Safety

InStallatIOn

7.  safety

Only a qualified contractor should carry out installation, commis-

sioning, maintenance and repair of the appliance.

7.1  general safety instructions

We guarantee trouble-free function and operational reliability 

only if the original accessories and spare parts intended for the 

appliance are used.

7.2  instructions, standards and regulations

Note

Observe all applicable national and regional regulations 

and instructions.

8.  appliance description

8.1  standard delivery

Delivered with the appliance:

- Thermometer (delivered inside the control panel)

- Cold water inlet pipe with flat gasket

- Adhesive rose for DHW circulation line

- Adaptor with flat gasket for the connection of a DHW circula-

tion line

- Plastic cap

8.2  accessories

required accessories

Depending on the static pressure, safety assemblies and pressure 

reducing valves are available. These type-tested safety assemblies 

protect the appliance against unacceptable excess pressure.

Further accessories

If it is not possible to fit an anode rod from above, install a seg-

mented signal anode.

9.  Preparations

9.1  installation site

Always install the appliance in a room free from the risk of frost 

and near the draw-off point, and secure the appliance to the floor.

9.2  transport

!

Material damage

We recommend removing the cylinder casing during 

transport to the installation location, to prevent it from 

becoming dirty or damaged (see chapter "Installation / 

Fitting the cylinder casing and DHW circulation line if 

required").

10.  installation

10.1  Fitting the cylinder casing and dHw circulation 

line if required

Note

Fit the cylinder casing with cover before making the water 

connection and, if necessary, the DHW circulation line or 

the flanged immersion heater.

The plinth trim should be fitted after the tightness check.

A DHW circulation line can be fitted to the "DHW circulation" 

connection (see chapter "Specification / Dimensions and connec-

tions"). Alternatively, the "DHW circulation" connection can be 

used to connect a thermometer.

f

f

During fitting, counterhold the fitting with an open-ended 

spanner (size 36).

f

f

Check the rigidity of the connecting pipe and secure it further 

if required.

ff

Size the drain so that water can drain off unimpeded when 

the safety valve is fully opened.

ff

Fit the discharge pipe of the safety valve with a constant 

downward slope and in a room free from the risk of frost.

ff

The safety valve discharge aperture must remain open to the 

atmosphere.

10.5  Power supply

WARNING Electrocution

Before any work on the appliance, disconnect all poles 

from the power supply.

WARNING Electrocution

The connection to the power supply is only permissible 

as a permanent connection in conjunction with the re-

movable cable entry. Ensure that the appliance can be 

separated from the power supply by an isolator that dis-

connects all poles with at least 3 mm contact separation.

WARNING Electrocution

Ensure that the appliance is earthed.

Warranty

The warranty conditions of our German companies do not 

apply to appliances acquired outside of Germany. In countries 

where our subsidiaries sell our products, it is increasingly the 

case that warranties can only be issued by those subsidiaries. 

Such warranties are only granted if the subsidiary has issued 

its own terms of warranty. No other warranty will be granted.

We shall not provide any warranty for appliances acquired in 

countries where we have no subsidiary to sell our products. 

This will not affect warranties issued by any importers.
