2 Installation instructions

Install the floor-standing water heater as described in the illustrated

section. Observe the instructions in the text.

The illustrations can be found at the end of the instruction manual.

2.1 Installation

For economic reasons the installation location should be near the most

frequently used tap connection.

2.1.1 Description of the appliance

The interior of the steel tank has been specially enamelled to prevent

corrosion and has been fitted with a protective anode. The exterior has

been directly insulated with foam which cannot be removed. Cover the

appliance with the supplied protective jacket only when the installation

work is complete.

The universal flange enables electrical connections for single or double

circuit operation. Circulation pipes should be avoided on account of the

high heat losses. The circulation connection is located where the thermal

insulation is noticeably indented.

• Comply with DIN 1988 and the regulations issued by the water

company.

Materials for cold-water and hot-water pipes

Water pipe made of steel, copper or plastic.

If plastic pipes are used, only install pipe systems made of crosslinked

polyethylene (high-density polyethylene) according to DIN 16893 series

2 (20 bar), checked in accordance with DVGW work sheets W 531 and

W 532 with the corresponding DVGW mark of conformity.

Information regarding the suitability and quality of other plastic pipes

without the above-mentioned design approval information can only be

provided by the pipe manufacturer.

Copper pipes are recommended if there is a risk of corrosion.

If using copper and steel materials, they must be joined in the following

sequence, as seen from the flow of direction: Copper comes after steel.

This will avoid corrosion by local cell formation.

Stipulated combinations:

• Cold-water pipe made of copper: hot-water pipe made of copper or

plastic

• Cold-water pipe made of steel: hot-water pipe made of steel, copper

or plastic

• Cold-water pipe made of plastic: hot-water pipe made of steel,

copper or plastic

Pressure reducing valve

The floor-standing water heater is designed to operate at pressures not

exceeding 0,6 MPa (6 bar). A pressure reducing valve must be situated

in the cold-water pipe if the water mains pressure exceeds 0,5 MPa (5

bar). If the water mains pressure exceeds 1,0 MPa (10 bar), a second

pressure reducing valve must be connected in series.

4 Non-return valve

5 Outlet valve

6 Safety valve

7 Through-way shutoff valve

8 Test connection piece for manometer

9 Test valve

10 Pressure reducing valve

(only when water supply pressure exceeds 0,5 MPa (5 bar))

11 Cold-water inlet

The fittings and safety devices indicated in the diagram must be used for

the installation and they must be fitted in the sequence shown

(see DIN 1988 or local regulations).

For easier installation we recommend the use of our compact safety

valve units.

If a central battery (thermostat battery) is used, a device must be fitted

directly to the hot-water outlet of the floor-standing water heater,

in order to measure the cut-out temperature.

Electrical connection (Fig. 5 )

• Electrical installation must only be carried out by an electrician from

the power supply company.
