installation, while the SelfTite
clamps need a pair of SqueezeTite
Pliers. See manifold assembly sec-
tion for more details. The number of
Onix coils on the jobsite should cor-
respond to the number listed in the
Zone List report.
3. Manifolds
Only use Watts Radiant manifolds or
manifold components for field-con-
structed manifolds.
4. Unwinder.
A required component for easily
unrolling each precut Onix coil
without kinks and twist.
5. Field Repair Kit.
Each kit will contain two barb-by-
barb splices and four Onix Clamps.
6. Manifold Mounting Bracket.
Each bracket can be used to
temporarily or permanently mount
each manifold pair to the floor or
wall. Use either Watts Radiant
brackets or SnapClips to hold mani-
folds.
7. Watts Radiant staple gun, staples
and NailTites.
8. Pressure test kit.
Each manifold pair must be pressure
tested. This helps ensure each Onix
connection has been performed cor-
rectly and to make sure no damage
has been done to the tubing during
installation.
9. Installation Accessories
a. Electrical Tape for
temporarily mounting the
manifolds or taping ends of
tubing together.
b. Cable Ties, ClipTies,
Screw Clips or other
fasteners.
Since rewire/rebar is commonly used
in concrete slabs for structural integri-
ty, it is a good practice to attach Onix
to the rewire/rebar. This is done with
nylon cable ties or Watts Radiant
ClipTies and Clipper tool. Each will
secure the Onix to the rewire/rebar in
such a way to prevent movement of
the tubing during the concrete pour.
In applications where rewire/rebar is
not used or an insulation board is
placed underneath the slab, some addi-
tional attachment devices can be used
to secure the Onix. RailWays
™
can be
attached to subgrade with the use of
ground stakes or talons. Watts
Radiant s Foam Staples or Foam Clips
can be used to secure the Onix tubing
directly to the insulation board.
