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 be-
yond 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.

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.
In case of intervention by this safety device as a result of overheating, disconnect from the power supply and leave the motor
to cool until it reaches an acceptable temperature. Before re-using the pump, check to verify the reasons which caused the
motor to overheat.
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 2 m for the cable. If the cable is longer, the cross-section must be increased in a
suitable manner pursuant to currently applicable regulations.
CONNECTION TO THE MAIN
The installer will have to make sure that the electric supply system has an adequate grounding compliant with
the laws in force.
Check that the supply system has a differential switch with a degree of sensitivity of _ = 30 mA (EN 61008-1 /
EN 61009-1).
Before removing the cover from the terminal block of the motor and before performing operations on the ma-
chine, make sure that the supply 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 pursuant to currently applicable regulations.
The following must be used as a conductor for the connection:
• Outdoors → cable H07RN-F
• In inside areas → cable H05RN-F or H07RN-F
• 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.
• The pump has built-in , automatic reset thermoamperometric protection. (single phase only)
• The electrical power line must be fitted with a short circuit protection device, and a residual current device (RCD) with
high sensivity (30mA), protected by means of a slow-acting fuse or a magnetothermic switch.
Do NOT open the connection box with Integrated 'LOGIC SAFE' safety device. Opening the box might cause electrical discon-
nect or short circuiting. Opening the box will cause a void of warranty.
Connect the pump to your electrical cabinet by use of the pre-installed power cable.
Installations and modifications should only be executed by a qualified electrician.
