2.2 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 sufficient 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 "Specification").
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
– Thermostatic valves
– Hand shower
• Always carefully observe all information in these operating and installation instructions. These contain
important information regarding safety, operation, installation and maintenance of this equipment.
