11.1 GENERAL MAINTENANCE
The coolant in the device can be handled
ONLY
by a qualified refrigeration technician with valid
authorisation.
Over the lifetime of the appliance, user must perform general maintenance and control of the appliance
depending on the place of installation:
• Surface cleaning of the appliance and the surrounding area with a wet cloth
• Visual inspection of the entire appliance in order to detect possible leakage and mechanical
damage to the appliance.
11.2 DRAINING WATER FROM THE TANK
Remember that the water in the hot water tank may have a high temperature , and therefore
a risk of scalding may be present.
Before emptying the hot water tank, allow temperature of hot water to drop to a level at which
scalding can no longer occur.
Once the water temperature is at a safe level at which scalding can no longer occur, proceed as follows:
• Disconnect the system from power.
• Close the inlet cold water valve and open the hot water tap.
• Open the drain valve of the system.
11.3 MAGNESIUM ANODE
The appliance is equipped with a magnesium anode that, together with the materials used in the receptacle,
ensures effective
protection against corrosion.
The inner enamel surface of the tank ensures effective protection against corrosion which helps to maintain
water quality
within the health parameters. However, the characteristics of water vary according
to the installation location (see Section 4.4 and warranty).
A the user's installation location the quality of water can be aggressive for the appliance. Therefore
a magnesium anode is supplied together with the device that wears over time and protects your appliance.
Wear of the anode depends on the characteristics of the water used. Checking the status of the anode
is so very important, especially in the early years of the installation:
To check the status of the anode, follow these steps:
• Disconnect the appliance from the electrical outlet.
• Shut off the water supply.
• Reduce the pressure (for example, open a hot water tap) and reduce the water level.
• Unscrew the anode using a suitable tool.
• Check the wear of the anode and replace it if necessary.
• If the diameter of the anode is less than 15 mm, it needs to be replaced.
