3.11 - FILLING THE SYSTEM
Warning!
Do not mix the CH system’s water with
unsuitable antifreeze products (example:
anti-freeze solutions for motor
vehicles) or use wrong concentrations of
anti-corrosion solutions ! This could cause
damage to the washers and could provoke
noise during normal boiler operation.
If really necessary, use exclusively specific
anti-freeze products suitable for use on
aluminium-silicon alloy.
UNICAL refuses all liability for injury to persons, animals
or damage to property deriving from not having respected
the above mentioned recommendations.
After completing all the system’s service connections the
circuits may be filled by carefully following out the following
phases:
- open the radiator’s air vents and check that the automatic
air vent in the boiler is working properly.
- gradually open the appropriate filling cock and check that
the automatic air vents fitted onto the system are working
properly.
- close the radiator’s air vents as soon as water begins to
flow out.
NOTE!
If the appliance has not been fired for a long
period the pump could be jammed. Before firing
the boiler, it is important to carry out the
following un-jamming operation:
-
place a cloth underneath the pump
-
remove the pump vent plug positioned in
the centre of the pump
-
using a screwdriver, rotate the shaft in a
clockwise direction.
Once this operation has been concluded,
screw back the pump vent plug and check that
there have been no water leaks.
