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.
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
impeller (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.
INSTALLATION
Step 1: Inspect air conditioner. Verify functionality before mounting the air conditioner, see
Handling & Testing the Air Conditioner on page 1.
Step 2: Using the cutout dimensions shown in this manual, prepare the air “IN” and air “OUT”
openings, and mounting bolt hole pattern for the enclosure.
Step 3: Using the gasket kit provided, install gaskets to air conditioner. See gasket kit illustration
in this manual for proper location.
Step 4: Mount air conditioner on enclosure using mounting bolts and screws provided. “EZ”
mount tabs can be used to hold unit on enclosure while mounting in place. Allow unit to remain
upright for a minimum of five (5) minutes before starting. Caution: Air conditioner must be in
upright position during operation.
Step 5: When routing the drain tube, caution should be taken to keep it from kinking or being
elevated above the exit point of the air conditioner. The drain tube must be on a continuous
downward slope. A slight elevation of the tube could result in secondary trap. FAILURE TO
FOLLOW THESE INSTUCTIONS COULD RESULT IN OVERFLOWING OF THE
CONDENSATE DRAIN PAN.
Step 6: Refer to top of nameplate for electrical requirements. Connect the power cord to a
properly grounded power supply. Use of an extension cord is not recommended. Electrical
circuit should be fused with slow blow or HACR circuit breaker.
