Routine Maintenance

These items should be part of a routine maintenance program, to be checked every month or two, until a specific schedule for each can be identified for this installation:

Quarterly Inspection (and 30 days after initial start)

S Return air filter replacement

S Outdoor hood inlet filters cleaned S Belt tension checked

S Belt condition checked

S Pulley alignment checked

S Fan shaft bearing locking collar tightness checked S Condenser coil cleanliness checked

S Condensate drain checked

Seasonal Maintenance

These items should be checked at the beginning of each season (or more often if local conditions and usage patterns dictate):

Air Conditioning

S Condenser fan motor mounting bolts tightness S Compressor mounting bolts

S Condenser fan blade positioning

S Control box cleanliness and wiring condition S Wire terminal tightness

S Refrigerant charge level S Evaporator coil cleaning

S Evaporator blower motor amperage

Heating

S Heat exchanger flue passageways cleanliness S Gas burner condition

S Gas manifold pressure S Heating temperature rise

Economizer or Outside Air Damper

S Inlet filters condition

S Check damper travel (economizer)

S Check gear and dampers for debris and dirt

Air Filters and Screens

Each unit is equipped with return air filters. If the unit has an economizer, it will also have an outside air screen. If a manual outside air damper is added, an inlet air screen will also be present.

Each of these filters and screens will need to be periodically replaced or cleaned.

Return Air Filters

Return air filters are disposable fiberglass media type. Access to the filters is through the small lift-out panel located on the rear side of the unit, above the evaporator/return air access panel. (See Fig. 1.)

To remove the filters:

1.Grasp the bottom flange of the upper panel.

2.Lift up and swing the bottom out until the panel dis- engages and pulls out.

3.Reach inside and extract the filters from the filter rack.

4.Replace these filters as required with similar replace- ment filters of same size.

To re-install the access panel:

1.Slide the top of the panel up under the unit top panel.

2.Slide the bottom into the side channels.

3.Push the bottom flange down until it contacts the top of the lower panel (or economizer top).

IMPORTANT: DO NOT OPERATE THE UNIT WITHOUT THESE FILTERS!

Outside Air Hood

Outside air hood inlet screens are permanent aluminum-mesh type filters. Check these for cleanliness. Remove the screens when cleaning is required. Clean by washing with hot low-pressure water and soft detergent and replace all screens before restarting the unit. Observe the flow direction arrows on the side of each filter frame.

Economizer Inlet Air Screen

This air screen is retained by spring clips under the top edge of the hood. (See Fig. 3.)
