Installation Instructions
Model KA4C4RP33R
K_A4C4RP33R
I. Introduction
These instructions provide you with the general information necessary for proper installation of the air conditioners.
II. Incoming Inspection
Kooltronic Air Conditioners are designed, built and packaged to withstand the shock and vibration normally associated with shipment by common carriers. Occasionally
improper handling during shipping causes damage. Such handling could include unbanding of palletized shipments, failing to respect
"This Side Up"
arrows, rough
handling, falling off conveyors, excessive vibration, crushing, etc. Therefore, a thorough inspection should be done upon receipt of all shipments. Any carton tears, dents,
scratches, loose articles or evidence of oil are signs of damage and should be noted on the Freight Bill. Cartons should be opened promptly and the units inspected for
CONCEALED DAMAGE. Kooltronic Air Conditioners must be delivered in the proper mounting position to assure that damage to the compressor has not occurred during
shipping. Any Kooltronic Air Conditioner that is delivered removed from the banded pallet, lying down or double stacked should be refused.
An immediate claim MUST be filed with the freight carrier and an inspection requested. Retain all packing materials. Kooltronic cannot assume responsibility for Consignee's
failure to file a timely freight claim.
Kooltronic Air Conditioners must be operated in their proper mounting position. If attempts are
made to operate a unit that is not in its designed mounting position, permanent compressor
damage will occur. This action will void the warranty.
III. Pre-Installation Testing
1.
The unit must sit in an upright position at a minimum room temperature of 65ºF to allow the system to warm up.
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 75ºF.
4.
Heat up sensor bulb in evaporator compartment to 90ºF using heat pipe or light bulb.
5.
Turn the electrical power on. Verify that the evaporator blower or fan is running. The compressor should start. On units equipped with a short cycle protector, the compressor
will have a delayed start of six (6) minutes from the time power is applied to the unit.
6
Verify that the condenser blower or fan is running. The start of the condenser fan or blower will be delayed until the system pressures rise.
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 70ºF when the room temperature is between
70ºF and 80ºF.
8.
Turn off the electrical power and disconnect the air conditioner from the power source.
9.
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.
IV. Mounting
1.
Loosen two screws on the bottom of the unit.
2.
Place the M/TAB flush against the outside of the enclosure to locate cutouts and mounting holes.
3.
NOTE: The top cutout for the warm air return does not have to match the full 7.75" opening on the M/TAB.
You can locate your cutout anywhere within this opening. Locate your cutout close to the bottom and not
less than 3" high. Make sure the cutouts don't interfere with components inside your cabinet.
4.
Mount the M/TAB to the outside of the cabinet using all the mounting hardware supplied by Kooltronic (
1/
4
-
20 screws/nuts/washers). NOTE: Make sure the screws are inserted with heads on M/TAB side. Tighten
nuts securely.
5.
Route the power cord through the top cut out in your cabinet. Mount the unit to the M/TAB by sliding the
slots located on the front panel on the hooks of the M/TAB.
6.
Tighten two screws on the bottom of the unit and seal the unit against the enclosure.
7.
Attach overflow drain hose supplied to the drain exit in bottom of the unit.
NOTE: The installer has the option of mounting the Air Conditioner to the M/TAB using torx temper screws
instead of hex screws. The (2) torx temper are supplied by Kooltronic in the hardware bag.
Dimensions, inches [mm], are for reference only and are subject to change.
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 weight of the unit is 98 lbs. Additional technical
data can be found in the performance specifications in the Operator’s Manual available online.
CAUTION
Kooltronic Air Conditioners must be standing in their 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
