Maintenance - Atlantic CORTHERM 500 Installation, Betrieb Und Wartung

• Verifi cation 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
EN
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 for a few seconds 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 fl uids 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 fl ange and drainage fl ange: 8 Nm.
• Water heater 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's safety
valve checked at least every year. The valve should begin to open at its set pressure and
allow full fl ow at an additional 0.5 bar.
• Anode: The anodes should be inspected every year and replaced when three quarters of
the magnesium has been consumed. If there is not enough headroom beneath the ceiling,
anodes are available in a chain version (refer to the specifi c anode manual).
For insulated versions, inspect for wear without removing the anode. The values are given
as a guide, and were produced for water with a conductivity of 500 μs/cm.
Disconnect the anode from the tank, pulling out the lug on the anode. Measure the amperage
between the lug and the anode using a multimeter. If the amperage is less than 0.5 mA of
direct current on the fi rst reading, replace the anode. If the anode does not need to be
replaced, do not forget to reconnect it.
• If the tank is to remain without operating over the winter in premises where there is a risk
of freezing, the water heater must remain powered up with the thermostat set to its
lowest setting.
• Check the tightness of the electrical connections.
For all operations on components containing artifi cial siliceous mineral fi bres (ceramic
fi bres, glass wool, rock wool), the operator must wear suitable protective clothing and
a breathing mask to avoid any risk specifi c to these products.
