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.
Immediately after applying power the evaporator blower (enclosure air) should start running. Operate the air
conditioner with the compressor running for five (5) to ten (10) minutes.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes after the
condenser air blower starts.
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. Using the mounting gasket kit provided with the unit, install gaskets to the air conditioner. See
Mounting Cutout Dimensions on page 5 of this manual.
3. Mount air conditioner on enclosure taking care not to damage the mounting gasket. The
mounting gasket is the seal between the air conditioner and the enclosure. Avoid dragging the air
conditioner on the enclosure with the mounting gasket attached as this could cause rips or tears
in the gasket and risk losing the water tight seal.
4. 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 nameplate for electrical requirements. Wire the unit to a properly grounded power
supply. Electrical circuit should be fused with slow blow or HACR circuit breaker.
6. The air conditioner requires a remote mounted thermostat and has an alarm feature. Wire the
thermostat and alarm outputs to the appropriate terminals on the 24VAC terminal strip (note
locations on the wiring diagram).
7. Set thermostat for required cabinet temperature. See Standard and Optional Component
Operation on page 6.

1. Identifies the type/family of air conditioner and the approximate height (i.e. T62 = Outdoor family
about 62” high).
2. This is the air conditioner’s listed capacity in Btu/hr at rated conditions. (i.e. 22 = 22,000 BTU/Hr. at

3. 1 = 115 Volt, 2 = 230 Volt, 4 = 460 Volt.
4. 6 = 50/60 Hz or 60 Hz only.
5. Unique set of numbers for each air conditioner which identifies the accessories on a model.

TECHNICAL INFORMATION
SEQUENCE OF OPERATION
The air conditioner comes standard with two internally mounted thermostats. There are two modes of
operation; heating and cooling. During heating and cooling modes the evaporator fan will be running.
HEATING
When the enclosure temperature is below the heating thermostat setpoint, power is applied to the
heaters. When the enclosure temperature is 10 degrees above the setpoint the heater is powered off.
COOLING
When the enclosure temperature is above the cooling thermostat setpoint, power is applied through the
dual pressure control, then to the time delay relay. After the delay time the contactor is energized and the
compressor starts. The condenser fan will start once the condenser discharge air temperature gets above
70 F. Component specific information is listed below.
Operating the air conditioner below the minimum ambient temperature or above the maximum ambient
temperatures indicated on the nameplate voids all warranties.
The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube
continuously this can only mean that ambient air is entering the enclosure. Be aware that frequent
opening of the enclosure’s door admits humid air that the air conditioner must then dehumidify.
STANDARD AND OPTIONAL COMPONENT OPERATION
THERMOSTAT
The T62 air conditioner uses a 10-1061-16 thermostat. The thermostat setpoint equals the temperature
that the air conditioner turns off. The thermostat has a 10 F differential from setpoint until it calls for
cooling or heating. An example of operation is shown below.
For cooling (75-100 F range):
Tstat setpoint = 75 F
Cooling turns on at 85
Cooling turns off at 75 F
For heating (55-65 F range):
Tstat setpoint = 55 F
Heating turns on at 55 F
Heating turns off at 65 F
Note: For testing purposes only, the thermostat stop screw may be removed (on units so
equipped) to allow settings below 70 F. After testing, replace the stop screw and verify that
the thermostat can not be set below 70 F. Extended operation below 70 F can cause coil
freeze ups resulting in reduced load and/or unit damage.
DUAL PRESSURE CONTROL
LP cutout 30 psi, HP cutout 520 psi
The dual pressure control will prevent the compressor from operating when the system experiences low
pressure (i.e. loss of charge) or high pressure (i.e. a blocked condenser coil). The low pressure cutout is an
automatic reset and the high pressure cutout is a manual reset. An optional alarm relay will be activated if
this event occurs.
TIME DELAY RELAY
• Factory set for 3 minutes (top dial at 1-10 minutes, bottom dial at 3).
• The purpose of the time delay relay is to prevent short cycling of the compressor.
HEAD PRESSURE CONTROL
• Unit is set at the factory, no adjustment necessary.
• At condenser discharge temperatures below 70 F, the condenser fan is not powered and the LED’s are not lit.
• At temperatures between 70-100 F the yellow LED is lit and the fan is being regulated under full speed.
• At temperatures above 100 F the green LED is lit and the fan is operating at full speed.
