Directly after the Groove Tube silicone installation
(before it cures), walk tubing off a decoiler into the
Climate Panel groove.

Step 8:
After Climate Panels and U-turn strips are installed,
vacuum groove out thoroughly just prior to
installing tubing.
If trapped in the groove, any debris, screws, nails,
etc, will damage the tubing and keep it from lying
flush with the top surface. When penetrating the
floor, use a plastic elbow sleeve:
1. Figure the leader length of the supply line to
the manifold area.
2. Feed leader length through plastic elbow
sleeve. (Be careful not to scratch the tubing
in the process.)
NOTE: Feed the tubing through an unsecured
plastic elbow sleeve.
3. Feed the leader length through the floor.
4. Secure the fastener clip to the floor.
Directly before installing tubing into the Climate
Panels, run a

" to ¼" bead of Viega’s Groove
Tube silicone into the panel grooves.
• Guaranteed not to damage PEX tubing
or aluminum, the Groove Tube is strongly
recommended.
• Do not use anything but 100% silicone rated
for 180°F.
• Do not use caulking or any other type of
sealant or adhesive.
Installers: Since silicone becomes tacky
in 8 to 10 minutes, it is recommended that
silicone is applied only to a section that
can be covered in this amount of time.
• Do not let silicone set up before tubing is
inserted.
NOTE: It is imperative to make sure tubing is com-
pletely in its tracks before silicone hardens. Tubing
may have to be hammered in using a rubber mallet
or a pneumatic soft-tipped palm hammer.
Run supply tubing from manifold supply valves into
high heat loss areas first (e.g. closest to exterior
walls, windows, sliders, etc,) and then into the interi-
or of the room.
This will provide more Btu output where it is needed
due to higher water temperatures. Continue the cir-
cuits, laying them out in the same direction toward
the interior of the room.
