve body. If the retaining ring is missing, do not attempt to open the valve.

OPERATIONAL The demand defrost control measures heat pump outdoor ambient temperature with a sensor located outside the outdoor coil. A second sensor located on the outdoor coil is used to measure the coil temperature. The difference between the ambient and the colder coil temperature is the ditI_rence or delta-T measuremerit. This delta-T measurement is representative of the operating state and relative capacity of the heat pump system. By measuring the change in delta-T, we can determine the need for defi'ost. The coil sensor also serves to sense outdoor coil temperature for termination of the defi'ost cycle. Final phases of this installation are the unit Operational and Checkout Procedures which are found on page 8 of this instruction. FAULT DETECTION A fault condition is indicated by the flashing light on the defl'ost control inside the heat pump control box. In normal operation, the defl'ost control light will flash once each second. If the light is flashing more than once per second or notat-all, refer to the service manual for that unit. PIN IDENTIFICATION (See Figure L. COMPRESSOR ODS-A thermistor AND CHECKOUT SUMP WILL BE BLOWN. PROCEDURES HEAT After all electrical wiring is complete, SET THE THERMOSTAT SYSTEM SWITCH IN THE OFF POSITION SO COMPRESSOR WILL NOT RUN, and apply power by closing the system main disconnect switch. This will activate the compressor sump heat. Do not change the Thermostat System Switch until power has been applied long enough to evaporate any liquid of HCFC-22 in the compressor (30 minutes for each pound of HCFC-22 in the system as shown on the nameplate). Following this procedure will prevent compressor damage at the initial startup. Record the "POWER APPLIED DATA" on the designated below: lines 6) 1.

OPERATIONAL CHECK IMPORTANT: To prevent compressor damage which may result from the presence of LIQUID refrigerant in the crankcase, these procedures should be followed at initial Start-Up and at anytime the power has been off for 12 hours or more. 1. Before proceeding with this "Operational Check," go to "Compressor Sump Heat Section" of this instruction to determine the time compressor heat has been "ON," and make entry d the designated lines, in Step 2. 2. Start-Up Time A.M./P.M. Time Lapse Power Applied Time Hours A.M./P.M. Minutes. 3. If Steps 1 and 2 cannot be used, then place thermostat's system switch in the "OFF" position and apply power by closing system disconnect switch. This energizes compressor heat and evaporates the liquid in the crankcase. TO EVAPORATE LIQUID ALLOW AT LEAST ONE-HALF HOUR PER POUND (HCFC-22), AS SHOWN ON UNIT NAMEPLATE. OPERATING PRESSURES: After the unit has operated in the cooling mode for a short period of time, install pressure gauges on the gauge ports of the discharge and suction line valves. Check the suction and discharge pressures and compare them to the normal operating pressures provided in the unit's Service Facts. NOTE: Use the pressures from Service Facts to determine the unit refrigerant charge. To charge the system accurately, use superheat charging, or pressures depending on flow control. 4.
