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 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

The following are delivered with the appliance:

- Safety valve 

The safety valve supplied must not be used in Belgium. 

For use here please use standard safety valves (see also 

pricelist).

8.2  accessories

Pressure-tested taps are available as accessories.

9.  Preparations

9.1  installation site

The appliance is designed to be permanently wall-mounted to a 

solid surface. Ensure the wall offers adequate load bearing ca-

pacity.

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

the expansion water.

Always install the appliance vertically in a room free from the risk 

of frost and near the draw-off point.

It may not be fitted in a corner since the screws for fixing the 

appliance to the wall must remain accessible.

9.2  Fitting the wall mounting bracket

Note

Ensure that the temperature selector is accessible from 

the front.

The mounting bracket attached to the appliance has hook-in slots, 

which in most cases enables 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 and secure the wall mounting bracket 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 horizontally.

10.1  water connection

!

Material losses

Carry out all water connection and installation work in 

accordance with regulations.

Operate the appliance only with pressure-tested taps.

10.1.1  Permissible materials

!

Material losses

When using plastic pipework, observe the manufacturer's 

data and the chapter "Specification / Fault conditions".

cold water line

Galvanised steel, stainless steel, copper and plastic are approved 

materials.

dHw line

Stainless steel, copper and plastic pipework are approved ma-

terials.

10.1.2  Fitting the safety valve

Note

The safety valve supplied must not be used in Belgium. 

For use here please use standard safety valves (see also 

pricelist).

Note

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

pressure reducing valve in the "cold water inlet".

The maximum permissible pressure must not be exceeded (see 

chapter "Specification / Data table").

f

f

Install a type-tested safety valve in the cold water supply 

line. Please note that, depending on the static pressure, you 

may also need a pressure reducing valve.

f

f

Size the drain so that water can drain off unimpeded when 

the safety valve is fully opened.

f

f

Fit the discharge pipe of the safety valve with a constant 

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

f

f

The safety valve discharge aperture must remain open to the 

atmosphere.

10.2  Power supply

WARNING Electrocution

Carry out all electrical connection and installation work 

in accordance with relevant regulations.

Before any work on the appliance, disconnect all poles 

from the power supply.

WARNING 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.

WARNING Electrocution

Ensure that the appliance is earthed.

!

Material losses

Observe the type plate. The specified voltage must match 

the mains voltage.

Power cable

DANGER Electrocution

The power cable must only be replaced (for example 

if damaged) with the original spare part by a qualified 

contractor authorised by the manufacturer.

The appliance is supplied with a flexible power cable with wire 

ferrules and without plug, ready to connect.

f

f

If the power cable is of insufficient length, unclamp it from 

the appliance. 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.

commissioning

11.  commissioning

11.1  commissioning

Note

Fill the appliance with water prior to electrical connec-

tion. If you switch on the appliance while empty, the high 

limit safety cut-out will switch it off.

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

Open the shut-off valve in the cold water feed line.

f

f

Open a draw-off point until the appliance has filled up and 

the pipework is free of air.

f

f

Adjust the flow rate. For this, observe the maximum permis-

sible flow rate with a fully opened tap (see chapter "Specifi-

cation / Data table").

f

f

If necessary reduce the flow rate at the butterfly valve of the 

safety valve.

f

f

Turn the temperature selector to maximum.

f

f

Switch the mains power ON.

f

f

Check the function of the appliance. Ensure that the thermo-

stat switches off.

f

f

Check that the safety valve is working correctly.

11.1.1  appliance handover

f

f

Test the safety valve regularly.

14.2  draining the appliance

WARNING Burns

Hot water may escape during the draining process.

If is necessary to drain the cylinder for maintenance or to protect 

the whole installation from frost, proceed as follows:

f

f

Close the shut-off valve in the cold water feed line.

f

f

Open the DHW valves of all draw-off points until the appli-

ance is fully drained.

f

f

Drain any residual water from the safety valve.

14.3  checking / replacing the protective anode

f

f

Check the protective anode after the first year of use and re-

place if necessary.

f

f

Next, decide the time intervals at which further checks 

should be carried out.

14.4  descaling

f

f

Remove loose scale deposits from the water heater.

f

f

If necessary, descale the inner cylinder with commercially 

available descaling agents.

f

f

Only descale the flange after disassembly and never treat the 

cylinder surface and protective anode with descaling agents.

14.5  anti-corrosion protection

Ensure that while carrying out maintenance work the anti-corro-

sion protection (560 Ω) is not damaged or removed. Reinsert the 

anti-corrosion protection correctly after replacement.

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.
