7.7 CLEANING STATION SUBSYSTEM
1. Solution tank: Clean the tank as required with product
water and a cloth.
6. Thoroughly clean seal cavity in bracket and pump
shaft with appropriate solvents or cleaners.
B. Reassembly:
1. If shaft was removed, install pump shaft onto motor
shaft while aligning setscrews of pump shaft with
key way of motor shaft. Ensure that all debris and
burrs are removed from motor shaft. Also, ensure that
slinger is aligned between the two setscrews of pump
shaft.
2. Place bracket on fi rm surface with seat cavity (pump
end) up. Place a small amount of vegetable oil on the
seat cup or O-Ring of seat. Place seat in seat cavity
with ceramic end up toward pump end. Be careful not
to scratch sealing surface of seat with sharp objects
or a leaking pump is the result. Gently tap seat into
place with a wooden dowel or plastic rod (1-1/8 inch
diameter) and to help insure seat is not damaged, use
a cloth or clean rag over dowel or rod).
3. Place bracket on motor end, align base in place.
Secure with 4 bolts.
Note: The longer 1 1/4 inch bolts are used
with base.
4. Pull out pump shaft as far as it will go toward volume
end and slightly snug one setscrew to hold shaft in
place.
5. Lubricate pump shaft with a few drops of vegetable
oil. Push seal in a rotating motion onto shaft evenly
with carbon face toward ceramic seat. Be careful not
to pull viton bellows from assembly. A tapered device
placed over pump shaft threads (5/8” maximum O.D.)
can simplify this operation.
6. Screw impeller onto shaft ensuring that the spring
retainer of seal does not slip between the shoulder
of the shaft and the impeller hub. Tighten impeller
securely and reinstall impeller locking screw and
washer. A screwdriver or fl at fi le wedged between
impeller vanes may be used as a tool.
7. Place gasket on bracket and install volume. Secure
with 8 volume bolts and tighten bolts.
8. Set impeller by moving shaft toward motor
approximately 0.010” - 0.015” (a screw driver
against the shoulder can be used). Slightly tighten
one setscrew of pump shaft to hold shaft in position.
Rotate shaft by hand to ensure impeller clears
volume. If impeller strikes volume, loosen setscrew
and move shaft back further, repeat and check. When
proper clearance between volume and impeller is
achieved tighten setscrews on pump shaft securely.
9. Jog the motor by manually tripping the product water
pump contactor to determine if rotation is free.
