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 Pentair
Equipment Protection if further information is required.
IMPORTANT NOTICE
• These instructions were authored in English. Instructions published in languages other than English have been
translated from the authored language.
• These air conditioners are intended to be used by properly trained customers in industrial, communications and
agricultural environments.
• Operating sound level is below 70 dBA.
WARNING
Disconnect the power source from
the air conditioner before servicing.

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 Pentair Equipment Protection -within 15 days of delivery. Save the carton and packing material and request an inspection. Then file a claim with
the delivering carrier.
Pentair 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 five (5) minutes before operating.
CAUTION
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 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 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 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 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 INSTRUCTIONS
1. Inspect the air conditioner and verify correct functionality before mounting the air conditioner. See
HANDLING AND TESTING THE AIR CONDITIONER on page 3.
2. Determine if the unit is to be surface or recess mounted. Using the appropriate cutout dimensions,
see Mounting Cutout Dimensions on page 5 of this manual, prepare the enclosure opening for
either surface or recess mounting.
3. Using the gasket kit provided, install gaskets to air conditioner.
4. Mount air conditioner on enclosure using 1/4-20x.625 mounting bolts provided. “EZ” mount tabs
can be used to hold unit on enclosure while mounting in place. Torque each bolt to 65 in./lbs. Allow
unit to remain upright for a minimum of five (5) minutes before starting. Caution! Air conditioner
must be in upright position during operation.
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
INSTRUCTIONS COULD RESULT IN OVERFLOWING OF THE CONDENSATE DRAIN PAN.
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.
