or material losses.
Before any work, ensure suffi cient clearances for the
installation.
Handle sharp-edged components carefully.
11.1 Water connection
!
Material losses
Carry out all water connection and installation work in
accordance with local plumbing regulations.
The following material combinations are approved for pipework
installations:
Cold water inlet
DHW outlet
Copper pipe
Copper pipe
Steel pipe
Steel pipe or copper pipe
PEX tubing
PEX tubing
Thoroughly fl ush the pipework before connecting the ap-
pliance. Foreign bodies, such as welding pearls, rust, sand
or sealant can impair the operational reliability of the
appliance.
!
Material losses
To protect the connection nipples against corrosion the
water tube connection must be made with plumber’s
thread seal tape (PTFE). The use of hemp on nipple
threads is not permissible due to risk of corrosion.
11.1.1
Safety valve
The appliance is a sealed unvented DHW tank. The appliance is
supplied with a temperature and pressure relief valve that has
been factory installed and leak-tested.
Install a type-tested safety valve in the cold water supply
line. The response pressure of the safety valve must be below
or equal to the permissible operating pressure of the DHW
tank.
The safety valve protects the appliance against unacceptable ex-
cess pressure.
Ensure that the expansion water escaping from the safety
valve can drip into a drain, e.g. a tank or sink.
Ensure the drain cannot be shut off.
Size the drain in a way that water can drain off unimpeded
when the safety valve is fully opened.
Ensure that the discharge pipe of the safety valve is open to
atmosphere.
Fit the discharge pipe of the safety valve with a constant
downward slope and in a room free from the risk of frost.
