WALL-MOUNTED CONVECTOR NK1
1. UNIT DESCRIPTION
A wall-mounted NK1 heating unit equipped with fans.
Since the heater fully uses physical laws of thermody-
namics it represents one of the most efficient methods
of interior heating.
Benefits 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 beneficial 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
sufficient heating output is required.

3. TECHNICAL PARAMETERS
Use: dry environment, depending on the specifica-
tion.
Maximum operating pressure: 1 MPa.
Maximum operating temperature: 110 °C.
Operating medium: water. Water may not be mixed
with other substances, such as antifree¬ze fluids!
Environment: interiors with temperatures ranging
between +5 °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 fins through which the heating water flows.
Each position in the table corresponds to Figure No. 1.
Select the correct convector type (with or without
fan) from the catalogue – 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 sufficiently cover the entire
thermal loss of the room. There¬fore, 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 an¬nual 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 ge-neral any envi-
ronment where no precipitation of vapor occurs in the
convector unit.
FIG. 1: COMPONENTS OF THE NK1 CONVECTOR
Design of the heat
exchanger differs
depending on the
convector model.
4. AIR VENT VALVE
– used for venting
(bleeding) the con-
vector.
5. CONVECTOR BODY
– aluminum con-
vector body.
6.
CONVECTOR GRILLE
– a design piece
within the convec-
tor. It must not be
covered!!!
7. PLASTIC COVER –
used for attaching
the grille to the con-
vector body.
8. GRILLE SUPPORT –
for supporting the
convector grille.
13. CONVECTOR SUPPORT PART – a fixing part of the
wall-mounted convec¬tor, supporting part for the
convector body and heat exchanger.
14. RUBBER ANTI-VIBRATION PAD – for flexible
mounting of the fan module.
15. FAN – used for forced convection.
9. ADJUSTING SCREW – used for vertical position-
ing of convector on the wall.
10. CONTROL SCREW FITTING – a valve that controls
/ adjusts the heating water flow.
11. AXIAL RADIATOR VALVE – a valve used for flow
regulation.
12.
THERMOSTATIC HEAD – used for manual regulation.
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 floor should never be less than 110mm (Figure
2). Never cover the upper grille of the convector – this
would result in flow reduction and a considerable de-
crease in the convector output.
