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.
This Air Conditioner is 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
nameplate for the corresponding voltage. Do not exceed the maximum fuse size found on the nameplate.

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.

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.

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 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
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 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 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 illustrations below).

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.

The crankcase compressor heater allows the unit to start with an ambient temperature of 0

o

F. In applications having

frequent voluntary heat load fluctuations, 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

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 nameplate 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. Elevate the unit approximately 3" above the floor to ensure proper evaporator airflow. Do not block
evaporator air inlet on bottom of unit.

4. Note the factory thermostat setting which is 75

o

F.

5. Turn the electrical power on.

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

7. Verify that the condenser blower or fan is running. Note: The start of the condenser fan or blower will
be delayed until the system pressures rise.

8. 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.

9. Turn off the electrical power and disconnect the air conditioner from the power source.

10. 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.

The temperature of the returning air to the air conditioner is displayed on the exterior

panel of the unit. This is considered the maximum temperature within the enclosure

and not the temperature of the air supplied to the enclosure.

When the Kooltronic Air Conditioner is properly sized it should operate constantly and maintain 75oF to 115oF
enclosure temperatures, depending on the ambient temperatures.

IMPORTANT NOTE

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.

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

.

• Top-Mounted Air Conditioners for external top installation contain weld-nuts.

• Refer to Figure 1 above for the location of all mounting holes and cutouts.

• Make sure the cutouts don't interfere with components inside your cabinet.

• Proper alignment of all air inlets and outlets is essential for optimum performance of the Air

Conditioner.

• All externally-mounted Air Conditioners must be fully gasketed to ensure proper sealing. This seal is

necessary to maintain the integrity of the closed loop system. See Gasket Placement, Figure 2, above.

• Use all existing mounting holes to insure stability and a tight seal.

• High strength mounting screws are recommended.

• The external drain hose must not be elevated above the exit port. Improper mounting will impede the

flow of condensate and may cause internal malfunctions.

CAUTION

VIII. Maintenance

Kooltronic Air-Cooled Air Conditioners require routine cleaning of the condenser coil (if necessary) and the
air filters 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 blown out with air, or washed, depending on the foreign matter involved. Disconnect
power and remove air conditioner from cabinet before using liquids to clean the unit. (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

Kooltronic RT Top Mount Air Conditioners feature an easily removable inlet filter to facilitate
necessary cleaning. To access the filter, loosen the torx screws and remove the front grille. Push the
filter upward and pull the bottom edge forward to remove. 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. To reinstall the filter, insert the filter
into the filter holder and push the filter back into position. Reinstall the front grille using the torx
screws.

The condenser coil must be cleaned using pressurized air. If liquid cleaning solutions are used, it is
necessary that the air conditioner be removed from the cabinet to avoid liquids draining into the
electronics. Disconnect power before performing this type of operation.

CAUTION

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 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.

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

CAUTION

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 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

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".

Before opening the air conditioner, disconnect all power.

Refer to the data on the unit nameplate which specifies the type of

refrigerant and the amount of charge in ounces.
