2. Installation instructions

 for the qualified installer

2.3 Brief description

The hydraulically controlled, pressurized 
Mini-Instantaneous Water Heater DHM is 
designed to supply warm water for one tap 
only.

The unit is suitable for hand wash basins, for 
example in guest WC’s, and for under-sink and 
over-sink installation.
The bare-wire heating system is suitable for 
low-lime and limy water (see Table 2 for 
ranges of use).

2.4 Fittings

Use only pressure tap fittings!

Please use jet regulator 

A

 (

or

) depen-

ding on the type of DHM in question).

1.4 Safety instruction

In the case of temperature selection, 
water temperatures of over 60 °C 

can be reached at the hot water outlet. 
Small children should therefore be kept 
away from the hot water outlets.

Danger of scalding!

1.5 Important notes

If the water feed of the DHM has 
been interrupted - e.g. because of the 

danger of frost or work on the water pipe, 
the following steps must be taken before 
the unit is brought back into operation:
1. Remove or switch off fuses.
2. Open a tap downstream of the unit until 

the unit and the cold water feed pipe are 
free of air. 

3. Replace or switch on fuses again. 

1.6 Maintenance and care

Maintenance work, such as for ex-
ample checking the electrical safety, 

may only be carried out by a qualified 

installer.

A damp cloth is sufficient for care of the unit. 
Do not use any abrasive or corrosive cleaning 
agents.
Please de-scale or replace the enclosed jet 
regulator „

1.8 Operating and installati-
on instructions

Keep these instructions carefully and 
pass them on to your successor in 

the event of a change in ownership, in the 
event of maintenance and possible repair 

work they should be passed to the qualified 

installer for his attention. 

1.1 Unit description

The hydraulically controlled pressurized Mini-
Instantaneous Water Heater is designed to 
heat water for one draw off point. When the 
draw-off fitting is opened, the heating capacity 
switches on automatically and the water is 
heated. The hot water output is dependent on 
the cold water temperature, the heating capa-
city, and the flow rate.

1.2  The most important 
points in brief

Temperature adjustment is effected using 

the fitting:

–  To increase the temperature, restrict 

the flow rate a little.

–  For low temperatures, increase the flow 

rate or m

ix in cold water.

for the user and the qualified installer

2.2 Important information

Air in the cold water pipe will destroy 
the bare-wire heating system of the 

DHM. If the water supply to the DHM has 
been interrupted, for example due to the 
risk of frost or work on the water pipe, the 
following steps must be carried out before 
the system is used again:
1.  Disconnect supply or disconnect the 

fuses.

2.  Open a hot water tap downstream of 

the device for as long as it is necessary 
for the device and the cold water pipe 
to be freed of air.

3.  Reconnect the supply or connect the 

fuses again.

–  All information in these Instructions for 

Use and Installation must be followed 
carefully. They provide important infor-
mation with regard to safety, operation, 
installation, and maintenance of the de-
vice.
