Brief description

This hydraulically regulated instantaneous water heater is a pressure device for the heating of cold water to 
DIN 1988 that can supply one or several draw-off points. 

The PinControl throughput control unit compensates for fluctuations in pressure and thus achieves largely 

stable฀temperatures.฀The฀PinControl฀limits฀the฀throughput฀and฀thus฀ensures฀a฀suficient฀rise฀in฀the฀DHW฀

temperature - even in winter.
The hydraulic control system regulates the electrical output automatically in two output stages, subject to the 

throughput฀(see฀Table฀2฀"Speciication").

The bare wire heating system is enclosed within a pressure-tested plastic jacket. The heating system is also 
particularly suitable for water with low limescale or with limescale content (see Table 3 "Application areas").

2.3 

Important information

•฀

Air in the cold water supply can destroy the bare wire heating system inside the equipment or can trip 

the safety system. If the water supply to the instantaneous water heater has been interrupted, e.g. 
because of a risk of frost or work on the water system, take the following measures prior to taking the 
equipment back into use:

1.฀ Remove฀fuses฀or฀trip฀the฀appropriate฀MCBs.
2.฀ Repeatedly฀open฀and฀close฀a฀tap฀downstream฀of฀the฀equipment฀long฀enough฀to฀vent฀all฀air฀from฀

the equipment and its cold water supply line upstream.

3.฀ Replace฀the฀fuses฀or฀reset฀the฀relevant฀MCBs.

•฀

Taps/valves

–  Direct draw-off tap for instantaneous water heater ADEo 70 WD - mono-lever mixer with bath/ 

฀ hand฀shower฀changeover,฀part฀no.฀18฀39฀34.

–  Installation with commercially available mains pressure taps is possible. 
–  Thermostatic pressure valves must be suitable for hydraulically controlled instantaneous water 

฀ heaters฀(see฀also฀note฀"1.6฀Recommended฀adjustment฀of฀taps/valves").

Note:

In order for the starting volumes (see Table 3) of stages I and II to be reached safely, pressure losses from 
the instantaneous water heater, tap/valve, hand shower, shower hose and pipework must be taken into 
account during installation. 
Typical pressure losses for a shower water volume of 10 l/min:

–  Mono level mixer 

0.04 - 0.08 MPa

–  Thermostatic valves 

03 - 0.05 MPa

–  Hand shower 

0.03 - 0.15 MPa

•฀ Always฀carefully฀observe฀all฀information฀in฀these฀operating฀and฀installation฀instructions.฀These฀contain฀

important information regarding safety, operation, installation and maintenance of this equipment.
