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 operation 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:

- 2 fitted wall mounting brackets

- Safety valve (SYR) with non-return valve

9.  Preparations

9.1  installation site

The appliance is designed for installation on a solid wall. Ensure 

the wall offers adequate load bearing capacity.

There should be a suitable drain near the appliance to drain off 

the expansion water.

f

Install the appliance vertically or horizontally as shown in a 

room free from the risk of frost and near the draw-off point.

10.  Preparing for installation

10.1  Preparing to install the appliance

The wall mounting brackets attached to the appliance have hook-

in slots, which in most cases enable installation on the bolts that 

are already in place from previous appliances.

f

f

Otherwise, transfer the dimensions for the holes to be drilled 

on the wall (see chapter "Specification / Dimensions and 

connections").

f

f

Drill the holes, if required, and secure the wall mounting 

brackets with screws and rawl plugs. Select fixing materials 

in accordance with the wall construction/condition.

f

f

Hook the appliance with wall mounting brackets on to the 

screws or bolts. Observe the weight of the appliance when 

empty (see chapter "Specification / Data table") and, if neces-

sary, ask another person to help.

f

f

Align the appliance vertically or horizontally.

10.2  water connection

!

Damage to the appliance and environment

Make all water connection and installation work in ac-

cordance with regulations.

cold water line

Steel or copper pipes or plastic pipework are approved materials.

dHw line

Copper or plastic pipework are approved materials.

!

Damage to the appliance and environment

When using plastic pipework, observe chapter "Specifica-

tion / Fault conditions".

Note

If the water pressure is higher than 0.6 MPa, install a 

pressure reducer in the "cold water inlet".

Operate the appliance only with pressure-tested taps.

f

f

Thoroughly flush out the cold water line before connecting 

the appliance, so that no foreign matter gets into the water 

heater or safety valve.

f

f

Route the safety valve drain line to a drain free from the risk 

of frost, with a continuous downward slope to ensure the un-

restricted flow of the water to the drain. The discharge aper-

ture of the safety valve must remain open to the atmosphere.

PreParing for inStallation

10.3  electrical connection

DANGER Electrocution

Before any work on the appliance, disconnect all poles 

of the appliance from the power supply.

DANGER Electrocution

Carry out all electrical connection and installation work 

in accordance with relevant regulations.

DANGER Electrocution

Only use a permanent connection to the power supply. 

The appliance must be able to be separated from the 

power supply by an isolator that disconnects all poles 

with at least 3 mm contact separation.

Note

Observe the type plate. The specified voltage must match 

the mains voltage.

Note

Please note that the appliance must be connected to the 

earth conductor.

Power cable

DANGER Electrocution

The power cable must only be replaced (for example if 

damaged) by contractors authorised by the manufac-

turer.

The appliance is supplied with a flexible power cable with wire 

ferrules and without plug, ready to connect.

f

f

If the cable is of insufficient length, unclamp it from the ap-

pliance. Use a suitable installation cable.

f

f

When routing the new power cable, ensure that it is water-

proof as it passes through the existing cable grommet, and is 

correctly routed and connected inside the appliance.

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.

Environment and recycling

We would ask you to help protect the environment. After use, 

dispose of the various materials in accordance with national 

regulations.
