V-Belt Replacement
Use this procedure to replace the V-belts on the Horizon 200 and
400 booths. In the Horizon 200 booth, the motor is mounted up on the side
of the fan shaft bearing supports.
WARNING:
Before performing the following procedures, shut off electrical
power at the system electrical panel. Lock and tag the disconnect switch.
1. Remove the final filters and access panels from the fan compartment.
2. See Figure 7-7. Loosen the nuts (5) so the motor can move on its
mounting.
3. Turn the tension screw (3) on the end of the motor mounting plate (4) to
move the motor toward the fan and loosen the V-belts (1).
4. Rotate the motor and roll the V-belts off the motor sheave (2) and fan
sheave (6).
5. Roll the new belts onto the sheaves and seat the V-sections in the
grooves. Use only properly sized, matched belts.
6. Turn the tension screw to move the motor away from the fan and tension
the belts.
7. Check the belt tension by pressing on the belts midway between the
sheaves. You should not be able to deflect the belts more than
13 − 19 mm (0.5 − 0.75 in.) or one belt diameter.
8. Tighten the nuts (5).
9. Install the access panels and final filters.
