SAFETY

CONSIDERATIONS

Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electric_d components. Only trained and qualified service personnel should
install, repair, or service at>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 at>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.

Manufacturer

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 1/2 psig, it must be replaced
before use. When pressure testing fieldsupplied 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 a lockout tag. Electrical shock could c_mse personal injury.

INSTALLATION
Unit is shipped in the vertical duct configuration. To convert
to horizont_d configuration, remove and save screws fi_m side
duct opening covers and remove covers. Using the same
screws, install covers on veriical duct openings with the
insulation-side down. Seals around duct openings must be
tight. See Fig. 1.
Confimt before installation of unit that voltage, mnperage
and circuit protection requirements listed on unit &tta plate
agree with power supply provided.
Step 1 -- Provide

ROOF CURB -- Assemble and install accesso U roof curb in
accor&mce 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 accesso O" thru-the-boltom power and gas connection package must be installed b@re the unit is ,wt on the roo/ curb. If
field-installed (thin-the-roof curb) gas connections tue desired,
use factory-supplied
3/4-in. pipe coupling and gas plate assembly to mount the thin-the-roof curb connection to the roof crag.
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: Tile gasketing of tile unit to tile roof curb is ]
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 2. hnproperly applied gasket can
result in tdr leaks and pool unit performance.

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 lequiled.
SLAB MOUNT (Horizontal
Units Only) -- Provide a level
conclete slab that extends a minimum of 6 in. beyond unit
cabinet. Install a gravel apron in front of condenser coil air inlet
to prevent gross and foliage from obstructing airflow.
NOTE: Horizontal

Field Fabricate

These units tue designed for a minimum continuous heating
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 F (@ bulb), such as when used with a
night set-back thermostat. To operate at lower return-air temperatures, a field-supplied outdoor air temperature control must
be used to initiate both stages of heat when the temperature is
below 45 E Indoor comfort may be compromised when these
lower air temperatures are used with insufficient heating temperature rise.

Step 3 --

Install External

Trap for Condensate

Drain

-- The unit's 3/4-in. condensate drain connections are
located on the bottom and side of the unit. Unit discharge connections do not deterraine the use of drain connections; either
dnun connection
can be used with vertic;d or horizont;d
applications.

ALTERNATE UNIT SUPPORT (Curb or Slab Mount) -- A
non-combustible
sleeper rail can be used in the unit curb support tuea. If sleeper rails cannot be used, support the long sides
of the unit with a minimum of 3 equally spaced 4-in. x 4-in.
pads on each side.

Step 2 --

A minimum clearance is not required around ductwork.
Cabinet return air static pressme (a negative condition) shall
not exceed 0.35 in. wg with economizer or 0.45 in. wg without
economizeE

When using the standard side &'ain connection, make sure
the plug (Red) in the ;alternate bottom connection is tight before
inst;dling 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. The center &'ain plug looks
like a stm" connection, however it can be removed with a l/2-in.
socket drive extension. See Fig. 4A. The piping for the condensate &'ain and external trap can be completed after the unit is in
place. See Fig. 4B.

Ductwork

-- Secure all
ducts to roof curb and building structure on vertical ducted
units. Do not connect du(_'ork to unit. For horizontal applications, field-supplied flanges should be attached to horizontal
duct 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
accor&mce with applicable codes.
Ducts passing through an unconditioned

outdoor temperature is compared to an adjustable set point
selected on file control. If the outdoor-air temperature is above
file set point, file EconoMiSer IV will adjust the outdoor-air
dampers to minimum position. If the outdoor-air temperature is
below the set point, the position of the outdoor-air &tmpers will
be controlled to provide flee cooling using outdoor till: When
in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover
temperature set point is

MOUNTING

In this mode of operation, the outdoor-tfir temperature is
compared to the leturn-air temperature and the lower temperature tfirstream is used for cooling. When using this mode of
changeover control, turn the enth_dpy setpoint potentiometer
fully clockwise to the D setting. See Fig. 33.
Outdoor Enthalpy Changeover
-- For enthalpy control, accessory enthalpy sensor (p_ut number HH57AC078)
is required. Replace the standard outdoor chy bulb temperature sensor with the accessory enthalpy sensor in the same mounting
location. See Fig. 20. When the outdoor air enthalpy rises
above the outdoor enthalpy changeover set point, the outdoorair damper moves to its minimum position. The outdoor
enthalpy changeover set point is set with the outdoor enthalpy
set point potentiometer on the EconoMiSer IV controller The
set points are A, B, C, and D. See Fig. 36. The factory-installed
620-ohm jumper must be in place across terminals SR and SR+

Differential Enthalpy Control
-- For differential
enthalpy
control, the EconoMiSer IV controller uses two enthalpy sensors (HH57AC078
and CRENTDIF004A00),
one in the outside air and one in the leturn air duct. The EconoMiSer [V
controller comptues the outdoor air enthalpy to the return air
enthalpy to determine
EconoMiSer
IV use. The controller
selects the lower enth_dpy air (return or outdoor) for cooling.
For example, when the outdoor tfir has a lower enthalpy than
the return tfir. the EconoMi$er IV opens to bring in outdoor air
for free cooling.

Sensor Maximum Range Setting

Damper Movement -- Damper movement trom full open to
full closed (or vice versa) takes 2112minutes.
Thermostats -- The EconoMiSer IV control works with conventiomd thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMiSer IV control does not support space temperature
sensors. Connections are made at the thermostat termimd connection board located in the main control box.

Exhaust Set Point Adjustment
-- The exhaust set point will
determine when the exhaust fan runs based on dmnper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer
See Fig. 33. The set point represents the damper position above
which the exhaust fans will be turned on. When there is a call
for exhaust, the EconoMiSer IV controller provides a 45 _+15
second delay before exhaust fan activation to allow the dampers to open. This delay _fllows file damper to reach the appropriate position to avoid unnecessaly fan overload.

Occupancy Control -- The facto U default configuration for
the EconoMi$er IV control is occupied mode. Occupied status
is provided by the black jumper flom terminal TR to terminal
N. When unoccupied mode is desired, inst_dl a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 27. When the timeclock contacts are closed, the
EconoMi$er IV control will be in occupied mode. When the
timeclock contacts are open (removing the 24-v signal from
terminal N), the EconoMi$er IV will be in unoccupied mode.

Minimum Position Control -- There is a minimum damper
position potentiometer on the EconoMiSer [V controllel: See
Fig. 33. The minimum damper position maintains the minimum airflow into the building during the occupied period.
When using demand ventihttion, the minimum dmnper position represents the minimum ventilation position for VOC
(volatile organic compound)
ventilation requirements.
The
maximum demand ventilation position is used for fully occupied ventilation.
When demand

Demand Controlled Ventilation (DCV) -- When using the
EconoMiSer IV for demand controlled ventilation, them are
some equipment selection criteria which should be considered.
When selecting the heat capacity and cool capacity of the
equipment, the maximum ventilation rote must be evaluated for
design conditions. The maximum damper position must be calculated to provide the desired fresh ail:
Typically the maximum ventilation rate will be about 5 to
10% morn than the typical chn required per person, using normid outside air design criteria.

ventilation control is not being used, the
potentiometer should be used to set the ocposition. The maximum demand ventilation
turned fully clockwise.

Adjust the minimum position potentiometer
to allow the
minimum mnount of outdoor aik as required by local codes, to
enter the building. Make minimum position adjustments with
at least 10 F temperature difference between the outdoor and
return-air temperatures.
To determine the minimum
following procedure:

position

setting,

perform

1. Calculate the appropriate mixed air temperature
following formula:
OA
RA
(Tox I--F6_) +(TRx 1-Tff6-)=TM

A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum
ventilation rate that is greater than the required ventilation rate
for maximum occupancy. A proportional-anticipato U strategy
will cause the fresh air supplied to increase as the room CO2
level increases even though the CO2 set point has not been
reached. By the time the CO2 level roaches the set point, the
damper will be at maximum ventilation and should maintain
the set point.
In order to have the CO2 sensor control the economizer
damper in this manner, fil.'stdetermine the damper voltage output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contmninants during unoccupied periods. The following equation may be used to determine
the percent of outside-air entering the building for a given
damper position. For best results there should be at least a
10 degree difference in outside and return-air temperatures.

the

using the

To = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature
RA = Percent of Return Air
TM = Mixed-Air

Temperature

As an example, if local codes require 10% outdoor
during occupied conditions, outdoor-air temperature

CarefiJlly adjust the minimum position potentiometer
until the measured supply air temperature matches the
calculated value.

TM = Mixed-Air Temperature
Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position.
The same equation can be used to deterlnine the occupied or
maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate
of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 38
to determine the maximum setting of the CO2 sensol: For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 38 to find the point when
the CO2 sensor output will be 6.7 volts. Line up the point on the
graph with the left side of the chart to determine that the range
configuration for the CO2 sensor should be 1800 ppm. The

6. Reconnect the supply _firsensor to termimds T and TI.
Remote control of the EconoMi$er IV damper is desirable
when requiring additiomd temporm-y ventilation. If a
field-supplied remote potentiometer (Honeywell part number
$963B1128) is wired to the EconoMi$er IV controllek the
minimum position of the damper can be controlled from a mmote location.
To control the minimum damper position remotely, remove
the factory-installed jumper on the P and PI terminals on the
EconoMi$er IV controllel: Wire the field-supplied potentiometer to the P and PI terminals on the EconoMi$er IV controller.
See Fig. 37.

*Motor drive range: 875 to 1192 rpm. All other rpms require a fieldsupplied drive.

GENERAL NOTES FOR FAN PERFORMANCE
1. Values include losses for filters, unit casing, and wet coils. See
Table 9 for FlOP static pressure information.
2. Performance data is based on clean filters and a wet coil.
3. Extensive motor and electrical testing on these units ensures
that the full range of the motor can be utilized with confidence.
Using the fan motors up to the wattage ratings shown will not
result in nuisance tripping or premature motor failure. Unit

DATA TABLES

warranty will not be affected. See Evaporator-Fan Motor Performance data in Table 8 on page 29 for additional information.
4. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative for details.
5. Interpolation is permissible. Do not extrapolate.

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
occm: 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 stm-t 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.

Dalnper movement from full closed to full open (or vice
versa) will take between 11/2and 21/2 minutes.
If free cooling can be used as determined fi_m the appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), a call for cooling
(YI closes at the thermostat) will cause the control to modulate
the dampers open to maintain the supply air temperature set
point at 50 to 55 E

TO SHUT OFF UNIT -- Set system selector switch at OFF
position. Resetting heating selector lever below room temperature will temponuily shut unit off until space temperature falls
below thermostat setting.

As the supply-air temperature drops below the set point
range of 50 to 55 F. the control will modulate the outdoor-air
&tmpers closed to maintain the proper supply-air temperature.

short-cycling,
the unit is locked into the
Heating mode for at least 1 minute when WI is energized. The
induced-draft

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-file solenoid on the main gas
valve (MGV) is energized. When the thermostat is satisfied
and WI is deenergized, the IFM stops after a 45-second timeoff delay.

Integrated EconoMiSer IV operation on single stage units

For EconoMiSer IV operation, there must be a thermostat
call for the fan (G). This will move the damper to its minimum
position during the occupied mode.

If the increase in cooling capacity causes the supply-air temperature to drop below 45 F, then the outdoor-air &tmper position will be liflly closed. If the supply-air temperature continues to ftdl, the outdoor-air dmnper will close. Control leturns to

economizer
cooling as the cooling set point is achieved.
The compressors

If any of the above conditions are not met, the economizer
submaster reference (ECSR) is set to maximum limit and the
damper moves to minimum position. The operating sequence
is complete. The ECSR is recalculated every 30 seconds.
If an optional power exhaust is installed, as the outdoor-air

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

the IFM stops after a
45-second time-off delay unless G is still maintained.
COOLING.
UNITS WITH ECONOMISER2,
PREMIERLINK CONTROL
AND A ROOM SENSOR -- When free
cooling is not available, the compressors will be controlled by
the PremierLink controller using a PID Error reduction calculation as indicated by Fig 42.
The PremierLink controller will use the following information to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT. SAT. and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy
must be LOW (may be jumpered
if and
enthalpy sensor is not available).
• Economizer
position is NOT forced.
When free cooling is available, the outdoor-air dalnper is positioned through the use of a Proportional Integral (PlD) control
process to provide a calculated supply-air temperature into the
zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in Fig. 43.

The PremierLink
control will integrate the compressol:s
stages with the economizer based on simihu logic as the three
routines listed in the previous section. The SASP will float up
and down based on the error reduction calculations that comptue space temperature and space set point.
When outside-air temperature conditions require the economizer to close for a compressor
stage-up sequence, the
economizer control integrator is reset to zero after the stage-up
sequence is completed. This prevents the supply-air temperature from dropping too quickly and creating a freeze condition
that would make the compressor turn off prematurely.

A functional view of the EconoMi$er is shown in Fig. 55.
Typical settings, sensor ranges, and jumper positions are
also shown. An EconoMi$er IV simulator progrmn is available
fiom Carrier to help with EconoMi$er
IV training and
troubleshooting.

Connect a 9-v battery to AQ (positive node) and AQl
(negative node). The LED for both DCV and Exhaust
should turn on. The actuator should drive to between 90
and 95% open.

Turn the Exhaust potentiometer
CW until the Exhaust
LED turns off. The LED should turn off when the
potentiometer is approximately 90%. The actuator should
remain in position.
Turn the DCV set point potentiometer CW until the DCV
LED turns off. The DCV LED should turn off when the
potentiometer is approximately 9 v. The actuator should
chive fully closed.
