Installing Uponor
AquaPEX Tubing in
Frame Construction
Tubing Runs
• Leave extra tubing at the beginning
and end of runs to simplify the
connection to fittings, multi-ports
and manifolds.
• Ensure runs are as direct as possible
between fittings, multi-ports or
manifolds and the fixtures they supply.
• Insulate hot- and cold- water
tubing runs where code requires
or as necessary.
• For information about locations and
techniques for drilling though load-
bearing construction, consult your local
building codes.
• In residential or non-return plenum
applications, you may bundle cold
water tubing runs together and/or
hot water tubing runs together with
a suitable plastic material, unless
prohibited by local code. Best practices
do not recommend the bundling of
hot-water tubing runs and cold-water
tubing runs together.
Caution: When installing
in attics, install the tubing
below the insulation. Note the
location of fittings in the attic
space for inspection purposes
during pressure testing.
Recessed Lighting
When installing Uponor AquaPEX tubing
near recessed light fixtures, Uponor
recommends the tubing be a minimum
of 12" away from a non I.C.-rated light
fixture. When it is necessary to install
closer than 12" away from a non I.C.-rated
light fixture, follow these guidelines:
• If there is not enough room in
the joist cavity to meet the 12"
restriction, insulation around the
tubing is required.
• Use only insulation rated to withstand
the temperature generated by the
fixture.
• Insulate all tubing that is within 12"
of the recessed light with closed-cell
polyethylene, polyolefin or other
suitable pipe insulation for a distance
of 12" on either side of the light
fixture.
• Insulation is required anytime a UV light
source is used (including fluorescent
bulbs); you must protect tubing from
direct and indirect UV exposure.
Note: There are two types of recessed
lights: Type I.C. (Insulation Contact),
which allows direct contact with
thermal insulation, and Type Non-
I.C. (Non-insulation Contact), that
requires a 3" minimal clearance from
thermal insulation.
