Lifting holes are provided in the base rails as shown in
Fig. 5 and 6. Refer to rigging instructions on the unit.
POSITIONING
-- Maintain clearance around and above the
unit to provide proper tdrflow and service access. See Fig. 6.

SLAB MOUNT (Horizontal Units Only) -- Provide a level
concrete slab that extends a minimum of 6 in. beyond the unit
cabinet on all sides. Inst_dl a grovel apron in front of the
outdoor coil air inlet to prevent grass and foliage fi_)m obstructing airflow.
NOTE: Holizont_d units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT -- When
the
curb
or
adapter cannot be used, support unit with sleeper rtfils using
unit curb or adapter support mea. If sleeper rails cannot be
used, support the long sides of the unit with a minimum of
3 equ_dly spaced 4-in. x 4-in. pads on each side.

Position the unit on the roof curb so that the following cleartraces me maintained: l/4-in, clearance between the roof curb
and base rails on each side and in front of the unit; 35/1(_-in.
clearance between the roof curb and the outdoor fan end of the
unit (see Fig. 1, section C-C).
Do not install the unit indoors. Do not locate the unit _fir
inlet near exhaust vents or other sources of contaminated all:
Although the unit is weatherproof, guard against water from
higher level runoff and overhangs.
After the unit is in position, remove the polyethylene shipping wrapper and rigging skid.

Step 2 --

Field Fabricate
Ductwork -- On vertic:d discharge units, secure _dlducts to the roof curb and building
structure. Do not connect dm m'ork to the unit. For horizontal
applications,
tield-supplied
flanges should be attached to
horizontal dischmge openings and all ductwork attached to the
flanges. Insulate and weatherproof all extern_fl ductwoN, joints,
and roof openings with counter flashing and mastic in accordance with applicable codes.

When using the standard end di'ain connection, make sure
the plug in the alternate bottom connection is tight before installing the unit.
To use the bottom drain connection for a roof curb inst_dlation, relocate the factory-inst_dled plug from the bottom connection to the end connection. The center diain plug looks like a stm
connection, bnt can be removed with a I/z-in. socket diive extension. See Fig. 3. The piping for the condensate di_dn and extermfl
trap can be completed after the unit is in place.
All units must have an extern_d trap for condensate chainage. Install a trap at least 4-in. deep and protect against freezeup. If di'ain line is installed downstream from the extern_d trap,

When inst_dling units, provide a disconnect

Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal inju U if
an electrical fault should occm_ This ground may consist of
electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when
installed in actor&race
with NEC (National Electrical
Code) ANSI (American
Nation_d Stand_uds Institute)/
NFPA (National Fire Protection Association) 70 latest yetu
and local electrical codes. Failure to follow this warning
could result in the installer being liable for personal inju U
of others.

Inst_dl field wiring as follows:
1. Inst_dl conduit through the side panel openings. For units
without electric heat, inst_dl conduit between the disconnect and control box.

FIELD POWER SUPPLY -- All units except
208/230-v
units are factory-wired for the voltage shown on the unit nameplate. If the 208/230-v unit is to be connected to a 208-v power
supply, the transformer must be rewired by disconnecting the
black wire from the 230-v l/4-in, male spade terminal on the
tmnsforlner and connecting it to the 208-v l/4-in, m_de spade
terminal from the transformel:
Refer to the unit label diagrmn for additional information.
Pigttfils tue provided for field wire connections. Use factorysupplied splices or a UL Underwriters' Laboratories) approved

per the NEC.

All field wiring must comply with the NEC and local requirements. In Canada, electrical connections must be made in
accor&mce with CSA (Canadian Stan&trds Association) C22.1
Canadian Electric_d Code Part One.

For units with electric heat, refer to Table 2 and Accessory
Installation Instructions.

During operation, voltage to compressor terminals must be
within range indicated on unit nameplate (see Tables 3A and
3B). On 3-phase units, voltages between phases must be balanced within 2%, and the current within 10%. Use the formula
shown in Tables 3A and 3B, Note 2 on page 11 to determine
the percentage 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 wammty.

*Two heater packages required to provide kW indicated.
rUse CRSINGLEOO8AOO for units with an electrical convenience

outlet.

NOTES:
1. The rated heater voltage is 240,480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.
2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW new = Heater kW rated x (unit power distribution voltage/rated heater voltage) 2
As an example:
For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v
kW new = 16 kW (218/240) 2
kW new = 12.8 kW (rating at 215 v)

for outdoor @ bulb
changeover control. The outdoor air and supply air temperature
sensors me included as standmd. For this control mode, the
outdoor temperature is compared to an adjustable set point
selected on the control. [f the outdoor-air temperature is above
the set point, the 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 dampers will
be controlled to provide free cooling using outdoor all: When
in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover
temperature set point is
controlled by the free cooling set point potentiometer located
on the control. See Fig. 32. The sc_fle on the potentiometer is A,

Damper Movement -- Damper movement trom full open to
full closed (or vice versa) takes 2112minutes.
Thermostats -- The EconoMi$er IV control works with conventional thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er IV control does not support space temperature
sensors. Connections are made at the thermostat terminal 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 dalnper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer
See Fig. 32. 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 allows file damper to reach the appropriate position to avoid unnecessary fan overload.

Occupancy Control -- The facto U default configuration for
the EconoMi$er IV control is occupied mode. Occupied status
is provided by the black jumper fiom terminal TR to terminal
N. When unoccupied mode is desired, inst_dl a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 26. When the timeclock contacts are closed, the
EconoMi$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. 32. The minimum damper position maintains the minimum airflow into the building during the occupied period.
When using demand ventilation, the minimum dalnper 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 ventilation control is not being used, the
minimum position potentiometer should be used to set the occupied ventilation position. The maximum demand ventilation
position should be turned fully clockwise.
Adjust the minimum position potentiometer
to allow the
minimum amount 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 position setting, perform the
following procedure:
1. Calculate the appropriate mixed air temperature
following formula:
OA
RA
(Tox 1---_7) +(TRx 1-]Ti-(]-)=TM

Demand Controlled Ventilation (DCV) -- When using the
EconoMi$er 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 ev_duated for
design conditions. The maximum damper position must be calculated to provide the desired fresh air
Typically the maximum ventilation rate will be about 5 to
10% more than the typical cfin required per person, using
norm_d outside air design criteria.
A proportional anticipato U 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
machedi 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.
OA

(To x 1--_) + (TR x 1--_) = TM

using the

As an example, if local codes require 10% outdoor
during occupied conditions, outdoor-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 determine the occupied or
maximum venfihttion rote to the building. For example, an output of 3.6 volts to the actuator provides a base ventihttion 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. 37
to determine the maximum setting of the CO2 sensoc For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 37 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
EconoMiSer IV controller will output the 6.7 volts from the

the supply air sensor to termimds T and TI.

Remote control of the EconoMiSer IV damper is desirable
when requiring

If a

FOR FAN PERFORMANCE

1. Fan performance is based on clean filters and wet coil data.
2. Extensive motor and electrical testing on these units ensures
that the full range of the motor can be utilized with confidence.
Using fan motors up to the wattage ratings shown will not result
in nuisance tripping or premature motor failure. Unit warranty
will not be affected. For additional information on motor performance Table 9.

START-UP
Unit Preparation-

F;filure to observe the following warnings could result in
serious personal injuu:
1. Follow recognized safety practices and wear protective goggles when checking or servicing refrigerant
system.
2. Do not operate the compressor or provide any electric
power to the unit unless the compressor
terminal
cover is in place and secured.
3. Do not remove the compressor terminal cover until all
electrical sources are disconnected.

b.

Inspect for oil at all refrigerant tubing connections
and on the unit base. Detecting oil generally indicates a refrigerant
leak. Leak-test all refrigerant
tubing connections using an electronic leak detector, halide torch, or liquid-soap solution.

HIGH FLOW REFRIGERANT
VALVES -- Two high flow
valves may be located on the hot gas tube coming out of the
compressor and the suction tube going into the compressol:
L;uge black plastic caps identify these valves with O-rings
inside screwing the cap and onto a brass body. No field access
to these wdves is available at this time. Ensure the plastic caps
remain on the valves and are tight or the possibility of refrigerant leakage could occur

Compressor Rotation

-- It is important to be celtain
that the scroll compressor
(size 012 only) is rotating in the
proper direction. To determine whether or not the compressor
is rotating in the proper direction:
1. Connect service gages to the suction and disch;uge
sure fittings.
2. Energize the compressor
3. The suction pressure should diop and the discharge
sure should rise, as is normal on any start-up.

pres-

If the suction pressure does not drop and the discharge
sure does not rise to normal levels:

pros-

1. Note that the indoor fan is probably also rotating
wrong direction.
2. Turn off power to the unit and tag disconnect.
3. Reverse any two of the unit power leads.
4. Turn on power to the unit. Re-energize compressoc

in the

pres-

The suction and discharge pressme levels should now move
to their normal strut-up levels.
NOTE: When the compressor
is rotating in the wrong
direction, the unit makes more noise and does not provide
heating/cooling.
Cooling
-- To stm-t the unit, turn on main power supply. Set
the system selector switch at COOL position and the fan switch
at AUTO position. Adjust the thermostat to a setting below room
temperature. The compressor st_uts on closure of the contactol:
Check the unit charge. Refer to Refrigerant
on page 48.

Verify the following conditions:
a. Make
sure that the outdoor-fan
blades
are
correctly
positioned
in the fan orifice. Refer to
Outdoor-Fan
Adjustment
section on page 48 for
more details.

c.

hold-

-- Each refiigerant system
has 3 Schmder-type service gage ports: One on the suction line,
one on the cooling mode liquid line, and one on the compressor
discharge line. Be sure that the caps on the ports are tight.
The port on the cooling mode liquid line and one port on the
discharge line have protective devices installed on them.

Inspect the coil fins. If damaged during shipping
and handling, carefully straighten the fins with a
fin comb.

Make sure that an air filter(s)

Compressorsare internally

Refrigerant Service Ports

Inspect all field-wiring
and factory-wiring
connections. Be sure that connections
are completed
and tight. Ensure that electrical
wires do not
contact refrigerant tubing.

Heating

--

To start the unit, turn on tile main power supply.

If field-installed accesso U CO2 sensors
gu'e connected to the
EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases
above the CO2 set point, the minimum position of the &_mper
will be increased proportiomdly. As the CO2 level decreases
because of the increase in fresh all; the outdoo>air damper will
be proportionally closed. Damper position will follow the higher demand condition from DCV mode or free cooling mode.

Set the thermostat at HEAT position at a setting above room
temperature, the fan at AUTO position.
The first stage of the thermostat energizes the indoor-fan
motor, compressoL and outdoor fan; the second stage energizes
electric heater elements, if installed. Check the heating effects
at the air supply grille(s).
If the accessoiN electric heaters do not energize, reset limit
switch (located on indoor-fan scroll) by pressing the button
located between terminals on the switch.

Damper movement from full closed to full open (or vice
versa) will take between I lh and 2 lh minutes.
If free cooling can be used as determined fl_)m the appropriate changeover command (switch, dlN bulb, enthalpy curve,
differential din bulb, or differential enthalpy), a c_dl 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
As the supply-air temperature drops below the set point
range of 50 to 55 F. the control will modulate the outdoo>air
&_mpers closed to maintain the proper supply-air temperature.
HEATING. UNITS WITH ECONOMI$ER
IV -- When the
room temperature calls for heat, the heating controls am energized as described in the Heating, Units Without Economizer
section. When the thermostat
is satisfied, the economizer
&_mper moves to the minimum position.
COOLING.
UNITS WITH ECONOMISER2,
PREMIERLINK TM CONTROL AND A THERMOSTAT
-- When free
cooling is not available, the compressors will be controlled by
the PremierLink control in response to the YI and Y2 inputs
from the thermostat.

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

soft solder joint on the suction line at
the loss-of-chtuge/low-pressure
fitting provides pressme relief

HEATING, UNITS WITHOUT ECONOMIZER
-- Upon a
request for heating from the space thermostat, terminal WI will
be enelgized with 24 v. The IFC, outdoor-fan contactor (OFC),
CI, and C2 will be energized. The reversing valves switch position and the indoor fan, outdoor fan, compressor no. 1, and
compressor no. 2 are energized.
If the space temperature continues to fall while WI is energized, W2 will be energized with 24 v, and the heater contactor(s) (HC) will be energized, which will energize the electric
heater(s).

When free cooling is awtilable the PremierLink control will
control the compressors and economizer to provide a supplyair temperature determined to meet the YI and Y2 calls from
the thermostat using the following three routines. The three
control routines are based on OAT. where:

When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized.
Upon a lilrther rise in space temperature,
WI will be
deenergized,
and the reversing valve solenoids (RVSI and
RVS2) will be energized.
COOLING. UNITS WITH ECONOMISER
IV -- When free
cooling is not available, the compressol_ will be controlled by
the zone thermostat.
When free cooling is available, the
outdoor-air damper is modulated by the EconoMiSer IV control to provide a 50 to 55 F supply-air temperature into the
zone. As the supply-air temperature fluctuates above 55 or
below 50 E the dmnpers will be modulated (open or close)
to bring the supply-air temperature back within set point limits.
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.

Above 50 F supply-air temperature, the dmnpers will modulate fiom 100% open to the minimum open position. From 50 F
to 45 F supply-air temperature, the &tmpers will maintain at
the minimum open position. Below 45 F the dampers will be
completely shut. As the supply-air temperature rises, the dampers will come back open to the minimum open position once
the supply-air temperature rises to 48 E
If optional power exhaust is inst_dled, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.

The economizer set point will always be at least one degree
below the cooling set point, allowing for a smooth transition
from mechanical
cooling with economizer
assist, back to
economizer
cooling as the cooling set point is achieved.
The compressors
may be used for initial cooling then the
PremierLink controller will modulate the economizer using an
error reduction calculation to hold the space temperature
between the heating and cooling set points. See Fig. 42.
The controller uses the following
