Periodic Maintenance; Check Of The Domestic Hot Water Reservoir Magnesium Anode - Olimpia splendid SHEPRA TOWER S2 Instructions Pour L'installation, L'emploi Et L'entretien

8.2 - PERIODIC MAINTENANCE

Periodic maintenance is essential in order to maintain the heat pump always efficient, safe and reliable over
time. Maintenance can be carried out periodically by the Technical Assistance Service, which is technically
authorized and prepared and also has, if necessary, original spare parts available.
The maintenance plan that OLIMPIA SPLENDID's Technical Assistance Service
or the maintenance technician must respect, with annual periodicity, includes
the following operations and checks:
• Expansion vessels pressure check (check pressure on the label of the ex-
pansion vessel).
• Water circuit filling.
• Presence of air in the water circuit.
• Efficiency of safety devices.
• Electrical power voltage.
• Electrical absorption.
• Electrical connections tightening.
• Cleaning of fans grilles and external unit battery fins.
• Check for presence of dirt on the metallic net filters.
• Check of the sacrificial anode.

8.2.1 - Check of the domestic hot water reservoir magnesium anode

The magnesium anode is a sacrificial anode which depletes during the use of the domestic hot water reservoir.
The magnesium anode must be subject to visual check at least every two years
(ref. standard DIN 4753).
The DHW reservoir of Sherpa Tower is equipped with a tester (fig.4 - rif.16) for check of the state of wear of
the anode.
For wear check (fig.3-4):
- Remove the front panel (P) of Sherpa Tower
- Press the button located on the tester anode (D)
Check the position of the needle, if the needle of the tester positions in the green zone, it is not
necessary to replace the magnesium anode.
If it positions in the red zone, it is necessary to replace the anode.
Proceed with the replacement of the anode as described below (Fig.4):
a. Remove the access cap to the anode (C) located on the thermoformed part of the domestic hot water
reservoir.
b. Undo the fixing nut (E) by releasing the terminal of the cable + of the tester anode with a 14mm wrench.
c. Unscrew the magnesium anode (F) with a 26mm wrench.
d. Insert the magnesium anode (F) in its seat by closing it hermetically during assembly with a suitable
sealant (for example: hemp or PTFE tape) avoiding that the bar enters in contact with oil or grease.
Keep maximum cleaning during the operations inside the domestic hot water reservoir.
e. Check the seal of the reservoir during filling phase with water.
f. Correctly reposition the anode access cap (C).
