3.1. Fixing

The pump should be installed on a solid, horizontal
base, secured by screws or bolts and using the
existing holes in the mount.
The pump should be protected from possible
flooding and receive dry ventilation.

3.2. Suction pipe assembly

The pumps must be installed at least two meters
from the wall of the pool, and at the same height as
the level of the water, or if possible, below. The end
of the suction pipe must always remain at least
30cm below the water level.
The suction pipe, if longer than 7 meters, must be
of the same or greater diameter than the pump inlet
and installed in an upward inclination to prevent
trapped air pockets forming.
If the pump is required to perform a suction lift, to
avoid unnecessary losses of head on the discharge
side, the pump should be installed as close as
possible to the water. It is not advisable to install
the pump at more than 3m geometrical height from
the water level.

3.3. Discharge pipe assembly

It is recommended to use pipes with a diameter
equal or greater than the pump outlet. This will
reduce loss of head caused by friction in longer
pipe runs.
Pipework must be supported and their weight must
not rest on the pump.

3.4. Electrical connection

The electrical installation must have a multi-
pole isolator with minimum 3 mm contact
openings, The protection of the system will
be
based
on
(Δfn = 30 mA)
The power cable must correspond at least to the
type H07 RN-F (according to 60245 IEC 66) and
having terminals.
The connection and its dimensioning must be per-
formed by a qualified installer according to the
needs of the facility and following the regulations in
force in each country.
The power supply socket for the apparatus must be
at least 3.5m from the pool.
Single-phase motors have thermal protec-
tion.
All of three phase motor pumps do not
incorporate this protection. They must be
connected
to
a
breaker that can be adjusted manually. Set
the circuit breaker according to the current
given in the rating plate plus 10%.
Follow instructions given on fig.1 for correct
electrical connection.

3.5. Pre-start checks

Ensure the voltage and frequency of the
supply corresponds to the values indicated
on the electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body with water through the filter
cover to the bottom level of the suction line.
Check all joints and connections for leaks.
Set the prefilter cover back in place and screw it to
a suitable tightness.
THIS PUMP MUST NEVER BE DRY RUN.

4. STARTING

Ensure all valves in the pipework are open.
Connect power supply. There will be a delay before
water appears at the end of the discharge pipe.
Viewings from the fan ensure that the rotation of the
motor is clockwise. On three phase pumps the
motor may rotate anticlockwise. If this is happening,
the flow will be lower than expected. To rectify this
situation the two supply phases need to be re-
versed.
Ensure that the absorbed current is the same or
lower than the maximum shown on the name plate.
Adjust the thermal relay if is necessary.
If the pump fails to operate refer to the possible
faults, causes and solutions list for assistance.

5. MAINTENANCE

Under normal conditions these pumps require no
special or planned maintenance.
Clean the pump with a damp cloth without using
harsh products.
If the pump is not to be operated for a long
period it is recommended to remove it from
the installation, drain down and store in a dry,
well ventilated place.
ATTENTION: In the event of faults or
damage occurring to the pump, repairs
should only be carried out by an authorised
service agent.

When the pump is eventually disposed of, please
note that it contains no toxic or polluting material.
All main components are material identified to allow
selective disposal.
