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.
III. Product Handling:
1) Do not attempt to operate your Kooltronic Air Conditioner until you read and thoroughly understand
this Manual. See section VI PRE-INSTALLATION TESTING.
2) Before operating the Kooltronic Air Conditioner be certain that it is placed in its correct mounting
position. All Air Conditioners containing an MM, NM, P, or V as part of the model number are
designed to operate in a vertical position only. All Air Conditioners containing an H, RT or
RM in the model number are designed to operate in a horizontal position only. This placement
must be done a minimum of 5 minutes prior to operating in order to allow the compressor oil to drain
to the compressor sump area.
CAUTION
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. To avoid compressor
damage do not tip the unit more than 45° from its proper mounting position.
3) Before operating this unit, all electrical wiring must be checked to assure the proper connection to
the correct power source. Minimum circuit ampacity should be at least 125% of the amperage found
on the air conditioner label for the corresponding voltage. Do not exceed the maximum fuse size
found on the label.
4) PROCEDURE FOR PROPER PACKING AND SHIPMENT OF KOOLTRONIC
AIR CONDITIONERS:
■
■
■
■
Keep Air Conditioner in proper upright position indicated by arrow markers.
Pack Air Conditioner in an appropriate carton (preferably original carton if possible), with
adequate internal protective packaging, making sure carton is marked and is kept in correct
upright position.
For local, controlled transportation, strap carton to a secure part of truck to prevent falling
or sliding, minimize vibration, etc.
For common carrier shipment, band unit(s) securely to a pallet. Unpalleted shipment risks
severe damage which voids the warranty.

ENCLOSURE
Kooltronic Air Conditioners are required when the equipment operating temperature must be kept near or lower
than the ambient room temperature, and/or the cabinet must be sealed from dust, fumes, oil, corrosives and other
contaminants. This Air Conditioner utilizes a "Closed-Loop Cooling System" to ensure optimum performance of the
installed components.
Closed-Loop cooling seals the electronics enclosure from hostile elements in the environment. Two separate
circulation systems are employed. The internal system cools and dehumidifies the air inside the cabinet, totally
isolating the sensitive electronics and other components from the environment. The external system uses
circulating ambient air or water to discharge the heat removed from the electronics.The heat is dissipated from the
enclosure by means of the vapor compression refrigeration cycle. This takes place in a hermetically-sealed
refrigeration system, utilizing either an air-cooled or water-cooled condenser heat exchanger. The warm air inside
the enclosure is drawn through the evaporator coil where it is cooled, dehumidified and returned.
Any enclosure moisture accumulated on the evaporator coil is collected in the condensate tray and released to the
ambient air through the drain tube or the condensate evaporator.
The heat removed through the evaporator coil is transferred by the compressed refrigerant to the condenser coil.
Ambient air or water is then passed through the condenser coil, where it absorbs the heat and is then discharged
to the environment.
The cool air discharge temperature is regulated by the capacity control (hot gas bypass) valve. The unit is
equipped with a Low Temperature Thermostat to prevent over-cooling. In applications having frequent voluntary
heat load interruptions, an optional Compressor Short Cycle Protector is recommended.

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
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.
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 identification label 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 typically 75 to 80°F.
4. Adjust thermostat to its maximum setting.
5. If your unit is equipped with an on-off switch, move it to the on position.
6. Turn electrical power on.
7. Verify that the evaporator blower or fan is running.
8. 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 6 minutes from the time power is
applied to the unit.
9. Verify that the condenser blower or fan is running. Note, on units equipped with a low ambient kit, the
start of the condenser fan or blower will be delayed until the system pressures rise.
10. Operate the air conditioner for approximately ten 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 should be discharged should be less than
70°F when the room temperature is between 70 and 80°F.
11. 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.
12. 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 unit is equipped with a heater, return the heating thermostat to
its original position.
13. Turn off the electrical power source, and disconnect the air conditioner from the power source.
14. If any cover plug is removed to adjust the unit, make certain to put back in place to maintain the
integrity of the closed-loop airflow system.
NOTE:
Before shipment all Kooltronic, Inc. Air Conditioners are subjected to a performance test.

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. See Figure 1 for proper M/TAB orientation.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 9" 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). 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 do not tighten any
of the screws until they are all installed. Be careful not to overtighten the screws.
7. The drain hose must not be elevated above the exit port. Improper mounting will impede the
flow of condensate and may cause internal malfunctions.
CAUTION
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 performance specifications.

VIII. Maintenance
Kooltronic Water-Cooled Air Conditioners require no maintenance. Air-Cooled Air Conditioners are
designed to require only the routine cleaning of air filters to assure unimpeded air flow through the
condenser heat exchanger. It is not possible to recommend specific filter cleaning intervals since the level
and the nature of airborne particulate matter differs widely with each installation. It is generally sufficient
to remove and wash the reusable aluminum mesh air filters when the outer surfaces of these filters
appear covered with a thin layer of dust or lint. Filter recoating adhesive is recommended. Appropriate
disposable filters are available from Kooltronic.
If filter service is neglected or delayed, the air conditioner will not perform at its design capacity. The first
indication of excessively clogged air filters is usually a gradual increase of temperature within the
equipment cabinet. If operation is continued under these conditions, the compressor will be shut off by
the thermal overload device. The compressor will restart when its external temperature drops below the
protector threshold setting and the compressor will continue to cycle on and off. Continued operation
under these conditions will cause damage, shorten compressor life and void the warranty.
A. Filter Removal and Service
Kooltronic Air Conditioners feature an easily removable inlet filter to facilitate necessary cleaning.
CAUTION
Do not operate the Air Conditioner for extended periods of time with the filter
removed. The condenser coil may become clogged with dust or lint from the air
entering the face. A clogged condenser coil is not readily detected and will give
the same reaction as a clogged filter. A clean filter is the best protection.
1) Lift the filter, using the attached tab, to clear the lower filter retainer. Pull filter toward you and
downward until the top of the filter clears the upper filter retainer.
2) After removal, the filters should be flushed under warm running water with the clean side
up, driving contaminants out the dirty side of the filter. If the accumulated dirt is oily, washing in
a detergent bath is recommended, followed by a warm water rinse as above.
3) The filters may be sprayed with Kooltronic A-16 Filter Recoating Adhesive to trap fine airborne
contaminants, or they may simply be dried and reinstalled as strainer type filters. Recoating is
recommended for best results.
4) Reinstall the filter: (a) keeping the tab at the bottom, slide filter into the upper retainer, (b) press
filter against the unit and (c) slide down into lower retainer.
11
B. Blowers
The design life of the blowers employed in all Kooltronic Air Conditioners is substantially in
excess of 20,000 hours. All Kooltronic condenser and evaporator blowers are equipped with
UL/CSA permanently-lubricated precision ball-bearing motors, with automatic-reset thermal
overload protectors.
CAUTION
Before opening the Air Conditioner, disconnect all power.
If field replacement of a blower motor is necessary, most blower assemblies, including mounting
plate, are readily removable. Each of the blower mounting plates is held to the air conditioner
cabinet structure by screws and nuts. For installation of the replacement blower, electrical
connections may be broken at the terminal block, or power leads may be cut and appropriately
spliced together.
C. Compressor
All Kooltronic compressors are approved by UL and CSA, and require no maintenance.
They are hermetically sealed and charged at the factory, and equipped with automatic-reset
thermal overload protectors.
If the compressor or the hot gas bypass valve fails, it is strongly recommended that the Air
Conditioner be returned to Kooltronic for service.
D. Refrigerant Loss
Kooltronic Air Conditioners are subjected to a series of tests to detect refrigerant leaks, during
and after manufacture. It is possible that shipping or other damage, or microscopic leaks over a
long period, may result in the need for replenishment of refrigerant charge. When it has been
verified by a qualified professional that a refrigerant shortage does exist, the leak must be
repaired. Then the unit may be evacuated and recharged in the field by qualified service
people only.
CAUTION
Refer to the data on the unit name plate which specifies the type of refrigerant
and the amount of charge in ounces.
E. Relocation
If your Kooltronic Air Conditioner has to be moved to another location by truck, the following
precautions should be taken:
De-mount Air Conditioner from equipment, controller or enclosure.
Conform to the applicable provisions of PROCEDURE FOR PROPER PACKING AND
SHIPMENT OF KOOLTRONIC AIR CONDITIONERS in this manual under Section III.
"PRODUCT HANDLING".

IX. Trouble-Shooting
Each Kooltronic Air Conditioner is engineered for performance and built for reliability. They are
designed to require no routine maintenance other than the cleaning of ambient air filters. If
your air conditioner should require warranty service, please contact Kooltronic. If
you require service out of warranty, we have compiled a trouble-shooting chart to
assist your service personnel. If additional assistance is required contact Kooltronic at
