Preventive Maintenance

Replacement Procedures

Water Coil Maintenance

1. Keep all air out of the water. An open loop system should

be checked to ensure that the well head is not allowing

air to infiltrate the water line. Lines should always be

airtight.

2. Keep the system under pressure at all times. It is

recommended in open loop systems that the water

control valve be placed in the discharge line to prevent

loss of pressure during off cycles. Closed loop systems

must have positive static pressure.

NOTE: On open loop systems, if the installation is in an area

with a known high mineral content (125 PPM or greater) in

the water, it is best to establish with the owner a periodic

maintenance schedule so the coil can be checked regularly.

Should periodic coil cleaning be necessary, use standard

coil cleaning procedures which are compatible with either

the cupronickel or copper water lines. Generally, the more

water flowing through the unit the less chance for scaling.

Other Maintenance

Filters

Filters must be clean to obtain maximum performance.

They should be inspected monthly under normal operating

conditions and be replaced when necessary. Units should

never be operated without a filter.

Condensate Drain

In areas where airborne bacteria produce a slime in the

drain pan, it may be necessary to treat chemically to

minimize the problem. The condensate drain can pick up lint

and dirt, especially with dirty filters. Inspect twice a year to

avoid the possibility of overflow.

Blower Motors

Blower motors are equipped with sealed ball bearings and

require no periodic oiling.

Air Coil

The air coil must be cleaned to obtain maximum

performance. Check once a year under normal operating

conditions and, if dirty, brush or vacuum (with a brush

attachment) clean. Care must be taken not to damage the

aluminum fins while cleaning.
