Before using the heater, please read the instructions carefully. In the future 

it will benefit by its failure-free operation for a long time.

Flow water heaters series POW-LCD MULTI are intended for heating tap water. They can sup-

ply hot water to several water outlets located in different rooms. These heaters are equipped 

with heating coils which are directly washed by water. Such direct process of heating prevents 

scale formation and ensures high efficiency and speed of heating water. The microprocessor 

system analyses the temperature of inlet and outlet water, the set temperature, and water 

consumption of the user. Based on the collected data, it increases or decreases the heating 

power in such a way that the water temperature at the outlet corresponded to the temperature 

set by the user. Such control of the heater operation ensures the comfort of use and energy 

saving. Additionally, the heater is equipped with the possibility of choosing rated power. It is 

equipped with air lock sensors which limit, to the minimum, the possibility of damage of the 

heating elements due to air locking of the water distribution system, as well as the system 

adjusting the temperature drop caused by the drop of supply voltage.

Heaters can additionally heat water that was pre-heated, e.g. with the use of the solar system 

which at the heater inlet cannot exceed 60

O

C.

•  The device cannot be installed in rooms in which the temperature may 

fall below 0

O

C and in which there is the risk of explosion.

•  This equipment is not intended to be used by persons (including chil-

dren) of lower physical, sensory or mental capability, unless they operate 

it under supervision.

•  Attention should be paid to children not playing with the equipment.

Installation instructions 

The installation and start-up of the POW-LCD MULTI heater should be done by a person 

qualified in accordance with the guidelines contained in the Manual. All installation works 

should be carried out with disconnected power and water supplies. The heater electrical instal-

lation should be conducted in accordance with the binding regulations. The device should be 

permanently connected to electrical wiring with ground terminal. The electrical wiring should 

be equipped with residual current circuit breaker protecting against electric shock and with a 

switch ensuring the disconnection of the device from the power source, in which the distance 

between the contacts should be not less than 3 mm.

1.   To the place in which the heater is to be installed lead electrical wiring and water distribu-

tion system, using for that the mounting template.

2.   Drill holes and mount expansion plugs.

3.   Install the control valve with a filter on cold water supply (Fig. 3).

4.   Unscrew the fastening screw which holds the housing of the heater located at the bottom 

of it (Fig. 1), take off the cover and disconnect the ribbon cable by taking the plug out of 

the socket marked “LCD” (Fig. 2).

5.   Select rated power by transferring the link to a proper place on a contact marked MOC 

according to the description on the sticker. 

6.   Screw the heater to the wall with the use of fastening screws, having earlier run the power 

cable through the hole.

7.   Check the starting of pressure switch.
