Installation and Start-Up Instructions
SAFETY CONSIDERATIONS
Installing and servicing air conditioning equipment
can be hazardous due to system pressure and electrical
components. Only trained and qualified service personnel
should install or service air conditioning equipment.
Untrained personnel can perform basic maintenance,
such as cleaning and replacing filters. All other operations
should be performed by trained service personnel. When
working on air conditioning equipment, observe pre
cautions in literature and on tags and labels attached
to unit.
Follow all safety codes. Wear safety glasses and
work gloves. Use quenching cloth for brazing opera
tions. Have fire extinguisher available. Read these
instructions thoroughly. Consult local building codes
and National Electrical Code (NEC) for special installa
tion requirements.

INSTALLATION
Step 1 — Check Equipment and Jobsite —
Install on a solid, level mounting pad. It is recommended
that unit be attached to pad using tiedown bolts. Fasten
unit to pad using holes provided in unit mounting feet.
See Fig. 1.
When installing, allow sufficient space for airflow
clearance, wiring, refrigerant piping and servicing. Main
tain a minimum of 4 ft clearance from obstructions above
and 18 in. on 3 sides of unit (12 in. on fourth side). Main
tain a distance of 24 in. between heat pumps. Position so
water or ice from roof or eaves cannot fall directly on unit.
Step 2 — Replace AccuRater™ Refrigerant
Control Piston in the indoor coil, if required, before
conneeting refrigerant lines. See AccuRater Selection
Charts, Table 2.
Step 3 — Make Piping Connections — Outdoor
units may be connected to indoor sections using Carrier
accessory tubing package (refer to Service data) or field-
supplied tubing of refrigerant grade, correct size and
condition (Table 1). For tubing requirements beyond
50 ft, obtain information from local Carrier distributor.
Outdoor units connected to Carrier-approved indoor
units contain correct system refrigerant charge for opera
tion with indoor unit of the same size when connected by
25 ft of field-supplied or Carrier aceessory tubing. Check
refrigerant charge for maximum efficiency (refer to
Table 5 and Service data).

Tighten nut until it bottoms on shoulder of fitting or
valve. Keep tube bottomed in Compatible Fitting
while tightening nut.
A CAUTION
If undersized, damaged or elliptically-shaped
tubing is used when making Compatible Fitting,
leaks may result.
DO NOT BURY MORE THAN 3 FT OF REFRIG
ERANT TUBING IN GROUND. If any section of
tubing is buried, there must be a 6-in. vertical rise to
valve connections on outdoor unit. If more than the
recommended length is buried, refrigerant may
migrate to cooler buried section during extended
periods of unit shutdown. This causes refrigerant
slugging and possibly compressor damage at start-up.
CONNECT REFRIGERANT LINES to fittings on out
door unit suction and liquid service valves (Fig. 1). Unit
Compatible Fittings permit mechanical (quick-connect)
or sweat connections.
Models 38OH042,048,060 — When using 1 -1 /8 in. fieldsupplied refrigerant suction line, sweat-connect suction
line to 1-1/8 in. end of required connection adapter. Be
sure to provide a heat sink at the service valve to prevent
damage during sweating operation. Connect 3/4-in. end
of adapter to unit suction line Compatible Fitting.
Connect liquid refrigerant line to unit. When a 7/8-in.
field-supplied suction line is used, provide a field-supplied
3/4-in. to 7/8-in. suction line adapter (not necessary if
38LS accessory tubing is used).
Mechanical Connection — Mate one set of connections at
a time.
1. Loosen nut on Compatible Fitting one turn. Do not
remove.
2. Remove plug and be sure O-ring is in the groove inside
the Compatible Fitting.
3. Cut tubing to correct length. Deburr and size as
necessary.
Sweat Connection— Use refrigerant grade tubing.
1. Remove locking nut, rubber O-ring and Schrader core
and cap from valve service port.
2. Cut tubing to correct length. Deburr and size as
necessary.
3. Insert tube in Compatible Fitting until it bottoms.
NOTE: Wrap top and bottom of service valves in wet
cloth to prevent damage by heat. Solder with lowtemperature 430 F silver alloy solder.
4. Replace Schrader core and cap.
5. Evacuate or purge system with field-supplied
refrigerant.

A WARNING
To avoid personal injury, be sure indoor blower has
stopped before attempting service or maintenance.
Heat Anticipator Settings for Room Thermo-
Stat(HH01AT171) — Set anticipator for room thermo
stat according to Table 4. These settings may be changed
slightly to provide a greater degree of comfort for a par
ticular installation.
Accessory Outdoor Thermostat provides adjust
able outdoor control of accessory electric heater. This
thermostat makes contact when a drop in outdoor tem
perature occurs. It energizes a stage of electric heat
when the outdoor temperature setting is reached, pro
vided the room thermostat is on the second stage of heat
ing. One outdoor thermostat is recommended for each
stage of electric heat after the first stage. Set the outdoor
thermostat(s) progressively lower for each stage. Refer
to heat load of building and unit capacity to determine
the correct outdoor thermostat settings.
The accessory supplemental heat relay is required when
2 outdoor thermostats are used. It is automatically ener
gized by the manually operated supplemental heat switch
in the indoor thermostat subbase. The thermostat locks
out compressor and the relay bypasses the outdoor
thermostats for electric heater operation during heat
pump shutdown. When one outdoor thermostat is used,
a supplemental heat relay is not required. The supple
mental heat switch in the indoor thermostat subbase
bypasses outdoor thermostat, locks out compressor and
activates electric heater.
MOUNT OUTDOOR THERMOSTAT in control box.
Attach brackets with short sheet metal screws to avoid
contact with coil. Leave capillary tube coiled in control
compartment making sure it is clear of all electrical con
nections and sharp metal edges.
MOUNT SUPPLEMENTAL HEAT RELAY in con
venient location on indoor unit. Attach with sheet metal
screw.
