Flow Chart
Installation
- Refer to Technical Area for
installation 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
˝ turns = 1 metre head).
- Valve must be either valve vented or open vented.
- For increased flow rates or inlet pressure below 200 kPa [29 P.S.I.], two valves in parallel may be required.
- Where two valves are in parallel, each must have isolating valves on inlet.
