OUT
IN
When the pump is installed outside, we recommend to
foresee a simple protection against the weather (rain,
sun etc.).
Caution
Caution
Implement appropriate measures to attenuate the noise
generated by the pump to avoid damage to the environment.
Fastening the pump to the foundation should be effected
exclusively by means of bolts, threads or dowels, in order to
avoid blocking the removal of the motor unit! Make sure that
there is enough space between fan cover and wall, minimum
50 mm. You also need enough space to permit disassembly
of the strainer basket, minimum 210 mm towards above.
The pump should be installed at water
level or below water level and in
horizontal position, in order to keep
the suction path as short as possible
and to reduce head losses. The Aqua
Plus is self-priming and should never
be installed more than 2 m above
water level. Make sure that the suction
line is not leaky, otherwise the pump
will prime insufficiently or not at all.
The adhesive bonds at the suction
and pressure lines require more time
to cure, allow at least 12 hours before
starting the pump.
All electrical connections should be performed by a qualified expert only!
The use of pumps for swimming pools and the restricted area around them is only permitted if
pumps are installed in accordance with DIN/VDE 0100 part 702. The supply circuit has to be
protected with a fault current contactor with a nominal fault current of
I
DN
£ 30 mA.
Please make sure that the electrical installation has a disconnecting device, which allows
disconnecting from the power supply with a minimum of 3 mm contact gap at each pole. The
electrical wiring used (H05RN F for inside, H07RN F for outside) must have a minimum cross
section of 1 mm².
Pumps with A.C. motors are equipped with a built-in thermal cut-out in the windings.
