RECEIVING THE AIR CONDITIONER

Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents, 

scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill. 

Damage should be brought to the attention of the delivering carrier -- NOT to Pentair Equipment Protection -- 

within 15 days of delivery. Save the carton and packing material and request an inspection. Then file a claim with 

the delivering carrier.
Pentair Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any 

way possible.

HANDLING AND TESTING THE AIR CONDITIONER

If the air conditioner has been in a horizontal position, be certain it is placed in an upright, vertical or mounting 

position for a minimum of five (5) minutes before operating.

Do not attempt to operate the air conditioner while it is horizontal 

or on its side, back or front. The refrigeration compressor is filled 

with lubricating oil. This will cause permanent damage to the air 

conditioner and also voids the warranty.

CAUTION

TEST FOR FUNCTIONALITY BEFORE MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.
Refer to the nameplate for proper electrical current requirements, and then connect the power cord to a properly 

grounded power supply. Minimum circuit ampacity should be at least 125% of the amperage shown in the design 

data section for the appropriate model. No other equipment should be connected to this circuit to prevent 

overloading.
Operate the air conditioner for five (5) to ten (10) minutes. No excessive noise or vibration should be evident 

during this run period. The condenser blower (ambient air), the evaporator blower (enclosure air), and the 

compressor should be running.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes. 
The compressor is provided with automatic reset thermal overload protection. This thermo-switch is located 

and mounted inside the plastic enclosure clipped to the compressor. The switch operates when the compressor 

overheats due to clogged or dirty inlet air filter or if ambient air temperatures exceed nameplate rating or if 

enclosure dissipated heat loads exceed the rated capacity of the air conditioner. The thermal overload switch will 

actuate and stop compressor operation. The blowers will continue to operate and the compressor will restart 

after it has cooled to within the thermal overload cut-in temperature setting.
