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.
