2.2 Fittings
• Unvented (pressurized) mode of opera-
tion: Safety groups kV 30 or kV 40 F .
• Vented (pressureless) mode of operation:
Fittings without pressure G .
2.3 Regulations and
provisions
• The installation (water and electrical
installation) and first start-up, as well as the
maintenance of this unit may only be
carried out by an approved specialist
installer in accordance with these
Instructions.
• Perfect function and operational safety are
only guaranteed with original accessories
and spare parts intended for the unit.
y The installation should be carried out in
accordance with the relevant water
(WRAS) and electrical (IEE) guidelines and
regulations.
y Installation should be carried out in
accordance with the relevant water and
electricity supply companys regulations.
The following are also to be respected:
• The unit rating plate
• Technical data
• Water installation
Pipe material:
– Cold water pipe – Hot water pipe
Copper pipe Copper pipe
Steel pipe Steel or copper 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.
– The unit must be capable of all-pole
disconnection from the mains, for
example by fuses, with an isolating
distance of at least 3 mm.
2.5 Installation location
• In an area not subject to the risk of
freezing.
• Install close to the water tap.
2.6 Unit installation E
• 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 D .
• Push the cover caps onto the suspension
bracket E (b).
2.7 Water connection
• Unvented (pressurized) for the
supply of several draw-off points.
– Install the type-tested safety groups F
KV 30, Order No. 00 08 26, up to
0.48 MPa water pipe pressure
KV 40, Order No. 00 08 28, up to 1 MPa
water pipe pressure
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.
00 34 66 (order separately), also
possible in conjunction with KV 40.
– 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
the choke of the safety group.
• Vented (pressureless) for the supply
of one single draw-off point
The units are suitable for vented
(pressureless) operation mode.
Do not block off the drain and
fittings pivot arm.
– With this installation the Stiebel Eltron
fittings for vented wall-mounted water
heaters
G are to be used.
– Before connecting the fitting the water
pipe must be thoroughly flushed through.
– For use, installation, first start-up, and
maintenance, the same instructions apply
as for the operation of unvented
(pressurized) water heaters.
