INSTALLATION
7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability
only if the original accessories and spare parts intended for the
appliance are used.
7.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
7.3 Water connection and safety assembly
Note
Carry out all water connection and installation work in
accordance with regulations.
The cylinder must be connected with water inlet and outlet pipes
made from metal. Other metal parts of the cylinder that can be
touched and that are in contact with water must be permanently
and reliably connected with the earth conductor.
The max. permissible pressure must not be exceeded (see chapter
"Specification / Data table" and cylinder specification).
f
f
Install a type-tested safety valve in the cold water supply
line. For this bear in mind that, depending on the static pres-
sure, you may also need a pressure reducing valve.
f
f
Size the drain so that water can drain off unimpeded when
the safety valve is fully opened.
f
f
Fit the discharge pipe of the safety valve with a constant
downward slope and in a room free from the risk of frost.
f

The safety valve discharge aperture must remain open to the
atmosphere.
8. Appliance description
8.1 Standard delivery
Delivered with the appliance:
- Cable entries (supplied as loose parts depending on the ap-
pliance type)
- Fixing screws, corrugated washers
8.2 Accessories
Required accessories
Depending on the static pressure, safety assemblies and pressure
reducing valves are available. These type-tested safety assemblies
protect the appliance against unacceptable excess pressure.
Further accessories
A mating flange is available as an accessory.
9. Installation
Note
For the installation of the appliance, the cylinder must
be fitted with a mating flange (see chapter "Appliance
description / Accessories").
Note
The control panel must not be thermally insulated to pre-
vent any excessively high temperatures from occurring
inside the control panel.
The condensate aperture in the flanged control panel
must remain open while the cylinder is thermally insulat-
ed so that any condensate that occurs can drip off freely.
f
f
Observe the required torque values during installation (see
chapter "Specification / Data table").
f
f
Always install the appliance horizontally with the cable en-
tries facing downwards.
f
f
Always install the appliance with heating elements and a
protective pipe arranged in parallel. For this, use the screws
supplied. Realign the components where necessary.
