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°F to allow the system to
warm-up. This is particularly important during winter months.
2. Refer to the nameplate for proper electrical voltage and current requirements. Connect the power cord
to a properly grounded and fused electrical supply, leaving electrical power to the unit turned off.
3. Note the factory thermostat setting which is 75
o
F.
4. Turn the electrical power on.
5. Verify that the evaporator blower or fan is running.
6. Verify that the condenser blower or fan is running. It will start running after three (3) to five (5) minutes.
7. Operate the air conditioner for approximately ten (10) minutes. During this period no unusual noise or
vibration should be evident. Both the evaporator and condenser fans or blowers should be delivering
air through their respective discharge ports. The cool air discharged should be less than 70°F when
the room temperature is between 70°F and 80°F.
8. Turn off the electrical power and disconnect the air conditioner from the power source.
9. If any cover plug was removed to adjust the unit, be sure to replace it in order to maintain the integrity
of the closed-loop airflow system.
NOTE:
Before shipment all Kooltronic Air Conditioners are subjected to a performance test.

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.
