VI. Pre-Installation Testing
Before mounting the air conditioner to the enclosure, test for proper operation. This will verify the shipping integrity of
the system. Please follow the steps below prior to installation.
CAUTION
1.
The unit must sit in an upright position at a minimum room temperature of 65
o
F to allow the system to warm up.
2.
Note that the factory Low Temperature Thermostat (compressor) setting is 92
o
F with a differential of 7
o
F (Cooling
Mode, Cut out at set point), and that the Heater Thermostat setting is 45
o
F with a differential of 5
o
F (Heating Mode,
Cut out at set point).
3.
Refer to the identification label for proper electrical voltage and current requirements. Connect the power cord
from the rear of the unit to a properly grounded and fused electrical supply, leaving electrical power to the unit
turned off.
4.
Plug the remote control 3 position connector into the unit receptacle labeled “Control.” Plug the remote control
power cord into the unit receptacle labeled “Thermostat Power.”
5.
Turn the electrical power on.
6.
Verify that the evaporator blower is running. (The remote control includes a compressor time delay. After operating
three (3) minutes the unit will run in cooling mode.)
7.
Heat up the cooling thermostat sensor with a heat gun. When the cooling thermostat display temperature reaches
100
o
F the air conditioner should start. Keep the cooling thermostat temperature above 93
o
F.
8.
After four (4) to seven (7) minutes the condenser impeller should start.
9.
Operate the air conditioner for ten (10) minutes. During this period no unusual noise or vibration should be evident.
The condenser impeller could cycle during this period of time. The cool air discharge should be at least 15
o
F lower
than the ambient temperature.
NOTE:
Before shipment all Kooltronic Air Conditioners are subjected to a performance test.
6
The air conditioner must be standing in its proper mounting position for a minimum of five (5) minutes prior to
testing. Failure to follow this procedure will cause permanent damage to the compressor. To avoid compressor
damage do not tip the unit more than 45° from its proper mounting position.
