INSTALLATION

Preparation

Permissible water line materials

- Cold water inlet line:

Pipes made from galvanised steel, stainless steel, copper or

plastic

- DHW outlet line:

Pipes made from stainless steel, copper or plastic

Material losses

If using plastic pipework, please note the maximum inlet

temperature and maximum permissible pressure (see

chapter "Installation / Specification / Data table").

Flow rate

f Ensure that the flow rate required to switch on the appliance

is achieved (see chapter "Installation / Specification / Data

table", On).

f Increase the water line pressure if the required flow rate is

not achieved when the draw-off valve is fully open. If the

flow rate is not reached despite increasing the pressure, re-

move the flow limiter and install the plastic profile washer.

Flow pressure

If the minimum flow rate required to switch on the appliance is not

achieved even when the tap is fully open, the flow limiter must be

removed. Replace it with the plastic profile washer supplied. You

can also increase the pressure in the water installation if required.

1 Flow limiter

2 Plastic profile washer

Note

For the thermostatic valve to function correctly, the flow

limiter must not be replaced with the plastic profile wash-

er.

Flexible water connection lines

f If the appliance is installed with flexible water connection

lines, ensure that the pipe bends do not become twisted.

Pipe bends have a bayonet fitting and are installed inside the

appliance.

f Secure the back panel with an additional screw at the

bottom.
