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 safety precautions in litera-
ture, tags, and labels attached 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 the National Electrical Cede
(NEC) for special installation requirements.

GENERAL

These instructions cover the installation, start-up and

service of cooling only and heat pump duct-free systems.

INSTALLATION

Step 1 -- Complete Pre-lnstallation Checks

UNPACK UNITS (See Fig. l) -- Move the unit to final
location. Remove units from carton, being carefld not to

damage service valves and grilles. See Tables 1A and IB for
installation materials included in shipment_

Before installing or servicing system, always turn off main
power to system. Them may be more than one disconnect

switch. Turn off accessory heater power ffapplicable. Elec-
trical shock can cause serious personal injury.

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 2-3B.

See Fig. 2 for unit dimensions. Allow sui%cient space for

airflow clearance, wiring, refrigerant piping, and servicing
units. See Fig. 3.

Locate outdoor units so that condenser airflow is unrestrict-

ed on both sides. Refer to Fig. 3.
Outdoor Units (38HDV, QRV) -- Unit may be mounted on a

level pad directly on base legs or mounted on raised pads at
support points.

Avoid mounting die unit in areas that are too close to heat

radiation, vapor or flammable gas, or in dusty areas.
Indoor Units (40QNC,QNQ) -- Avoid mounting the unit in

areas that are:

• exposed to direct sunlight

• too close to heat sources

• too close to humid conditions

• located in an area with oily ambient conditions.
