PREVENTIVE MAINTENANCE

Cleaning the Condenser Coil

Failure to maintain a clean condenser coil can

initially cause high temperatures and excessive

run times. Continuous operation with dirty or

clogged condenser coils can result in compres-

sor failure. Neglecting the condenser coil

cleaning procedures will void all warranties and

repair or replacement costs associated with the

compressor.

CAUTION: To clean the condenser, never use

a high-pressure water wash, which

can damage electrical components

located at or near the condenser

coil.

Figure 2

Location of Condensing Coil

and Air Filter

The condenser coil is located and accessed at

the rear of the unit (see Figure 2). The condenser

coil requires regular cleaning and should be done

every 60 days. However, if large amounts of

dust and grease accumulate sooner, clean the

condenser coil every 30 days.

For light dust, use a soft, non-wire brush.

For heavier dust, use a vacuum or blow with

compressed air.

For heavy grease, use a degreasing agent made

specifically for condenser coils on refrigeration

units. Spray the degreasing agent on the coil

and then blow with compressed air. Never wash

with high-pressure water, which can damage

the electrical components located at or near the

condenser coil.

Door Gasket Maintenance

Door gaskets require regular cleaning to prevent

mold and mildew build up and to maintain

elasticity for proper seal function. Warm soapy

water is adequate for cleaning the gasket. Avoid

using full strength cleaning products, which can

cause the gasket to become brittle and result in

improper seal function. Never scrape or clean the

gasket with sharp tools or knives.
