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. Allow the unit to sit in a upright position at a room temperature of 65°F minimum, allowing the system
to warm-up. This is particularly important in winter months.
2. Refer to the nameplate for proper electrical voltage and current requirements. Then connect the power
cord to a properly grounded and fused electrical supply. Leave the electrical power off.
3. Note the factory thermostat setting is 75°F.
4. Heat up sensor bulb in evaporator compartment to 90°F using heat pipe or light bulb.
5. Turn electrical power on.
6. Verify that the evaporator blower or fan is running.
7. The compressor should start. On units equipped with a short cycle protector, the compressor will have a
delayed start of 6 minutes from the time power is applied to the unit.
8. Verify that the condenser blower or fan is running. Note, the start of the condenser fan or blower will be
delayed until the system pressures rise.
9. Operate the air conditioner for approximately ten 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 and 80°F.
10. Turn off the electrical power source, and disconnect the air conditioner from the power source.
11. If any cover plug is removed to adjust the unit, make certain to put back in place to maintain the integrity
of the closed-loop airflow system.
NOTE:
Before shipment all Kooltronic, Inc. 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.
