Safety precautions
This symbol
"Danger" or "Warning" indicates the risk level deriving from failure to observe
the prescribed safety precautions:
DANGER
Warns that failure to observe the pre
risk of
cautions involves a risk of electric
electric shock shock.
DANGER
Warns that failure to observe the pre-
cautions involves a risk of damage to
persons and/or things.
WARNING
Warns that failure to observe the precau-
tions involves the risk of damaging the
pum 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, espe-
cially designed for prefiltering and recirculation of water in swimming
pools.
They are designed to operate with clean water at a maximum tempera-
ture of 35°C.
All materials used are of top quality; they are subjected to strict, controls
and verified to extremely demanding standards.
Correct compliance with 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,
consequences for which we decline all responsability.
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
suction path and reduce head losses.
It is not advisable to install the pump at more than 3 m
geometrical 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. INSTALLING THE LINES
The supports of the suction and discharge lines will be independent of
those of the pump.
In the case of plastic lines, ensure tightness of joints and threads with
TEFLON tape alone. Glue or similar products should not be used.
The suction line should have a diameter equal to or greater than that of
the suction mouth of the pump.
The inside of the suction and discharge holes is threaded to a certain
depth. This depth should not be exceeded when screwing on the respec-
tive lines. Only new or clean connectors should be used.
together with one of the following words
The suction lines should be structured with a slight slant to prevent the
formation of siphons.
4. ELECTRICAL CONNECTION
The electrical installation should have a multiple separation
system with contact opening of a least 3 mm.
The protection of the system will be based on a differential
switch (I 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 pro-
tection. 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
specified 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
specified on the fan cover. In threephase 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
reasonable 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.
