DESCRIPTION AND PRINCIPLE OF WORK
Description of the buffer tank
1.
The buffer tank consists of a body and protective plastic panel.
The body consists of a steel reservoir (water tank) and housing (outer shell) with
thermal insulation placed in-between made of ecologically clean high density
polyurethane foam reducing the heat losses to a minimum.
The steel reservoir is made of black steel.
The galvanic insulation fittings are factory installed on the function connections.
In the event that the pipes of the hydraulic installation are copper or of another
metal other than that of the water container, as well as when using brass
connecting elements, the use of additional galvanic insulation fittings is not
required.

ATTENTION! The heating element is not included in the set of the buffer tank! It
can be purchased by the customer. In case that another heating element is used,
it must be suitable for use in tanks without an internal ceramic coating and with built-in
overheating protection. The technical parameters of the heater must be in accordance
with the maximum operating temperature and the volume of the buffer tank in which it
will be installed. The installation and commissioning of the heating element must be
carried out by qualified electricians and technicians for the repair and installation of the
buffer tanks, who have acquired their legal capacity in the territory of the country where
the installation and commissioning of the appliance are carried out and in accordance
with the statutory and arrangement. If the above conditions are not met, the
manufacturer is not responsible for warranty and post-warranty service of the appliance.

MOUNTING AND SWITCHING ON
Attention! Improper installation and connection of the buffer tank may make it
hazardous for the health and life of consumers. It may cause grievous and permanent
consequences, including but not limited to physical injuries and/or death. Improper installation
and connection of the buffer tank may also lead to damage to the consumers' property /
damage and/ or destruction/, or to that of third persons, as a result of, but not limited to
flooding, explosion and/or fire. Installation, connection to the heating or cooling system, and
putting into operation must be carried out by certified electricians and technical personnel
certified in installation of this category of appliances, who have obtained their license in the
state where the installation and commissioning of the appliance are carried out, and in
compliance with its local legislation.
1.
The buffer tank is affixed to a wall via the mounting brackets attached to the
unit's body. Two hooks are used for suspending the buffer tank (min. Ø 10 mm)
set firmly in the wall. They are not included in the mounting set. The mounting
bracket's construction designed for water heaters intended for vertical mounting
is universal and allows a distance between the hooks of 220 to 310 mm fig. 4a.
Attention! Risk of injury caused by the buffer tank tipping over if it is not
properly fixed to the wall.

faults in the system for providing hot water, the buffer tank must be mounted in
premises outfitted with floor hydro insulation and plumbing drainage.

When installing the buffer tank:
•
Ensure that the water-supply connections can be easily accessed for
61.3
mounting and checks.
•
Ensure that no highly flammable parts come into contact with the

components of the buffer
•
Do not install the product above another unit that may damage it (e.g.,

above a cooker that produces steam and grease) or in a room with a high
level of exposure to moisture or in a corrosive environment.
•

Do not install the buffer tank below a unit from which liquids may flow.
HYDRAULIC INSTALLATION - FIG. 9

Hydraulic connections
1.
Note! The connection of the buffer tank to a system must be carried out
according to a project created by a competent and licensed engineer, executed
by competent technical installers, in accordance with the regulatory requirements
applicable in the territory of the country concerned! The existence of a SUCH PROJECT is
a mandatory condition for the recognition of the manufacturer's warranty!
We recommend the mounting of the buffer tank at close proximity to locations
where hot water is used, in order to reduce heat losses during transportation.
Elements for installation:
Inlet and outlet pipes;
1.1.
Non-return valve.
1.2.
1.3.
Return valve.
Its type should be defined by a legally competent engineers in accordance with
the technical data of the buffer tank, the built system, as well as with local and
European norms.
1.4.
Safety valve.
1.5.
The installation must be protected by a suitably selected pressure relief valve
not higher than the maximum working pressure specified for the system. The
relief valve should be mounted so that the direction of the arrow on its body
corresponds to the direction of water flow. In the case of installation according
to other schemes, a qualified engineers shall calculate and determine the type of
safety
Important! Between the buffer tank and the safety valve there must not be
any kind of stop valves, taps or open expansion vessel. The presence of
other /old/ safety return valves may lead to a breakdown of your buffer tank and
they must be removed.
1.6.
Safety valve drainage pipe.
It should be executed in accordance with local and European safety norms and
regulations! It must have a sufficient slope for the water to run off. The two
ends must be open to the atmosphere and protected against freezing. When
installing the pipe, take safety measures against burns when the valve start
operating.
1.7.
Sewage
1.8.
Drainage tap
1.9.
Flexible drain connection.
1.10.
Expansion vessel.
In the steel reservoir there is no volume to accommodate the expansion of
water due to its heating.
Attention!
Its volume and type must be defined by licensed engineers and have to be in
accordance with the system technical requirements, local and European lows,
standards and technical norms. Its installation shall be carried out by a qualified
technician in accordance with its operating instructions and current legislation
