4.3.2. Safety valves

The safety valves are installed on the tank inlet using a tee (see diagrams below).
Only on cold water inlet
1 G 1" unit only
Never assemble a valve or no-return valve between the valve or the safety unit and the
!
tank.
On the cold water inlet of tanks equipped with valves, it is necessary to provide a no-return
valve preceded by a valve. To prevent scaling of its parts, operate the safety unit at least
once a month by placing its levers in different positions.

• Fill the tank
- Open a hot water tap on the distribution,
- Open the cold water tap located on the safety unit, making sure that the unit's drain valve
is in the closed position,
- After the flow to the hot water taps and without any noise in the piping, stop them: your
tank is full.
• The thermal wells are to be assembled using thermal paste. Follow these procedures for
every assembly.
The trilobal thermal wells and thermometer need to be tightened manually and do not need
to be watertight.
• Checking correct operation
- During heating, the water flows drop by drop through the drain hole in the safety unit (this
hole must be connected to the sewers). This is normal. The water dilates during heating
and the volume can reach 2 to 3% of the tank's capacity.
- Check that the pipe connectors are watertight.
- Check the correct operation of the hydraulic parts by placing the safety unit in the draining
position at the stop position and vice versa, so as to eliminate any waste.
