6.The odor media pellets can be checked for remaining life by sending a sample to
an accredited test laboratory. Most major filter suppliers have access to such
service. Replace media if required. To replace the media remove the cells from
the KES unit. Open the side panel on each odor cell and pour out the used
media. Refill the cells with new media. Shake cells while filling to allow pellets to
settle evenly in the cell. Note: Do not allow odor media to come in contact with
water, as this will immediately render the pellets useless.
Fan Bearings
1.STY and FYC bearings are factory pre-lubricated lifetime sealed and require no
further lubrication.
2.SY and FY bearings are pre-lubricated and equipped with pressure grease fittings
for re-greasing.
3.Under normal service conditions grease after six months of operation.
Motor Bearings:
1.All motors leave the factory with bearings custom greased for many years of
service under most conditions.
2.Re-greasing of motors depends on the application and is best left to trained service
technicians.
3.Periodically check if motor is running hotter then normal.
Centrifugal Exhaust Fan:
1.Make sure the wheel rotates freely before startup.
2.Inspect and clean the wheel periodically.
3.If dirt is allowed to build up the wheel could become out of balance and cause
premature bearing wear.
4.A noisy fan is a typical sign of a fan out of balance.
V-Belt Drives:
1.ALWAYS KEEP SPARE SET OF BELTS. Periodically check the belt tension and
adjust if necessary.
2.Some slack should be left in the belt, typically 1/4" per foot of belt from the fan to
the motor sheave.
3.Always replace the complete set of belts to ensure even tension and wear. When
replacing belts loosen the motor mounts.
4.Do not force belts over sheaves.
