PREVENTIVE MAINTENANCE

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 infi ltrate 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.
Notes: 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
fl owing 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 fi lter.
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 fi lters. Inspect twice a year to avoid the
possibility of overfl ow.

CAUTION
Blower Motors
Blower motors on most air handlers are equipped with sealed
ball bearings and require no periodic oiling.
Hot Water Generator Coil
See Water Coil Maintenance section above.
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 clean. Care must be taken not to
damage the aluminum fi ns while cleaning.
