ATER CONNECTIONS
Connect the machine to the water pipes following the instructions located near its water
fittings (see figures).
Important!
Install the mechanical water filter, provided with the machine, on its
input: scum and impurities can seriously damage the evaporator. Not doing so will
void the warranty in case of breakages.
We recommend an extraordinary cleaning of the mechanical water
filter after the machine has been running for the first week
(also see Chapter
9 Maintenance and periodic inspections
).
3.4.1
Recommended water system
The standard equipment of a water circuit should include tank, pumps, expansion vessel,
safety valve, filter, shut-off taps.
In particular, we recommend that the water circuit also be equipped with:
•
A mechanical filter and a check valve upstream from the charging tap;
•
An air vent at the highest point of the plant;
•
A drain tap in the lowest point of the plant;
•
Manometers and thermometers at the machine’s water input and output to check its
functioning;
•
Vibration damping joints on the pipes to avoid the transmission of vibration to the
plant;
•
In the case of water circuits with considerable capacity, we recommend checking
whether it is necessary to supplement the expansion vessel already on the unit with
another additional one.
