SAFETY CONSIDERATIONS
Install and servicing air-conditioning equipment can be haz-
ardous due to system pressure and electrical components. Only
trained and qualified service personnel should install or serv-
ice air-conditioning equipment
Untrained personnel may 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 safety precautions 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 operations. Have a
fire extinguisher available. Read these instructions thor-
oughly. Consult local building codes and National Electrical
Code (NEC, U.S.A. Standard) for special installation
requirements.
Before installing or servicing system, always turn off
main power to system. There may be more than one dis-
connect switch. Turn off accessory heater power if
applicable. Electrical shock can cause personal injury.
Step 1 — Complete Pre-Installation Checks
UNPACK UNIT — Move unit to final location. Remove car-
ton from unit, being careful not to damage service valves or
grilles.
INSPECT SHIPMENT — File claim with shipping com-
pany if shipment is damaged or incomplete. Check unit name-
plate to ensure unit matches job requirements.
CONSIDER SYSTEM REQUIREMENTS — Consult
local building codes and NEC for special installation
requirements.
Allow sufficient space for airflow clearance, wiring,
refrigerant piping, and servicing unit. See Fig. 1 and 2. Unit
can be mounted on a level pad directly on base legs or
mounted on raised pads at support points. See Fig. 2 for cen-
ter of gravity.
