CAPITOLO 3 - INSTALLATION

Carefully read the use and maintenance manual for the pump.
3.1

COOLING THE MOTOR

Follow the precautions described below to ensure that the motor and electronics are cooled:
x
Install the pump in a well-aerated area to guaranteed sufficient cooling to the motor and electronics;
x
Ambient temperatures should not be above 40°C;
x
Keep the cooling fins and ventilator clean.
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).
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)

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

32
x
The installation operations must be performed by expert, qualified personnel.
x
Use specific guards and equipment as per safety standards.
x
Fully comply with safety and accident prevention standards in force.
x
For connection to the aqueduct, pay full attention to local standards in force.
x
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.
x
Check the maximum pressure of the tank can support the maximum pressure of
the system.
x
Ensure power is cut to all the connections.
x
Always disconnect the electrical power cable before performing operations on
the electrical or mechanical parts of the motor pump.
x
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.
x
Perform the electrical connections in compliance with local standards in force.
x
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.
