I. Introduction
Kooltronic Air Conditioners are designed to provide a cool, dehumidified environment for your electronic
components. There are models to fit virtually all sizes and shapes of electronics enclosures, in
capacities ranging from 1,000 to 30,000 BTU/H. Our "closed-loop" design also ensures that your
components will not be exposed to hot, dirty operating conditions.
This Manual provides you with the necessary general information for properly installing and operating
standard Kooltronic Air Conditioners. Technical data and mounting instructions are presented on pages
6 through 11.
2
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 packaging tears, dents, scratches, loose articles or evidence of oil are
signs of damage and should be noted on the Freight Bill. Shipments should be opened immediately 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 lying down or removed from the shrink wrapped or banded pallet 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, 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) 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 a suitable container (preferably original packaging if possible), with
adequate internal protective packaging, making sure shipment is marked and is kept in correct
upright position.
For local, controlled transportation, strap packaging 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.

V. Principles of Operation
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.
COOL AIR TO
ENCLOSURE
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
HEATED AIR
FROM
isolating the sensitive electronics and other components
CONDENSER
ENCLOSURE
OUTLET
from the environment. The external system uses
(Heated Ambient
Air Out)
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 hermeticallyCONDENSER
AIR INLET
sealed refrigeration system, utilizing either an air-cooled
(Ambient Air In)
CONDENSER
or water-cooled condenser heat exchanger. The warm air
OUTLET
(Heated Ambient
inside the enclosure is drawn through the evaporator coil
Air Out)
where it is cooled, dehumidified and returned.
Any enclosure moisture accumulated on the evaporator
coil is collected in the condensate tray and removed
CONDENSER
OUTLET
through the drain tube to the condensate evaporator.
(Heated Ambient
Air Out)
KAC4P3777R
Condensate evaporates in the condensate evaporator
and is 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 condenser coil, where it absorbs the heat and is then discharged
to the environment.
This unit is equipped with Cooling (Low Temperature) and Heating thermostats. The factory Cooling
thermostat setting is 92°F with a differential of 7°F. When the temperature inside of the enclosure rises
above 99°F the air conditioner will run in Cooling Mode. When the temperature inside of the enclosure
drops below 92°F the air conditioner will shut off. The factory Heater thermostat setting is 45°F with a
differential of 5°F. When the temperature inside of the enclosure drops below 40°F the air conditioner will
run in Heating Mode. When the temperature inside of the enclosure exceeds 45°F the air conditioner will
shut off. The Cooling and Heating thermostats are interlocked, so that the air conditioner cannot run in
Cooling and Heating Mode simultaneously. The Condenser Impeller is controlled by a pressure switch. At
medium ambient temperature below 75°F the Condenser Impeller will cycle. When the air conditioner
starts in Cooling Mode the Condenser Impeller will remain off for about four (4) to seven (7) minutes,
until the discharge refrigerant pressure builds up. The Cooling thermostat is equipped with a three (3)
minute time delay on start-up to prevent compressor short cycling.
5
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 65oF to allow the system to warm up.
2. Note that the factory Low Temperature Thermostat (compressor) setting is 92oF with a differential of 7oF (Cooling
Mode, Cut out at set point), and that the Heater Thermostat setting is 45oF with a differential of 5oF (Heating Mode,
Cut out at set point).
3. Refer to the identification label for proper electrical voltage and current requirements. Connect the power cord
from the rear of the unit to a properly grounded and fused electrical supply, leaving electrical power to the unit
turned off.
4. Plug the remote control 3 position connector into the unit receptacle labeled “Control.” Plug the remote control
power cord into the unit receptacle labeled “Thermostat Power.”
5. Turn the electrical power on.
6. Verify that the evaporator blower is running. (The remote control includes a compressor time delay. After operating
three (3) minutes the unit will run in cooling mode.)
7. Heat up the cooling thermostat sensor with a heat gun. When the cooling thermostat display temperature reaches
100oF the air conditioner should start. Keep the cooling thermostat temperature above 93oF.
8. After four (4) to seven (7) minutes the condenser impeller should start.
9. Operate the air conditioner for ten (10) minutes. During this period no unusual noise or vibration should be evident.
o
The condenser impeller could cycle during this period of time. The cool air discharge should be at least 15 F lower
than the ambient temperature.
NOTE:
Before shipment all Kooltronic Air Conditioners are subjected to a performance test.

VIII. Maintenance
Kooltronic Air-Cooled Air Conditioners require routine cleaning of the condenser coil (if necessary) and the air
filters (if they are supplied) to assure unimpeded airflow through the condenser heat exchanger. It is not possible to
recommend specific condenser coil or filter cleaning intervals, since the level and the nature of airborne particulate
matter differs widely with each installation. It is generally sufficient to clean the condenser coil and/or the aluminum
mesh filter when the outer surfaces appear covered with a thin layer of dust, lint or other foreign matter. The
condenser coil can be washed or blown out with air, depending on the foreign matter involved (see below - Filter
and condenser coil service). The aluminum mesh filter can be washed with warm water. Appropriate disposable
replacement filters are available from Kooltronic.
If routine condenser coil or filter service is neglected or delayed, the air conditioner will not perform at its design
capacity. The first indication of an excessively clogged condenser coil or air filter 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 and condenser coil service
If an optional filter is installed on externally mounted air conditioners (filter should not be used for internal
mounted air conditioner), the rear panel must be removed in order to clean the filters. After removal, the
filters should be flushed under warm running water with clean side up. If the accumulated dirt is oily,
washing in a detergent bath is recommended, followed by a warm water wash as above.
If an optional filter is not used for an externally and/or internally mounted air conditioner, the exposed
condenser coil must be cleaned by pressurized air or pressurized cleaning solution. Dirty liquid will be
removed through the condenser coil drain pan.
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.
14
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".
.IX. Trouble-Shooting
Each Kooltronic Air Conditioner is engineered for performance and built for reliability. They are designed to
require only routine maintenance. 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 (609) 466-3400.
