1.0 Installation
1.1 Product description
The Plafond chilled beams are designed for installation in the space between the ceil-
ing and the wall. Especially suitable when the ceiling should be free from equipment.
The supply air is directed along the ceiling or wall.
1.2 Handling
The beam must be handled with care, ensuring that the beam does not sustain dents,
scratches or bends during installation.
Always seek to lift the beam at multiple points.
– Do not lift in pipes
– Do not lift in edges
– Each beam is equipped with protective film to avoid any damage during transport
and handling at building site. The film needs to be removed before commissioning
the products.
1.3 Mounting instruction
– Please visit www.lindqst.com
• Select Documentation Finder
• Select “Plafond”
• Select “Mounting”
1.4 Air connection installation
The primary air supply should be connected with instructions from a ventilation spe-
cialist. Lindab’s chilled beams can beneficially be used together with Lindab’s Safe®
duct systems.
1.5 Connection description water
Flow indication arrows are shown on the inlet and return pipes in order to assist the
installer. If the beam has been ordered with integrated valves, a special direction
of the flow must be upheld to ensure correct flow through the thermostatic valve. If
the beam has been delivered without integrated valves, the flow can be reversed,
depending on the location of the retrofitted valve. Please note the flow direction indi-
cator on the valve to insure correct installation in relation to the desired flow.

1.5.1 Push-on fittings
– Please ensure that all pipes and fittings are undamaged, as even small dents and
scratches potentially pose a risk of leakage in the system. Always remember to do
a pressure test after assembly of the pipe work.
– Both flow and return pipe is covered by a plastic or rubber protection cover,
which should be removed before installation.
After removing the protection cover, make sure that the pipe is intact and undam-
aged, especially at the pipe end. Crocked or in other ways imperfect pipe ends will
result in leaks. Deburr the pipe on the inside and the outside, using a deburring tool
before installation
– Mount a push-on fitting to the pipe. Make sure to press the fitting all the way onto
the pipe. Consult the installation guide for the specific fitting for further details on
proper installation.

Push-on valve
Notice! The connection pipes are internally soft-welded why it’s not allowed to
solder the beam to the pipes.
1.5.2 Compression fitting
– Please ensure that all pipes and fittings are undamaged, as even small dents and
scratches potentially pose a risk of leakage in the system. Always remember to do
a pressure test after assembly of the pipe work.
– While mounting a compression fitting, the pipe will be exposed to a big amount
of force, creating a risk of crushing the pipe. To ensure that the pipe won’t be
crushed when mounting the compression fitting, a copper insert should be
inserted into the pipe.
– Both flow and return pipe is covered by a plastic or rubber protection cover
during transport, which must be removed before installation.
– After removing the protection cover, make sure that the pipe is intact and undam-
aged, especially at the pipe end. Crocked or in other ways imperfect pipe ends
will result in leaks. Deburr the pipe on the inside and the outside, using a deburr-
ing tool before installation

– The copper insert should be placed inside the pipe on the beam. Always support
the copper pipe coil when inserting the copper insert into position.
– Mount a compression coupling and/or a valve to the pipe. Don’t stress the nut too
much, since this may crush the pipe.
Notice! The connection pipes are internally soft-welded why it’s not allowed to solder
the beam to the pipes.
1.5.3 Flex hoses
Our flexible hoses can be used with both compression and Tectite fitting. We recom-
mend using Tectite fittings, for easier and faster mounting.
– Please ensure that all pipes and fittings are undamaged, as even small dents and
scratches potentially pose a risk of leakage in the system. Always remember to do
a pressure test after assembly of the pipe work.
– Both flow and return pipe is covered by a plastic or rubber protection cover,
which should be removed before installation.

that the flexible hose is pushed fully into the fitting. Consult the installation guide
for the specific fitting for further details on proper installation.

2.0 Commissioning
2.1 Product labeling
Fig.1: Label location exterior (On plastic wrapping)
Fig.2: Label location interior (Air connection end)
On the label you’ll find:
– Order: Order identification number.
– Pos: Order position.
– Product: Product configuration.
– Project: Project name.
– Mark: Marking noted on order.
– Nozzles: Number of nozzles.
– Plugs: Number of plugged nozzles.
– Product ID: Product number.
– Sign: To be signed when checked and commissioned on site.
2.2 Measure air pressure and calculating the airflow.
Before calculating the airflow, the static nozzle pressure must first be measured. The
static nozzle pressure is the air pressure available at the nozzles.
2.2.1 Measure the static nozzle pressure.
– To measure the air pressure, a manometer, analog or digital (such as the Lindab
PC410) will be needed.
– Insert the measuring tube onto the specialized measuring nozzle
– Read off the static nozzle pressure from the manometer

2.2.2 Calculating the airflow
– After measuring the static nozzle pressure, calculate the air flow per nozzle:
q=0.0209 ∙ √P
q = air flow per nozzle
P = static nozzle pressure
– After finding the air flow per nozzle, find the needed number of open nozzles:
q tot/q=n open
q tot = total air flow
n open = open nozzles
– Alternatively, read off the needed number of nozzles in the diagram below.
Diagram 1: Shows needed number of open nuzzles to reach a desired air flow at a
given pressure.

2.3 Apply plugs to reduce airflow
– When the needed amount of open nozzles have been found, plug or unplug noz-
zles to reach the needed amount.
– Use the specially designed Lindab Nozzle Plugs and Lindab plugging tool to plug
the nozzles.
– To plug a nozzle, first locate the nozzles to plug. Keep in mind that the closed
nozzles should be diveded as equally along the beam as posible to reach a sym-
etric spread pattern.
– Insert the plug into the nozzle. Make sure that the plug is fully inserted.
– The reconfiguration is now complete.
2.3.1 Removing plugs to increase airflow
– Reverse the steps above.

3.0 Maintenance
The interval of cleaning depends on the indoor environment where the beam is placed.
Under optimal conditions the Plafond beams only need cleaning every 5 years.
3.1 Cleaning instructions
– Remove the faceplate
– Clean underneath the battery with a vacuum cleaner and a piece of wet cloth
– Only use lukewarm water and a mild detergent.
