3.5 Installation location

! Install in a vertical position; see
! In an area not subject to the risk of
freezing.
! Install close to the water tap.

3.6 Unit installation

! Fit the suspension bracket.
Select the securing material to suit the
strength of the wall. With SHZ 120 LCD
and SHZ 150 LCD, two suspension
brackets are required.
Any unevenness in the wall is to be
compensated for by the spacer elements
C
provided (a. approx. 5 mm thick).
! Suspend the unit.
! Push the cover caps onto the suspension
bracket (b).
3.7 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
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
G
heaters are to be used.
– Before connecting the fitting the water
pipe must be thoroughly flushed through.
– Each time heating takes place, expansion
water will drip out of the drain.
– For use, installation, first start-up, and
maintenance, the same instructions apply
as for the operation of unvented
(pressurized) water heaters.
