Step 3 -- Rig and Place Unit -- Inspect unit for transportation &image. See Tables 1-3 for physical data. File any
claim with transportation
Disconnect gas piping from unit when pressure testing at
pressure greater than 0.5 psig. Plessmes
greater than
0.5 psig will cause gas valve damage resulting in hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it must be replaced before use. When pressme
testing field-supplied gas piping at pressures of 0.5 psig or
less, a unit connected to such piping must be isolated by
closing the manual gas v_dve(s).
IMPORTANT:
Units have high ambient
temperature]
operating limits. If limits are exceeded, the units will automatically lock the compressor out of operation. Manual
reset will be required to restart the compressol:
All panels must be in place when rigging. Unit is not
designed for handling by fork truck. Dmnage to unit may
result.

Unit Support
ROOF CURB -- Assemble or install accessory roof curb in
accor&mce with instructions shipped with this accessory. See
Fig. 1. Install insulation, cant strips, roofing, and counter flashing as shown. Ductwork can be installed to roof curb before
unit is set in place. Ductwork must be attached to curb and not
to the unit. Curb must be level. This is necessary to permit unit
drain to function properly. Unit leveling tolerance is _+J/l(_in.
per line,u ft in any direction. Refer to Accessory Roof Curb Inst',_lation Instructions for additional information as required.
When accessory roof curb is used, unit may be installed on
class A, B, or C roof covering materi_d. Carrier roof curb accessories are for flat roofs or slab mounting.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasket with the roof
curb as shown in Fig. 1. Improperly applied gasket can also
result in air leaks and poor unit performance. Do not slide
unit to position on roof curb.
ALTERNATE UNIT SUPPORTWhen a curb cannot be
used, install unit on a noncombustible
surface. Support unit
with sleepeLs, using unit curb support area. If sleepers cannot
be used, support long sides of unit with a minimum of 3 eqmflly spaced 4-in. x 4-in. pads on each side.
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 fi_mt of condenser coil air inlet to
plevent gross and foliage from obstructing airflow.
NOTE: Horizontal

units may be installed
agency.
Do not diop unit; keep upright. Use spreader baLs over unit
to prevent sling or cable damage. Rollers may be used to move
unit across a roof. Level by using unit fralne as a leference;
leveling tolerance is _+1/1(_ in. per linetu ft in any direction. See
Fig. 3 for additional information. Unit rigging weight is shown
in Fig. 3.
Four lifting holes tue provided in the unit base mils as
shown in Fig. 3. Refer to rigging instructions on unit.
POSITIONING
-- Maintain clearance, per Fig. 4, around and
above unit to provide minimum distance from combustible
materials, proper airflow, and service access.
Do not inst_dl unit in an indoor location. Do not locate air
inlets near exhaust vents or other sources of contaminated ai_:
For proper unit operation, adequate combustion and ventilation
air must be provided in accordance with Section 5.3 (Air for
Combustion and Ventilation) of the Natiomd Fuel Gas Code,
ANSI Z223.1 (American National Standmds Institute).
Although unit is weatherproof,
higher level runoff and overhangs.
guard against
water from
Ix)cate mechanical diaft system flue assembly at least 4 ft
from any opening through which combustion products could
enter the building, and at least 4 ft from any adjacent building
(or per local codes). When unit is located adjacent to public
w_dkways, flue assembly must be at least 7 ft above grade.
ROOF MOUNT -- Check building codes for weight distribution requirements. Unit operating weight is shown in Table 1.
INSTALLATION
ONTO CURBThe 48HJ units are designed to fit on the accessory full perimeter curb. Correct
placement of the unit onto the curb is critical to operating performance. To aid in correct positioning, 3/s-in. diameter locating holes have been added to the unit base rails. When placing
the unit, these holes should line up with the roof curb edge as
shown in Fig. 5 and 6, to assure proper duct opening alignment.
For placement on the roof curb, use the alignment holes located
approximately 2-in. fiom the end of the base rail on the return
end of the unit. See labels on the side of the unit for more
details.
on a roof curb if
Step 2 -- Remove Shipping Rails
-- Remove shipping rails prior to lowering unit onto roof curb. See Fig. 2. The
rails are attached to the unit at both the return end and condenser end. Remove the sclews from both ends of each rail. Be
c_u'eful not to drop the rails onto gray surface that could be
dmnaged. Disc_ud the rails. It is important to replace the sclews
into the unit to avoid any air or water leakage.
Do not allow the shipping rail to drop on the roof surface.
Dmnage to the roof surface may result.
Do not slide unit to position it when it is sitting on the curb.
Curb gasketing material may be &_maged and leaks may
result.

These units are designed for a minimum continuous returnair temperature in heating of 50 F (dry bulb), or an intermittent
operation down to 45 F (di_ 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 R Indoor comfort may be compromised
when these lower air temperatures
are used with insufficient heating temperature rise.

filter retainel: The filters can then be removed, cleaned, or
replaced. Install the filters by reversing the procedure.
MANUAL DAMPER ASSEMBLY-For units equipped
with manual dampers, the assembly process is similar to the
outdoor air hood for units with economizers. There me two
slide dampers shipped with the unit to _fllow for manual setting
of the outside air volume. When assembling the hood, place
one of the manual slide dampers in each of the end positions
and the remaining filter in the center position. The manual
dampel.s can then be moved to the appropriate position and
then locked into place using the screws mounted in the adjustment slots. See Fig. 20.

IMPORTANT: Unit power must be on for 24 hom.'sprior
to start-up. Otherwise, damage to compressor may
result.
Compressor
Phasing
hnproper wiring will cause compressor stoppage and may
cause equipment damage. Correct wiring by switching
leads as indicated below.
On 3-phase units, it is important to be certain the compressors are rotating in the proper direction. To determine whether
or not compressors are rotating in the proper direction, use a
phase-rotation
meter on the unit input power to check for
L I -L2-L3 or clockwise rotation. If the compressor is rotating in
the wrong direction, the suction pressure will not diop and the
discharge pressure will not rise.
NOTE: Indoor or outdoor fan rotation direction may not
indicate proper input power phase sequence, as some 3-phase
units use single-phase fan motors. Check fan rotation where
applicable.

GENERAL NOTES FOR TABLES 5-22
1. Static pressure losses (i.e., EconoMi$er IV) from Table 26 must
be added to external static pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing
losses. See Table 26 on page 39.
4.
Extensive motor and drive testing on these units ensures that
the full horsepower and watts range of the motor can be utilized
with confidence. Using the fan motors up to the watts or bhp
rating shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire size. Contact your
Carrier representative for details.

ECONOMI$ER
IV CONTROLLER
WIRING AND OPERATIONAL MODES -- Determine file EconoMiSer IV control
mode befole set up of the control. Some modes of operation may
require diffelent sensors. Refer to Table 28. The EconoMi$er IV
is supplied from the factory with a supply-air temperature
sensor _md an outdoor air temperature sensoc This allows for
operation of file EconoMiSer IV with outdoor air dly bulb
changeover control. Additional accessories can be added to
allow for different types of changeover control and operation
of the EconoMiSer IV and unit.
Optional
EconoMi$er IV -- SeeFig. 23 for EconoMi$er
IV component locations. The optional EconoMiSer IV comes
fiom the factory fully wiled and assembled. No field wMng or
assembly is requiled for stand;u'd outdoor dly bulb changeover
operation. Field wiring of accessory sensors is lequiled for
diffelent operational modes.
ECONOMISER
IV STANDARD SENSORS
Outdoor Air Temperature
(OAT) Sensor -- The outdoor air
temperature sensor (HH57AC074)
is a 10 to 20 mA device
used to measure file outdoor-air temperatme. The outdoor-_dr
temperature is used to determine when the EconoMi$er W can
be used for free cooling. The sensor is factory-installed
on the
EconoMi$er IV in the outdoor airstremn. See Fig. 24. The operating range of temperature measurement is 40 to 100 E
Outdoor Dry Bulb Changeover
-- The standmd controller is
shipped from the factory configured
for outdoor chT bulb
changeover control. The outdoor air and supply-air temperature
sensors abe included as stan&ud. For this control mode, the outdoor temperature is compmed to an adjustable set point selected
on the control. If the outdoor-air temperature is above the set
point, the EconoMiSer IV will adjust the outdoor-air dmnpers to
minimum position. If the outdoor-air temperature is below the
set point, file position of the outdoor-air dampel.s will be controlled to provide fiee cooling using outdoor ail: When in this
mode, the LED next to the free cooling set point potentiometer
will be on. The changeover temperatme set point is controlled
by file free cooling set point potentiometer located on the control. The sc_de on the potentiometer is A, B, C, and D. See
Fig. 25 for the conesponding temperatme changeover values.
Supply-Air Temperature
_SAT) Sensor
-The supply-_dr
temperature sensor is a 3 K thermistor located at the outlet of
the indoor fan. See Fig. 24. This sensor is factory installed. The
operating range of temperature measurement is 0 ° to 158 E
The temperature sensor is a short probe with blue wires
running to it.

Outdoor Enthalpy Changeover -- For enthalpy control, accesso U enthalpy sensor (p_u-t number HH57AC078)
is lequired.
Replace the standard outdoor d U bulb temperature sensor with
the accesso U enthalpy sensor in the same mounting location.
When the outdoor air enthalpy rises above the outdoor enth_dpy
changeover set point, the outdoor-tilt dmnper moves to its minimum position. The outdoor enth_dpy changeover set point is set
with the outdoor enthalpy set point potentiometer
on the
EconoMiSer [V controller The set points are A, B, C, and D.
See Fig. 27. The factou-installed
620-ohm jumper must be in

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

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. 28. 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 unnecessary fan overload.
T R = Return-Air Temperature
RA = Percent of Return Air
T M = Mixed-Air
As tin example, if local codes require 10% outdoor
dunng occupied conditions, outdoor-air temperature

When using demand ventilation, the minimum damper position represents the minimum ventilation position for VOC (volatile organic compounds) ventilation requirements. The maximum
demand ventilation position is used for lhlly 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.

Thermostats
-- Tile EconoMi$er IV control woNs with conventional thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), WI (heat stage 1), W2 (heat stage 2), trod G (fan). The
EconoMi$er
IV control does not support space temperature

box.
rate of 5% and an output of 6.7 volts provides the maximum
ventilation rate of 20% (or base plus 15 cfm per pelion). Use
Fig. 29 to determine the maximum setting of the CO 2 sensol:
For example, a 1100 ppm set point relates to a 15 cfm per
person design. Use the 1100 ppm curve on Fig. 29 to find the
point when the CO 2 sensor output will be 6.7 volts. Line up the
point on the giaph with the left side of the chart to determine
that the range configuration for the CO 2 sensor should be 1800
ppm. The EconoMiSer IV controller will output the 6.7 volts
from the CO 2 sensor to the actuator when the CO 2 concentration in the space is fit 1100 ppm. The DCV set point may be left
fit 2 volts since the CO 2 sensor voltage will be ignored by the
EconoMiSer
IV controller until it rises above the 3.6 volt
setting of the minimum position potentiometel:
Occupancy Control -- The factory default configuration for
the EconoMiSer IV control is occupied mode. Occupied status
is provided by the black jumper from termimfl TR to termintfl
N. When unoccupied mode is desired, install a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 26. When the timeclock contacts ale closed, the
EconoMi$er IV control will be in occupied mode. When the
timeclock contacts are open 0emoving
the 24-v signtfl from
terminal N), the EconoMiSer IV will be in unoccupied mode.
Once the fully occupied dmnper position has been determined, set the maximum dmnper demand control ventilation
potentiometer
to this position. Do not set to the maximum
position as this can result in over-ventilation to the space and
potential high-humidity levels.
Demand Control Ventilation
-- When using the EconoMiSer IV for demand control ventilation, there 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 &lmper position must be calculated
to provide the desired fresh ail:
CO_2 Sensor Configuration
-- The CO2 sensor has preset
standard voltage settings that can be selected anytime after the
sensor is powered up. See Table 29.
Use setting 1 or 2 for Carrier equipment. See Table 29.
1. Press Clear and Mode buttons. Hold fit least 5 seconds
until the sensor enters the Edit mode.
Typictflly the maximum ventilation rate will be about 5 to
10% more than the typical cfm required per person, using normal outside air design criteria.
A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied
occupancy, trod equipment that cannot exceed the required
ventilation rate fit design conditions. Exceeding the required
ventilation rote means the equipment can condition air at a
maximum ventilation rate that is greater than the required
ventilation rate for maximum
occupancy.
A proportionalanticipatory
strategy will cause the fresh air supplied to
increase as the room CO 2 level increases even though the CO 2
set point has not been reached. By the time the CO 2 level
reaches the set point, the damper will be fit maximum ventilation and should maintain the set point.
In order to have the CO_ sensor control the economizer
dmnper in this manner, firs[ determine the &unper voltage
output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contaminants
during unoccupied periods. The following equation may be used to determine
the percent of outside-air entering the building for a given
dmnper position. For best results there should be fit least a
10 degree difference in outside and return-air temperatures.

Dehumidification
of Fresh Air with DCV Control -- Information from ASHRAE
(American
Society
of Heating,
Refrigeration, and Air Conditioning Engineers) indicates that
the largest humidity load on tiny zone is the fresh air introducedi For some applications, a device such as a 62AQ energy
recovery unit is added to reduce the moisture content of the
fresh air being brought into the building when the enthalpy is
high. In most cases, the normal heating and cooling processes
are more than adequate to remove the humidity loads for most
commercM applications.

Once base ventilation has been detemfined, set the minimum dmnper position potentiometer to the correct position.

and/or a dehumidification
option should be considered.

-- When
the thermostat calls for one stage of cooling, YI and G are energized. The indoor-fan contactor (IFC) and compressor contactor(s) (C.AI and C.BI on three-compressor

only on two-compressor
units), and outdoor-fan
contactors
(OFCI and OFC2 when outdoor temperature is above LTS setting) ale energized and the indoor-fan motol: compressor(s)
(AI and BI on three compressor units or AI only on twocompressor units), and outdoor fans controlled by OFCI are
stalled. If the outdoor temperature is above the setting of the
low temperature switch, the outdoor fans controlled by OFC2
are _dso stmted.
When additional heat is required, W2 closes and initiates
power to the second stage of the main gas valve. When the
thermostat is satisfied, WI and W2 open and the gas valve
closes, interrupting the flow of gas to the main burners. If the
call forWl lasted less than 1 minute, the heating cycle will not
terminate until 1 minute after WI became active. If the unit is
controlled through a room thermostat set for fan auto., the
indoor-fan motor will continue to operate for an additional
45 seconds then stop (and the outdoor-air dampers will close).
If the overtemperatme
limit opens after the indoor motor is
stopped within 10 minutes of WI becoming inactive, on the
next cycle the time will be extended by 15 seconds. The
maximum delay is 3 minutes. Once modified, the fan off delay
will not change back to 45 seconds unless power is reset to
the control.
If more cooling is required, the thermostat will call for a
second stage of cooling, energizing Y2. This will allow relay
CRI to energize, which in turn energizes the compressor
contactor
(C.CI

IV -- When free
cooling is not available, the compressors 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 dampers will be modulated (open or close) to
bring the supply-air temperature
back within the set point
limits.
ECONOMIZER
NOTE: The 48HJ020-028 units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W
on the [GC (integrated gas unit controller) board. An LED
(light-emitting diode) on the IGC bo_ud will be on during normal operation. A check is made to ensure that the rollout
switch and limit switch are closed and the induced-draft motor
is running. The induced-draft
motor is then energized, and
when speed is proven with the hall effect sensor on the motor.
the ignition activation period begins. The burners will ignite
within 5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out.
To reset the control, break 24-v power to the thermostat.
For EconoMi$er
IV operation, there must be a thermostat
call for the fan (G). This will move the &{mper to its minimum
position during the occupied mode.
Above 50 F supply-air temperature, the dampers will modulate from 100% open to the minimum open position. From 50 F
to 45 F supply-tdr temperature, the dampers will maintain at
the minimum open position. Below 45 F the &tmpers will be
completely shut. As the supply-air temperature rises, the &{topers will come back open to the minimum open position once
the supply air temperature rises to 48 E
When ignition occurs the IGC board will continue to monitor the condition of the rollout and limit switches, the hall effect

IV -- When the
room temperature calls for heat, file heating controls am ene>
gized as described in the Heating, Units Without Economizer
section. The IFM (indoor fan motor) is energized and the
EconoMiSer IV damper modulates to the minimum position.
When the thermostat is satisfied and WI and W2 ale deenergized, the IFM continues to run, and file economizer damper
modulates to the minimum position.
MAIN BURNER -- At file beginning of each heating season,
inspect for deterioration or blockage due to corrosion or other
causes. Observe the main burner flames. Refer to Main Burners section on page 48.
FLUE GAS PASSAGEWAYS
-- Tile flue collector box and
heat exchanger
cells may be inspected by removing heat
section access panel (Fig. 4), flue box cover, and main burner
assembly (Fig. 30). Refer to Main Burners section on page 48
for burner removed sequence. If cleaning is required, clean
tubes with a wire brush.
Use c_mtion with ceramic heat exchanger baffles. When installing retaining clip, be sure file center leg of the clip extends
inward toward baffle. See Fig. 31.

To inspect blower wheel, remove heat section panel. Using
an inspection mirror and flashlight, look into the flue exhaust
duct to inspect file wheel. If cleaning is required, remove motor

box cover to the flue box. See Fig. 30. Remove the screws
holding the inducer housing to the inlet plate. The wheel can
then be removed fiom the motor shaft and cleaned with a detergent or solvent. Replace the wheel onto the motor shaft in the
correct position and reassemble the flue cover onto the flue
box.
Lubrication
COMPRESSORSEach compressor is chguged with the
correct amount of oil al the factory. Conventional white oil
(Zerol 150T or Sontex SA32) is used. White oil is compatible
wifll 3GS oil, and 3GS oil may be used if the addition of oil is
required. See compressor nameplate for original oil charge. Oil
mchguge amount is shown in Table 1. When a compressor is
exchanged in the field it is possible that a major portion of the
oil fiom the replaced compressor may still be in the system.
While this will not affect the reliability of the replacement
compressor, tile extra oil will add rotor drag and increase power usage. To lemove this excess oil, an access valve may be
added to the lower portion of the suction line at the inlet of the
compmssoc The compressor should then be run for 10 minutes, shut down and the access valve opened until no oil flows.
This should be repeated twice to make sure the proper oil level
has been achieved.
SERVICE
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
Cleaning -- Inspect unit interior at beginning of each heating and cooling season and as operating conditions require. Remove unit top panel and/or side panels for access to unit interiol:
EVAPORATOR COIL -- Clean as required with commerci_d
coil cleanel:
CONDENSER COIL--Clean
condenser coil annu_dly and
as required by location and outdoo>air conditions. Inspect coil
monflfly; clean as required.
FAN SHAFT BEARINGS -- Lubricate bearings at least evely 6 months with suitable bearing grease. Typical lubricants
are given below:
CONDENSATE DRAIN -- Check and clean each year at the
st_u'tof the cooling season. In winter, keep drains and traps dry.
An access panel is located above the condensate connection to
allow easy clean out of the condensate pan. Tile first time the
panel is removed, file insulation behind the access panel will
need to be cut away. Carefully cut file insulation with a knife or
blade on three sides so the insulation can be folded out of the
way during cleaning. Be careful not to damage components behind the insulation while cutting. Once cleaning is completed,
fold the insulation back into place and secure the access panel
in the original position.
FILTERS -- Clean or replace at stalt of each heating and cooling season, or more often if operating conditions require. Refer
to Table 1 for type and size.
OUTDOOR-AIR INLET SCREENS -- Clean screens with
steam or hot water and a mild detergent. Do not use throwaway
filters in place of screens. See Table 1 for quantity and size.

modifications or additions must be in compliance with all applicable codes.
2. Use 75 C minimum wire for field power supply. Use copper wires for all units.
3. All circuit breakers "Must Trip Amps" are equal to or less than 156% RLA
(rated load amps).
4. Compressor and fan motors are thermally protected. Three-phase motors
protected against primary single phase conditions.
5. The CLO locks out the compressor to prevent short cycling on compressor
overload and safety devices; before replacing CLO, check these devices.
