VII. Pre-Installation Testing

Before mounting the air conditioner to the enclosure, test for proper operation to verify the shipping integrity of
the system. Pre-installation testing must be done in a non-hazardous location.

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. Turn the electrical power on by turning the switch on the front panel to ON. 

4. Observe the temperature on the digital display. The thermostat must be set a minimum of 5°F below this

temperature for the compressor to operate (the factory setting is 80°F). To adjust the thermostat, push
the SET button for two (2) seconds, then use the arrows to set the temperature. To store the new set
point value push the SET key again, or wait ten (10) seconds.

5. Verify that the evaporator blower or fan is running.

6. After one (1) minute the condenser blower and compressor should start.

7. Verify that the condenser blower is running.

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. Reset the thermostat to the factory setting (80°F).    

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

NOTE:

Before shipment all Kooltronic Air Conditioners are subjected to a performance test.

CAUTION

VIII. Customer Enclosure Requirements

1

. The internal air conditioner pressurized volume is 2.4 cu. ft. as shown on the air conditioner name plate.

This volume must be added to the customer enclosure volume for proper selection of the
Purge/Pressurized Control System.

Air conditioner air leakage is 0.1 CFM at pressure 0.25 i.w.g. For other pressures see the table in
“Principles of Operation on page 6. This air leakage should also be taken into account for proper
selection of the Purge/Pressurized Control System.

2. The air conditioner must be connected to the main enclosure’s (panel’s) power, which must be de-energized

10

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.

If the air conditioner is mounted to the cabinet door you must be sure that the door hinges will

support the additional weight of the air conditioner. Also be certain that when the door is

opened fully, the cabinet does not become unbalanced. The actual weight of the unit can be

found in the Technical Data.
