INSTALLATION GUIDE – WALL-MOUNTED CONVECTORS
1. UNIT DESCRIPTION
A wall-mounted heating unit. Models NUF1, NUF2, NMF1,
NWF1, NWF2, NPF1, and NPF2 use the natural convection
heating principle, models NKF1 and NKF2 are equipped
with a fan for forced convection. Since the heater uses
physical laws of thermodynamics 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 suf-
fi cient heating output is required.
3. TECHNICAL PARAMETERS
Use: Convectors without fan are designed for dry
and wet environment, and convectors with a fan
are designed for dry environment only.
Maximum operating pressure: 1 MPa.
Maximum operating temperature: 110 °C.
Operating medium: Water. It is not allowed to use a
medium other than 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. CONVECTOR BODY – Aluminum convector frame
painted with color shade according to the catalog.
2. HEAT EXCHANGER – Copper pipes with pressed-
-on aluminum fi ns through which the heating water
fl ows. The heat exchanger design differs according
to the convector model.
3. COVERING GRILLE – Grille used to cover the convec-
tor outlet; with color shade according to the catalog.
4. AXIAL FAN (models with a fan) – Set of fan modules
for forced convection of the heated air. The number
differs according to the length of the convector.
5. EB CONTROL UNIT (models with a fan) – Fan motor
control unit.
6. EB CONTROL UNIT BRACKET (models with a fan)
– Used for fi tting the control unit on the convector
casing.
7. TEMPERATURE SENSOR (models with a fan) – Used
for sensing temperature for the EB control unit.
8. THERMOSTATIC HEAD – Used for temperature con-
trol and operation of the axial valve.
9. AXIAL THERMOSTATIC VALVE – A valve used for
incoming heating water fl ow control.
10. CONTROL SCREW FITTING – A valve which cont-
rols/adjusts the heating water fl ow.
11. GASKET RING – A gasket in the connection be-
tween the valve and the heat exchanger.
12. WALL SCREW – A screw used to attach the convec-
tor to the wall.
13. SCREW ANCHOR – For attaching the convector to
the wall.
