ENERGY RECOVERY WHEEL (AR-DE MODELS ONLY)
Wheel Belt Replacement
1. Confirm that the model number on the belt replacement kit
matches the model number on the energy recovery wheel cas-
sette label. Remove the old belt from cassette.
2. Uncoil new belt as appropriate to minimize twisting when feeding
the belt around wheel rim.
3. At a location near the pulley, tape the hook end of the link to the
wheel rim with the narrow face of the V-belt positioned against
rim.
4. Rotate the wheel clockwise while feeding the belt onto the wheel rim.
until the taped end returns to the location of the pulley.
5. Remove the tape, and join the links with the belt positioned around the wheel rim.
6. Rotate the wheel clockwise to position the linked ends approximately 180° from the location
of the pulley.
To avoid releasing of the segment latch,
7. At the location of the pulley, insert the right angle red belt retainer between the rotatable
segment retainer latch and the wheel rim at the left side of a spoke.
8. Rotate the wheel counterclockwise to position the red belt retainer close to the wheel bearing
beam.
9. Create slack in the belt by removing it from the rim between the location of the pulley and the
red belt retainer, and then place the belt over pulley.
10. Rotate the wheel clockwise until the belt is fully stretched around the wheel rim and the
pulley.
11. Remove the red belt retainer and rotate the wheel clockwise a minimum of two (2) full rota-
tions (sixteen [16] spokes) while verifying by observation and touch that the belt is not twisted
on wheel rim or where it enters the pulley. If a metallic "click" is heard when link rotates past
the wheel bearing beam, see note below.
Pile seal brackets are fixed with a single screw to the cassette frame
near the ends of the wheel bearing beam. Because the height of the belt
link is slightly higher than that of the urethane belt, a metal click (a rare
interference) may occur when it passes the seal bracket. If this occurs,
remove the interfering bracket(s). No measurable change of perfor-
mance will occur.
