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.
Allow the unit to sit in a upright position at a room temperature of 65°F minimum, allowing the system to warm-up.
This is particularly important in winter months.
2.
Refer to the nameplate 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 which is 75°F.
4.
Turn electrical power on.
5.
Verify that the evaporator blower or fan is running.
6.
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.
7.
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 and 80°F. It is normal for the condenser blower to cycle on/off during this period.
8. Turn off the electrical power source, and disconnect the air conditioner from the power source.
9. If any cover plug is removed to adjust the unit, make certain to put it back in place 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 K_A4C2DSP23L have been engineered to be installed easily. The air
conditioner is designed for two mounting options - external and internal.
NOTE: Prior to mounting of Air Conditioner units, refer to Mounting Drawings section of the Kooltronic website:
Access Series DSP23 115 Volt Mounting Drawings
Access Series DSP23 230 Volt Mounting Drawings
Prior to cutting or drilling, make sure that cutouts and mounting holes do not interfere with components inside the cabinet. The
Mounting Drawings are also available on the following pages.
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.
