• Cleaning of the sheet steel panels must be carried out only with cloths dampened with water and soap.
• In case of tenacious stains, damp the cloth with a 50% mixture of water and denatured alcohol or with
specific products.
• Once cleaning is complete, dry the surfaces with care.
Do not use a chemically treated or antistatic cloth to clean the appliance.
Do not use gasoline, solvent, polish or similar solvents.
These products could cause the breakage or deformation of the plastic surface.
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
expansion 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 exter-
nal 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 Aquadue 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 Aquadue 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.
Undo the fixing nut (E) by releasing the terminal of the cable + of the tester anode with a 14mm wrench.
b.
Unscrew the magnesium anode (C) with a 26mm wrench.
c.
Insert the magnesium anode (C) 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.
d.
Check the seal of the reservoir during filling phase with water.
