6. Maintenance

Clean the filter inserted in the bathtub suction
opening at regular intervals.
The pump does not require servicing except for
disassembly for cleaning and removal of any
obstruction from inner parts and the draining hole
when, with use and in the course of time, perfor-
mance or self-draining capacity are found to be
reduced.
Avoid cleaning an installed pump by hosing down
directly with jets of water without protection
panels on the bathtub.
Disconnect electrical power be-
fore any servicing operation and
make sure the pump cannot be
accidentally switched on.
7. Dismantling
For dismantling and re-assembly see construction
in the cross-section drawing (page 11).
Remove the motor assembly with the lantern
bracket (32.00) from the pump casing (14.00),
after removing the screws (14.24), the nuts
(14.28) and the washers (14.29), levering them
out with two screwsdrivers in diametrically oppo-
sed positions.
To remove the impeller (28.00) insert a large
straight-blade screwdriver in the slot on the shaft
(78.00) at the ventilation end. Grip the impeller
with one hand and unscrew it, turning the shaft
counter-clockwise and twisting with both
hands (fig. 3a).

If it is not possible to hold or move the shaft with
the screwdriver, remove the fan cover (90.00) and
motor fan (88.00) and unscrew the impeller by
gripping the shaft with a suitable wrench.
With the impeller the rotating part of the mechani-
cal seal (36.00) will remove.

8. Re-assembly
To replace the mechanical seal (36.00) fit the
rotating part over the impeller hub (28.00) and
push the spring right down as far as the front
shoulder. In this way, correct spring compression
will be ensured in subsequent assembly.
Lubricate the seal with water and align the
impeller on the motor shaft.
Grip the impeller with one hand and turn the
shaft with a screwdriver in the clockwise
direction until tight.
With this operation the front surfaces of the
mechanical seal come into contact without rub-
bing against each other during tightening.
Clean the O-ring (14.20) and seal surfaces with
water.
When replacing the motor assembly
with the impeller, be careful to insert
t h e l o c a t i n g l u g i n s i d e t h e p u m p
casing (14.00) into the locating slot on
the diffuser cover (27.00).
