KOLDWAVE KOMPAC SERIES (KOOLETTE, KOMPAC, AND KING KOMPAC)
ABC’S OF TROUBLESHOOTING
A. Read this manual to determine installation,
electrical power, water pressure and flow
requirements necessary to allow the air conditioner
to perform at its maximum.
B. Refer to general description, wiring diagrams and
photographs to get an understanding of how the
unit functions.
C. Establish which part or parts controls the particular
operation. Parts can be tested by the “bypass
method”, “the light method”, or “the direct line
method”.
The “bypass method” would be used on switches,
thermostats, overloads, or any part that completes
an electrical circuit. A jumper wire is connected
across the terminals of the suspected part. If the
trouble is eliminated, the part shorted out is
defective and must be replaced.
Motors, compressors and pumps can be tested by
the “direct line method”. A line cord with a series
fuse is connected directly to the suspected part.
The unit under test is then proved inoperative.
The “light method” utilizes a light bulb in the line
cord, instead of the fuse as in #2. When this test is
applied and the light bulb lights to full brightness,
the part tested is shorted. No light indicates the
circuit is open.
PREVENTATIVE MAINTENANCE
Kompac Series units have been designed to give
maximum performance and reliability with minimum
maintenance. Maintenance of the system is
concentrated in three areas covered in the following
paragraphs.
Blower Motor
The only required maintenance to the blower motor is
to oil it every six months (every three months for King
Kompac models with SAE20 non-detergent oil. On
model K07D, remove the one piece front and top
cabinet panel to reach the motor oil ports. On models
K20-K26D, remove cabinet back panel to oil the motor.
Take off the front louvered panel on models K10-K16D
to gain access to fan motor oil ports.
