5A. INSTALLATION INSTRUCTIONS
5A.4 Installation of PEX-tubing Start the tubing installation by connecting
the PEX tubing to the manifold. Loops can
be pre-cut if you have figured the correct
leader length (from the manifold to the
actual heated area) when designing the
system with our software. The Radiant
Heating Tubing Requirements Report will
give you the information to cut the loops
from full rolls of tubing with the least
amount of waste.
Install the tubes by unrolling the coil and
stepping the tubes into the tracks in the
panels. Use hard shoes or a wooden piece
on top of the tubes in order to fasten the
tubes in the tracks. Be sure to use a block
when using a hammer or mallet to set the
tubing to avoid denting the aluminum
surface. Follow the loop layout you have
planned and connect the return tube to the
manifold. It is very important that the tubes are snapped down completely into the tracks.
When installing the tubing in the radius panels it is important to pull the tubing tightly around the
bends. This will allow a space for tubing expansion during operation and greatly decrease the
chance of noise during operation. When laying the tubing into the transition pieces we
recommend using a bead of silicone adhesive to secure the tubing because the tubing is loose
in these pieces. We recommend installation of the panel and tubing when ambient
temperatures are above 40°F (4.5°C).
