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 instal-
lation.
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 particularly in winter months.
2. Refer to the identification label 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 (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 should be 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.
