The supply will have neutral and earth wires.
l
The mains voltage must correspond to that shown on the nameplate rating
l
for the equipment.
The earth wire to be used must be sufficient to take, without deterioration,
l
the current absorbed by the equipment (see nameplate).
The mains earth wire will be connected electrically to all metal parts of the
l
equipment which should not be under current, but which could accidentally
be affected by the same and which are accessible to persons (see figs. 2).
It is obligatory to install a protection and operation switchboard which will
contain all necessary and recommended elements. In general terms, it will
contain:
a. General cut-off or unipolar switch.
b. Short-circuit and overload protection devices for motors.
c. 30mA differential high sensitivity switch.
d. Others for monitoring and control.
The electrical characteristics of the protection devices and their regulation will
comply with those for the motors to be protected and with the service condi-
tions envisaged for these, and the instructions given by the manufacturer must
be followed (see nameplate).
In the case of equipment with triphase motors, the motor winding intercon-
l
nection bridges, must be suitably positioned (see figs. 2).
Conductor inlets and outlets at the bushing box will have stuffings to ensure
l
the absence of damp and dirt, and will therefore have a sealed casing.
Conductors will have suitable terminals for connection to the bushings.

6. STARTING
Before connecting the equipment to the mains, the following operations
will be carried out:
Check that the electrical conditions are correct.
l
Manually check that the motor pump is not jammed.
l
6.1. Pump priming. ATTENTION. "Avoid blind functioning of the electro-
pump". With the pump in the suction position (above the water level of the
swimming pool), before starting, remove the prefilter cover (66) (fig. 3) and
slowly fill with clean water up to the level of the aspiration nozzle. Close the
cover (66) again and take care that it is hermetically closed.
ATTENTION. With the pump below the swimming pool water level, al-
ways with the cover (66) hermetically closed, fill the pump by slowly ope-
ning the aspiration cut-off valve, with the header valve in the open position.
6.2. ATTENTION. The pump must not be started without the lumps and hair
filter (item 64) (fig. 3) since this could cause obstruction and would block the
system.
6.3. Direction of rotation. ATTENTION. Ensure that the motor shaft turns fre-
ely; do not start the pump if it is blocked. For this purpose, electropumps have
a groove at the end of the shaft, on the ventilator side, which permits it to be
turned manually using a screwdriver (fig. 1).
In triphase motors, the impeller (55) can be unscrewed if the motors starts in
the opposite direction.
Counter-rotation can even damage the mechanical seal. Start the motor for a
few seconds and check that the direction of rotation coincides with that indi-
cated by the arrow on the ventilator cover.
Should this not be the case, it is absolutely necessary to advise the authorised
installer (invert the connections between two phases).
6.4. ATTENTION.
Check that the motor does not exceed the amperage indicated on the name-
plate rating (120) (fig. 3); otherwise, regulate using the header valve.
7. MAINTENANCE / CONSERVATION
Before touching, disconnect the electricity supply.
7.1. ATTENTION. Regularly check and clean the basket (64).
To remove the basket, place the valves, and all other valves, in the "off"
position. Loosen the cover (66) of the prefilter (100), remove the basket
(64) and clean it under running water, "do not strike" to avoid its deterio-
ration. To re-place the basket (64), introduce it gently, untill it is in its ori-
ginal position. Correctly place the joint (65) of the cover (66) and grease
with vaseline.
Do not place the basket (64) in chemicals. Please remember that changes
in position of the valves 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 dan-
ger of frost, the pump casing (62) should be emptied, by losening the plug
(69)/(103) along with their O-ring seals. Before starting the pump, replace
the plug (69)/(103) and their O-ring seals. Fill the prefilter (100) with wa-
ter 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 floo-
ding, do not try to start it; call an electrician to dismount the motor in or-
der 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
l
must be done by an authorised specialist).
Loosen and remove the supply cables on the connection box (26) (fig. 3).
l
Release the aspiration and impulsion sleeves.
l
Empty the pump.
l
8.2. ATTENTION
In order to dismount and assemble the electropump, please see the detail
drawing. (Fig. 3). In order to remove the motor from the hydraulic casing
(62), remove the screws (63,53,107) and lever so as to separate one part
from the other one.
In order to dismount the impeller (55) hold the motor shaft with the aid of
a clamp, while rotating the nut (57) to the left (anticlockwise) with a
wrench, thus releasing the impeller (55). In this way the mechanical seal
(74) is released, too.
9. ASSEMPLY
ATTENTION
"All parts to be assembly must be clean and in perfect condition for use".
In order to assemble the pump:
Assemble the mechanical seal (80). Press this (74) until its locates into
l
the space; the seal will have been lubricated with water beforehand.
Assemble the impeller (55) on the shaft (1), affixing it with the key (57),
l
impeller washer (56) and impeller nut (57). In this way, the two halves of
the mechanical seal are joined.
Fix the motor to the pump casing (62) by means means of the screws
l
(63), impeller washer (56) and pump housing nut (107).
10. SPARE PARTS
To order any spare parts, indication must be given of the part, number
shown on the detail drawing (fig 3) and nameplate ratings (120).
WARNING:
ALL THE ADJUSTEMENTS THAT ARE MADE TO THE EQUIPMENT
MUST BE MADE BY THE AUTHORIZED TECNICAL SERVICE. IF NOT
THE GUARANTEE IS VOID AND WE ACCEPT RESPONSABILITY.
IF THE EQUIPEMENT IS USED FOR ANY OTHER MEANS THAN SPECI-
FIED BY THE MANUFACTURED, THE PROTECTION OF THE EQUIP-
MENT COULD FAIL, THEREFORE LOSING THE COVER OF GUARAN-
TEE.
