Product Highlights
Description
TrueFLOW Manifold without Flow/Temperature Meters come fully assembled ready for installation. The TruFLOW balancing Hex Key is used on the internal balancing valves of the supply manifold to balance the loops across the manifold. Manifold is shipped with the appropriate number of Actuator Adapters (A2630028). Maximum recommended flow to the manifold based on manifold body diameter is 21.0 gpm.
Note: The Flow Meters (A2640015 and A2640027) are purchased separately and installed on the return manifold.
This manifold requires (24) Loop Fitting Assemblies:

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
- A2631250: 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.
- A3010522: Thermal Actuator (4 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.

Q: can each of supply and return be flipped horizontally, so that it connects on the left, instead of the right, as shown?
Asked by anon 12 years ago
Add your answer
Verified Reply- SupplyHouse StaffYes, it can. The manifolds can be removed from the mounting brackets so they can be swapped.
Q: I seem to have a flow problem from 3 of the ports. When I bleed the air from each line the flow was strong from only one of the 4 loops, the other 3 the flow was very poor. I did each line individually so I am not sure what maybe causing the poor flow on 3 of the 4 loops. Any help would be greatly appreciated.

Jim, This sounds obvious, but check to verify you don't have feed and return lines on the same manifold. A simple way to check layout is with a garden hose. Its easy to forget once lines are covered. Vance Sent from my Windows Phone
Water will always take the path of least resistance, are your loop lengths the same? I found any difference in length, ie my loops are 300 feet ea with two of them 304 feet any more than that will cause preferential flow. But is adjustable with the manifold. If you have to you can add length to your loop with pref flow to even it out if necessary Hope this helps. Rayman
Q: Can this system be retrofitted to zone a circa 1900s home with existing radiators? I aquired the manifolds for a different project but did not use them.
Asked by Jerry 14 years ago
Add your answer
Yes but you have to bring each radiator to this manifold seperate> This will give you a chance to balance the radiators because they probably different sizes so one will got hotter sooner then the others. I will recommend you to bring 1/2" pex tubing from each radiator if its possible.
you must run each radiator as a home run to the manifold, a min of 5/8 pex must be used
Are you retrofitting the house with radiant floor heating? Sent from my iPhone
Q: I have some buildup preventing one of the loops in the TruFLOW Manifold from closing and hot water bleeding by that loop when the pump is running providing heat to one of the other loops. Can I disassemble the loop and clean out that valve? I have one ball valve going in the supply loop to the floor above and not a way to shut off the return water line to the Manifold which as the defective valve controlled with the Uponor Thermal Actuator. Can I turn off the water to the supply line and will this prevent the water from leaking out of the manifold when I disassemble the valve?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, you can clean the valve. You'll have to drain the system down in order to remove the valve.
Q: Can i use this upside down. I need to feed it from the top. Is there a gasket between the end cap and 1" conector A4133210?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe manifold can be mounted upside down, but any flow meters would not be able to operate. The A4133210 ProPEX adapter screws either directly into the manifold or into TruFLOW Manifold Supply and Return Ball Valves without any gasket.
You can easily undo the mounting bracket and swap the supply and return halves of the manifold such that the supply is at the top. Without any need to mount it upside down.
Q: can i manually close the idividual port on a two loop manifold
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, you can shut off flow using the included hex key wrench.
Q: How does the air bleeder vent work with this manifold? Does a seperate automatic air vent need to be installed?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou do not need to install a separate automatic air vent, but it would help with the air-bleeding process.
Q: Can I switch the supply and return so the supply is on top?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, you can switch the orientation of the manifold in the brackets.
