5.4 Plumbing Connections

Care must be taken to ensure that no leaks
occur following installation of connections
If the inlet and outlet pipes are connected
directly to the pump, only use Teflon sealing
tape to ensure a good seal.
If screw fittings are used, these must not be
sealed by sealing compounds. Screw fittings
seal with the aid of an O-ring and need only be
tightened hand-tight.
The pump inlet and outlet thread connections
are equipped with a thread stop. The
connecting fitting cannot be forced beyond this
point.
Do NOT over-tighten connection points.
Hand-tight plus no more than 2 turns
should be sufficient.
The piping installation should be started at the
pump in order to avoid stresses to the pump
housing – when possible. Air pockets can be
avoided by installing the suction line at a slight
incline toward the pump. A straight pipe of at
least 50cm in length should be installed to the
suction connection.

5.5 Electrical Connections

This must be done by a certified Electrician. A
separator must be installed in the electrical
system which allows disconnection from the
power supply with a contact opening gap for
each pole of at least 3 mm. The manufacturer
accepts no liability for damage to the motor
that can be prevented by the installation of an
external protection switch. Please use the
electrical data from the motor nameplate for
any electrical system sizing. Otherwise, all
guarantee claims are invalid in the event of
damage to the motor and/or pump.
The product must be grounded.

5.6 Connection to the mains

The installer will have to make sure
that the electric supply system has
an adequate grounding compliant
Danger
with the laws in force.
Check that the supply system has a
differential switch with a degree of
sensitivity of _ = 30 mA (EN 61008-
Danger 1 / EN 61009-1).
Before removing the cover from the
terminal block of the motor and
before performing operations on the
machine, make sure that the supply
Danger
line has been cut-off.
To connect the machine to the mains, perform
the operations described here below:
Make sure that the motor is suitable to the
mains voltage and frequency.
Cut the electric system off by using a cut-off
switch.
Check to ensure that certified cables are
used in accordance with current regulations,
with three cross-sections (2 + earth) of at
least 0.75 mm², with a maximum length of 5
m for the cable. If the cable is longer, the
cross-section must be increased in a
suitable manner
applicable regulations.
The following must be used as a conductor for
the connection:
- Outdoors
- In inside areas
For ambient temperatures of 40°to 50°C,
supply cables with temperature characteristics
of at least 95°C and minimum wire gauge of
1.5mm2 must be used.
