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 v ibration, crushing, etc. Therefore, a thorough inspection should be
done upon receipt of all shipments. Any car ton 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 Kool troni c 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 cer tain 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

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 par t 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.

3

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.

V. Principles of Operation

Kooltronic Air Conditioners are required when the equipment operating temperature m ust be k ept 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 retur ned.

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 fluctuations, an optional Compressor Short Cycle Protector is recommended.

VI. Pre-Installation T esting

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 particularly 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 ther mostat to its maximum setting.

5. If your unit is equipped with an on-off switch, move it to the on position.

6. Turn electr ical power on.

7. Verify that the evaporator blower or fan is running.

8. Adjust the ther mostat 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 blo w er 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 (10) minutes. Dur ing 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 pow er
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.

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.

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.

CAUTION

Before opening the Air Conditioner, disconnect all power.

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.

Refer to the data on the unit name plate which specifies the type of

E. Relocation

If your Kooltronic Air Conditioner has to be moved to another location by truck,
the following precautions should be taken:
