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, and 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.
