2 Control of delivery
2.1 Before you start
Read through the entire installation instruction before
commencing installation in order to determine which
parts that needs to be performed and in what order to
be done.
Lindab is a supplier of complete water products, but we
offer also a wide range of accesso ries which suit per fectly
to our water products simplifying your installation work,
e.g. different type of hangers, Tektite-couplings, closing
valves, thermostatic valves and actuators, flexible
hoses, customized regulation components, customized
cabeling and more. See also the separate document
“Accessories”.
Lindab will also provide you with a full ventilation system,
with a wide range of Lindab Safe components. See also
“Air Duct Systems”.
2.2 Safe operation
Beware of sharp edges, especially of the coils. Always
wear thin gloves and protective clothing.
All existing safety regulations must be observed
when working with Lindab water products. Check the
weights of the beams or the panels with the installation
instruction before carrying.
2.3 Receipt of goods
Start by checking that the delivery is complete
according to the order and that everything listed on the
consignment note has been delivered. Then carry out a
review of the products and make sure that nothing was
damaged during transportation. If you discover damage
that has occurred during delivery, it must be notified
immediately.
Lindab is not responsible for costs associated with the
replacement of products that have been installed in any
way other than shown in these installation instructions.
2.4 Unloading of goods
The beams and panels are normally delivered packed
on wooden pallets. Lift the pallets carefully with a fork
lift and place them on a dry and plain surface/ground. If
the beams are delivered in single boxes, wooden blocks
should be placed on the ground at one-metre intervals
(or a pallet), before the boxes are been placed to store.
Lindabs water products must be stored on a plane
surface in a dry and well ventilated place, preferably
indoors. If they have to be stored outdoors, protect them
with a waterproof cover and store them protected from
rain beneath a roof or other until they are fitted.
2.5 Handling / Carrying
The beam or panel must be handled with care,
ensuring that it will not be scratched or bended during
transportation, preparation and installation.
Always carry the beams or panels piecewise into the
building. Keep the product in the package as long as
you can.
10-25
kg !
Never use piping connections or edges to lift them,
neither when you unpack them nor when you carry them
towards the construction site.
Do not place the product directly on the floor. Use the
protective corners from package or other clean means
from package to place the product before installation.
Be careful if you must carry a long panel horizontally;
if the panels are bended lengthwise, the profiles may
be deformed and the piping could be loosen from the
panel. When opening the box with a knife, be careful not
to damage the product.
Each beam is equipped with protective film to avoid any
damage during transportation and handling on building
site. The film needs to be removed before commissioning
the products.

Max. working pressure 10 bar
Max. recommended dynamic pressure 0.2 bar
Max. test pressure 16 bar
3.7 Water quality
Lindab recommend water treatment and quality to be
according to VDI 2035-2.
• The water preparation and maintenance for the chilled
beam water circuit must be handled by a specialist.
• To prevent corrosion, the water circuit must be
airtight.
• The water system must also be equipped with
aerators to remove any build-up air in the system.
• The water must be oxygen free, to prevent corrosion.
• The water system must be filled with potable water
that complies with the “EC directive 98/83/EC”.
• pH value of water must be between approximately
6-9 pH.
• The water velocities should not exceed 1m/s, and
should be kept as close to the nominal flow as
possible to minimize noise and optimize the energy
yield.
• Use in-line strainers to remove dirt particles from the
water.
• If the water contains any additive inhibitor, then it
must be appropriate to use with copper and solder.
3.8 Air quality
Primary supply air have to be clean, dry and filtered
before reaching the beam.

3.9 Capacity test
Lindabs active chilled beams are Eurovent-certified and
tested according to EN-15116.
Please visit Plexus on www.lindqst.com and see
Eurovent for more details.

Installation instructions Plexus
4 Connections
4.1. Water connections
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. Please note the flow direction indicator on the valve to insure correct installation in relation
to the desired flow.
When connecting a panel or a beam with the piping system either a push-on fitting or a compression coupling should
be used. Lindab have tested and recommends push-on fittings from Tectite (which are available as accessory. See
Accessories.
To avoid sound being transported over the beam, we recommend to use flexible hoses between the piping and the beam
connections.
4.1.1 Before installation
• Notice! The connection pipes are internally soft-welded, therefore it’s not allowed to solder the beam to the pipes. For
other than Lindab fittings and valves, please consult the installation guide for the specific fitting for further details on
proper installation.
• Both inlet- and return pipes are covered by a plastic or rubber protection cover, which must be removed before
installation.
• After removing the protection cover, make sure that the pipe is intact and undamaged, especially at the pipe end, as
even small dents and scratches potentially pose a risk of leakage in the system.
• Eventually deburr the pipe ends on the inside and the outside, using a deburring tool before installation.
• Always remember to do a pressure test after assembly the pipe work.

lindab | we simplify construction
Installation instructions Plexus
4.1.2 Push-on fitting
• Mount a push-on fitting to the pipe. Make sure to press the fitting all the way onto the pipe. Cooper inserts aren’t
required !
Picture 8.b
Push-on fitting on
• Mount a push-on valve to the pipe. Make sure the valve has the correct flow direction (see indication arrow on the valve)
and that you have the correct valve, when integrated valve has been chosen (see indication on valve or follow cabelling
to Regula Connect card). Cooper inserts aren’t required !
4.1.3 Compression fitting
• 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 will not be crushed when mounting the compression fitting, a copper insert must be
inserted into the pipe (always part of the delivery).
• 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.

4.1.5 Additional Lindab accessories for water
connections
Valves and fittings
Lindab TTR and TTV water valves
The Lindab TTR and TTV valves must be used with all
standard application chilled beams, radiant panels and
facade units. The TTR
and TTV valves ensures
easy and fast installation
thanks to the simple yet
effective Tectite push-on
connections.
For further information, please see TTR/TTV water
valves documentation.
Ballorex Dynamic
For application in systems where pressure alterations
may occur, the Ballorex Dynamic ensures an easy and
precise dynamic flow regulation.
Further information on request.
Push on valve with air vent
(aerator)
If a waterborne unit is mounted
in a location where issues with
build up air may occur, appling
an aerator is recommendable.
As our aerators comes coplete
with Tectite fittings, installation is done in mere seconds.
Order no: 647690 (12mm)
Ballofix valves
For easy closing off water connection pipes (available with or
without handle).
Order no: 642663 / 642662
(without handle, 12mm)
Valves and Actuators installation
When actuator and valves are ordered together with
the Plexus and other Regula components, the cables
are pre-connected to the Connect card / Secura
from factory - (depending on your chosen solution).
The actuator and valve is taped to the side of the Plexus
and has to be connected to the correct water-pipe, turning the right way.
Example
Push on valve with Actuator installed on the battery’s
cold water outlet.
Valve arrow indicator must point in same direction as
arrow on beam pipe label.
Actuators
The actuator is a thermoelectric
actuator for opening and closing
valves on heating circuit distributors of concealed floor heating
and cooling systems. Features, as
protection in case of leaky valves,
compact and modern casing, versions in normally closed and normally open, valve adapter concept
and an enhanced life time makes
the actuator competitive and flexible. The actuator is
controlled by a room thermostat with two-point output or
pulse-width modulation.

4.2 Air connections
4.2.1 Air connection installation
The primary air supply must be connected with instructions from a ventilation specialist. Lindab’s chilled beams
can beneficially be used together with Lindab’s Safe®
duct systems.
We recommend a flexible duct connection, like Lindab
DRATMFU-125, to balance out different installation
heights or directions between connection and duct and
avoid sound will be diverted from piping system to the
ceiling.

6.2 Adjustment of air distribution profile
Plexus comes as standard (S) with fixed angled JetCone Nozzles, which provide 360˚ optimal air distribution.
6.3 Measuring air pressure and calculating the air flow
Before calculating the airflow, the static nozzle pressure must first be measured. The static nozzle pressure is the air
pressure available at the nozzles.
6.3.1 Measuring static nozzle pressure and air pressure
• To measure the air pressure, a manometer, ( analogue or digital ) will be needed. Lindab recommends PC410.
• Insert the measuring tube onto the specialized measuring nozzle.
• Read of the static nozzle pressure from the manometer (PC410).
P
stat
Room
Lindab PC410
Order no: 103344
6.3.2 Calculating the actual air flow
• After measuring the static pressure, read the settings of the four JetCone adjustment pins to find the mean value of
the pins.
• Locate the diagram inside the openable perforated faceplate, (also see next page), and use the static nozzle pressure
and the mean value of the pins to find the current airflow.
6.3.3 Changing the actual air flow
• Measure the static nozzle pressure.
• Locate the air pressure/airflow diagram inside the openable perforated faceplate. (Also see diagrams on next page).
• Find the mean value of the 4 pins to reach the desired airflow, in the diagram. Use the static nozzle pressure and the
desired airflow to find the mean value of the 4 pins.
• Adjust the 4 pins in the Plexus, so the mean value of the pins will correspond with the mean value found in the
diagram.
• See example in 6.1.3 , asymmetric pin setting: 2 + 3 + 5 + 6 = 16/4 = 4 . ( Where (4) was the value read in diagram).
6.3.4 Changing the air distribution profile

6.4 Water flow rate
6.4.1 Pre-setting of valves
For the presetting of valves, please see the TTR/TTV water valves documentation.
6.4.2 Balancing strategy
Lindab recommends always balancing the water system to guarantee thermal comfort in all areas, to avoid noise nuisance
problems and to safe energy. A hydraulic balance is obvious to ensure that all the beams (panels or facade units) in the
system will be always supplied with their required (planned) water flow rates (calculated with “Water Calculator on www.
lindQST.com).
Lindab refers to the proportional method, where all beams (panels or facade units) are balanced to the same
proportion of the requested water flow rate (for example Broen, www.ballorex.com)

7. Maintenance
The interval of cleaning depends on the indoor environment where the beam is placed. Under optimal conditions the
beams only need cleaning every 5 years.
• Open the inlet plate using no tools (7.2)
• Clean the battery downside and the inlet faceplate inner parts with a dust cleaner / vacuum cleaner.
• Only use lukewarm water and a mild detergent and a piece of wet cloth to clean the inlet face plate.
• Open the inspection hatch (7.3)
• Clean the air plenum chamber and air connection with a vacuum cleaner
• Lower battery if water pipe connections are connected to system by flexhoses. ( Otherwise this is not possible,
See7.4)
• Clean the top side of the battery, nozzle plate, JetCones and the mixing chamber with a dust cleaner / vacuum
cleaner.
7.1 Remove the outlet front grille

At Lindab, good thinking is a philosophy that guides
us in everything we do. We have made it our mis-
sion to create a healthy indoor climate – and to
simplify the construction of sustainable buildings.
We do that by designing innovative products and
solutions that are easy to use, as well as offering ef-
ficient availability and logistics. We are also working
on ways to reduce our impact on our environment
and climate. We do that by developing methods to
produce our solutions using a minimum of energy
and natural resources, and by reducing negative ef-
fects on the environment. We use steel in our prod-
ucts. It’s one of few materials that can be recycled
an infinite number of times without losing any of its
properties. That means less carbon emissions in na-
ture and less energy wasted.
