ABOUT THE COMPANY
MINIB,a.s. is a Czech business through and through, and it ranks
among the leading manufacturers of convectors in the Czech Republic. It currently exports to thirty countries in Europe, Asia, Australia,
and America.
Since 1999, MINIB has been systematically innovating its production technology and its products and has invested considerable sums
in proprietary development and design, with the goal of offering our
customers solutions that are mature both from the technical and esthetic points of view.
MINIB's business is economically soand and the company consistently turns a profi t. This allows us to invest in R&D, technology, and
above all, human capital, so as to ensure our long-term prosperity.
ABOUT THE MANUFACTURING PROCESS
The manufacturing facility is located in Býkev near Mělník and has
excellent transport connections. It is furnished with state-of-the-art
production technology. Most manufacturing operations are carried
out on CNC machines, which allows us to accommodate even the
most sophisticated wishes of our exacting customers.
In response to individual calls for customization, we are able to create a wide variety of non-standard, one-of-a-kind products that satisfy
specifi c needs.
All products are made from high-grade material with a useful life of
many years, which is why we offer a 10-year warranty on heat exchangers and our stainless-steel convector vats.
MINIB holds an ISO 9001:2008 certifi cate in addition to numerous utility models and patents.
The entire range of products is submitted to testing in the independent, accredited test chamber of HEATEST, s.r.o. pursuant to the European Standard EN 442-2, which is why we are able to guarantee the
advertised heating and cooling output.
ABOUT THE PRODUCTS
MINIB's production portfolio consists of over 70 convector types.
Customers can thus choose the right convector for any interior.
The main advantage of convectors is that they are effi cient, modern,
economical, and esthetic heaters suitable for both dry and humid
environments. Signifi cant power savings are achieved thanks to
low water requirements for the immediate heating or cooling of a given area. This leads to low consumption of electricity required for
its heating. In addition to water and energy savings, a great heating
and cooling dynamics is also important. The space saving design is
another important feature of these products. Our convectors do not
disturb interior esthetics, have a modern design, and - last but not
least - are safe thanks to their 12V power supply.
The product range comprises various types of convectors:
FLOOR convectors without fans that work on the natural con-
vection principle. Convectors with fans utilize the principle of
forced convection.
FREE STANDING AND WALL MOUNTED convectors with and
without fans are also available. Heating benches with granite and wooden top panels are available for humid environments (swimming pools, bathrooms).
DESIGN convectors are a unique patent series that use both
the convection and heat radiation principle for heating.
These convectors have aluminum composite front panels
available in a number of modern designs from smooth glass
with various colors or from glass with sand blasted decorations. The company also offers granite front panels.
MINIB can satisfy any individual, non-standard requirements of
its customers such as angular or arc-shaped convectors with
various connections and tailor them to their demands. MINIB
emphasizes high user comfort. All products place low demands
on installation and maintenance.
Numerous accessories are available for individual convector types.
MINIB products have won a number of national and foreign awards.

1. UNIT DESCRIPTION
These are wall mounted unit types NU1, NU2, NW 170, NW340, NP1, NP2 (based on the natural convection principle) and NK1, NK2, which are
equipped with fans. Since the units fully use the laws of physics in the area of thermodynamics, they represent the most effi cient means of
interior heating.
BENEFITS OF WALL MOUNTED CONVECTORS:
high output,
silent operation and very low noise of fan units,
light weight compared to other heating units with similar output using the radiation principle,
low hot water consumption,
short response time,
design,
minimal operation and maintenance requirements,
the small installation space is a great advantage of these units. You will appreciate this, particularly in situations when the units are used
during interior reconstruction and for the replacement of old heating units, even in places where suffi cient heating output needs to be maintained.

4. BEFORE INSTALLATION
Use the catalogue to choose a suitable convector - see paragraph 4.1.
Select correct convector position and placement - see paragraph 4.2.
4.1 Suitable Convector Type
Decide whether the convector will act as the main source of heat, an
additional heating element or a thermal barrier.
As the main source of heat in your apartment / room, the convector
should suffi ciently cover the entire thermal loss of the room. Therefore, choose a heating unit with a capacity that is higher than the
thermal loss of your apartment, room, or other premises.
All wall mounted convectors are intended for a dry environment. This
means an environment where the average annual humidity does not
exceed 85%. In terms of convector selection, a dry environment is
generally any environment where no precipitation of vapor occurs in
the convector unit.
4.2 Convector Position
A MINIB Wall mounted convector is intended for installation on walls
under windows or window sills. Install the convector approximately 100 mm under the window frame. Observe the rule according to
which the gap between the fl oor should be greater than 80 mm. Never
cover the top grille - this will result in fl ow reduction and in a considerable decrease of the convector's output.

6. CONNECTION OF FITTINGS
Connect the fi ttings with the supplied standard accessories.
Connect individual inlet and outlet valves. The thermostatic valve
(standard supply) is connected to the water inlet to the convector
for fl ow regulation. The screw fi tting is installed on the outlet pipe.
Sealing must be used in all joints. Flow direction is from bottom to top.
Use the supplied fl exible stainless hoses for exchanger connection
(bellows hose), which will later enable vertical exchanger tilting for
the purpose of cleaning. Connect fi ttings according to Figure 14.
Stainless hoses are designed to withstand a maximum pressure of
1.0 MPa. Hoses must not be stretched, compressed, or otherwise
deformed.
