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
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.
