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 M, P, or V as part of the model number are designed to operate
in a vertical position only. All Air Conditioners containing an H 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) We do not recommend that Air Conditioners be shipped to their final destination attached to an enclosure.
In the event that the Air Conditioner needs to be shipped attached to an enclosure it is strongly
recommended that proper support be provided for the Air Conditioner. Excessive vibration can occur if Air
Conditioners are not properly supported when shipped on enclosures, increasing the potential for internal
damage and voiding the warranty.
5) 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.

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. These Air Conditioners utilize a "Closed-Loop Cooling System" to ensure
optimum performance of the installed components.
Closed-Loop cooling seals the electronic 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
3
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 removed through the drain tube to the condensate
evaporator. Condensate evaporates in the condensate evaporator and is
1
2
4
released to the ambient air by the condenser impeller.
The heat removed through the evaporator coil is transferred by the compressed
refrigerant to the condenser coil. Ambient air is then passed through the
70ºF - Connect 1 and 2
condenser coil, where it absorbs the heat and is then discharged to the
75ºF - Connect 1 and 3
environment.
79ºF - Connect 1 and 4
Kooltronic Air Conditioners are designed to operate continuously in order to
eliminate compressor cycling, which shortens compressor life and causes line
transients. This unit is also equipped with a Low Temperature Thermostat to
prevent the evaporator coil from freezing. In conditions of low ambient
temperature and low enclosure load, the thermostat regulates the return air
temperature from 75°F to 86°F. The standard set point of the Low Temperature
Thermostat Jumper
Thermostat is 75°F. The set point can be changed to 70°F or to 79°F by
changing the location of the thermostat jumper (See illustration at right).
The Low Temperature Thermostat has a test start relay. When the air conditioner is turned on it will run
constantly for the first 15 minutes regardless of external temperatures. Afterwards, if the entering evaporator
air temperature is lower than the thermostat set point, the compressor and condenser blower will stop, and
the thermostat will begin to control the air conditioner.
5
The heater kit consists of a heater, a heat control thermostat and a heater limiter. The heater control
thermostat is a bimetal disk with a fixed set point of 60°F. When the entering evaporator air temperature rises
above 60°F the heater shuts off, and when the evaporator air temperature falls below 40°F the heater will
engage. The contact points of the alarm thermostat are normally closed. If the entering evaporator air
temperature exceeds 120°F the alarm thermostat contacts open, and when the temperature drops below
120°F the contacts close.
A condenser fan speed controller is standard on this unit. The speed controller temperature sensor is
installed in the airstream of the condenser. When the ambient temperature is above 95°F the condenser fan
will run at full speed. When the ambient temperature is between 85°F and 95°F the condenser fan will run
between maximum and minimum speed. When the ambient temperature is lower than 85°F the condenser
fan will cycle. In applications having frequent voluntary or involuntary power interruptions or heat load
fluctuations, a Compressor Short Cycle Protector is recommended to allow adequate time for the internal
pressure of the air conditioner to equalize before restarting.
When the Kooltronic Air Conditioner is properly sized it should operate constantly and maintain 75°F to
115°F enclosure temperature, depending on the ambient temperatures.
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. To avoid compressor damage do not tip the unit more than 45° from its
proper mounting position.
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 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. 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. 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.
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.
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_NA4C3P21R have been engineered to be installed easily.
These units utilize double layer gaskets. The first gasket layer is placed on the outside perimeter of the front panel
that is sealed against the customer enclosure. The second layer is placed on the two cutouts in the front panel.
The first gasket layer will allow a small amount of water between the two layers. The second gasket layer totally
protects an enclosure from ambient air, rain or hose down water. This gasket arrangement assures the integrity of
the closed loop system and is necessary to maintain the NEMA 4 rating.
Prior to mounting, refer to page 8 for the general arrangement drawing 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.
2. Attach the Mounting Plate to the enclosure using (3) 1/4-inch
stainless steel nuts, (3) sealing washers as a spacer and (3)
1/ - inch stainless steel mounting nuts. Sealing washers must be
4
placed against customer enclosure (see mounting drawing).
3. Place the air conditioner on the lift truck. Insert a 1-inch
(approximate) wooden block between the lift truck bottom and
the air conditioner bottom so that the angle between the unit
mounting panel and the air conditioner is about 15 degrees.

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 airflow 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, as
the condenser coil may become clogged with dust or lint from the air entering the face. A
unit with a clogged condenser coil will have the same reaction as one with a clogged filter.
A clean filter is the best protection.
1) Remove the two screws from the rear panel.
2) Remove the rear panel from the unit.
3) Remove the filter from the filter holder by moving it up and towards you.
4) After removal the filter should be flushed under warm water with the clean side up, driving
contaminants out from 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.
5) The filter may be sprayed with Kooltronic A-16 Filter Coating Adhesive to trap fine airborne
contaminates, or it may simply be dried and reinstalled. Recoating is recommended for the best
results.
6) Reinstall the filter.
7) Replace the rear panel and attach it to the unit with two screws.
11
B. Blowers
The design life of the blowers used in all Kooltronic Air Conditioners is substantially in excess of
20,000 hours. All Kooltronic condenser and evaporator blowers are equipped 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 the 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 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 Certified
EPA Technician that a refrigerant shortage does exist, the leak must be repaired. Then the unit
may be evacuated and recharged in the field by a Certified EPA Technician 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 the air conditioner from the 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."
