Maintenance
1. Normal maintenance on all conditioners is generally lim-
ited to filter changes and fan motor lubrication. Lubrica-
tion of the fan motor should be performed in accordance
with the instruction label on the conditioner. Be sure to
use non-detergent electric motor oil.
2. Filter changes are required at regular intervals. The time
period between changes will depend upon the project
requirements. Some applications such as motels produce
a lot of lint from carpeting and linen changes, and will
require more frequent filter changes. It is suggested that
the filter be checked at 60-day intervals for the first year
until experience is acquired. If light cannot be seen through
the filter when held up to sunlight or a bright light, it should
be changed. A more critical standard may be desirable.
3. The condensate drain pan should be checked annually
and cleaned and flushed as required.
4. Recording of performance measurements of volts, amps,
and water temperature differences
(both heating and
cooling)
is recommended. A comparison of logged data
with start-up and other annual data is useful as an indica-
tor of general equipment condition.
5. Periodic lockouts almost always are caused by air or
water problems. The lockout
(shutdown)
of the conditioner
is a normal protective result. Check for dirt in the water
system, water flow rates, water temperatures. If the lockout
occurs in the morning following a return from night set-
back, entering air below machine limits may be the cause.
