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 wire the unit to a properly grounded
power supply using copper conductors only. Power supply wiring should be restrained after field installation to
ensure no contact with internal fan. Minimum circuit ampacity should be at least 125% of the amperage shown on
the unit nameplate. 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. You will need to set the cooling
thermostat below the ambient temperature to operate the compressor.
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.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes after the
condenser impellers start.
See Sequence of Operation on page 6 for specifics on how the unit operates when powered up.
HOW TO READ MODEL NUMBERS
N17 01 2 6 G010
12345
1. Identifies the type/family of air conditioner and the approximate height (i.e. N17 Narrow family
about 17 inch high).
2. This is the air conditioner’s listed capacity in BTU/Hr. at rated conditions. (i.e. 01 = 1000 BTU/Hr. at
125/125a F)
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.

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.
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 to include either a slow-blow fuse or an HACR circuit breaker.
6. Some air conditioners require a remote mounted thermostat. Wire the thermostat outputs to the
appropriate terminals on the 24 VAC terminal strip by noting the locations on the correct wiring
diagram.
7. Set thermostat for required cabinet temperature. Refer to Sequence of Operation on page 6 for
thermostat adjustment and operation.

TECHNICAL INFORMATION
SEQUENCE OF OPERATION
The air conditioner comes standard with an internally mounted thermostat. The front cover must be removed in
order to gain access to the thermostat which is located to the right of the LCD display as shown below.
COOLING
When the enclosure temperature is above the cooling thermostat setpoint, power is applied through the
thermostat and the compressor is then energized. The condenser fan will start immediately. 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. DO NOT set the enclosure thermostat to a
temperature lower than 70 F. Doing so can increase the likelihood of frost buildup on the evaporator coil.
For optimal operation, and energy conservation, set the thermostat to the highest temperature that the
enclosure equipment is rated to.
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 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. An example of operation is shown below.
FOR COOLING (75100 F RANGE):
• Thermostat setpoint = 80 F
• Cooling turns on at 90 F
• Cooling turns off at 80 F
460 V TO 230 V TRANSFORMER (N170X46GXXX ONLY)
The 230 V from this transformer powers the compressor, fans and optional transformers.
230 V TO 10 V TRANSFORMER (OPTIONAL)
This transformer powers the temperature display only.
230 V TO 24 V TRANSFORMER AND RELAY (OPTIONAL)
The transformer and relay are used to operate the condenser blower and compressor by using a customer
supplied, remote mounted door switch. This is not a safety door switch, but rather, only helps to reduce
condensation at the evaporator coil if the door is opened. The unit will remain electrified when the door
switch is operated with the evaporator fan continuing to operate, and potentially, if temperatures are low
enough, the heater may continue to operate on outdoor models.

MAINTENANCE
COMPRESSOR
The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should
provide years of satisfactory operating service.
Under no circumstances should the access fitting covers be loosened, removed or tampered with.
Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system.
Recharging ports are provided for the ease and convenience of certified refrigeration repair service personnel for
recharging the air conditioner.
INLET AIR FILTER
This air conditioner was designed with a dust resistant condenser coil. This allows it to be run filterless in most
applications. The air conditioner is shipped with a filter in place for your convenience. For filterless operation,
simply remove the filter. Should you decide the filter is necessary in your application, regular maintenance
to clean this filter will assure normal operation of the air conditioner. The easily removable inlet air filter is
located inside the filter slot opening in the front cover. If necessary filter maintenance is delayed or ignored, the
maximum ambient temperatures under which the unit is designed to operate will be decreased.
If the compressor’s operating temperature increases above designed conditions due to a dirty or clogged filter
(or plugged condenser coil), the air conditioner’s compressor will stop operating due to actuation of the thermal
overload cut-out switch located on the compressor housing. As soon as the compressor temperature has dropped
to within the switch’s cut-in setting, the compressor will restart automatically. However the above condition will
continue to take place until the filter or coil has been cleaned. It is recommended that power to the air conditioner
be interrupted intentionally when abnormally high compressor operating temperature causes automatic shut-
down of the unit. The above described shut-down is symptomatic of a clogged or dirty filter, thus causing a
reduction in cooling air flow across the surface of the compressor and condenser coil.
HOW TO REMOVE, CLEAN OR INSTALL A NEW INLET AIR FILTER
Aluminum washable air filters are designed to provide excellent filtering efficiency with a high dust holding
capacity and a minimum amount of resistance to air flow. Because they are constructed entirely of aluminum
