2.4 Unloading of goods
10-25
kg !
Heavy Load - 2 man job It is recommended to use
a “lift” for mounting.
Hand-pull
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
2 Control of delivery
2.1 Before you start
The beam or panel must be handled with care, ensuring that
it will not be scratched or bended during transportation,
preparation and installation.
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.
Always carry the beams or panels piecewise into the
building. Keep the product in the package as long as you
can.
Lindab is a supplier of complete water products, but we
offer also a wide range of accessories which suit perfectly
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
kg !
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.
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.

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.

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.
Picture 8.a
Push-on fitting of
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).
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.
• Please refer to the suppliers manual.
4.1.4 Flexible hoses
• Our flexible hoses can be used with both push-on and compression fitting. We recommend to use Tectite fittings, for
easier and faster mounting.

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.
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.
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, applying an aerator is
recommendable. As our aerators
comes complete 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)
For more details see: Accessories
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.

4.2.1 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

6.2 Adjustment of air distribution profile
Plexus comes as standard (S) with fixed angled JetCone Nozzles and (L, M, H) with fixed air deflectors, 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).

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
See 6.1.3.

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.

At Lindab, good thinking is a philosophy that guides us in everything we do. We have made it our
mission 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 efficient 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 effects on the environment.
We use steel in our products. 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 nature and less energy
wasted.
