Commissioning; Maintenance - Groupe Atlantic CORTEK Installation, Use And Maintenance Instructions

5. 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.

6. 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 is provided for cleaning. Replace the seals each time it is
disassembled.
Cover plate tightness: 9 Nm.
• 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 0,05 MPa (0,5 bar).
• Anode: The anodes should be inspected every year and replaced when 2/3 of the magnesium
has been consumed.
• If the tank is to remain without operating over the winter in premises where there is a risk
of freezing, the water must be kept above freezing point.
For all operations on components containing artificial siliceous mineral fibres (ceramic
fibres, glass wool, rock wool), the operator must wear suitable protective clothing and
a breathing mask to avoid any risk specific to these products.
