WARNING

Installation or repairs made by unqualified

persons can result in hazards to you and others.

Installation MUST conform with local building

codes or, in the absence of local codes, with the

the National Electrical Code NFPA 70/ANSI

C1-1999 or current edition and Canadian

Electrical Code Part 1 CSA C.22.1.

The information contained in this manual is

intended for use by a qualified service technician

familiar with safety procedures and equipped

with the proper tools and test instruments.

Failure to carefully read and follow all instruc-

tions in this manual can result in equipment

malfunction, property damage, personal injury

and/or death.

After uncrating unit, inspect thoroughly for hidden damage.

If damage is found, notify the transportation company

immediately and file a concealed damage claim.

Top skid assembly should be left in place until after the unit

REDUCED EQUIPMENT LIFE AND PERSONAL INJURY

HAZARD

mproper installation, adjustment, alteration, service or

maintenance can void the warranty

.

The weight of the condensing unit requires caution and

proper handling procedures when lifting or moving to

avoid personal injury. Use care to avoid contact with

sharp or pointed edges.

CAUTION

!

Safety Precautions

1. Always wear safety eye wear and work gloves when

installing equipment.

2. Never assume electrical power is disconnected. Check

with meter and disconnect.

3. Keep hands out of fan areas when power is connected

to equipment.

4. R--22 causes frost--bite burns.
5. R--22 is toxic when burned.

Locating The Outdoor Unit:

Check local codes covering zoning, noise, platforms.
If practical, avoid locating next to fresh air intakes, vent or

windows. Noise may carry into the openings and disturb

people inside.
Placement of the unit should be in a well drained area or

unit must be supported high enough so runoff will not enter

the unit.
Do not locate where heat, lint or exhaust fumes will be

discharged on unit (as from dryer vents).
Roof top installations are acceptable providing the roof will

support the unit and provisions are made for water

drainage and the noise or vibration through the structure.
Do not install the unit in a recessed or confined area where

recirculation of discharge air may occur.
Allow sufficient space for airflow clearance, wiring,

refrigerant piping, and servicing unit.
