RECEIVING THE AIR CONDITIONER
Inspect the air conditioner and check for concealed damage that may have occurred during shipment. Damage
evident upon receipt should be noted on the freight bill. Save the packing material and request an inspection.
Then file a claim with the delivering carrier within 15 days of delivery.
McLean Cooling cannot accept responsibility for freight damages; however, we will assist you in any way
possible.
HANDLING & 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.
Warning: 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.
TEST FOR FUNCTIONALITY BEFORE MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.
Refer to the nameplate for proper electrical current requirements, and then wire unit 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.
Immediately after applying power the evaporator blower (enclosure air) should start running. Operate the air
conditioner with the compressor running for five (5) to ten (10) minutes. You will need to set the cooling
thermostat below the ambient temperature to operate the compressor.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes after the
condenser air blower starts.
See sequence of operation for specifics on how the unit operates when powered up.
