To protect against corrosion and ensure compliance with the rules for
electrical safety, observe the following points:
Use metal fittings for drinking water heating systems with plastic
piping.
Use only original accessories from the manufacturer.
When installation of the tank is complete, inspect the ground
conductor (including metal fittings).
Maintenance
Customers are advised to:
Sign a maintenance and inspection contract with an authorized
contractor. Inspect and maintain the DHW tank as necessary on a
yearly basis. Service as needed.
Use only original spare parts.
Flooding
After a flood, do not use the appliance if any part has been
submerged. Damage to appliances that have been submerged can be
quite severe and pose numerous safety risks.
An appliance that was subject to flooding must be replaced.
1.3 Instructions for the owner and operator
Explain the operation and handling of the heating system and DHW
tank, making a particular point of safety-relevant features.
Explain the function and how to check the T&P safety valve.
Hand all enclosed documents over to the owner/operator.
Recommendation for the user: Sign a maintenance and inspection
contract with a licensed contractor.
Highlight the following for the user:
Water may be discharged from the T&P safety valve during heat-
up.
The blow-off line on the T&P safety valve must always be kept
open.
Check that the T&P safety valve operates properly at least once
yearly.
The tank must be inspected annually and maintained as required.
