WARNING
Warns that failure to observe the precau-
tions involves the risk of damaging the
pump and/or the plant.
1. GENERAL
The purpose of these instructions is to ensure the correct installation and
best performance of our pumps.
These are single cell centrifugal pumps with built-in filter elements,
especially designed for prefiltering and recirculation of water in swim-
ming pools.
They are designed to operate with clean water at a maximum tempera-
ture of 35
C.
o
All materials used are of top quality; they are subjected to strict controls
and verified to extremely demanding standards.
Correct compliance wit the installation and operation instructions, and
with the electrical connection diagrams, will prevent motor overloads
and the consequences of all types that could otherwise result, conse-
quences for which we decline all responsability.
If the pump is not fixed, do not operate if there are people in
the swimming pool.
2. INSTALLATION
The installation of our electric pumps is only permitted in
swimming pools or ponds that meet DIN standards VDE 0100
part 702/11.82. In case of doubt, inquire with an expert.
The pump should be installed as near as possible to water
level, in horizontal position, in order to obtain a minimum suc-
tion path and reduce head losses.
It is not advisable to install the pump at more than 3 m geo-
metrical height from water level.
Independently of the geometrical height and the power of the
model chosen, self-priming times may be up to 10 min.
The pump must be fixed on a firm base, with screws of 6 or
8 mm diameter, through the prepared holes in the foot.
The pump should be protected from possible flooding and
receive dry ventilation.
3. PIPEWORK ASSEMBLY
Suction and discharge pipework must have supports independent of the
pump.
The suction hose tail is built into the filter cover assembly, for this reason
the suction pipe must be flexible to enable easy removal of the cover.
The suction hose connection should be made using a good quality hose
clip, ensuring that an air tight seal is made (This is important to avoid the
pump sucking in air).
together with one of the following
The pump is supplied with one or two two-part-hose-tail union.
Optionally it can be supplied with one or two two-part union for solvent
gluing.
Suction pipe should be installed with a slight incline to avoid air locks.
4. ELECTRICAL CONNECTION
On fixed installations, know in advance how to isolate the
electrical charge to the pump.
The electrical installation should have a multiple separation
system with contact opening of at least 3 mm.
The protection of the system will be based on a differential
switch (l fn = 30 mA). If outdoor operation is foreseen, the
power supply cord should meet EEC standards (2) or be of
type H07 RN-F as per VDE 0250.
Single-phase motors will be equipped with built-in thermal
protection. In the case of three-phase motors, the user should
provide thermal protection complying with the installation
rules in force.
The diagrams in Fig. (1) will allow correct electrical connec-
tion.
5. VERIFICATIONS PRIOR TO INITIAL START-UP
After making the connections defined in the preceeding sec-
tion, unscrew the filter cover and fill the pump prefilter with
water to the bottom level of the suction line.
Verify that the pump shaft turns freely.
Verify that the mains voltage and frequency match those spe-
cified on the nameplate of the pump.
Set the prefilter cover back in place and screw it to a suitable
tightness.
Check that the turning direction of the motor matches that spe-
cified on the fan cover. In three-phase motors, if the turning
direction is incorrect, reverse two supply phases on the pro-
tection panel.
If the motor does not start, try to determine the cause of the
irregularity by consulting the list of common faults and their
possible solutions, provided in this manual.
NEVER RUN THE PUMP DRY.
6. STARTING
Open all the gate valves and put the motor under voltage. Wait a reasona-
ble time to allow self-priming.
Verify the breakaway current and suitable adjust the thermal relay.
7. MAINTENANCE
Our pumps do not require any specific maintenance. It is
advisable, however, to periodically clean the pump filter and
to empty the pump housing in low-temperature periods
through the blowoff plug. If the pump is to remain idle, it is
advisable to empty and clean it, and then reinstall the filter
cover with petroleum jelly on the rubber gasket, taking
measures to ensure that the place where the pump is to be
stored will remain dry and ventilated.
In the event of breakdown, the user must in no event handle
the pump, but must contact an authorised technical service.
When the time comes to dispose of the pump, it contains no
toxic or contaminating materials. The principal components
are duly identified for selective breaking.
