2. Safety

2.1 Intended 

use

This pressure appliance is designed to heat DHW. The appliance 

can supply one or more draw-off points.

Any other use beyond that described shall be deemed inappropri-

ate. Observation of these instructions and of instructions for any 

accessories used is also part of the correct use of this appliance.

2.2 

General safety instructions

CAUTION Burns

During operation, the tap can reach temperatures of 

around 55 °C.

There is a risk of scalding at outlet temperatures in ex-

cess of 43 °C.

!

WARNING Injury

Where children or persons with limited physical, sensory 

or mental abilities are allowed to use this appliance, 

ensure that this only occurs under supervision or after 

appropriate instruction by a person responsible for their 

safety.

Children should be supervised to ensure that they never 

play with the appliance.

!

Material damage

Protect the appliance and its tap against frost.

2.3 CE 

designation

The CE designation shows that the appliance meets all essential 

requirements according to the:

- Low Voltage Directive

- Electromagnetic Compatibility Directive 

The maximum permissible mains impedance is indicated in 

chapter “Specification / Data table”.

2.4 Test 

symbols

See type plate on the appliance.

Country-specific approvals and certifications: Germany

A general test certificate [Germany] as verification of suitability 

regarding noise emissions has been issued for this appliance, 

based on the State Building Regulations [Germany].

DIN 4109

PA-IX 6816/I

3. Appliance  description

The appliance heats potable water that flows through it. When 

a DHW valve is opened, the heater starts automatically as soon 

as the start-up volume has been reached. The heating output 

is determined and matched by the flow rate and the cold water 

temperature.

Heating system

The heating system is suitable for hard and soft water areas; it 

is not susceptible to scale build-up. The heating system ensures 

quick and efficient DHW availability.

Note

The appliance is equipped with an air detector that large-

ly prevents damage to the heating system. If, during op-

eration, air is drawn into the appliance, the heater shuts 

down automatically for one minute, thereby protecting 

the heating system.

Thermostatic valve

The appliance is suited to operation with a thermostatic valve.

4. Operation

The heating system of the appliance starts automatically and heats 

the water as soon as you open the DHW valve at the tap.

Setting the DHW temperature

Should the outlet temperature fail to reach the required level with 

the draw-off valve fully open, then more water flows through the 

appliance than can be heated by the heating system.

f

Reduce the flow rate with the draw-off valve.

Outlet capacities

Subject to season, different maximum mixed water or outlet ca-

pacities can result from varying cold water temperatures (see 

chapter “Specification”).

Following an interruption of the water supply

See chapter “Restarting”

5.  Cleaning, care and maintenance

f

Never use abrasive or corrosive cleaning agents. A damp 

cloth is sufficient for cleaning the appliance.

f

Check the taps/valves regularly. You can remove limescale 

deposits at the tap outlets using commercially available des-

caling agents.

6. Troubleshooting

Fault

Cause

Remedy

The appliance will not 

start in spite of a fully 

open DHW valve.

There is no power. 

Check the fuse/MCB in 

your fuse box/distribu-

tion panel.

Starting volume is not 

achieved. The jet control-

ler in the tap or shower 

head is scaled up or con-

taminated.

Clean and/or descale the 

jet controller or shower 

head. 

The water supply has 

been interrupted. 

Vent the appliance and 

the cold water inlet line 

(see chapter “Commis-

sioning/ Restarting”).

Cold water flows briefly 

while hot water is being 

drawn.

The air sensor detects air 

in the water and briefly 

switches the heater off.

The appliance restarts 

automatically after 

1 minute.

If you cannot remedy the fault, notify your heating contractor. To 

facilitate and speed up your enquiry, please provide the serial 

number from the type plate (000000-0000-000000):
