ECONOMIZER

Even with good filters properly in place, the economizer assembly will become dust laden after many months of use. The entire assembly should be inspected annually. If the assembly is heavily coated with dust, it can be brushed and cleaned with a vacuum. A common aerosol contact cleaner will help remove excess accumulation.

After the dust and debris is removed, a silicon based spray lubricant should be applied to each of the gears used to con- nect and ensure proper alignment of the damper blades.

Perform all maintenance operations on the damper assembly with power disconnected. Do not clean or lubricate with the unit in operation.

Excessive lubrication may accelerate the accu- mulation of dust.

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.

BLOWER SHAFT BEARING

Blower shaft bearings should be inspected on a monthly basis. At a minimum, the bearings should be relubricated every 6 months using a lithium-based grease (NLGI grade 2) recommended for ball bearing service.

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.

Damage can occur if the bearings are overlubri- cated. Use grease sparingly.

MOTORS

Outdoor fan motors are permanently lubricated and require no maintenance.

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

Indoor Blower Motor and Drive - The indoor blower motor fea- tures ball bearings that do not require periodic lubrication. Periodic lubrication of the motor and bearings can extend the life of components but is optional.

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.
