1. Intended Use
Kampmann Katherm NX are built in line with the state of the art and
recognised safety regulations. Nevertheless their use may result in danger
to people or damage to the unit or other material property if they are not
properly installed or properly used.
Katherm NX should only be used indoors (e.g. living space, offices, showrooms
etc.) They are not suitable for use in humid environments, such as swimming
pools or outdoors. The products should be protected from any moisture
during installation. Check the application with the manufacturer in case of any
doubt. Any use other than the use specified above is deemed not to be
correct and proper. The operator of the unit is solely responsible for any
damage resulting from such use. Correct and proper use is deemed to include
observing the installation information described in these instructions.
The installation of this product requires specialist knowledge of heating,
cooling, ventilation and electrical engineering. This knowledge, generally
learned in vocational training in the fields mentioned in section 2, is not
described separately. Errors with the connection or modifications may lead
to the unit being damaged! The manufacturer shall not be liable for any
damage caused by an incorrect connection and/or improper handling.

2. Safety Information
Installation, assembly and maintenance work on electrical units should
only be performed by a qualified electrician in compliance with the VDE
guidelines. Wiring should comply with the applicable VDE regulations and
provisions laid down by the regional electricity providers. Non-compliance
with the regulations and operating instructions may result in the units
malfunctioning with consequential damage and danger to people. The
units may be incorrectly wired by the wires being swapped – danger
of fatal injury! Disconnect all parts of the system from the mains power
supply and prevent them from being reconnected before starting any
connection and maintenance work! The unit should only be connected to
fixed cabling.
Please read these instructions in full to guarantee a correct installation.
Please note the following safety-relevant information:
• Disconnect all parts of the system that are being worked on.
• Ensure that the system cannot be accidentally re-connected!
• Caution! Pipes, casings and fittings may become very hot depending on
the operating mode!
• Qualified personnel must have undergone training to provide them with
adequate knowledge of the following:
• Safety and accident prevention regulations
• Guidelines and recognised technical regulations, i.e. VDE (Association of
German Electricians) regulations
• DIN and EN standards
• Accident prevention regulations VBG, VBG4, VBG9a
• DIN VDE 0100, DIN VDE 0105
• EN 60730 (Part 1)
• Technical wiring regulations issued by the regional electricity providers
Modifications to the unit
Do not undertake any modifications, refurbishments or upgrades on the
Katherm NX unit without discussing these with the manufacturer as these
may impair the safety and operation of the unit. Do not carry out any
action on the unit that is not described in these instructions. On-site
systems and cabling must be suitable for connection to the intended
system!
The floor duct has openings provided for the installation of
a potential compensation line.
3. Models/Scope of Delivery
Floor ducts are delivered as standard with the following (see Fig. 2):
leight-adjustment feet, room-side, 1Rubber underlays for sound
absorption 2; screws and rawlplugs, provided on-site;
lraised floor mounting feet with sound absorption 3

4. Levelling/Water Connection
lRemove the outer stretch wrapping and cardboard box.
Caution: Do not remove the struts during installation and operation.
lPlace the Katherm NX with the PowerKon heat exchanger near the
window.
Caution: The height-adjustment feet are already fitted to the floor duct.
owever, these were attached to the foot underneath the duct
for transportation purposes. Loosen the outer fastening nut on
the height-adjustment feet and turn the raised floor mounting
feet 180° so that is pointing outwards (see Fig. 1) in order to
install and adjust the height of the duct.
lThen set up the floor duct and adjust the height of the height-
adjustment feet 1and adjusting screws on the raised floor mounting
feet with sound absorption 3.
lFix the height-adjustment feet, room-side 1with rubber underlays for
sound absorption 2, with screws and rawlplugs provided on-site.
lUse the pipe opening cut out on the room-side for the water-side
connection. Remove the pipe conduit that has been cut out. Seal
the thermostatic valve and return shut-off valve with appropriate
sealing compound and screw the valves to the fan connections on the
convector.
lThen fit the flow and return pipes.
lRun a pressure test.
lAttach these installation instructions to the floor duct so that they are
clearly visible to any trades people at a later date.
lCover the grille and floor duct with a transparent protective cover to
protect them from dirt or cement.
5. Thermoelectric Actuator
Lay an empty conduit Ø 23 mm for the connection cable from the
thermoelectric actuator to the floor duct and flush-mounted box
(provided on-site) to connect the thermoelectric actuator.

6. Screed Work
Check the following before starting the screed work:
lThe water is connected properly,
lThe electricity is connected properly,
lThe floor duct is the correct height and distance from the window,
lThe grille is covered (Caution! Cement destroys the surface of the grille!),
lThe sound insulation (not with raised floors) is installed beneath the floor
duct,
lThere are no sound bridges to the bare concrete, particularly around the
height-adjustment feet.
lAll openings and cut-outs in the floor duct heating are sealed from the
screed using appropriate material.
lThe duct openings and cut-outs should be additionally sealed when using
floating screed or other viscous floor coverings.
Caution: The floor duct must not be pressed together by the screed or floor.
Provide expansion joints if needed.
7. Dimensions/Height Adjustment
Separately packaged roll-up grilles, e.g.
when using installation covers to protect
from dirt, are pre-rolled in the factory.
If the steel spiral springs are stretched,
this may result in the grille appearing
over-long. Unroll and lay out the grille for
a few hours to return it to its original
length. The frame is easier to fit if the
roll-up grille is inserted with an up and
down movement as per the figure
above.

10. Maintenance
Information
Maintenance on Katherm NX floor ducts should only be carried out
by qualified personnel trained in compliance with the installation and
operating instructions as well as any regulations currently in force. Regular
maintenance and inspections are required in order to permanently
guarantee the function and performance of the Katherm NX.
Heat exchanger
lInspect the integral heat exchanger every six months for dirt and
possible damage. A visual inspection is sufficient here.
lCarefully vacuum the heat exchanger if dirty.
Valves
lInspect the valves as well every 12 months and check the leak-tightness
(visual inspection)!

Sample controls
An option for electric controls is the combination of a room thermostat and the
corresponding number of actuators and valves. The required room temperature is set
on the room thermostat. If the room temperature falls below this set value, the
thermoelectric actuator opens the water-side valve.
