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
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 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.

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 compo-
nents.
Closed-Loop cooling seals the electronics enclosure from hostile elements in the environ-
ment.Two separate circulation systems are employed.The internal system cools and dehu-
midifies the air inside the cabinet, totally isolating the sensitive electronics and other com-
ponents 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.
Kooltronic Air Conditioners are designed to operate continuously in order to eliminate
compressor cycling, which shortens compressor life and causes line transients.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 applica-
tions having frequent voluntary or involuntary power interruptions, a Short Cycle
Protector is recommended to allow adequate time for the internal pressures of the
Air Conditioner to equalize before restarting.

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.
Kooltronic Air Conditioners are designed to operate continuously in order to eliminate
compressor cycling, which shortens compressor life and causes line transients.The cool
air discharge temperature is regulated by the capacity control (hot gas bypass) valve. In
applications subject to over-cooling, a Low Temperature Control (thermostat) should be
considered. In applications having frequent voluntary or involuntary power interruptions,
a Short Cycle Protector is recommended to allow adequate time for the internal
pressures of the Air Conditioner to equalize before restarting.
VI. Pre-Installation Testing
The Air Conditioner may be operated during receiving inspection without a heat load.
ON THERMOSTAT-EQUIPPED UNITS, IF THE COMPRESSOR AND CONDENSER BLOWER
(AMBIENT SIDE) FAIL TO OPERATE,THE THERMOSTAT MAY NEED ADJUSTMENT.
Adjust Thermostat setting downward until compressor and condenser blower start.
(Note factory setting first)
If unit is tested without heat load, be sure to reset Thermostat to factory setting prior
to installation and operation.
CAUTION
Refer to the identification label for proper electrical current requirements.Then connect
the power cord to a properly grounded and fused electrical supply.
Operate the Air Conditioner for approximately ten (10) minutes. During this period no
unusual noise or vibration should be evident. Both the condenser and evaporator
blowers should be delivering air through their respective discharge ports.The cool air
discharged should be less than 70° Fahrenheit when the room temperature is between
70° and 80° Fahrenheit. If the compressor and condenser blower (ambient side) fail to
operate on thermostat-equipped units, the thermostat may need adjustment.If any cover
plug is removed to adjust the unit, make certain to put the cover plug back in place to
maintain the integrity of the closed-loop airflow system.
NOTE: Before shipment all Kooltronic Air Conditioners are subjected to a cooling
performance test at the rated capacity.
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.

VII. Specific Model Data
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. 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 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 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. Attach overflow drain hose supplied to the drain exit in the side or bottom of the unit.This hose
must not be elevated above the exit port. Improper mounting will impede the flow of conden-
sate 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
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.
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.
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
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 peo-
ple only.
CAUTION
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".
12
Before opening the Air Conditioner, disconnect all power.
Refer to the data on the unit name plate which specifies the type of
refrigerant and the amount of charge in ounces.

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 service, we have compiled a
trouble-shooting chart to assist your service personnel. If additional assistance is
required contact Kooltronic at 609• 466-3400.

CONDENSATE EVAPORATOR KIT: This device
attaches to bottom of Air Conditioner. Condensate is col-
lected, vaporized and discharged to ambient.
COOLING EFFECT DETECTOR: A thermostat is
mounted inside the cabinet and attached to a sensor in
the warm air return. When the air temperature increases
to a set point, a signal is sent to a terminal block.
Requires user-installed wiring to a warning device.
EXCESS PRESSURE DETECTOR: Monitors head or
condensing pressure within the Air Conditioner. When the
pressure reaches an unsafe level a switch sends a signal
to the terminal block. Requires user-installed wiring to a
warning device.
LOW TEMPERATURE CONTROL: Recommended in
situations of extremely low ambient temperatures and/or
low internal loads. At a pre-set return air temperature, the
Thermostat shuts down the unit, except for the
evaporator blower, for continuous cabinet air circulation.
SHORT CYCLE PROTECTOR: Protects the compressor
from damage due to harmful short cycling after a power
interruption. Protector keeps compressor off for 5 to 6
minutes before resumption of operation.
WEATHER PROTECTION KIT: For outdoor installations
subject to invasion by rain, snow or windblown dirt,
special deflectors shield the condenser air inlet and
outlet ports.
