There are two lights on the Wireless Rain Clik Receiver, and each has its own purpose.

USA
The ICZ-151 is the largest drip zone control kit Hunter manufactures, this provides up to 60GPM @ 40 psi (Gallons per Minute)(227 l/min) per zone.

Calculate the application rate of each similar zone by using the following formula:

 

USA

The Air/Vacuum Relief Valve (AVR) is designed to reliably discharge air during system start-up and allow air into the line during shutdown. The valve closes even with low water pressure and reduces water hammer.

USA

Regulating pressure saves water and extends the life of the irrigation system. Water savings is achieved by operating each zone at the best pressure for that equipment and application type. Use the chart below to select the best Accu-Sync™ model for each application of Hunter irrigation equipment. Accu-Sync ensures that every zone in every system stays in check for maximum water savings and longevity.

 

USA

Water enters the valve from the system main line and exerts a force against the center of the valve’s diaphragm. A small orifice in the diaphragm allows the water to flow through to the upper chamber between the diaphragm and the bonnet. The water continues to travel on through a port in the bonnet to the solenoid area. The solenoid has a light spring loaded metal piston that, when the valve is closed, covers the inlet port hole.

USA

In most installations, the Wind-Clik acts as a switch to break the circuit to the solenoid valves of the irrigation system during high wind conditions. This allows the timer to advance as scheduled, but keeps the valves from opening the water flow. Once the wind conditions drop below the reset point, the switch closes again to allow for normal operation. This is performed by the wind action of the vanes. They rotate about 180°, and DO NOT SPIN.

USA

The correct placement of the Freeze-Clik is critical for accurate temperature sensing. It must be mounted out of direct sunlight, and where free outdoor air circulation is possible. Examples would be the north wall of a building or under eaves and overhangs.
