3 Product description

3.1 Product designation

This product is an electric instantaneous

water heater.

The hydraulically controlled small instant-

aneous water heater heats the domestic

hot water directly at the draw-off point.

The domestic hot water heating element

starts automatically when the water tap

is opened. An installation with short lines

guarantees minimal heat losses. The avail-

ability of domestic hot water at the draw-off

point depends on the following factors:

–Water temperature at the cold water

connection for the small instantaneous

water heater

–Heating element output

–Flow rate quantity

The bare-wire heating element is suit-

able for various water hardness levels

(hard and soft). This heating element is

not sensitive to scale deposition.

The heating element guarantees fast and

efficient domestic hot water generation

at the sink. Installing the enclosed flow

regulator guarantees an optimum jet of

water.

3.4 CE marking

The CE marking shows that the products

comply with the basic requirements of the

applicable directives as stated on the de-

claration of conformity.

The declaration of conformity can be

viewed at the manufacturer's site.

4 Operation

4.1 Switching on the product

Danger!

Risk of scalding caused by

hot water

During operation, the domestic

hot water temperature can

reach 50 °C and above. As of

a domestic hot water temper-

ature of 43 °C, there is a risk of

scalding.

▶We recommend operating

the product with a filter at the

cold water connection and

a flow regulator at the water

tap for the draw-off point.

▶Only start up the product once the cas-

ing has been completely closed.

▶Open the valve and/or activate the

sensor for the valve with infrared detec-

tion. The domestic hot water heating

element starts automatically. The tem-

perature can be adjusted at the valve.

▶You can find the required minimum flow

rate for starting the heating element

in the technical data in the installation

instructions.

4.2 Increasing the water

temperature

Condition: Even though the tap is set to the max-

imum temperature, the water temperature is too low

for you.

▶Decrease the flow rate at the tap.

4.3 Lowering the water

temperature

Condition: Even though the tap fitting has been set

to the minimum temperature, the water is too hot.

▶Increase the flow rate quantity at the

tap fitting or increase the cold water

volume.

5 Eliminating faults

Danger!

Risk of death caused by im-

proper repair work

▶If the power supply cable is

damaged, never replace this

yourself.

▶Contact the manufacturer,

customer service or a simil-

arly qualified person.

8Operating instructions 0020323584_00

Danger!

Risk of electric shock

If there are faults or leaks, there

is a risk of electric shock.

▶Earth the product.

▶If a fault occurs, use the par-

tition that is installed on-

site (e.g. fuses or power

switches) to disconnect the

product from the power sup-

ply.

▶In the event of a leak at the

unit, close the cold water

supply immediately.

▶Have the fault eliminated

by customer service or a

competent person.

▶Use the table in the appendix to elimin-

ate the faults. (→Page 10)

▶If you are unable to eliminate the fault,

contact your competent person.

6 Maintenance

Availability, safety, reliability, and the ser-

vice life of the product can only be guar-

anteed by carrying out regular inspections.

The inspection may require maintenance

to be carried out earlier, depending on the

results.

6.1 Caring for the product

▶Clean the casing with a damp cloth and

a little solvent-free soap.

▶Do not use sprays, scouring agents,

detergents, solvents or cleaning agents

that contain chlorine.

6.2 Cleaning/checking the flow

regulator

1. Unscrew the terminal (1) for the water

tap.

2. Regularly check the flow regulator for

the water tap at the draw-off point in

order to clean or, if required, replace

it.

3. Each time you replace the flow regu-

lator (2), also replace the seal (3).

6.3 Cleaning/checking the draw-off

point

▶Regularly descale the draw-off point

using commercially available agents in

order to remove any scale depositions.

6.4 Procuring spare parts

The original components of the product

were also certified by the manufacturer as

part of the declaration of conformity. If you

use other, non-certified or unauthorised

parts during maintenance or repair work,

this may result in the product no longer

meeting the applicable standards, thereby

voiding the conformity of the product.

We strongly recommend that you use ori-

ginal spare parts from the manufacturer as

this guarantees fault-free and safe opera-

tion of the product. To receive information

about the available original spare parts,

contact the contact address provided on

the back page of these instructions.

0020323584_00 Operating instructions 9

▶If you require spare parts for mainten-

ance or repair work, use only the spare

parts that are permitted for the product.

6.5 Checking the product

▶Check during maintenance:

–Abnormalities on the product.

–The cleanliness of the water filter in the

cold water connector.

–The leak-tightness of the supply lines.

The electrical installation of the product

must only be checked by a qualified elec-

trician.

If the cold-water filter is dirty or damaged,

it must be cleaned and serviced by a com-

petent person.

7 Decommissioning

▶Disconnect the instantaneous water

heater from the power supply.

▶To have the product permanently de-

commissioned, contact your competent

person.

8 Recycling and disposal

▶The competent person who installed

your product is responsible for the dis-

posal of the packaging.

If the product is labelled with this

mark:

▶In this case, do not dispose of the

product with the household waste.

▶Instead, hand in the product to a collec-

tion centre for waste electrical or elec-

tronic equipment.

If the product contains batteries that

are labelled with this mark, these batteries

may contain substances that are hazard-

ous to human health and the environment.

▶In this case, dispose of the batteries at

a collection point for batteries.
