Order Parts 

When reporting shortages or damaged parts, or when ordering 

repair parts, give the complete unit model and serial numbers 

which are stamped on the unit rating plate. 

Standard Items 

The condensing unit consists of a completely assembled 

package which includes a compressor pack, condenser coils, 

fans, fan motors, outdoor control box, factory wiring, factory 

tubing and fittings.

Crankcase Heaters 

These units are equipped with a crankcase heater that is 

factory wired to operate whenever the main power supply to 

the unit is “ON” and compressors are “OFF.” Before starting 

the equipment after prolonged shutdown or at the time of initial 

spring startup, be sure that the circuits to the condensing units 

are closed for at least 24 hours. 

Corrosive Environment 

The metal parts of this unit may be subject to rust or 

deterioration if exposed to a corrosive environment. This 

oxidation could shorten the equipment’s useful life. Corrosive 

elements include salt spray, fog or mist in seacoast areas, 

sulphur or chlorine from lawn watering systems, and various 

chemical contaminants from industries such as paper mills and 

petroleum refineries.
If the unit is to be installed in an area where contaminants are 

likely to be a problem, special attention should be given to the 

equipment location and exposure.

• 

Avoid having lawn sprinkler heads spray directly on the 

unit cabinet 

• 

In coastal areas, locate the unit on the side of the building 

away from the waterfront.

• 

Shielding provided by a protection, based on clearances 

 DANGER

Disconnect all power to unit before starting maintenance. Failure to do so 

can cause electrical shock resulting in severe personal injury or death. 

Regular maintenance will reduce the buildup of contaminants 

and help to protect the unit’s finish.

• 

Frequent washing of the cabinet, fan blade and coil 

with fresh water will remove most of the salt or other 

contaminants that build up on the unit. 

• 

Regular cleaning and waxing of the cabinet with a good 

automobile polish will provide some protection. 

• 

A good liquid cleaner may be used several times a year 

to remove matter that will not wash off with water. 

Several different types of protective coatings are offered in 

some areas. These coatings may provide some benefit, but the 

effectiveness of such coating materials cannot be verified by 

the equipment manufacturer. 

Installation General 

The condensing unit should be installed outdoors. It should be 

located as near as possible to the evaporator section to keep 

connecting refrigerant tubing lengths to a minimum. The unit 

must be installed to allow a free air flow to the condenser coils
If several units are installed adjacent to each other, take care to 

avoid recirculation of air from one condenser to another. In all 

installations, adequate space must be provided for installation 

and servicing.
The unit must not be connected to any duct work. Do not 

locate unit under a roof drip; if necessary, install gutters, etc., to 

prevent water runoff onto the unit. To prevent air recirculation, 

it is recommended that the unit not be installed under an 

overhang. However, if this is necessary, allow a minimum of 

60” above the unit for air discharge
