  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.
