• The magnesium anode (optional) - Package EA 103
1.
Prepare a new sealing gasket.
2.
Cut the power supply to the boiler.
3.
Cut off the cold water supply and drain the DHW tank. To drain
though the safety unit, turn the unit to drain and turn on a hot
water tap (or a bleed valve) to allow air to enter.
4.
Remove the front panel and the sensors.
5.
Remove the inspection trap (13 mm spanner).
6.
Check the anode and replace it if necessary.
7.
Remove limescale deposits in the form of sludge or strips in the
bottom of the tank. On the other hand, do not touch limescale
adhering to the walls of the tank as it provides effective protection
against corrosion and improves the insulation of the DHW tank.
8.
Descale the exchanger in order to maintain its performance
levels.
9.
Fit the unit together. Replace the lip seal and position it in the visit
opening, making sure that you place its lug outside the DHW
tank. Be sure to replace the thimble tube on the hatch pointing
downwards.
10.
When replacing the titanium anode by a magnesium anode,
connect the TAS anode simulation connector
(provided with
package
) to the boiler's control panel, on the terminal
normally used by the titanium anode.
11.
After fitting, check the tightness of the seal on the calorifier.
The screws retaining the visit trap must be tightened
to 6 Nm +1/-0. Use a dynamometric spanner.
Comments: Approximately 6 Nm is obtained by
holding the box spanner by the small lever.
12.
Switch on.
