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 may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for unbrazing operations. Have fire extinguisher
available for all brazing operations.
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.
!WARNING
NOTE: Ensure that the voltage listed on the unit information
plate agrees with the electrical supply to the unit.
INSTALLATION
Unit is shipped in the vertical discharge configuration. To convert
to horizontal configuration, remove horizontal duct opening
covers. Using the same screws, install covers on duct openings in
basepan of unit with the insulation-side down. Seals around duct
openings must be tight.
STEP 1 —PROVIDE UNIT SUPPORT
ROOF CURB
Assemble and install the accessory roof curb in accordance with
the instructions shipped with the curb. (See Fig. 1.) Install
insulation, cant strips, roofing felt, and counter flashing as shown.
Ductwork must be attached to the curb, not to the unit. If electric
or control power will be routed through the basepan, attach the
accessory thru-the-bottom service connections to the basepan and
roof curb in accordance with the accessory installation
instructions. Install connections before the unit is set on the roof
curb.
IMPORTANT: The gasketing of the unit to the roof curb is critical
for water--tightness. Install the gasket supplied with the roof curb as
showninFig.1.Animproperlyappliedgasketcanalsoresultinair
leaks and poor unit performance.
The roof curb should be level to ensure that the unit drain
functions properly. Unit leveling tolerances are shown in Fig. 2.

Fig. 2 --- Unit Leveling Tolerances
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 the unit cabinet. Install a gravel apron in front of the
condenser coil air inlet to prevent grass and foliage from
obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb, if
required.
ALTERNATE UNIT SUPPORT
When the curb or adapter cannot be used, support unit with
sleepers using unit curb or adapter support area. If sleepers 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 —FIELD--FABRICATED DUCTWORK
Secure all ducts to the roof curb and building structure on vertical
discharge units. Do not connect ductwork to the unit. For
horizontal applications, attach field-supplied flanges to the
horizontal discharge openings and attach all ductwork 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, duct the return
through the roof deck to comply with applicable fire codes.
A minimum clearance is not required around ductwork. Cabinet
return-air static pressure (a negative condition) should not exceed
0.35 in. wg with economizer, or 0.45 in. wg without economizer.
STEP 3 —INSTALL CONDENSATE DRAIN LINE
AND EXTERNAL TRAP
Condensate drain connections are located at 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 discharge units.
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. The center drain plug looks
like a star connection, but can be removed with a 1/2-in. socket
drive extension. (See Fig. 3.) Complete the piping for the
condensate drain and external trap 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 it against freeze-up. If
drain line is installed downstream from the external trap, pitch the
line away from the 50HJQ unit at 1/4in. per ft of run. Do not use
a pipe size smaller than the unit connection (3/4-in.). (See Fig. 4.)

STEP 4 —RIG AND PLACE UNIT
Inspect the unit for transportation damage, and file any claim with
the transportation agency. Keep the unit upright and do not drop.
Spreader bars are not required if top crating is left on the unit, and
rollers may be used to move the unit across a roof. Level by using
the unit frame as a reference. See Table 1 and 2 and Fig. 5 for
additional information. Operating weight is shown in Table 1 and
2 and Fig. 5.
Lifting holes are provided in the base rails as shown in Fig. 5 and
6. Refer to rigging instructions on the unit.

Fig. 5 --- Rigging Details
All panels must be in place when rigging. Unit is not designed
for handling by fork truck. Damage to unit may result.
CAUTION
!
POSITIONING
A properly positioned unit will have the following
clearances: 1/4-in. clearance between the roof curb and the base
rails on each side and duct end of the unit; 1/4-in. clearance
between the roof curb and the condenser end of the unit. (See Fig.
1, section C-C.)
Do not install the unit in an indoor location. Do not locate the
unit air inlets near exhaust vents or other sources of contaminated
air.
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 top crating.

STEP 5 —MAKE ELECTRICAL CONNECTIONS
Failure to follow this warning could result in the installer
being liable for personal injury of others.
Unit cabinet must have an uninterrupted, unbroken
electrical ground to minimize the possibility of personal
injury if an electrical fault should occur. This ground may
consist of electrical wire connected to unit ground lug in
control compartment, or conduit approved for electrical
ground when installed in accordance with NEC (National
Electrical Code), ANSI/NFPA (American National
Standards Institute/National Fire Protection Association)
70 (latest year), and local electrical codes.
!WARNING
FIELD POWER SUPPLY
All units (except 208/230-v units) are factory wired for the
voltage shown on the 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 1/4-in.
male spade terminal on the transformer and connecting it to the
208-v 1/4-in. male spade terminal from the transformer. Refer to
the unit label diagram for additional information. Pigtails are
provided for field wire connections. Use factory-supplied splices
or a UL (Underwriters’ Laboratories) approved copper/aluminum
connector.
When installing units, provide a disconnect per the NEC. All field
wiring must comply with the NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through the side panel openings. For units
without electric heat, install conduit between the
disconnect and control box.
2. Install power lines to the terminal connections as shown in
Fig. 7.
3. For units with electric heat, refer to Table 3 and Accessory
Electric Heat Installation Instructions.
During operation, voltage to compressor terminals must be within
the range indicated on the unit nameplate (also see Tables 4A-4D
and 5A--5D). On 3-phase units, voltages between phases must be
balanced within 2% and the current within 10%. Use the formula
shown in Tables 4A-4D and 5A--5D, Note 2, 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
invalidates any applicable Carrier warranty.
NOTE: If the unit is mounted on a roof curb and electrical
power will be run up “thru-the-bottom,” be sure to use the proper
connection kit listed in Fig. 1. This kit, available from your local
distributor, ensures a reliable watertight connection. Refer to the
thru-the-bottom accessory installation instructions for information
on wiring the unit.

*Two heater packages required to provide kW indicated.
** Minimum airflow is 350 cfm/ton (1400 cfm) when two CRHEATER004B00 heaters are installed on a 4 ton, 230v heat pump.
NOTES:
1. The rated heater voltage is 240 and 480 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 kWnew = 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
kWnew = 16 kW (215/240)2
kWnew = 12.8 kW (rating at 215 v)

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v.
If power distribution voltage to unit varies from rated heater voltage,
heater kW will vary accordingly.
†Heaters are field installed only.
**Fuse or HACR circuit breaker.
††Electrical disconnect cannot be used if electric heater is installed.
NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load equipment (refer to NEC Articles 430 and 440), the overcur-
rent protective device for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent-
age of voltage imbalance.
%VoltageImbalance
= 100 x max voltage deviation from average voltage
average voltage
Example: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage
=
452 + 464 + 455
3
=1371
3
=457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x 7
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maxi-
mum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more
than 2%,contact your local electric utility company immediately.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v.
If power distribution voltage to unit varies from rated heater voltage,
heater kW will vary accordingly.
†Heaters are field installed only.
**Fuse or HACR circuit breaker.
††Electrical disconnect cannot be used if electric heater is installed.
NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load equipment (refer to NEC Articles 430 and 440), the overcur-
rent protective device for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent-
age of voltage imbalance.
%VoltageImbalance
= 100 x max voltage deviation from average voltage
average voltage
Example: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage
=
452 + 464 + 455
3
=1371
3
=457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x 7
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maxi-
mum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more
than 2%,contact your local electric utility company immediately.
