Safety precautions
This symbol together with one of the
following words “Danger” or “Warning” indicates the
risk level deriving from failure to observe the
prescribed safety precautions:
DANGER
risk of
electric
shock
Warns that failure to observe
the pre cautions involves a
risk of electric 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 pre cautions involves the
risk of damaging the pump
and/or the facility
1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump.
Save them for future reference.
These are single-stage, centrifugal electric pumps,
especially designed for water recirculation in hot
tubs and spas.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 50ºC.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
2. HANDLING
The pumps are supplied suitably packaged to prevent
damage in transit. Before unpacking, check that the
packaging has not been damaged or deformed,
Lift and handle the product with care and with
the right tools.
3. INSTALLATION
These pumps are designed for indoor use.
The pump should be protected from possible
flooding and receive dry ventilation.
To connect dispensers and pressure gauges, make
4mm diameter holes in the suction inlet and
discharge outlet and fit pipes of approximately 9mm
interior diameter.
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.
3.2. Suction pipe assembly
The suction pipe must be of the same or greater
diameter than the pump inlet and installed in an
upward inclination to prevent trapped air pockets
forming.
The suction pipe of the pump should be as short as
possible.
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 3mm contact
openings, The protection of the system will
be
based on a differential switch
(Δfn = 30mA)
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 protection.
All of three phase motor pumps do not
incorporate this protection. They must be
connected to a motor-protective circuit
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.
