21 Instructions for installation and use
2.2 Regulations and
provisions
" Installation (water and electrical
installation) of this appliance, taking into
service for the first time, and maintenance
may only be carried out by a qualified
installer, in accordance with these
instructions.
" Perfect function and operational safety can
only be guaranteed if original accessories
and spare parts are used which were
intended for it.
" DIN VDE 0100.
" Regulations and provisions of the local
energy supply utility.
" DIN 1988 / DIN 4109.
" Regulations and provisions of the local
water supply utility.
" The floor-standing water heater must be
secured to the floor.
The following items are also to be
respected:
" The appliance rating plate.
" Technical Data.
" Water installation
Pipe material:
– Cold water pipe – Cold water pipe
Copper pipe # Copper pipe
Steel pipe # Steel or copper pipe
Plastic pipe systems:
Installation also in conjunction with
DVGW-tested plastic pipe systems for
cold and hot water pipes.
Energy Saving Law (ENEG).
– The hot water pipe must be thermally
insulated.
– The hot water temperature in the pipe
network is to be limited by automatic
devices or other measures to a maximum
of 60 °C. This does not apply to raw
water systems which mandatorily require
higher temperatures or a pipe length of
less than 5 m.
– Hot water systems are to be equipped
with automatic devices for disconnecting
the circulation pump. In the case of floor-
standing water heaters with circulation
pipes, the circulation pump is to be
controlled by the installation of a timer
switch and contact thermostats if
necessary.
" Electrical installation
– Electrical connection only to fixed leads
in conjunction with the removable cable
bushing.
– The appliance must be capable of being
isolated at all poles from the mains, e.g.
by fuses, with a circuit sever of at least
3 mm.
2.3 Installation location
" In an area with no risk of freezing.
" Close to the water tap.
2.4 Removing/fitting the
cylinder casing
The cylinder casing is fitted in the condition
as delivered. It can be removed if the need
arises.
Removal:
1. Take off the plastic cover (9)
2. Remove the plastic base panel (5)
3. Draw off the temperature selector switch
(1)
4. Remove the switchbox cap (6) and the
cable bushing (13)
5. Remove the plastic sheathing (7)
Fitting:
In the reverse order to removal.
The sheathing and the cover must be
fitted before the water connection
and before the circulation pipe if this is to
be installed.
The base panel is to be fitted after the
sealing tightness test.
2.5 Water connection
" Flush the pipe through thoroughly.
" Fit the hot water drain pipe.
" Fit the cold water feed pipe D .
The connection pipe can be fitted to
choice between the feet (a). When
screwing them on, use a spanner (b) to
apply counter-pressure. The stability of the
connection pipes is to be checked, and
additionally tightened by the customer if
necessary. If required, the cold water
connection can be fitted directly to the
sockets (c).
" Instal a type-tested safety group, such as
Stiebel Eltron ZH 1, Order No. 07 43 70
up to 0.6 MPa water pipe pressure
(pressure at rest 0.48 MPa). With pressure
at rest > 0.48 MPa, the pressure-reducing
valve DMV/ZH 1, Order No. 07 43 71, is
to be additionally installed.
Circuit layout
E :
a Shutoff valve
b Pressure-reducing valve DMV/ZH 1
(if required)
c Test valve
d Backflow preventer
e Connection for measuring devices
f Drain valve
g Safety valve G 3/4, 0.6 MPa (6 bar)
h Drain
– Plan the dimensions of the drain for a
fully-opened safety valve. The drain
aperture of the safety valve must
remain open to the atmosphere.
– The safety valve drain is to be installed
with a permanent downwards
inclination.
– The information in the Installation
Instructions under „Safety valve“ are to
be taken into account.
" Fill the appliance with water by opening
the hot water fitting and flush it through
thoroughly.
" Carry out the sealing tightness test.
" Note regarding the circulation pipe:
If it is intended that a circulation pipe is to
be installed, the pipe is to be fitted to the
socket (8) (socket for the thermometer is
also possible). To do this, the plastic
sheathing is to be drilled off at the marking
(e.g. with a 70 mm keyhole saw). The
thermal insulation is to be removed
around the socket so that the circulation
pipe can be fitted. To do this, screw in the
connecting piece (19) supplied, then
connect circulation pipework. The
adhesive rosette (20) should be stuck to
the plastic casing, around the pipework
connection.
