SAFETY CONSIDERATIONS
Installation and servicine of air-conditioning equipment
can be hazardous due to system pressure and electrical com-
ponents. Only trained and qualified service personnel should
install, repair. or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service per-
sonnel. When working on air-conditioning equipment, ob-
serve 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 ex-
tinguishers available for all brazing operations.
A WARNING
Before performing service or maintenance operations on
unit. turn off main power switch to unit. Electrical shock
could cause personal injury.
Disconnect gas piping from unit when leak
testing at pressure greater than ' : psig. Pres-
sures greater than 1 , psig will cause gas valve
damage resulting in hazardous condition. If
gas valve is subjected to pressure greater than
l 2 psig, it must be replaced before use. When
pressure testing field -supplied gas piping at
• • pressures Of' 2 psig or less, a unit connected
to such piping must be isolated by manually
closing the gas valve(s).
INSTALLATION
Unit is shipped in the vertical discharge configuration. To
convert to horizontal discharge application, remove duct open-
ing covers. Using the same screws, install covers on duct
openings in basepan of unit with insulation -side down. Seals
around openings must be tight.
NOTE: Any combination of supply and return ducting is per-
missible, i.e., vertical supply combined with horizontal
return.
Step 1 — Provide Unit Support
ROOF CURB — Assemble and install accessory roof curb
in accordance with instructions shipped with curb. See Fig. 1.
Install insulation, cant strips, roofing felt, and counter flash-
ing as shown. Ductwork must be attached to curb, not to the
unit. If electric or control power is to be routed through the
basepan, attach the accessory thru-the-bottom service con-
nections to the basepan in accordance with the accessory in-
stallation instructions. Connections must be installed before
unit can be set on roof curb.
IMPORTANT: The gasketing of the unit to the roof
curb is critical for a watertight seal. Install gasket sup-
plied with the roof curb as shown in Fig. 1. Improp-
erly applied gasket can result in air leaks and poor unit
performance.
Curb should be level. Unit leveling tolerances are shown
in Fig. 2. This is necessary for unit drain to function prop-
erly. 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 unit
cabinet. Install a gravel apron in front of condenser -coil air
inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Step 2 — Field Fabricate Ductwork — Secure all
ducts to roof curb and building structure on vertical dis-
charge units. Do not connect ductwork to unit. For horizon-
tal applications, field -supplied flanges should be attached to
horizontal discharge openings and all ductwork should be
secured to the flanges. Insulate and weatherproof all exter-
nal ductwork, joints, and roof openings with counter flash-
ing 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, the return
should be ducted through the roof deck to comply with ap-
plicable fire codes.
A minimum clearance is not required around ductwork.
Cabinet return -air static shall not exceed —.35 in. wg with
Durablade economizer, .20 in. wg with Parablade econo-
mizer. or .45 in. wg without economizer.
These units are designed for a minimum continuous return -
air temperature in heating of 50 F (dry bulb) or an intermit-
tent operation down to 45 F (dry bulb), such as when used
with a night setback thermostat.
Step 3 — Install External Trap for Condensate
Drain — The unit's Ih in. 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 hori-
zontal applications.
When usin; the standard side drain 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 in-
stallation, relocate the factory -installed plug from the bot-
tom connection to the side connection. See Fig. 3. The pip-
in- for the condensate drain and external trap can be completed
after the unit is in place.
All units must have an external trap for condensate drain-
age. Install a trap at least 4 -in. deep and protect against freeze-
up. See Fig. 4. If drain line is installed downstream from the
external trap, pitch the line away from the unit at 1 in. per
10 ft of run. Do not use a pipe size smaller than the unit
connection.
Step 4 — Rig and Place Unit — Inspect unit for
transportation damage, and file any claim with transpor-
tation agency. Keep unit upright and do not drop. Spreader
bars are not required if top crating is left on unit, and rollers
may be used to move unit across a roof. Level by using unit
frame as a reference. See Table I and Fig. 5 for additional
information. Operating weight is shown in Table I and
Fig. 5.
Lifting holes are provided in base rails as shown in
Fig. 6. Refer to rigging instructions on unit.

rCAUTION
All panels must be in place when rigging.
POSITIONING — Maintain clearance around and above unit
to provide minimum distance from combustible materials.
proper airflow, and service access. See Fig. 6. A properly
positioned unit will have the following clearances between
unit and roof curb: ' .-in. clearance between roof curb and
base rails on each side and front of unit; 15 32 -in. clearance
between roof curb and rear of unit. (See Fig. 1, section C -C.)
Do not install unit in an indoor location. Do not locate
unit air inlets near exhaust vents or other sources of con-
taminated air.
Be sure that unit is installed such that snow will not block
the combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class
A, B, or C roof -covering material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Locate mechanical draft system flue assembly at least
48 in. from any opening through which combustion prod-
ucts could enter the building, and at least 48 in. from an ad-
jacent building. When unit is located adjacent to public
walkways, flue assembly must be at least 7 ft above grade.
NOTE: When unit is equipped with an accessory flue dis-
charge deflector, allowable clearance is 18 inches.

Flue gas can deteriorate building materials. Orient unit such
that flue gas will not affect building materials.
Adequate combustion -air space must be provided for proper
operation of this equipment. Be sure that installation com-
plies with all local codes and Section 5.3, Air for Combus-
tion and Ventilation. NFGC (National Fuel Gas Code), ANSI
(American National Standards Institute) Z223.1-1984 and ad-
dendum Z223. I a-1987. In Canada, installation must be in
accordance with the CAN 1.B 149.1 and CAN l .B 149.2 in-
stallation codes for gas burning appliances.
Flue vent discharge must have a minimum horizontal clear-
ance of 4 ft from electric and gas meters, gas regulators, and
gas relief equipment.
After unit is in position, remove shipping materials and
risnaing skids.
Step 5 — Install Flue Hood — Flue hood is shipped
screwed to the burner compartment access panel. Remove
from shipping location and. using screws provided, install
flue hood in location shown in Fig. 6 and 7.
Step 6 — Install Gas Piping — Unit is equipped for
use with type of gas shown on nameplate. Refer to local build -
in; codes, or in the absence of local codes, to ANSI Z223.1-
1984 and addendum Z223- I A-1987 entitled National Fuel
Gas Code. In Canada. installation must be in accordance with
the CAN LB 149.1 and CAN LB 149.2 installation codes for
:as burning appliances.
For natural gas applications. the gas pressure at unit gas
connection must not be less than 4 in. wg or greater than
13 in. wg, while the unit is operating. On 48HJ005-007 high -
heat units, the eas pressure at unit gas connection must not
be less than 5 in. w; or greater than 13 in. wg while the unit
is operating. For propane applications, the gas pressure must
not be less than 5 in. wg or greater than 13 in. wg at the unit
connection.
Size gas supply piping for 0.5 in. wg maximum pressure
drop. Do not use supply pipe smaller than unit gas
connection.
Support gas piping as shown in the table in Fig. 8. For
example, a'/. -in. gas pipe must have one field -fabricated sup-
port beam every 8 ft. Therefore, an 18 -ft long gas pipe would
have a minimum of 2 support beams, and a 48 -ft long pipe
would have a minimum of 6 support beams.
See Fig. 8 for typical pipe guide and locations of external
manual gas shutoff valve.
Step 7 — Make Electrical Connections
Unit cabinet must have an uninterrupted, unbroken elec-
trical ground to minimize the possibility of personal in-
jury 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 elec-
trical ground when installed in accordance with NEC
(National Electrical Code) ANSI/NFPA (National Fire
Protection Association), latest edition, and local elec-
trical codes. Do not use gas piping as an electrical ground
Failure to follow this warning could result in the in-
staller being liable for personal injury of others.
FIELD POWER SUPPLY—All units except 208230-v units
are factory wired for the voltage shown on the nameplate. If
the 208230-v unit is to be connected to a 208-v power
supply, the transformer must be rewired by moving the black
wire from the 230-v orange wire on the transformer and con-
necting it to the 200-v red wire from the transformer. The
end of the orange wire must then be insulated.
Refer to unit label diagram for additional information. Pig-
tails are provided for field service. Use UL (Underwriters'
Laboratories) approved copper/aluminum connector.
When installing units, provide a disconnect per NEC.

Fig. 8 — Gas Piping Guide (With Accessory
Thru-the-Curb Service Connections)
All field wiring must comply with NEC and local
requirements.
Install conduit through side panel openings indicated in
Fig. 6. Route power lines through connector to terminal con-
nections as shown in Fig. 9.
Voltage to compressor terminals during operation must be
within volta_e range indicated on unit nameplate (also see
Tables 2A and 26). On 3-phase units, voltages between phases
must be balanced within 2% and the current within 10%.
Use the formula shown in Tables 2A and 2B. Note 2 to de-
termine the percent voltage imbalance. Operation on im-
proper line voltage or excessive phase imbalance constitutes
abuse and may cause damage to electrical components. Such
operation would invalidate any applicable Carrier warranty.
NOTE: If accessory thru-the-bottom connections and roof
curb are used. refer to the Thru-the-Bottom Accessory In-
stallation Instructions for information on power wiring. The
power wiring will be routed through a field -drilled hole in
the basepan. The basepan is specially designed and dimpled
for drilling the power access connection holes.
FIELD CONTROL WIRING — Install a Carrier -approved
accessory thermostat assembly according to installation in-
structions included with the accessory. Locate thermostat as-
sembly on a solid wall in the conditioned space to sense av-
erage temperature in accordance with thermostat installation
instructions.
Route thermostat cable or equivalent single leads of col-
ored wire from subbase terminals through connector on unit
to low -voltage connections (shown in Fig. 10).
Connect thermostat wires to matching screw terminals of
low -voltage connection board. See Fig. 10.
NOTE: For wire runs up 50 ft, use no. 18 AWG (American
Wire Gage) insulated wire (35 C minimum). For 50 to
75 ft, use no. 16 AWG insulated wire (35 C minimum). For
over 75 feet, use no. 14 AWG insulated wire (35 C mini-
mum). All wire larger than no. 18 AWG cannot be
directly connected to the thermostat and will require a junc-
tion box and splice at the thermostat.
Pass the control wires through the hole provided in the
corner post; then feed wires through the raceway built into
the corner post to the 24-v barrier located on the left side of
the control box. See Fig. 11. The raceway provides the UL
required clearance between high- and low -voltage wiring.
HEAT ANTICIPATOR SETTINGS — Set heat anticipator
settings at .14 amp for the first stage and .14 for second stage
heating, when available.
Step 8 — Adjust Factory -Installed Options
MOISTUREMISER DEHUMIDIFICATION PACKAGE —
MoistureMiser package operation can be controlled by field
installation of a Carrier -approved humidistat (Fig. 12). To
install the humidistat:
1. Route humidistat cable through hole provided in unit cor-
ner post.
2. Feed wires through the raceway built into the corner post
to the 24-v barrier located on the left side of the control
box. See Fig. 11. The raceway provides the UL -required
clearance between high- and low -voltage wiring.
3. Use a wire nut to connect humidistat cable into low -
voltage wiring as shown in Fig. 13.
APOLLO CONTROL—The optional Apollo Control is used
to actively monitor all modes of operation as well as indoor
fan status, filter status, and indoor -air quality. The Apollo
Control is designed to work with Carrier TEMP and VVTI;
systems.
The thermostat must be wired to the Apollo Control be-
fore starting the unit. Refer to the Apollo Control installa-
tion instructions for information on installing the thermostat.
DISCONNECT SWITCH — The optional disconnect switch
is non-fused. The switch has the capability of being locked
in place for safety purposes.

' breaker. UL Canada units may be fuse or circuit breaker.
2. Unbalanced 3 -Phase Supply Voltage
Never operate a motor where a phase imbalance in supply volt-
age is greater than 2%. Use the following formula to determine
' the percent voltage imbalance.
= 100 x max voltage deviation from average voltage

Example: Supply voltage is 460-3-60.
AB = 452 v

AC = 455 v
Average Voltage
452 + 464 + 455
=

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 voltage imbalance.
% Vottage Imbalance = 100 x 457
= 1.53%
This amount of phase imbalance is satisfactory as 4 is below the
maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more
than 2%, contact your local electric utility company
immediately.

' d. After installation is complete, calculate the mini-
mum airflow across the economizer. To calculate the
minimum airflow, the following data is needed: total
cfm (cfm3), temperature of the total cfm (T3), tem-
perature of the return air (T,), and temperature of the
entering outdoor air (T,). Cfrl, is the outdoor air (mini-
mum) cfm.,
13
Insert the data into the following equations:
T, (cfm') + T, (cfm_) =
T3
cfm3
cfm: = (cf n3 cfm,)
Therefore:
T, (cfm,) + TZ (cfm3 cfm,) = T3
3
Further derivation reveals the following formula for
airflow:
cfin,
(T3 Tz) cftn,
_
(Tl T2)
Use this equation to determine cft-q, which is the mini-
mum airflow across the economizer.
If cfm, does not match the desired minimum airflow
from Step 1, re -adjust the minimum position setting
screw.
7. Determine the enthalpy changeover set point from
Fig. 25. The enthalpy changeover set point should be
set to return the outdoor -air damper to the minimum po-
sition when enthalpy rises above the set point. The set-
tings are A, B, C, and D. Set the enthalpy changeover
per the setting in Fig. 25.
8. Replace outdoor -air opening panel using screws from
Step 2. Replace filter access panel. Ensure the filter ac-
cess panel slides along the tracks and is securely
engaged. See Fig. 26.
9. Fasten hood top and side plate assembly (Fig. 27) to
outdoor -air opening panel with screws provided.
10. Slide outdoor -air inlet screen into screen track on hood
side plate. While holding screen in place, fasten screen
retainer to hood using screws provided. See Fig. 28.

1. Boldface indicates field -supplied drive is required. (See Note 3.)
2. = indicates field -supplied motor and drive required.
3. Motor drive range is 840 to 1185 rpm. All other rpms require a field -supplied drive.
4. Values include losses for filters, unit casing, and wet coils.
5. Maximum continuous bhp is 1.20. Extensive motor and electrical testing on these units ensure that the full
range of the motor can be utilized with confidence. Using your fan motors up to the ratings shown will not
result in nuisance tripping or premature motor failure. Unit warranty will not be affected.
6. Use of a field -supplied motor may affect wire sizing. Contact your Carrier representative to verify.
7. Interpolation is permissible. Do not extrapolate.

PRE -START-UP
Failure to observe the following warnings could result
in serious personal injury:
1. Follow recognized safety practices and wear protec-
tive goggles when checking or servicing refrigerant
system.
2. Do not operate compressor or provide any electric
power to unit unless compressor terminal cover is in
place and secured.
3. Do not remove compressor terminal cover until all
electrical sources are disconnected.
4. Relieve all pressure from system before touching or
disturbing anything inside terminal box if refrigerant
leak is suspected around compressor terminals.
5. Never attempt to repair soldered connection while re-
frigerant system is under pressure.
6. Do not use torch to remove any component. System
contains oil and refrigerant under pressure. To re-
move a component, wear protective goggles and pro-
ceed as follows:
a. Shut off electrical power and then gas to unit.
b. Reclaim refrigerant to relieve all pressure from
system using both high- and low-pressure ports.
C. Cut component connection tubing -with tubing cut-
ter and remove component from unit.
d. Carefully unsweat remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
Proceed as follows to inspect and prepare the unit for ini-
tial start-up:
I. Remove all access panels.
2. Read and follow instructions on all WARNING, CAU-
TION, and INFORMATION labels attached to, or
shipped with, unit.
3. Make the following inspections:
a. Inspect for shipping and handling damages such as bro-
ken lines, loose parts, disconnected wires, etc.
b. Inspect for oil at all refrigerant tubing connections and
on unit base. Detecting oil generally indicates a re-
frigerant leak. Leak -test all refrigerant tubing connec-
tions using electronic leak detector, halide torch, or
liquid -soap solution.
c. Inspect all field- and factory -wiring connections. Be
sure that connections are completed and tight.

START-UP
Unit Preparation - Make sure that unit has been
installed in accordance with installation instructions and
applicable codes.
Return -Air Filters - Make sure correct filters are
installed in unit (see Table 1). Do not operate unit without
return -air filters.
Outdoor -Air Inlet Screen - Outdoor -air inlet screen
must be in place before operating unit.
Compressor Mounting - Compressors are inter-
nally spring mounted. Do not loosen or remove compressor
holddown bolts.
Internal Wiring - Check all electrical connections in
unit control boxes. Tighten as required.
Refrigerant Service Ports - Each unit system has
3 Schrader type service ports: one on the suction line, one
on the liquid line, and one on the compressor discharge line.
Be sure that caps on the ports are tight. Two additional Schrader
valves are located under the high-pressure and low-pressure
switches, respectively.
Compressor Rotation - On 3-phase units with scroll
compressors, it is important to be certain compressor is
rotating in the proper direction.. To determine whether or not
compressor is rotating in the proper direction:
1. Connect service gages to suction and discharge pressure
fittings.
Energize the compressor.
3. The suction pressure should drop and the discharge pres-
sure should rise, as is normal on any start-up.
If the suction pressure does not drop and the discharge
pressure does not rise to normal levels:
1. Note that the evaporator fan (006 and 007 only) is prob-
ably also rotating in the wrong direction.
2. Tum off power to the unit.
3. Reverse any two of the unit power leads.
d. Inspect coil fins. If damaged during shipping and han- 4. Reapply power to the compressor.
dling, carefully straighten fins with a fin comb. The suction and discharge pressure levels should now move
4. Verify the following conditions: to their normal start-up levels.
a. Make sure that condenser -fan blade is correctly NOTE: When the compressor is rotating in the wrong
positioned in fan orifice. Refer to Condenser -Fan Ad- direction, the unit will make an elevated level of noise and
justment section on page 25 for more details. will not provide cooling.
