MAINTENANCE
Warning:
Before you attend to any routine maintenance, make sure that the electrical power is disconnected.
- Avoid spilling any liquid on the thermostat
- Always allow for 1 to 2 minutes before activating different commands.
COIL CLEANING
Coil may be cleaned by removing and brushing between fins with a stiff wire brush. Brushing should be followed by
cleaning with vacuum cleaner. The coil may also be cleaned by using a high pressure air, if compressed air source is
available. It should be pointed out that if air filters are used and periodically cleaned, the coils will not be clogged up
prematurely.
DRAIN PIPE
Drain pipe should be checked before summer operation of unit. If it is clogged, steps should be taken to clear the debris
so that condensate will flow out easily. A standard pipe cleaner for 1/2" ID pipe may be used. Periodic checks of the drain
pipe should be taken during summer operation, as there is a possibility of it becoming clogged with dirt.
FILTER CLEANING
Remove access panel, slide filter out of filter rack, and clean as follows:
Tap filter on solid surface to dislodge heavy particles. Wash under stream of hot water. If filter has been put to exceptional
service, a mild solution of Sal-Soda, Tri-Sodium Phosphate or any other commercial solvent can be used. Set filter on
end with slots in frame down, which allows it to drain. Filters should dry thoroughly before reuse.
REPLACEMENT PARTS
When writing for replacement parts, refer to model number and serial number on the nameplate of the unit.
ROUTINE/PREVENTIVE MAINTENANCE
- Clean the thermostat box with a dry soft cloth.
- Remove the filter by a jet of air in the reverse return air direction.
- Inspect the condensate pipe for clogging.
