The MP Rotator has a lower precipitation rate than typical spray heads, so your run times need to be lengthened. Your run times with the MP Rotator may be two to three times longer than a standard spray zone. This is because the MP Rotator puts water down at a slower rate resulting in a significant reduction in runoff, thus saving large amounts of water.

Looking at performance data charts you can see MP Rotator vs. a Spray Nozzle at 40psi.

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.

You can manually test proper operation of the rain sensor by using the One Touch Manual Start. During the Manual All stations cycle, press the test button on the “Clik-type” sensor (eg. Mini-Clik®) to interrupt watering.

Note: The rain sensor will only interrupt watering in Manual All Stations and automatic programming.  Manual single station will override the sensor circuit.

The most common reason for a valve to remain on, or weep, is debris. New installations without proper flushing, recent mainline repair, or well water can cause debris to flow into the valve and get caught between the diaphragm and the seat. Check for debris using the following steps:

The WVP controller uses a numbered seven-day calendar to schedule the days to water. The display will show the days of the week as numbers 1–7.

When programming the current time and day, you can select a number to represent the current day of the week. The number can be changed to represent the user's preference. Many people use Sunday as day 1 while others use Monday as day 1. The day number can be set to whatever works best for you.

The HUNTER ADJUSTMENT WRENCH consists of a 3/32 Allen key, two convenient finger loops for gripping, and an opposite side arc adjustment key for all your Hunter rotor adjustments. The Hunter wrench can be purchased from your local distributor. You can also use a 3/32 Allen key for radius adjustment only.
