NOTE: Some of the information in this manual may not apply if a special unit was ordered. If
additional drawings for a special unit are necessary, they have been inserted. Contact McLean
Thermal if further information is required.
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 McLean Thermal -- within 15 days of delivery. Save the carton and
packing material and request an inspection. Then file a claim with the delivering carrier.
McLean Thermal cannot accept responsibility for freight damages; however, we will assist you in
any way possible.
HANDLING & TESTING THE AIR CONDITIONER
If it is necessary to place the air conditioner in a horizontal position after unpacking, be certain it
is placed in an upright, vertical or mounting position for a minimum of five (5) minutes before
operating.
Never attempt to operate the air conditioner while it is horizontal or on it’s side, back or front. The
refrigeration compressor is filled with lubricating oil. Running the compressor without oil in the
lower part of the housing will cause permanent damage to the air conditioner. This also voids the
warranty.
TEST FOR FUNCTIONALITY
BEFORE
MOUNTING THE AIR CONDITIONER TO THE
ENCLOSURE.
Refer to nameplate for proper electrical current requirements, then connect 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.
