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.  

 7. Observe the temperatue on the digital display. The thermostat must be set at a minimum of 10

o

F below 

this temperature for the compressor to operate (the factory setting is 75

o

F). Refer to page 6 for 

instructions on adjustment of the thermostat. 

 8. 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. It is normal for the condenser blower to cycle on/off during this period.   

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

10. 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.
