SAFETY CONSIDERATIONS

Installation and servicing of air conditioning

equipment can be hazardous due to system pressure

and electrical components. Only trained and quali

fied service personnel should install, repair or serv

ice air conditioning equipment.

Untrained personnel can perform basic main

tenance functions of cleaning coils and cleaning

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 brazing oper

ations. Have fire extinguisher available for all braz

ing operations.

W.ARNING: Before performing scr\icc or

maintenance operations on sxstem. turn ofl

main powci switches to indoor unit and out

door unil. 1 urn ofl acccssoiA heater power

switch if applicable, riectrical shock could cause

personal itijur\.

INSTALLATION

Step 1 — Check Equipment and Jobsite

UNPACK UNIT — Move to final location. Lift

carton off, taking special care not to damage service

valves or grilles.

INSPECT EQUIPMENT — File claim with ship

ping company if shipment is damaged or incomplete.

COMPLETE OR CONSIDER SYSTEM RE

QUIREMENTS before installing the 38QF.

Consult local building codes and National

Electrical Code (NEC) for special installation

requirements.

When installing, allow sufficient space for air

flow clearance, wiring, refrigerant piping and serv

icing. Position so water or ice from roof cannot drop

directly on top of unit.

Make provisions for condensate drainage and

defrost water disposal whether unit is installed on

ground or roof. (Ensure unit basepan drainage holes

are not blocked.) See Step 2 for details. Roof in

stallation method for 38QF depends on building

construction and special requirements of local

codes. Be sure that roof can support unit weight.

It is recommended that 38QF units be used with

Carrier approved indoor sections; see Table 1.

System Refrigerant Control on 38QF units and

matching Carrier indoor units is a factory-installed

AccuRater™ device (bypass type). Bypass-type

AccuRater components are discussed in the service

section of this booklet. The AccuRater piston has a

refrigerant metering hole thru it and is field replace

able. Table 1 indicates indoor units for which the

required replacement piston is factory supplied with

specified 38QF outdoor unit. Replace piston as

described under AccuRater™ Servicing on page 13.
