8-Loop EP Radiant Heat Manifold Assembly w/ Flow Meters

Note: This manifold requires 16 Loop Fitting Assemblies (please see below).

The Engineered Plastic (EP) Heating Manifold Assemblies feature isolation valves and balancing valves with flow meters, and come fully assembled, ready for installation. The manifolds are available in 2- through 8-loop configurations. The body ends feature R32 unions and the loop outlets have R20 male threads. The manifold mounts on a bracket (A2670006) that comes with the assembly.
For cost-effective, durable, hydronic radiant systems, Uponor now offers the Engineered Plastic (EP) Heating Manifold. This new manifold is comprised of thermoplastic, high-performance, advanced materials suitable for use under conditions of high impact, heat and moisture. Successfully installed throughout Europe for the past five years, Uponor now offers this innovative new product in the United States and Canada.
This strong, durable manifold is made of an advanced engineered plastic, which withstands corrosive environments and is unaffected by the rising cost of metal, making it an economical solution for all radiant projects.

  This fitting will connect 5/16" PEX to a loop of the Manifold without requiring the use of a PEX Tool.
• A4020375: 3/8" PEX to R20 Loop Fitting Assembly
  This fitting will connect 3/8" PEX to a loop of the Manifold without requiring the use of a PEX Tool.
• A4020500: 1/2" PEX to R20 Loop Fitting Assembly
  This fitting will connect 1/2" PEX to a loop of the Manifold without requiring the use of a PEX Tool.
• A4020625: 5/8" PEX to R20 Loop Fitting Assembly
  This fitting will connect 5/8" PEX to a loop of the Manifold without requiring the use of a PEX Tool.
ProPEX Loop Fitting Assemblies
• Q4020375: 3/8" ProPEX to R20 Loop Fitting Assembly
  This fitting will connect 3/8" PEX to a loop of the Manifold but requires a ProPEX Expansion Tool to make the connection.
• Q4020500: 1/2" ProPEX to R20 Loop Fitting Assembly
  This fitting will connect 1/2" PEX to a loop of the Manifold but requires a ProPEX Expansion Tool to make the connection.
• Q4020625: 5/8" ProPEX to R20 Loop Fitting Assembly
  This fitting will connect 5/8" PEX to a loop of the Manifold but requires a ProPEX Expansion Tool to make the connection.
• Q4020750: 3/4" ProPEX to R20 Loop Fitting Assembly
  This fitting will connect 3/4" PEX to a loop of the Manifold but requires a ProPEX Expansion Tool to make the connection.

Optional Installation Accessories:

Loop End Cap

• A2080020: Manifold Loop End Cap
  These allow you to cap off a loop of the manifold if it will not be used.

TruFLOW Supply/Return Ball Valves

• A2631252: TruFLOW Supply/Return Ball Valves (box of 2)
  These allow you to quickly shut-off the supply and return sides of the manifold. These valves are R32 thread x R32 thread. The supply and return ends of the manifold is R32.

TruFLOW Supply/Return Adapters

• TruFLOW Supply/Return Adapters
  These allow you to connect the manifold to your supply and return lines. The supply and return end of the manifold is R32 thread. Choose an R32 adapter that will connect the manifold to your desired application.

Actuators

• A3030522: Thermal Actuator (2 Wire)
  If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
