NOTICE

Do not over-tension belts. Exces- sive belt tension will reduce fan and motor bearing life, accelerate belt wear, and possibly cause shaft failure.

To adjust belt tension refer to Figure M- MP-6 and perform the following procedure:

1. Loosen bolts A, B, and E on both sides of the sliding motor base. See Figure M- MP-7.

2. Loosen nuts C and D (as required for motor horsepower) to slide the motor on its mounting plate in the proper direction to tension or relieve tension on

the belt.	Figure O-M-5. Fan assembly.
the belt.
3. Adjust nuts A-D and bolt E. Do not
stretch the belts over the sheaves.
4. Retighten all nuts and bolts.
5.Verify tension is adjusted properly.
Recommended belt tension range values
are on the unit fan scroll.To access the
fan scroll, face the right-hand side of the
unit and remove the top left panel. The
belt tension label is on the top right-hand
corner of the fan scroll. See Figures O-M-
8 and O-M-9.
The correct operation tension for aV-belt
drive is the lowest tension at which the
belt will not slip under the peak load
conditions. It may be necessary to
increase the tension of some drives to
reduce flopping or excessive startup
squealing.
