INSTALLATION GUIDE – WALL-MOUNTED CONVECTOR NK2
1. UNIT DESCRIPTION
A wall-mounted NK2 heating unit equipped with fans.
Since the heater fully uses physical laws of thermody-
namics it represents one of the most effi cient methods
of interior heating.
Benefi ts of heating convectors:
High output
Silent operation or low noise for units with fan
Lightweight compared to heating units with similar
output which use radiation principle
Low hot water consumption
Short response time
Design
Minimum requirements for operation and mainte-
nance
A great advantage of these convectors is the small
required installation space. This is benefi cial par-
ticularly in a situation where the heating units are
used in interior renovation and replacement of old
heaters with new ones and in situations where
suffi cient heating output is required.

3. TECHNICAL PARAMETERS
Use: dry environment, according to the specifi cation.
Maximum operating pressure: 1 MPa.
Maximum operating temperature: 110 °C.
Operating medium: water. Water may not be mixed
with other substances, such as antifreeze fl uids!
Environment: interiors with temperatures ranging
b5 °C and +40 °C.
1. EB CONTROL UNIT – fan motor control unit.
2. CABLE GROMMET – intended for cable installation
to the control unit.
3. HEAT EXCHANGER – copper pipes with pressed-
on aluminum fi ns through which the heating water
fl ows.
Each position in the table corresponds to Figure No. 1.
Select the correct convector type from the cata-
logue – see paragraph 4.1.
Select the correct convector position and location
– see paragraph 4.2.
4.1 Suitable Convector Type
Decide whether the convector will act as the main
source of heat, or an additional heating element or, as
the case may be, as a heat 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, always
choose a heating unit with a capacity that is higher
than the thermal loss of your apartment, room, or
other areas.
All wall-mounted convectors are designed for dry
environment. A dry environment is an environment
where the average annual relative humidity does
not exceed 75%. A wet environment is an environ-
ment where such average annual value is equal to or
greater than 75% or where the convector is exposed
to direct contact with water. In terms of convector
selection, a dry environment is in general any envi-
ronment where no precipitation of vapor occurs in the
convector unit.

COMPONENTS AND DESCRIPTION
OF THE PARTS OF THE CONVECTOR
Design of the heat exchanger
differs depending on the con-
vector model.
4. AIR VENT VALVE – used for
venting (bleeding) the convec-
tor.
5. CONVECTOR BODY – aluminum
convector body.
6. CONVECTOR GRILLE – a design
piece within the convector. It
must not be covered!!!
7. PLASTIC COVER – used for
attaching the grille to the con-
vector body.
8. GRILLE SUPPORTING MEM-
BER – for supporting the con-
vector grille.
9. ADJUSTING SCREW – used for
vertical positioning of convec-
tor on the wall.
10. CONTROL SCREW FITTING –
a valve that controls / adjusts
the heating water fl ow.
11. AXIAL RADIATOR VALVE –
a valve used for fl ow regulation.
12. THERMOSTATIC HEAD – used
for manual regulation.
14. RUBBER ANTI-VIBRATION PAD – for fl exible
mounting of the fan module.
15. FAN – used for forced convection.
13. CONVECTOR SUPPORT MEMBER – a fi xing part of
the wall-mounted convector, supporting part for
the convector body and heat exchanger.
4.2 Convector Position
Wall-mounted convectors MINIB are intended for in-
stallation on the wall below window frames or sills.
Make sure to follow the principle that the distance
from the fl oor should never be less than 110 mm (Fig-
ure 2). Never cover the upper grille of the convector -
this would result in fl ow reduction and a considerable
decrease in the convector output.
