WARNINGS
This device can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the device in a safe way and understand the
hazards involved.
Children should not play with the device.
Cleaning and user maintenance shall not be performed by children without supervision.
Installation should be carried out in accordance with the valid regulations and according to the
instructions of the manufacturer and by qualified staff.
In a closed-circuit, pressurised system, it is obligatory to install a safety valve with a maximum
nominal pressure indicated in the technical data, preventing the pressure in the tank from
exceeding the nominal pressure by more than 0.1 MPa (1 bar).
The outlet of the safety valve should be installed facing downwards and in a non-freezing area.
To ensure proper functioning of the safety valve, the user should perform regular controls to
remove limescale and make sure the safety valve is not blocked.
Do not install a stop valve between the buffer tank and the safety valve, because it will impair
the pressure protection of the buffer tank!
A buffer tank that is connected to the heating system increases the volume, which has a
significant impact on the size of the expansion tank, which is obligatory and the volume of
which must be properly calculated by a professional.
If the system has to be switched off, please drain any water from the buffer tank to prevent
freezing.
If you are planning to build in an electric heating package, the safety of operation is guaranteed
only if an original heating package is installed.
Please do not try to fix any defects of the buffer tank on your own. Call the nearest authorised
service provider.
Our products incorporate components that are both environmentally safe and harmless to
health, so they can be disassembled as easily as possible and recycled once they reach their
final life stage.
Recycling of materials reduces the quantity of waste and the need for production of raw
materials (e.g. metals) which requires a substantial amount of energy and causes release of
harmful substances. Recycling procedures reduce the consumption of natural resources, as
the waste parts made of plastic and metal can be returned to various production processes.
For more information on waste disposal, please visit your waste collection centre or the store
where the product was purchased.

Dear customer, thank you for purchasing our product.
PRIOR TO THE INSTALLATION AND USING THE BUFFER TANK FOR THE FIRST TIME,
PLEASE READ THESE INSTRUCTIONS CAREFULLY.
This buffer tank has been manufactured in compliance with the relevant standards and tested by the relevant authorities. Its basic
technical characteristics are indicated on the label located on the protective cover.
The buffer tank must be installed and connected by a qualified professional. Interventions within the tank may only be done by an
authorised service provider.
The buffer tank was specially developed for the storage of hot or cold water for heating within the limit temperatures and pressure, in
accordance with the data indicated in the “Technical Properties” chapter. Using the appliance in any other way would be inappropriate
and dangerous. NOT SUITABLE FOR POTABLE WATER.
STORAGE AND TRANSPORT
The buffer tank must be stored in a dry and clean space. Exposure to the elements may damage the appliance.

INSTALLATION
Place the buffer tank in a dry space free from freezing conditions. If possible, it should be placed near other heating sources. The
appliance must be installed by a properly qualified person in accordance with the instructions and local regulations.
The buffer tank may be used in heating and cooling systems. The primary purpose of the buffer tank is storage of superfluous energy,
but it can also be used as a hydraulic switch in heating or cooling systems.
The buffer tank was designed, manufactured and tested for the storage of hot or cold water within the scope of the limit temperatures
and pressure, indicated in the chapter “Technical Characteristics of the Appliance”. Using the appliance in any other way would be
inappropriate and dangerous.
Make sure to leave enough space around the buffer tank for undisturbed regular and irregular maintenance interventions (access to
sensors and connections, cleaning, deaeration etc.).
It is recommended to install a magnetic and mechanical debris filter in order to ensure long-lasting functioning of the system.

FILLING AND STARTING UP YOUR BUFFER TANK FOR
THE FIRST TIME
The first filling and start-up must be performed by a properly qualified person. Before filling the buffer tank with water, the pipes and
the tank must be rinsed to remove any debris and impurities. Upon start-up, pressure test must be performed and the sealing of joints
must be checked. If the tank will be used in a cooling system, make sure the water temperature is always above freezing point. To
prevent corrosion in the system, it is recommended to treat the water properly.

CONNECTING THE ELECTRIC HEATING PACKAGE
(FOR FLOOR-STANDING VERSION ONLY)
The buffer tank may be upgraded with an original electric heating package (heating element, thermostat with a fuse, signal light) to
the designated connection G1 1/2.
The heating package must be installed by a properly qualified person. Installation details are described in the instructions enclosed
with the heating package.
MAINTENANCE
The exterior of the buffer tank should be cleaned with a soft cloth and mild liquid detergents. Do not use detergents that contain
abrasives. Regular maintenance interventions include the inspection of the expansion vessel, safety valves and other valves,
although they are not part of the appliance.
WE RESERVE THE RIGHT TO MAKE CHANGES THAT DO NOT AFFECT THE FUNCTIONALITY OF THE APPLIANCE.
