Figure 23 Hub Assembly W/Ball Bearings - Bard I-TEC I30A1D Installation Instructions Manual

ANNUAL MAINTENANCE
1. Inspect and conduct the same procedures as
outlined under Quarterly Maintenance.
2. To maintain peak latent (moisture) removal capac-
ity, it is recommended that the energy recovery
wheels be sprayed with a diluted nonacid based
evaporator coil cleaner or alkaline detergent
solution such as 409.
NOTE: Do not use acid based cleaners, aromatic
solvents, temperatures in excess of 170° F or
steam. Damage to the wheel may result.
Do not disassemble and immerse the entire heat
wheel in a soaking solution, as bearing and
other damage may result.

3. Rinse wheel thoroughly after application of the
cleaning solution, and allow to drain before
reinstalling.
4. No re-lubrication is required to heat wheel bearings
of the drive motor, or to the intake and exhaust
blower motors.
5. If any belt chirping or squealing noise is present,
apply a small amount of LPS-1 or equivalent dry
film lubricant to the belt.
