3.1 COOLING THE MOTOR

Follow the precautions described below to ensure that the motor and electronics are cooled:
• Install the pump in a well-aerated
area to guaranteed sufficient cooling
to the motor and electronics

3.2 HYDRAULIC CONNECTION

The system can be used with a direct connection to the aqueduct or suction from a first tank (see chapter 8.2 – 8.3).
ATTENTION
For connection to the aqueduct, pay full attention to local standards in force.
ATTENTION
Check the sum of the intake pressure and the maximum pressure of the motor pump do not exceed the maximum
values allowed by the system.
TANK
follow the indications described in the use and maintenance manual for the motor pump used. It is possible to use a float to
deactivate the system (to avoid the system drying up).

3.3 PRESSURISED TANK (EXPANSION VESSEL)

ATTENTION
Check the maximum pressure of the tank can support the maximum pressure of the system.
It is necessary to install an expansion vessel on the outlet side of at least 8 litres to avoid the motor pump functioning continuously.
Check the preloading pressure of the first tank on the system: this value must be 0.5/0.8 Bar less than working pressure
(lower SET-POINT).

3.3 MOTOR PUMP ELECTRICAL CONNECTION

WARNING
Ensure power is cut to all the connections.
WARNING
Always disconnect the electrical power cable before performing operations on the electrical or mechanical parts of the
motor pump.
WARNING
Having disconnected the power cable, wait for the LINE led to switch off (about 2 minutes) and until the condensers
unload before performing intervention on the CPS.
ATTENTION
Perform the electrical connections in compliance with local standards in force.
ATTENTION
It is the responsibility of the installer to ensure that the electrical power supply system has an effective earthing system
in compliance with standards in force.
