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.
When working on air-conditioning equipment, observe pre-
cautions in literature and on tags and labels attached to unit.
NOTE: Ensure voltage listed on unit data plate agrees with
electrical supply to unit.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for brazing operations. Have fire
extinguisher available. Read these instructions thoroughly.
Consult local building codes and National Electrical Code
(NEC) (U.S.A. Standard) for special installation requirements.
INSTALLATION
The 38AK007, 008, and 012 units use hermetic compres-
sors. The 38AKS008, 009, and 012 units use semi-hermetic
compressors. See Table 1A or 1B for physical data.
Step 1 — Complete Pre-Installation Checks
UNCRATE UNIT (See Fig. 1) — Remove unit packaging
except for the top skid assembly and wood bumpers, which
should be left in place until after unit is rigged into place.

if shipment is damaged or incomplete.
Before installing or servicing system, always turn off main
power to system and install lockout tag on disconnect.
