Dear customer, thank you for purchasing our product.
PLEASE READ THE INSTRUCTIONS CAREFULLY PRIOR TO THE
INSTALLATION AND FIRST USE OF THE WATER HEATER.
The water heater has been manufactured in compliance with the relevant standards. Basic
technical characteristics of the product are listed on the label attached to the protective
cover.
The installation of the water heater must be carried out by qualified staff only. All repairs and
maintenance work in the interior of the water heater as well as limestone removal or testing/
replacement of the corrosion protection anode may only be carried out by an approved
maintenance service provider.
The hot water tank is designed in a manner which allows using the following heating sources,
via heat exchanger:
− central heating hot-water system
− solar power
− heating pump.
Electric heater type R may be additionally installed on the flange 180mm, or electric heater type
SH to the connecting bushing G 6/4.
INSTALLATION
The heater should be installed in a dry room that is not subject to freezing conditions,
preferably in the vicinity of other sources of heating (e.g. boiler room).

On the rear side of the hot water tank there are special channels (H1, H2) for mounting the
feelers for regulation of the system connection of the hot water tank to other heating sources.
Access to the channels is under the covering joint of the protective covering, approximately
in the middle of the tank height.
Insert the feeler into the channel and fix it with the enclosed rubber tap. Recommended
position (h1, h2) of the feeler is marked on the drawing:
- If the feeler is mounted higher than recommended, the thermostat will react too fast,
the operating time of the circular pump will be shorter and the difference between the
temperature in the hot water tank and heating media after the thermostat switch off will be
higher. This means that the quantity of water in the hot water tank and its temperature will
be lower,
- If the feeler is mounted lower than recommended, the operating time of the circular pump
will be longer and the difference between the temperature in the hot water tank and
heating media after the thermostat switch off will be lower. This means that the quantity of
water in the hot water tank and its temperature will be little higher.

CONNECTION TO THE WATER SUPPLY
Before connecting the hot water tank, install the protective covering. Take off the top cover
and insert the covering, make sure the slots on the covering match the connections on the
hot water tank. Zip the zipper from top to bottom and tighten the tapes on the top edge of the
covering. Replace the top cover. Insert the thermometer into the prefabricated sleeve on the
front of the hot water tank; make sure to cut the opening for the sleeve into the covering. The
connection to water supply network and fastening of the coloured rosettes shall be made
according to the markings defined in previous Section.
For safety reasons the supply pipe must be fitted with a return safety valve that prevents the
pressure in the tank from exceeding nominal pressure by more than 0.1 MPa. The heating of
water in the heater causes the pressure in the tank to increase to the level set by the safety
valve. As the water cannot return to the water supply system, this can result in dripping from
the outflow of the safety valve. The drip can be piped into the drain by installing a catching
unit just below the safety valve. The drainpipe fitted under the safety valve outflow must be
piped down in a straight vertical line and located in an environment free from the onset of
freezing conditions.
In case the existing plumbing does not enable you to pipe the dripping water from the return
safety valve into the drain, you can avoid the dripping by installing expansion tank on the
inlet water pipe of the boiler. The volume of the expansion vessel shall be at least 3% of the
volume of the hot water tank.

3. Non-return valve
4. Pressure-reducing valve

7. Funnel outlet to the drain
8. Drain valve
H - Cold water
T - Hot water
The water heater may be connected to the household water supply system without a
pressure-reducing valve provided the supply mains pressure is less than 0.5 MPa.
In case of the mains pressure exceeding 0.5 MPa, a pressure-reducing valve must be
installed to ensure that the pressure on the supply side of the heater does not rise above the
nominal value.

CONNECTION TO ALTERNATIVE SOURCES OF HEATING
The heaters enable the water for sanitary use to be heated by alternative sources of energy
(e.g. central heating, solar power, …) by installing one or two heat exchangers.
Additionally, a heating pump may also be fitted to the side flange of the tank.
Options for connecting the water heater to various sources of heating are shown in the
drawings below.

OPERATION AND MAINTENANCE
The water heater is ready for use once it has been connected to water and other sources of
heating.
The usual main sources of heating of water for sanitary use are central heating or solar
power; in this case any regulation of water heating is performed in the heating system.
Electric heater type R may be additionally installed on the flange 180mm, or electric heater type
SH to the connecting bushing G 6/4, which are used for additional heating of water:
- If you need higher temperature of water than assured by other heating sources,
- If due to seasonal or other conditions there are no main heating sources.
In case of exposure to sub-zero temperatures, the water should be thoroughly drained from
the heater before the onset of freezing conditions.
Once that is done, open the hot water tap on one of the mixer taps connected to the water
heater. The water from the water heater drains by way of the drain valve on the inlet pipe.
External parts of the water heater may be cleaned with a mild detergent solution. Do not use
solvents and abrasive cleaners.
Regular preventive maintenance inspections ensure faultless performance and long life of
your heater. The first of these inspections should be carried out by an authorised maintenance
service provider about two years from the date of installation in order to inspect the wear
of the corrosion protection anode and to remove any limestone as required. Build-up of
limestone is a product of quality, quantity and temperature of water flowing through the water
heater. While inspecting the heater, the maintenance service provider will also recommend
the date of the next inspection.
Wear of the corrosion protection anode is carried out visually. Replacement is required when
the inspection reveals that the anode diameter has been substantially reduced or worn all
the way to the steel core.
Tank warranty is subject to regular inspections of the protective anode.
In the event of the water heater breaking down, you are kindly requested to contact
the authorised maintenance service provider located closest to you. Please do not
attempt to repair the unit yourself.
