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 nVent Equipment Protection -- within
15 days of delivery. Save the carton and packing material and request an inspection. Then le a claim with the
delivering carrier.
nVent 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 ve (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 lled
with lubricating oil. This will cause permanent damage to the air
conditioner and also voids the warranty.
CAUTION
TEST FOR FUNCTIONALITY MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.BEFORE
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 ve (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 lter 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.
