1.0 Installation
1.1 Product description
Lindab’s chilled beam Carat is placed above a perforated suspended ceiling and
supplies cooling, with a low air velocity, to the room below. Carat has a high radiation
quotient of approx. 35% (compared to approx. 5% for traditional finned products).
This gives great freedom in placing, when installing Carat, yet keeps air velocities low.
Carat can be used for cooling. It can be equipped with the Regula Connect conden-
sation guard feature. It offers many possibilities and great flexibility. For example, it is
possible to paint Carat any color you want.
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 “Carat”
• Select “Mounting”
1.4 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.

1.4.1 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.
1.4.2 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.
1.4.3 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.

3.0 Maintenance
The interval of cleaning depends on the indoor environment where the beam is placed.
Under optimal conditions the Carat beams only need cleaning every 5 years.
3.1 Cleaning instructions
– Only use lukewarm water and a mild detergent.
– When cleaning from above, the ceiling plate next to the panel must be removed -
then it will be possible to clean the panel from above.
Handling
NEVER handle the product from the extreme edges or from the pipe tails
ALWAYS handle the product from either the suspension bar, the pipe mani-
fold or the bottom of the ‘A’ profile. Take care not to damage cooling fins or
pipe tails.

4.4 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 should
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 should 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
– There should be used in-line strainers to remove dirt particles from the water.
– If the water contains any additive inhibitor this must be appropriate to use with
copper and solder.
4.5 Capacity test
– Lindabs passive chilled beams are tested according to EN-14518.
