Maintenance Guidelines

The motor and blower bearings are permanently lubricated and should not require  
maintenance. The evaporator fans are belt driven. The drive belts should be routinely  
examined for wear and correct tension. An incorrectly tensioned belt can cause bearing or 
wear damage.

The belts can be tensioned by loosening the 4 bolts holding the motor to the motor mount. 
Once the motor mount bolts are loose, adjust the belts by tightening or loosening the two 
¾-in. adjusting bolts on the bottom of the motor mount bracket. Re-tighten the 4 bolts  
holding the motor to the motor mount.

A properly tensioned belt has approximately 1 in. to 1½ in. movement when both legs of the 
belt are pressed in midway between the pulley and the sheave.

Each unit is provided with replaceable filters that are installed in the evaporator return air  
section. The return air grill must be removed to gain access to the filters. Check filters  
periodically to verify that the filters are clean. Dirty filters will severely reduce the  
performance of the machine.

HAZARDOUS VOLTAGE!

DISCONNECT ALL ELECTRICAL POWER BEFORE SERVICING.

Follow proper procedures to ensure that the power cannot be inadvertently turned on. 
Failure to disconnect power before servicing can result in serious injury or death.
