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. This is particularly important during winter months.

2. Refer to the identification label 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. Condenser impeller should start immediately and after one (1) second, stop.

7. After three (3) to five (5) minutes the condenser impeller should start.

8. Verify that the condenser blower or fan is running.

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 discharged should be less than 70

o

F when the

room temperature is between 70

o

F and 80

o

F.   

10. If ambient temperature is below 75

o

F, after fifteen (15) minutes the thermostat will shut off the

compressor and the condenser impeller.

11. Turn off the electrical power and disconnect the air conditioner from the power source. 

12. 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

o

from its proper

mounting position.
