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 le 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 ve (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 lled
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 eld 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 ve (5) to ten (10) minutes. You will need to set the cooling thermostat or
controller setpoint below the ambient temperature to operate the compressor.
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 4 for specics on how the unit operates when powered up.
HOW TO READ MODEL NUMBERS
N36 06 2 6 G150
12345
1. Identies the type/family of air conditioner and the approximate height (i.e. N36 = Global family about 36
inch high).
2. This is the air conditioner’s listed capacity in BTU/Hr. at rated conditions. (i.e. 06 = 6,000 BTU/Hr. at 131/131 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 identies 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 o.
Cooling
When the enclosure temperature is above the cooling thermostat setpoint, power is applied through the
thermostat. The compressor is then energized either directly or through a contactor if unit requires one. The
condenser impellers will start immediately if the unit is not equipped with an optional head pressure control
switch. If the unit is equipped with an optional head pressure control switch, the condenser impellers will
start once the refrigerant pressure reaches the setting of the switch. Component specic 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.
The moisture that the enclosure air can contain is limited. If moisture ows 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 G52 air conditioner uses our standard 10-1061-16 thermostat. The thermostat setpoint equals the
temperature that the air conditioner turns o. The thermostat has a 10 F dierential from setpoint until it calls
for cooling or heating. 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 o at 80 F
For heating (55-65 F range):
• Thermostat setpoint = 55 F
• Heating turns on at 55 F
• Heating turns o 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 cannot be set below 70 F. Extended operation below 70 F can cause coil freeze ups
resulting in reduced load and/or unit damage.
Remote Access Control (optional)
See REMOTE ACCESS CONTROL (optional) on page 11
Head Pressure Control
Unit is set at the factory, no adjustment necessary.
At a saturated condenser temperature of 85 F (95 psig), the condenser fans will power o. At a saturated
condenser temperature of 118 F (165 psig), the condenser fans will power on.

Contactor
The contactor on the 1-phase 115V model uses a 115V coil (controller option only).
The contactor on the 1-phase 230V model uses a 230V coil (controller option only).
The contactor on the 3-phase model uses a 230V coil (controller option only).
Phase Monitor (N360X46GXXX only)
The phase monitor protects the compressor from reverse operation. When both lights on the monitor are lit
constant, the power to the unit has been wired correctly and the compressor will operate as designed.
If both lights on the monitor are not on constant, swap the power leads at the terminal block until both lights
are on constant.
Factory Settings:
Top dial set at 480 V for 60 Hz operation (Reset to 440 V for 50 Hz operation)
Middle dial set at 5 seconds
Bottom dial set at -20%
460 V to 230 V Transformer (N360X46GXXX only)
The 230 V from this transformer powers the fans, contactor and optional transformers. 460 V is only used to
run the compressor.
115/230 V to 10 V Transformer (optional)
This transformer powers the temperature display only.
115/230 V to 24 V Transformer and Relay (optional)
This transformer and relay are used to start/stop the unit by using a customer supplied, remote mounted door
switch.
