Brief description

The Stiebel Eltron DHC instantaneous
water heater is a hydraulically-controlled
pressure unit for heating cold water, with
which one or more water taps can be
supplied; see Table 2.

Installation location

The unit is suitable for the
preparation of hot water (potable
water supply), and is to be installed as far
as possible in unvented areas free of the
risk of freezing, as close as possible to
the water tap (dismantled units are to be
stored so as to be free of any risk of
freezing, since there will always be
residual water left in the unit).
The DHC unit is to be installed
vertically, in accordance with Fig. 4.
Under-sink installation:
DHC 3 U, DHC 6 U, and DHC 6 S.
Over-sink installation:
DHC 3, DHC 4, DHC 6, DHC 6 S and
DHC 8.
Regulations and provisions
– Regulations issued by local energy supply
companies.
– Regulations issued by the water supply
companies concerned.
Other data to be taken into
account:
– Currently-applicable data on the unit
rating plate.
– Technical data.
– Install the unit flush with the wall.
– Piped supplementary heating is not
permissible.
– Water installation material:
Cold water pipe:
Steel or copper
Hot water pipe:
Copper.
– Electrical connection to permanently-
installed leads (except for DHC 3 U with
connection lead).
– The unit must be capable of being
isolated from the mains supply, e.g. by
fuses, with a minimum isolation path of
3 mm.
The unit must be connected to the
safety earth terminal (see Fig. 14).
– Fittings for open units are not permitted.
– Safety valves are not required.
