Watts Onix Parts list manual

The Watts Radiant Staple Gun is a pneumatic (air-pow-
ered) tool. To operate correctly, the staple gun requires an
air compressor capable of delivering 100 psi. Each tool is
designed and sold only for the purpose of installing Watts
Radiant’s Onix, RadiantPEX, or WaterPEX radiant tubing, and
must not be used for any other purpose.
If you experience more than one or two punctures, then
either the gun or your installation procedures may be faulty.
Please call Watts Radiant for assistance before proceeding.
Watts Radiant recommends replacing radiant tubing that
has been punctured. However, if you choose to repair the
puncture, always use a Watts Radiant repair kit. This kit has
been carefully selected to give you a trouble-free splice joint
if used as directed. Refer to the appropriate Watts Radiant
manuals and guidelines for technical assistance to this pro-
cedure. Watts Radiant cannot warrantee field splices, as the
installation is not under our supervision. This kit has been
carefully selected to give you a trouble-free splice joint if
used as directed.
Note: Please refer to Watts Radiant’s product warranties.
GENERAL CAUTIONS
Do not operate this tool before reading the following
cautions and instructions on the front and back of this
Guideline. Misuse of this tool can cause serious injury or
death. If you are unclear about its proper use, please call
your supplier or call Watts Radiant at 800-276-2419 for
further instructions before using. Return this tool directly to
your supplier if it appears to be in need of repairs.
1. This tool may fire when you first connect or dis-
connect the air hose. Be sure that the tool is unloaded or
pointed in a safe direction before connecting/disconnecting
an air hose to it.
2. Remember that any pneumatic staple gun is exactly
that — a gun. It shoots staples at a velocity sufficient to kill
or permanently injure you or anyone else within range. Never
point this tool at anything except a piece of tubing you want
to permanently fasten down. Never squeeze the trigger when
your finger, hand, or any part of your body is in front of or
close to the firing head.
3. Always wear safety glasses with side shields while
operating this tool. Other workers or visitors to the jobsite
must wear adequate eye protection if they are within range
of the tool. There is always a possibility that a staple may
ricochet off a nail or knot in the subfloor and injure you or
a bystander.
The staples are capable of ricocheting off any wood sur-
face unless the gun is correctly positioned over the tubing.
Do not attempt to staple into knots, even if you must
extend the staple spacing. Never attempt to staple into
concrete, metal, or any nonwooden surface.
4. Use the correct staple gun and quality Watts Radiant
staples to prevent tool jamming and tubing punctures.
Watts Radiant uses a specially-modified Senco gun for
stapling Onix, RadiantPEX, and WaterPEX. Guns are clearly
labeled as are all boxes of Watts Radiant staples. Use of the
non-Watts Radiant staples can cause accidental punctures
during the installation. Please call Watts Radiant or your
distributor, if you are not sure how to proceed.
Occasionally a staple will misfire and puncture the tubing
when the staple clip is down to the last 5 to 10 staples.
Always check to see if the clip is getting low, and insert a new
clip to avoid this potential problem.
5. Before beginning the installation, please refer to
the plans supplied by Watts Radiant or its representatives
with all associated design information. We recommend you
read all appropriate Watts Radiant Installation Manuals and
Guidelines before beginning.

USING THE PEX STAPLE GUN
The PEX staple gun is a Senco staple gun, specially
modified by Watts Radiant both internally and externally for
use with Watts Radiant’s RadiantPEX and WaterPEX. This
staple gun is fitted with a stainless steel guide plate (Order
Number 81005497) that is bolted to the underside of the
gun. It is designed for both 3/8" and 1/2" PEX. If stapling
3/8" PEX, make sure the smaller 3/8" opening is at the
front of the gun. You should see “3/8" PEX” stamped on the
guide plate at the front of the gun. If stapling 1/2" PEX,
unbolt the guide plate and turn it around so the larger 1/2"
opening is at the front of the staple gun. You should see
“1/2" PEX” stamped on the plate at the front of the gun.
When stapling PEX, position the guide plate over the tub-
ing. Make sure the guide plate, at both front and back, is
placed firmly against the plywood. Before pulling the trigger,
make sure that the tail end of the guide plate is also cen-
tered over the PEX. If the tail of the guide plate is not cen-
tered over the tubing, some of the staples may puncture the
PEX. When the guide plate has completely contacted the ply-
wood and is centered over the PEX tubing, pull the trigger
and fire the staple.
PEX Staple Intervals: The PEX staple gun should only
be used for thin-slab applications and not “staple-up” or
“sandwich” applications. For thin-slab applications, staples
should be placed every 12" to 15" along the length of the
tubing. Stapling the PEX at wider intervals can result in the
tubing being too close to the surface of the thin slab. (Watts
Radiant recommends a minimum 3/4" between the top of
the tubing and the surface of the concrete.)
PEX CAUTIONS:
1. Examine each circuit after it has been stapled in
place. The PEX staple gun is designed to leave a 1/8" gap
between the top of the tubing and the staple. This is to make
sure that the tubing is not fractured by the impact of the
staple and to assure that no abrasion is possible between
the staple and the tubing. If the staple is closer than 1/16"
of the tubing, then it should be removed and replaced with a
new staple. Please see the illustration for tolerances.
2. As with any floor heating application, do not install
PEX over floors with asphalt paper “slip joint” in the flooring,
as an unpleasant odor may result. Rosin paper (pink colored)
is generally acceptable.
Note: For best performance, 3 or 4 drops of pneumatic oil
(5-weight, non-detergent machine oil) should be installed once daily
into the air inlet of the staple gun. (More oil drops may be used if
the gun sees continuous heavy service, i.e., more than 3–4 hours
at a time.)
USING THE ONIX STAPLE GUN
The Onix staple gun is a Senco®staple gun, specially
modified by Watts Radiant both internally and externally. The
Onix staple gun is fitted with a stainless steel guide plate
(Order Number 81005498) that is bolted to the underside of
the gun. If stapling 3/8" Onix, make sure the smaller 3/8"
opening is at the front of the gun. You should see “3/8"
Onix” stamped on the guide plate at the front of the gun. If
stapling 1/2" Onix, unbolt the guide plate and turn it around
so the larger 1/2" opening is at the front of the staple gun.
You should see “1/2" Onix” stamped on the guide plate at
the front of the gun.
When stapling Onix, position the guide plate over the Onix.
Make sure the guide plate, at both front and back, is placed
firmly against the surface. Before pulling the trigger, make
sure that the tail end of the guide plate is also centered over
the Onix. If the tail of the guide plate is not centered over the
tubing, some of the staples may puncture the Onix. When the
guide plate has completely contacted the plywood and is cen-
tered over the Onix tubing, pull the trigger and fire the staple.
Onix Staple Intervals: You must use one staple every
6" when the Onix is installed under a wood frame floor. This
ensures good thermal contact between the Onix and the
floor, which is essential for the Onix to deliver its specified
heat output. Spacing the staples too far apart can cause as
much as a 20% loss of peak heat output. For initial Onix
placement, or where there is insufficient clearance for the
gun to be used, we suggest the use of Watts Radiant
NailTites to hold the Onix in place. Although not essential, it
can be very helpful for an assistant to hold the Onix in place
while the installer is stapling. This assistant must wear all
appropriate safety equipment. When stapling Onix on top of a
floor, in preparation for installing an elevated thin slab, you
may increase the staple intervals to 12" or 18". Always
maintain the Onix spacing as indicated on the plans or in
associated design information.
ONIX CAUTIONS
1. Examine each Onix circuit after it has been stapled in
place. If you see that the Onix has been partially compressed
by a staple, you must remove that staple and put in a new
one. The staple can acceptably deform the Onix slightly,
1/16" or less, without causing any difficulties. See the illus-
tration for deformation tolerances when stapling hose.
2. Do not install Onix under floors containing an asphalt
paper “slip joint” between the subfloor and finish floor, as an
unpleasant smell may result. Rosin paper (pink colored) is
generally acceptable.
Note: For best performance, 3 or 4 drops of pneumatic oil
(5-weight, non-detergent machine oil) should be installed once daily
into the air inlet of the staple gun. (More oil drops may be used if
the gun sees continuous heavy service, i.e., more than 3–4 hours
at a time.)
