Preventive Maintenance
Kompac Series units have been designed to
give maximum performance and reliability
with minimum maintenance. Maintenance of
the system is concentrated in four areas
covered in the following paragraphs.
1. Blower Motor:
On model K07D, remove the one-piece front
and top cabinet panel to reach the motor. On
models K23-K26D, remove cabinet front
and back panel to reach the motor. Take off
the front louvered panel on models K10-
K16D to gain access to fan motor.
Blower Motor Maintenance:
Caution: Always disconnect power source
before working on or near a motor or its
connected load.
Motor may require periodic cleaning to
prevent the possibility of overheating due to
an accumulation of dust and dirt on the
windings or on the motor exterior.
2. Condensate Pump
Caution: Always disconnect power source
before working on or near the pump.
Pump Maintenance:
Do not touch or clean the sensor device with
sharp objects or tools. The sensor element is
fragile so handle with care. Replace pump if
damaged in any way. If servicing, clean
carefully with a soft brush cloth or under a
slow running tap. Rinse out tray thoroughly.
Do not use solvent based cleaning agents.
Only mild detergents may be used, but rinse
thoroughly before refitting.
Do not use if the pump or its cable is
damaged in any way. Protect cable and
tubing from sharp edges.
3. Coils and Related Items:
Coil Maintenance:
Coil surfaces must be kept clean of dirt and
lint in order to operate at rated efficiency.
Coils should be inspected on a regular basis
and cleaned as required.
CAUTION: solutions used to clean coils
must not be corrosive to metals or
materials used in the manufacture of this
equipment. If cleaning solutions are
applied through means of high pressure
spray, care must be taken to avoid
damaging coil fins and water tube
condenser.
Condensate drain pan and drain system must
be periodically flushed.
4. Filter
The life of a filter depends entirely on its
environment and use. It is recommended
that the filter be inspected on a regular basis
every five to six weeks. A clogged filter
will cause the unit to operate at greatly
reduced efficiency. Pulling filter end cap at
bottom of filter, slightly lifting up and
pulling out can easily remove washable
aluminum air filters located behind the front
panel. The filter must be washed
periodically as needed this may be done as
follows:
1. Soak in solution of warm water and
detergent for 15 minutes.
2. Rinse in clean hot water, and shake
excess moisture from filter.
3. Spray one side of filter with light
film of oil.
