Stainless-steel Manifold Installation Guide Overview Featuring 2 through 8, 10 and 12 loops, the Uponor Stainless-steel Manifold comes fully assembled with flow meters, temperature gauges, ball valves and NPT connections. Note: The valve body with the preassembled flow meters is the supply manifold; the valve body without the flow Thermal Actuator, Two-wire (A3020416) or Thermal Actuator, Four-wire (A3010522) meters is the return manifold.
Mounting Manifold to a Wall 1. Fasten the manifold to a wall using a rigid anchor and mounting screws (included). Mounting Manifold Inside a Wall Cabinet 1. Insert the cage nuts (included) in the mounting rail. 2. Align the manifold bracket holes with the cage nuts in the rail and loosely fasten with bolts (included). 3. Slide the manifold into the desired position and tighten the bolts. Note: For wall cabinet mounting instructions, refer to the Uponor Manifold Wall Cabinet Instruction Sheet.
When using Manifold Elbow or Offset Union Connections (A2620090 or A2620045) 1. Remove the loosely fitted Manifold Supply and Return Ball Valves. 2. Thread Manifold Elbow Union (A2620090) or Manifold Offset Union (A2620045) connection into the Stainless-steel Manifold Assembly’s R32 union connection with a flat gasket. 3. Thread Manifold Supply and Return Ball Valve (A2771251 or A2771252) into the4R32 union connection on the 3 Manifold Elbow or Offset 2 Union Connection with a flat gasket. 1 4.
Connecting Tubing to the Manifold Connect the tubing to the manifold using either the ProPEX connection method or QS-style fittings. Refer to the Uponor Product Catalog for fitting information. ProPEX Connections 1 1. Use a PEX Cutter (E6081125, E6081128 or E6081501) to square-cut the tubing perpendicular to the tubing length. Note: Do not use a saw or similar cutting tool as shavings may clog the manifold valves. 2. Slide the ProPEX Ring over the end of the tubing until it reaches the stop edge.
Filling and Purging the Manifold To ensure proper system performance, it is important to fill and purge the system at the boiler or at the manifold. Refer to the following instructions to fill and purge at the manifold. 1. Connect a hose from a faucet to the fill valve on the supply manifold. 2. Connect a separate drain hose to the return manifold and place the other end into a large bucket or drain. 3. Remove the flow meter locking cover. 4.
Pressure Testing To ensure the system is installed correctly and operating properly, it is important to pressure test the system. There are several options to pressure test a system, including air and water. However, air provides a much more rigorous test. 1. To ensure all valves are working accurately, open and close all valves twice. Make sure all manifold isolation and flow valves are open. N ote: Manifold Supply and Return Ball Valves should be closed during the pressure test procedure. 4 2.
Balancing the Manifold Balancing the manifold helps to ensure proper system performance. 1. Ensure the system is operating and water is flowing through the manifold. 4 3 2. Remove the flow meter’s locking cover. 2 1 3. Turn the balancing valve to obtain the desired flow. Note: Visually check the flow meter window to ensure proper flow. 4. Replace the flow meter cover to set the valve position and push it down into the locked position.
