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 70
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 temperature on the digital display. The thermostat must be set a minimum of 10°F below
this temperature for the compressor to operate (the factory setting is 75°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 a 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.
VII. Specific Model Data
Mounting
The Kooltronic Special Purpose Air Conditioners K2NA6C30EP56TR-BR have been engineered to be installed
easily. Prior to mounting, refer to pages 10 and 11 for the drawings showing dimensions and locations of mounting
holes and cutouts. Prior to cutting or drilling, make sure that cutouts and mounting holes do not interfere with
components inside the cabinet. To avoid damaging your air conditioner, please read the following information
before installation:
1. It is recommended that a lift truck be used for installation.
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.
