1. Walk the field to determine if wet spots are visible.

II. Control Lights and Manual Switch Positions

1. Open the control panel and open the lid to the hydraulic unit.
2. Make sure all manual switches are in the automatic position.
3. Microprocessor on; power light and run light
4. Microprocessor input; see owners manual table
5. Microprocessor output; only when in operation

III. Pump Tank Liquid Level

1. Check liquid level in pump tank to confirm switch operation. If a float is down its light should be off.

IV. Pump and Valve Operation

1. Place pump "Hand-Off-Auto" switch in the "Hand" position to dead head pump against valves. The flow meter should not turn, and there should be no leaks.
2. With the pump running, place each zone valve in the "Hand" (open) position one at a time to check operation. With the zone valve open, flow should register on the flow meter. When the zone valve closes (off position), the flow should stop.
3. With the pump in the "Hand" position open the filter backwash valve for filter one (1) for 10 seconds then close. Repeat for filter two (2) position for 10 seconds. There should be no flow registering in the flow meter and you should hear the valves open and close. The valve diaphragm will rise then lower during backflush.
4. Return all switches to the automatic position.

V. Extended Check - Zone Dose Rates

1. Open the air release valve boxes and inspect. Make sure they close during dose (they should not leak water after air is evacuated).
2. Determine how many zones are in operation and the installed flow rates from the installation records.
3. With the pump in the "Hand" position, select the first zone by placing the zone valve switch in the "Hand" position. After pressurization time, check flow rate by reading the flow meter for a timed minute. Repeat for all zones. If flow varies by more than 10% from original flow rate, contact qualified operator.
4. After the final zone is checked, place the "Zone Return" valve in the "Hand" position while the zone valve is still in the "Hand" position and verify that the flow rate increased to provide field flushing.
5. Return all switches to the automatic position.
6. Press reset button for 5 seconds and check zone dosing time.
