Cleaning Wheel Segments; Wheel Belt / Wheel Bearings - Greenheck APEX-200 Installation, Operation & Maintenance Manual

CLEANING ENERGY RECOVERY WHEEL SEGMENTS
If the wheel appears excessively dirty, it should be cleaned to ensure maximum operating efficiency. Only
excessive buildup of foreign material needs to be removed. DISCOLORATION AND STAINING OF ENERGY
RECOVERY WHEEL DOES NOT AFFECT ITS PERFORMANCE.
Thoroughly spray wheel matrix with household cleaner such as Fantastic ™ or equivalent. Gently rinse with
warm water and using a soft brush remove any heavier accumulation. A detergent/water solution can also be
used. Avoid aggressive organic solvents, such as acetone. The energy recovery wheel segments can be soaked
in the above solution overnight for stubborn dirt or accumulation.
After cleaning is complete, shake the excess water from the wheel or segments. Dry wheel or segments before
placing them back into the cassette. Place wheel or segments back into cassette by reversing removal
procedures.
** DO NOT CLEAN ENERGY RECOVERY WHEEL SEGMENTS WITH WATER IN EXCESS OF 140°F
** DO NOT DRY ENERGY RECOVERY WHEEL SEGMENTS IN AIR IN EXCESS OF 140°F.
Energy Recovery Wheel Belt
Inspect belts each time filters are replaced. Belts that look
chewed up or are leaving belt dust near the motor pulley
may indicate a problem with the wheel. Be sure to inspect
wheel for smooth and unrestricted rotation. If a belt
requires replacement, contact the local Greenheck
representative. Instructions for replacement will ship with
the new belt.
