Installation:

• Refer to Specifcations Tab for installtion guide
• Can be installed in any orientation.
• Do NOT install in the ground.
• Do NOT apply heat near valve during installation.
• Valve may require adjustment on site. To increase pressure turn adjusting screw clockwise (1 ½ turns = 1 metre head).
• Valve must be either valve vented or open vented.
• For increased flow rates or inlet pressure below 200 kPa [29psi], two valves in parallel may be required.
• Where two valves are in parallel, each must have isolating valves on inlet.  

Inlet: 15mm, 1/2" BSP (male)
Outlet: 20mm 3/4" BSP (male)
