GENERAL MAINTENANCE
Visit
and click on “Tools & Resources” for more detailed
maintenance information.
As with any equipment or machinery, a maintenance program should be implemented.
Equipment maintenance should include the following:
Check filters and clean or replace as needed.
Check burner.
Check belts, belt tension and sheave alignment. (Do not over tension.)
Confirm smooth operation of dampers.
Lube bearings.
Check all hardware (bearings, etc.) for tightness.
Check settings for all controls.
Check duct connections for leaks.
Check piping for leaks.
Inspect heating or cooling coils, on a monthly basis, and clean if necessary.
Clean condensate traps and replenish drain pan with anti-microbial treatment
(winterize traps seasonally).
Re-caulk seams if needed.
Go through complete start-up procedure (once per year).
FILTERS
Dirty or clogged filters will restrict air flow which in turn affects the equipment performance.
Therefore, it is necessary to check filters on a regular basis. Several standard filter types are
available including 2" pleated 30% efficient, 2" disposable fiberglass, 2" linked panel, and 1" or 2"
cleanable filters.
Cleanable filters should be removed from the filter rack and sprayed with a low pressure water.
Always spray these filters in the opposite direction to air flow and apply new coating to filters when
dry.
Note that cleanable filters alone may not adequately protect a coil from dust and dirt
accumulation.
Filters in an unheated outdoor airstream can “freeze-up” when the humidity is high (foggy)
and temperatures are near freezing.
Method of Prevention:
Install pre-filters in the outdoor airstream that can be removed during such weather.
BURNER
Refer to Heatco instruction manual for specific instructions on how to care for the indirect fired
burner and heat exchanger.
