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.

Instructions for the owner and operator
WARNING: Risk of scalding at the taps!
There is a risk of scalding at the taps if the tank
temperature is set above 122 °F (50 °C) and during
thermal disinfection.
▶ Advise users that they should draw off only mixed
water. Otherwise, install a thermostatic DHW mixing
valve.
NOTICE: Risk of tank damage from excessively high
pressure.
▶ Never close the temperature and pressure safety
valve blow-off line.
▶ 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.
