4.1. Water connections

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

4.1.1 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.
