INSTALLATION
Step 1 — Complete Pre-Installation Checks
UNPACK UNIT (See Fig. 1) — Move the unit to final loca-
tion. The grille panel and the remote control are separately
packed for maximum protection. Remove unit from carton, be-
ing careful not to lift the unit by the condensate drain discharge
pipe or by the refrigerant connections. Handle by the four
corners of the unit. See Table 1 for field-supplied materials
required for installation.
INSPECT SHIPMENT — File a claim with the shipping
company if shipment is damaged or incomplete. Check the unit
nameplates to ensure units match job requirements.
CONSIDER SYSTEM REQUIREMENTS — Consult local
building codes and NEC for special installation requirements.
Use only designated indoor units with outdoor units. See
Tables 2-4B.
See Fig. 2 for unit dimensions. Allow sufficient space for
airflow clearance, wiring, refrigerant piping, and servicing
units.
Avoid mounting the unit in areas that are:
• exposed to direct sunlight
• too close to heat sources
• damp or areas exposed to water
• located in areas that could obstruct air circulation, such
as near curtains or furniture
