f. Reinstall the wire filter retainer in the holes provided on the pad frame.
g. For evaporative cooling units, presoak the pads (already reassembled in the frame) with
water thoroughly for several minutes before reinstalling. This soaking conditions the surface
and the fibers of the pads, increasing water absorbability and filter performance in the
evaporative cooling process.
h. Correct belt adjustment is important as it cuts power consumption and prolongs the life of
the belt and motor.
i. When adjusting the belt tension, loosen the four motor mounting bolts and adjust the motor
until the belt can be deflected 1/2" to 3/4" for each foot of belt between the pulley and sheave.
WARNING:
Never tighten the belt by adjusting the motor sheave.
j. The blower motor, blower shaft bearings and recirculating pump on evaporative cooling units,
should be oiled twice a year with SAE 20 weight oil.
