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. to 80ºF. Adjust the thermostat to its maximum setting.
4.
If your unit is equipped with an on-off switch, move it to the on position. Turn the electrical power on. Verify that the evaporator blower or fan is running.
5.
Adjust the thermostat to its minimum setting. 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. On units equipped with a low ambient kit, the start of the condenser fan or blower will be delayed until the system
pressures rise.
7.
Operate the air conditioner for appproximately 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.
On units equipped with heaters, adjust both the cooling and heating thermostats to their maximum settings. Verify that the compressor and condenser fan or blower has
stopped. Verify elevated discharge air temperature from the evaporator air discharge.
9.
If your unit is equipped with an on-off switch, leave it in the on position. Return the cooling thermostat to its original setting. If the unit is equipped with a heater, return
the heating thermostat to its original position.
10. Turn off the electrical power and disconnect the air conditioner from the power source.
11. 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
Kooltronic Air Conditioners have been engineered to be installed easily. To avoid damaging your air conditioner, please read the following information before installation:
1. Remove and save the four screws holding the Mounting Template and Assembly Bracket (M/TAB) to the unit. Remove the M/TAB.
2. Place the M/TAB flush against the outside of the cabinet to locate cutouts and mounting holes.
3. NOTE: The top cutout for the warm air return does not have to match the full 12" opening on the M/TAB. You can
locate your cutout anywhere within this opening. Locate your cutout close to the top and not less than 4" 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). Preferred positions: one in each corner and two near center on each side. 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 studs
located on each side panel into the slots on the M/TAB.
6. Insert the remaining 10-32 screws and seal washers supplied by Kooltronic through the Air Conditioner side panel
and into the M/TAB. To avoid misalignment of parts, install and slightly tighten all screws. Then secure all screws,
but do not to overtighten.
7. Attach overflow drain hose supplied to the drain exit in the side or bottom or lower side panel. This hose must not
be elevated above the exit port. Improper mounting will impede the flow of condensate and may cause internal
malfunctions.
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
KA4C4NP36
is 125 lbs. Additional technical
data can be found in the performance specifications in the Operator’s Manual
available online.
MOUNTING PLAN
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
