All Hunter Industries Anti-Siphon Valves should be installed above ground and at least 6 to 12 inches above the highest sprinkler to prevent back pressure or drainage. Installations at any height lower than this may result in unsafe backflow conditions. Consult your local codes to verify this height for your specific area. Do not install any other shut-off valves between the anti-siphon valve and the sprinkler heads. Do not bury this product. In areas where freezing conditions occur, make provisions for draining the system by using both a drain valve and a stop-and-waste shut-off valve installed on the mainline feeding the sprinkler system. To assure complete drainage of the valve after the water supply is shut-off, electrically energize each valve for at least 2-3 minutes. This will vent the upper cavity of the valve allowing maximum drainage. The ASV-075 and ASV-101 Anti-Siphon valves are rated for use up to 150 PSI at 110˚ F. The flow control can be used to reduce the downstream pressure on high-pressure installations.
