MAINTENANCE
1. Filter changes or cleanings are required at regular
intervals. The time period between lter changes
will depend upon type of environment the
equipment is used in. In a single family home, that is
not under construction, changing or cleaning the
lter every 60 days is sufcient. In other applications
such as motels, where daily vacuuming produces a
large amount of lint, lter changes may be need to
be as frequent as biweekly.
Equipment should never be used during
construction due to likelihood of wall board dust
accumulation in the air coil of the equipment
which permanently affects the performance
and may shorten the life of the equipment.
2. An annual “checkup” is recommended by a licensed
refrigeration mechanic. Recording the performance
measurements of volts, amps, and water
temperature differences (both heating and cooling)
is recommended. This data should be compared to
the information on the unit’s data plate and the data
taken at the original startup of the equipment.
3. Lubrication of the blower motor is not
required, however may be performed on some
motors to extend motor life. Use SAE-20
non-detergent electric motor oil.
4. The condensate drain should be checked
annually by cleaning and ushing to insure
proper drainage.
5. Periodic lockouts almost always are caused by air
or water ow problems. The lockout (shutdown)
of the unit is a normal protective measure in the
design of the equipment. If continual lockouts
occur call a mechanic immediately and have them
check for: water ow problems, water
temperature problems, air ow problems or air
temperature problems. Use of the pressure and
temperature charts for the unit may be required
to properly determine the cause.
