Before using the heater please read the instructions carefully. In the future it will pay off in
the form of failure-free operation for a long time. Flow water heaters series POW 12, 18,
21, 24 with two-degree hydraulic switch are designed for heating utility water. Warm water
can provided to a couple of water drawing points located in different rooms. These heaters
are equipped with heating spirals that are directly washed by water. This direct heating
process prevents limescale from settling and ensures high efficiency and quick heating of
water. Microprocessor system analyses the inlet water temperature and the temperature set
by a user, as well as its consumption. Based on collected data, it increases or decreases
heating power in such a way that the temperature of water at the outlet corresponded to
the one set by the user. In addition, the electronic system of the heater is equipped with
an air block sensors that decrease to the minimum the possibility of damaging immersion
heaters due to air blocking of the water supply installation. POW heaters may heat up water
that was initially heated, for example by the solar heating installation, which at the inlet of
the heater cannot exceed 60
O
C.
■ The device cannot be installed in rooms in which temperature may
fall below 0°C, as well as in which there is a risk of explosion.
■ This equipment is not designed to be used by persons (including
children) of the limited physical, sensory or mental fitness, unless
their use is supervised.
■ Attention must be paid to children so that they would not play with
the device.
Instructions for assembly
Installation as well as start-up of the POW heater should be done by an authorized person
in accordance with the instructions included in the Instructions. Any installation works
should be done with disconnected power and water supply. Electric installation of the heater
should be made pursuant to the binding regulations. The device should be permanently
connected to an electrical installation with an earth terminal. Electrical installation should be
equipped with a residual circuit breaker with the protection against electric shock, as well
as a breaker ensuring the disconnecting of the device from the source of power supply in
which the distance between contacts should be not less than 3 mm.
1. To the place in which the heater is to be installed, electrical as well as water installation
should be supplied using the assembly template for that.
2. Drill holes and insert expansion plug.
3. After supplying cold water, install the control valve with a filter (pict. 3).
4. Unscrew the located at the bottom of the heater casing screw fastening the casing
(pict. 1), take off the cover and disconnect the belt cable by taking out the plug from
the socked marked “DISPLAY” (pict. 2).
5. Screw the heater to the wall with the fastening screws, having previously led the supply
cable through the hole.
6. Check the turning on of the pressure switch.
7. Remove blanking plugs from water connections.
