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. This anode

protects the inside of the cylinder from corrosion. 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.

Single circuit operation

The appliance automatically heats up at any temperature setting subject

to the availability of power.

Dual circuit operation

During off-peak tariff periods (cheap rate periods of power supply

utilities), the appliance automatically heats up the water content with

standard heating output at any temperature settings. In addition, you

can start the booster heater during peak tariff periods.

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.
