7. COMMISSIONING

• Fill the device
- Open a hot water tank in the distribution system,
- Open the cold water tap on the safety unit, ensuring that the unit's drainage valve is
closed,
- After drawing from the hot water taps with no noise in the pipes, close the taps: your
equipment is full.
• Verification of correct operation
- During heating, the water drips out of the safety unit drain hole (this hole should be
connected to the drain). This phenomenon is normal. The water expands as it is heated,
and the additional volume can reach 2 to 3% of the device's capacity.
- Check the watertightness of the pipe connection.
- Check that the hydraulic components are operating correctly by putting the safety unit in
the drainage position and the stop position and vice versa to eliminate any build-up.

8. MAINTENANCE

The device you have just purchased should provide satisfactory service for many years as
long as this advice is followed:
• IMPORTANT: put the safety unit in the drainage position at least once a month to
evacuate any deposits that can obstruct the safety unit's safety valve over time.
Failure to respect this maintenance rule can lead to the deterioration of the tank (not
covered by the warranty).
• Cleaning: once a year. The cleaning frequency should be adjusted according to the
quality of the fluids stored (water hardness) and the volume of water consumed. A
lateral inspection cover or manhole is provided for cleaning. Replace the seals each time it
is disassembled.
Cover plate tightness:
Lateral flange and drainage flange: 8 Nm.
• Tank cleaning: the drainage tube placed at the lowest point of the tank enables it to be
drained fully.
• Specialist maintenance: have the watertightness and operation of the safety unit safety
valve checked at least every year. The valve should begin to open at its set pressure and
allow full flow at an additional 0.5 bar.
