OMNIE Manifold Install Guide
| Stage 1 - Storage and initial assembly |
|---|
NOTE: If it is necessary to store the system once you have taken delivery, ensure it is kept in the following conditions:
Following the CAD design locate the manifold(s) securely fix the manifold to the wall, allowing a minimum of 500mm from the floor to the lowest point of the manifold unit (preferably allowing space either side and in front for ease of maintenance). Next securely fit the the pair of isolating valves respectively into the mixing unit with the taps facing forward, the lower fitting (22mm compression fitting supplied see note) has a parallel thread, fit this into the lower part of the isolating taps, here you will require a suitable thread sealant (Loctite 55 Pipe Sealing Cord, Loctite 577 thread sealant or PTFE tape). primary pipework from the heat source can now be installed into these fittings making sure of the orientation of the flow and return are correct. NOTE – The primary circulator and heat source must be sized correctly and capable of providing sufficient water to the manifold location. If no mixing valve and circulator are being used then the primaries are connected (arms only) directly to the manifold. |

| Stage 2 - Flow Rate Control Valve & The Thermostatic Actuator |
|---|
Adjust the manual mixing valve to the designed temperature from the design drawing for each manifold. The accurate temperature will be displayed on the temperature face at the top of the manifold. The Flow Rate Setting should be as follows: For a condensing boiler temperature at 55°C the dial should come pre-set with the 3 aligning with the notch in the housing (adjust if required).
For a higher temperature heat source around 75°C turn the dial so the 5 aligns with the notch in the housing.

|
| Stage 3 |
|---|
If not already done, install floor pipe circuits in accordance with the design layout drawings, ensuring sufficient pipe is exposed from the floor to reach the manifold. Curved pipe bends are available to support the pipe as it leaves the floor up to the manifold. Each pipe must be labelled with the circuit number and the room it serves for identification purposes. |
|
| Stage 4 |
|---|
Cut pipes to the correct length, it is recommended that the underfloor heating and primary pipe work is flushed prior to connecting to the manifold to remove any debris that might otherwise cause a blockage. Please note: cuts should be made with a pipe cutter and should be cut as straight as possible, not at an angle. |
|
| Stage 5 |
|---|
Fit the monoblocco connectors on to the ends of the pipe and offer up into the appropriate port on the manifold. |
|
| Stage 6 |
|---|
Push the pipe with monoblocco connection into the seat on the manifold and tighten by hand. |
|
| Stage 7 |
|---|
Using the supplied spanner tighten the connection whilst maintaining upwards pressure on the pipe. These may need to be re-tightened after several heating and expansion cycles. |
|
| Stage 8 |
|---|
Check all manifold joints are tightened and sealed as they may have become loose in transport. Once connected, it is recommended to insulate all primary pipe work. |
|
| All pipe circuits should now have been connected |

BEFORE CONTINUING, COMPLETE THE CONNECTION CHECKLIST BELOW:
The system can now be hydraulically filled (with water, not air) and purged of air see – IG UFH 27.1 Please ensure you complete and return the pressure testing form (on the next page) to validate your warranty – PT UFH 01.1 |
