Maintenance
When returning a blower to the factory for
repair, under warranty, please note the factory
will not accept any unit that arrives without
authorization. Contact the Service Department
for return authorization.
LONG-TERM STORAGE
Any time the blower will be stored for an extended
period of time, make sure it is protected from
corrosion by following this procedure:
1. Spray the interior (lobes, housing, and end
plates) with rust preventative. Repeat as
conditions dictate and on an at least a yearly
basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a prominent tag stating that the
end covers are full of oil and must be drained
and re
¿
lled to proper levels before start-up.
4. Apply a rust-preventative grease to the drive
shaft.
5. Spray all exposed surfaces, including the inlet
and discharge
À
anges, with rust preventative.
6. Seal the inlet, discharge, and vent openings.
It is not recommended that the blower be set
in place, piped to the system, and allowed to
remain idle for a prolonged amount of time. If
any component is left open to the atmosphere,
the rust preventative will escape and lose its
effectiveness.
7. During storage, make sure the blower does not
experience excessive vibration.
8. Attach a desiccant bag to one of the covers to
prevent condensation from occurring inside the
blower. Make sure any desiccant bag (or bags)
is attached to the covers so that they will be
removed before start-up of the blower.
9. Store the blower in an air conditioned and
heated building if possible. If air conditioned
and heated storage is not possible, make
conditions as dry as possible.
10. If possible, rotate the drive shaft by hand at
least monthly to prevent seals from setting in
one position.
