Water circuit connection
The module must be connected to a
suitably-sized heating/cooling system
in accordance with its performance lev-
els.
Prior to connecting the module, per-
form the following:
- the system tubes are thoroughly
washed in order to remove any
swarves, welding residues or dirt
which might prevent the system from
operating correctly
- the primary circuit pressure does not
exceed 3 bar
- the delivery temperature is no great-
er than 85°C;
- all safety and operating devices nec-
essary for correct operation of the
system are in place
- the expansion vessel capacity is
suited to the amount of water in the
system.
The module is equipped with a shut-
off valve which facilitates checking and
makes it easier to perform any neces-
sary maintenance procedures.
