AIR FILTERS

All units contain four filters. The filter racks on these units will receive either 1" or 2" filters. Filters can also be installed in the building at a suitable return air location if an economizer or outside air accessory is not used. Filters must always be used. They should be inspected once a month and thor- oughly cleaned or replaced if it appears they are beginning to accumulate excessive dirt.

To install the filters, remove the filter access panel as shown in Figure 4.

NOTE: Filters must be installed with “Air Flow” arrows point- ing inward -- toward the indoor coil. In the event the spacers in the filter section are removed, they must be reinstalled in their original position.

Slide filters all the way into the filter racks provided. When more than one filter in a filter rack is required, they must butt each other when sliding into position. Replace the filter access panel.

BLOWER ASSEMBLY

Even with good filters properly in place, blower wheels and motors will become dust laden after many months of opera- tion. The entire blower assembly should be inspected annu- ally. If the motor and wheel are heavily coated with dust, they can be brushed and cleaned with a vacuum cleaner.

These units are supplied with blower shaft bearings that do not require maintenance but may be lubricated

if desired. Every three years, using a low pressure grease gun, pump grease into the bearing grease fitting until grease just begins to show at the seals. Do not over lubricate. Use any lithium base grease recommended for ball bearing ser- vice.

Perform all maintenance operations on the blower motor with electric power disconnected from the unit. Do not attempt to lubricate bearings with the unit in operation.

MOTORS

Outdoor fan motors are permanently lubricated and require no maintenance.

Ventor motor is factory lubricated for an estimated 10 year life.
