Key facts

• Supplied assembled with wall brackets, pressure gauge and automatic air vent
• 2 to 12 ports, one per loop
• Stainless steel bars, 3/4" Eurocone outlets at 50mm centres
• 210mm flow to return spacing, the usual UK spacing
• Flow meters reading 0 to 5 L/min on the flow bar; adjusting caps on the return bar swap for actuators
• Fill and drain valves at the bar ends, 1" inlets for isolating ball valves

How to fit it

1. Pick a central, accessible spot with room for pipes to bend up
2. Mount level on the wall brackets, then fit the ball valve set or pump pack
3. Cut each pipe square, ream it and fit a Eurocone core
4. Flow to the flow bar, return to the same port on the return bar
5. Pressure test every loop at 4 to 6 bar and keep it under pressure while the floor is laid
6. Fill and flush each loop until it runs clear
