System Fluid
For radiant installations, use one of the following
two fluid options.
• Water
• Propylene-glycol/water mix, not to exceed
50% glycol, by volume
DO NOT use methanol or ethylene glycol.
These fluids may damage the Radiant
Ready 30E components.
Required Tools
• One (1) PEX Tube Cutter (E6081125 or E6081128)
• One (1) Service Wrench (E6111188) or
crescent wrench
• One (1) fitting tool (depending on tubing/
fitting style)

MLC Press Fitting Tool
Connecting Tubing to the Manifold
Important! All Canadian and some U.S.
jurisdictions require a hard-plumb port.
See the Hard-plumb Port instructions in
Section 11: Customization Options
for further details.
General Tips
When connecting the tubing to the manifold, it is
a good idea to follow these general rules to ease
the installation process.
• Work with only one loop at a time. Start with the
connection on the return manifold and end with the
supply connection. The return manifold is located
above the supply manifold in the standard unit.
• Making a connection between two existing
connections can be difficult, so work from left
to right on the manifold to allow free space to
properly make the connection.
Refer to the following steps to properly connect the
tubing to the manifold.
1. Determine the fitting style and attach the fittings to
the manifold or tubing (depending on fitting style).
a. For ProPEX and MLC Press: Attach the fitting to
the manifold, tighten down (paying attention not
to damage the O-ring) and make the connection
to the tubing.
b. For QS20 and MLC compression: Attach the
fitting to the end of the tubing first, then connect
to the manifold and tighten to create the seal.
2. Determine the supply and return end of the first
loop of tubing.
3. Estimate where the end of the return tubing will
need to be to make the connection, leaving several
extra inches out past where the connection will be
made and cut the tubing at this location.
DO NOT cut the pipe short, as it may
become very difficult to make a connection
to the manifold if the tubing does not reach
the manifold.
4. Position the tubing in preparation for the final
connection. At this time, it may be necessary to
trim the tubing length to make the connection.
5. Make the tubing connection.
a. Pay attention not to damage either the O-ring
on the R20 connection, the barb on the ProPEX
connection or the sleeve of the MLC connection.
b. For ProPEX, place ProPEX Ring on end of tubing,
expand the tubing and place onto ProPEX
connection.
c. For MLC Press, chamfer end of tubing, insert
tubing into MLC connection and crimp with the
Crimp Tool.
d. For QS, place nut, compression ring and insert
onto the tubing, connect to the manifold and
tighten down.
e. For MLC Compression; chamfer end of tubing,
place nut, compression ring and insert onto
the tubing, connect to the manifold and
tighten down.
6. Repeat Steps 4 and 5 for the supply end
of the tubing.
7. Repeat Steps 3 through 5 for each
additional loop.
8. Cap any unused manifold outlets with a Manifold
Loop End Cap (A2080020) (purchased separately).
Each loop requires two (2) caps. Capping the outlet
minimizes the chances of accidentally opening the
valve and causing fluid to leak from the system.
