3.1.1 Hydraulic safety unit
(mandatory)
You must install a hydraulic safety unit (Supplied in G3 Kit) complying with EN 1487 or with
equivalent local standards in force;
•
Check valve;
•
Check valve control device;
•
Safety valve;
•
Hydraulic load interrupting device.
The above components are required to safely run the supplied equipment. The rated calibration
pressure of the hydraulic safety unit must be of 0.6 MPa (6 bar). Pay attention while installing the
hydraulic safety unit, avoiding forcing or altering it. Water may drip from the hydraulic safety unit
discharge connector (see paragraphs
“USAGE INSTRUCTIONS (user) - Water dripping from the
hydraulic safety unit
”). This opening must be left exposed to the atmosphere. You need to install a
discharge pipe, with a constant downward slope, in a condensate- and ice-free area. There must be
no obstructions in the pipe, to avoid overpressures.
3.1.2 Pressure reducer
Should the network pressure exceed 0.6 MPa (6 bar), you need to install an appropriate pressure
reducer upstream of the hydraulic safety unit, ensuring the indicated operating range.
3.1.3 Expansion tank
To prevent any overpressures that might damage the equipment, frequently triggering the safety
unit and causing water dripping,
U
it is mandatory
U
that you install an adequate expansion vessel.
Install it in accordance with the instructions provided by the manufacturer. The expansion tank is
required to keep pressure constant and avoid harmful pressure shocks or accidental overpressures.
3.2 Unit filling
WARNING:
U
Switching on the equipment when it is not filled with water will seriously damage
U
U
the refrigerating units and the electrical heating element.
WARNING:
U
In the presence of water with a hardness degree >20°TH (where 1°TH=French
U
U
degree=10mg CaCo3/l) it is mandatory that you install a softener to reduce limestone
U
U
scaling inside the boiler and keep the electrical resistance and the hydraulic safety unit in
U
U
good working order.
To fill the equipment, you need to:
•
open the main water supply or the equipment water supply valve;
•
open a hot water tap (e.g. bathroom, wash basin, etc.) to allow the water to flow out; when the
water outflow from the tap is constant the equipment will be full;
