1.1 Unit description

The 

SHW 200 - 400 S

 floor-standing water

heater can provide hot water to suit

requirements up to about 80 °C and supply

one or more draw-off points. The water is

heated electrically.

•

Stepless temperature adjustment possible

from about 35 °C to about 80 °C 

A

(

1

).

If required, the hot water temperature

limitation set at the works (60 °C) can be

altered by the qualified installer at the

electrical heating element 

G

.

•

The water content is heated to the preset

temperature in accordance with the

operating mode.

Single-circuit operation:

Automatic reheating takes place as a

function of the electricity supply.

Dual-circuit operation:

In this operating mode the appliances

provide basic heating, which automatically

heats up the water content during off-peak

periods.

Rapid heating can be switched on if

required by pressing the button (

3

). Once

the preset temperature has been reached,

the rapid heating mode will be switched

off, and not switched on again.

•

The time required for heating up depends

on the cylinder content, the temperature

of the cold water, and the heating capacity.

See the diagram 

B

 for the heating-up

time at a setting of 60 °C (

E

) and a cold

water temperature of 10 °C.

I

= approx. 40 °C

E

= approx. 60 °C (recommended

energy saving setting, low

limescale formation)

III

= approx. 80 °C (maximum settable

temperature).

The temperatures may deviate from the

reference values given due to the

particular features of the individual

system.

1. Operating instructions 

for the user and qualified installer

1.3 Safety instruction

A hot water temperature of more

than 60 °C may occur at the draw-

off fitting.

Accordingly, keep small children away

from the fittings. 

Risk of scalding!

1.4 Important instruction

•

Arrange for the floor-standing water heater

and the safety group to be checked

regularly by a qualified installer.

•

The appliances are under water mains

pressure. During heating, expansion water

will drip out of the safety valve. If water

continues to drip after the heating phase

has ended, please inform your qualified

installer.

•

The steel cylinder is fitted on the inside

with a special enamel coating to protect it

against corrosion, and also has a protective

anode with a wear display (signal anode).

Once the signal anode has worn away,

moisture will pass to the display element

(

4

) and cause it to change colour.

If the display element (

4

) turns red,

please inform your qualified installer

so that he can check the signal anode and

replace it if necessary.

Risk of freezing

At the temperature selection setting 

!

 (=

cold), and under voltage supply, the appliance

is protected against freezing, but not the cold

water feed pipe or the water mains pipe.

1.5 Trouble-shooting

See 

„3. Fault elimination - User“

1.6 Care and maintenance

Maintenance work, such as checking

the electrical safety, may only be

carried out by a qualified installer.

•

At high temperatures almost all water

precipitates limescale. This forms deposits

in the appliance and affects its function and

service life. The heating elements must

accordingly have the limescale removed

from time to time.

The qualified installer, who is familiar with

the quality of the local water, will advise

you of the time for the next maintenance

inspection.

•

A damp cloth is sufficient for caring for the

plastic components. Do not use any

abrasive or scouring cleaning agents.

1.7 Instructions for

installation and use

Keep these instructions in a safe

place, and give them to the next user

in the event of a change of ownership. In

the event of any maintenance or repair

work being required, provide them to the

qualified installer for his reference.
