1.0 Installation
1.1 Product description
Lindab’s heating and cooling panels Atrium /Loggia can be mounted almost anywhere
in the ceiling or on the wall and primarily provide heating/cooling by radiation. The
radiation share for the panels exceeds 50% to 60%, compared to approx. 5% for con-
ventional finned products. Since the air velocities can be kept low, this result in a
draught-free environment. Radiant heating can also be used with high ceiling heights
since the radiant heating, despite the high placement, heats the underlying surfaces
directly without any losses to the air.
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 “Atrium” or “Loggia”
• 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 control valves have been ordered separately, a special direction of the flow
must be upheld to ensure correct flow through the control 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 John
Guest push on fittings as well as push-on fittings from Tectite (available as accessory.
See Accessories).
To avoid sound being transported over the beam, we recommend to use our flexible
hoses between the piping and the beam connections. See Accessories.
NB! Every control valve can create sound when it is installed directly connected to the
water in- or outlet (or into the piping in close distance to the in- or outlet of the water
product). To avoid unwanted sound generation we recommend to always use a Lindab
control valve LinFlow-A (angled) or LinFlow-S (straight) and calculate the beam with the
valve in LindQST\waterborne calculator.

1.4.1 Before installation
Notice! The connection pipes are internally soft-welded, therefore it is 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 of the pipe work.

1.4.2 Push-on valve
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 !
Please refer to the suppliers manual.
1.4.3 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 won’t 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.
1.4.4 Flexible hoses
Our flexible hoses with straight ends can be used with both push-on and compres-
sion fitting.
We recommend to use our flexible hoses with push-on fittings, for easier and faster
mounting.
For the connection to an enclosed valve with integrated push on coupling a flexible
hose with straight end (male) or with push on (female) and a short copper pipe can be
used.
Please refer to the suppliers manual.
* Lmin = 70 mm (to ensure you can open the couplings again).
Lindab flexible hoses are available with straight end (male) for direct connection to Lindab valves also.

3.0 Maintenance
The interval of cleaning depends on the indoor environment where the beam is placed.
Under optimal conditions the Atrium 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.

4.3 Pressure Class
The waterborne products in Lindab, active chilled beams (battery products), passive
chilled beams (battery and strips products), facade units (battery) and radiant panels
(strips and panels) are produced according to pressure class PN10 according to EN
1333: 2006.
This means the maximal working pressure for the products at a water temperature of
20°C must not exceed 10 bar.
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.
