the iron internal surfaces and to ice formation in
cold weather. Both of these conditions can close
the operating clearances, causing the blower to fail
upon future start-up.
The following shutdown procedure minimizes
the risk of moisture condensation, corrosion, and
freezing.
Care must be taken to avoid overloading or
overheating.
1. Isolate the blower from the moist system
piping, allowing the blower to intake
atmospheric air.
2. Operate the blower under a slight load,
allowing the blower to heat within safe limits.
The heat generated by the blower will quickly
evaporate residual moisture.
3. For carpet cleaning applications, after the work
is completed, simply allow the blower to run
3 – 5 minutes with the suction hose and wand
attached. The suction hose and wand will
provide enough load to the blower to evaporate
the moisture quickly.
4. For extended shutdown, inject a small amount
of a light lubricating oil such as 3-in-One
®
* or
a spray lubricant such as WD-40
®
* into the
inlet of the blower just before shutdown. The
lubricant will provide an excellent protective
coating on the internal surfaces. If using
a spray lubricant, take care to prevent the
applicator tube from getting sucked into the
blower. The applicator tube will damage the
blower, likely to a degree where repair would
be required.

LONG TERM STORAGE
1. Spray the interior (lobes, housing, and end
plates) with rust preventative.
2. Apply a rust preventative grease to the drive
shaft.
3. Attach a desiccant bag to either 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.
4. 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.
5. If possible, rotate the drive shaft by hand at
least monthly in order to prevent seals from
setting in one position.
