• Technical data
• Water installation
Pipe material:
– Cold water pipe
Copper pipe
Steel pipe
Plastic pipe systems with the instantanous
water heater the operating temperature
can be adjusted upto max. 82 °C. The
maximum temperature can be limited to
65 °C. In case of failures temperatures can
rise up to 95 °C (max. 0.6 MPa).
The assigned plastic pipe system must be
appropriate for these conditions.

• Electrical installation

– Electrical connection only with fixed-laid
leads in association with removable
cable bushings.

2.5 Installation location

• In an area not subject to the risk of
freezing.
• Install close to the water tap.

2.6 Unit installation

• Fit the suspension bracket.
Select the securing material to suit the
strength of the wall. With SH 120 S and
SH 150 S, two suspension brackets are
required.
Any unevenness in the wall is to be
compensated for by the spacer elements
provided (a. approx. 5 mm thick).
• Install in a vertical position; see
• Push the cover caps onto the suspension
bracket
2.7 Water connection
• Unvented (pressurized) for the
supply of several draw-off points.
– Install the type-tested safety groups
KV 30, Order No. 00 08 26, up to
0.48 MPa water pipe pressure
– Hot water pipe
KV 40, Order No. 00 08 28, up to 1 MPa
Copper pipe

Steel or copper pipe
a Safety valve
b Backflow preventer
c Test valve
d Throughflow isolating valve (choke)
e Pressure reducer (with KV 40)
f Test nozzle for pressure gauge
g Thermostat fitting TA 260 Order No.
– Establish dimensions for the outflow pipe
for a fully-opened safety valve. The drain
aperture of the safety valve must remain
open to the atmosphere.
– The drain for the safety group is to be
installed with a constant downwards
inclination.
– The information provided in the
Installation Instructions for the safety
group are to be respected.
– Set a maximum flow rate of 18 l/min at
SH 120 S SH 150 S
the choke of the safety group.
