– Open the system shut-off devices
– Start the filling by slowly opening the system water fill cock “A”
outside the appliance
– When water begins to come out of the vent valves, close them
and go on filling up to the system set pressure value.
Check the connections for tightness.
A
It is recommended to repeat this operation after some hours of operation and periodically check the
system pressure. Do the topping up after switching off the machine (pump “OFF”)
The system must be filled at a pressure between 1 and 2 bars, which can be checked through the gauge on the unit .
EMPTYING
– Before starting to empty the system, turn OFF the main system
circuit breaker)
– Check if the system water fill/top-up cock is closed
– Open the equipment front inspection panel.
– For 5-6-7-8 types and 13-14-15-16 types, open the by-pass valve (to be installed downstream of the machine), the equipment drain
cock, the system drain cocks and all vent valves.
– For 1-2-3-4 types and 9-10-11-12 types, open the two equipment drain cocks, the system drain cocks and all vent valves.
If antifreeze liquid has been added to the system, it should not be freely drained since it is polluting. It must be collected for possible
reuse.
