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.
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.
CAUTION
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 air conditioner and verify functionality before mounting the air conditioner, see HANDLING
AND TESTING THE AIR CONDITIONER on page 3.
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.
3. Using the gasket kit provided, install gaskets to air conditioner. See Mounting Gasket Kit on page
6for proper location.
4. Mount air conditioner on enclosure using mounting bolts and washers provided to secure unit to
enclosure. 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. Refer to the top of the 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.
6. When the unit is equipped with an automatic temperature controller, the controller is preset at the
factory for your convenience and should not require adjustment.
SYSTEM CONTROLS
LEVEL I TEMPERATURE CONTROLLER
The Level I controller is located inside the air
conditioner. To adjust, disconnect power to the air
conditioner. Open the front panel by loosening the front
panel screw. Refer to Figure 2 on page 7 to locate
the controller. Turn the controller adjustment screw
slot counter-clockwise to increase and clockwise to
decrease the temperature set point, see Figure 1.
The thermostat cooling setpoint is indicated by the
alignment of the adjustment screw slot with the dial
decal. After completing adjustment, close the front
panel and tighten the front panel screw. Restore power
to the air conditioner for operation.
LEVEL II AND III TEMPERATURE
CONTROLLER
The Level II and III controller is mounted on the air
conditioner front panel and is factory set for standard
operation. All operating parameters are programmable
for custom applications. Refer to the Level II and III
programming and Operating Instruction Manual, 10-
1008-161.
