its deterioration. To re-place the pre-filter
(6), introduce it gently, until it is in its original
position. Correctly place the seal (3) of
the cover (2) and grease with vaseline.
The transparente cover (2) must be
cleaned with water and neutral soap;
"do not use detergents". Do not place
the filter (6) in chemicals.
Please remember that changes in position
of the selection valve will be made at all
times with the motor switched off.
7.2.
ATTENTION
If the pump is switched off for long periods of
time, should there be a danger of frost, the
pump casing (7) should be emptied, by
loosening the two emptying outlets (9)
along with their O-ring seals (10).
Before starting the pump, replace the outlets
(9) and their O-ring seals (10). Fill the pump
chamber with water and check with a
screwdriver that the motor is not jammed. If
the shaft has seized up, call a qualified technician.
In the event of the motor flooding, do
not try to start it; call an electrician to
dismount the motor in order to dry it.
8. DISMOUNTING
8.1.
ATTENTION
Before performing any operation, all
valves must be in the "off" position;
having checked this:
- Disconnect the general electricity switch
and the differential switch (this must be
done by an authorised specialist).
- Loosen and remove the supply cables on
the bushings box (29) (fig. 6, page 41).
- Release the aspiration and return
sleeves.
- Empty the pump.
8.2.
ATTENTION
In order to dismount and assemble the
electropump, please see the detail drawing.
In order to remove the motor from the hydraulic
casing, remove the four screws (22) and lever
with two screwdrivers, one opposite the other.
In order to dismount the impeller (17), separate
the diffuser (16) and its junction (15), loosen
the ventilator cover (42) and remove the
ventilator; block the motor shaft with the aid of
a clamp, while rotating the impeller (17)
anticlockwise with a number 14 pipe wrench,
thus releasing the shaft. The mobile part of
the retainer (18) comes out with the header.
9. ASSEMBLY
ATTENTION
"All parts to be assembled must be
clean and in perfect condition for use"
In order to assemble the pump:
- Assemble the mechanical seal (18/19), (fig.6,
page 41), assemble the rotary part of the
seal (18) above the back flange of the
impeller (17) by pressing until this falls into
the space; the retainer will have been
lubricated with water beforehand.
- Assemble the impeller (17) on the shaft (30)
affixing it with Loctite or similar in the threaded
metal insert. In this way, the two grooves of
the mechanical seal are joined (18/19).
- At the junction of the pump with the motor, it
must be borne in mind that the diffuser
flange (16), and all other connections (15
and 20), must fit into the correct space.
