Initial Operation
Turning on the Dew Simulator
The Dew Simulator controller will turn on by activating the red switch at the bottom of the control. For the
controller to turn on, it must be connected to the cart harness. The perimeter nozzle controller will turn on by
activating the toggle switch.
Priming the system
1. Initial priming of the system should be done with the heaters turned off. Ensure Heater 1 and Heater 2 are
in the off position.
Ensure the 2” valve on the hose between the tank and the dew simulator is open, as well
as the ¾” valve returning from the warmup valve to the tank.
2.
Lower the reel so it is approximately 12” above the ground (below).
3. Turn the tractor PTO on and run at an idle. The pump will prime and start returning water back to the tank.
This will be indicated by the actual flow rate (GPM) being displayed on the screen.
4. When an actual flow rate (GPM) is displayed on the screen, a
ctivate the “ARM OVERRIDE” button on the
main screen. You may hear the 2way valve close. This will allow water to be pumped through the heaters.
Run the machine on
“ARM OVERRIDE” until the system fully primes and fluid starts spraying out of the
nozzles.
5.
Activate the “WARMING VALVE” button on the main screen. You may hear the warming valve open. This
will allow the water that is being pumped through the heaters to be bypassed back to the supply tank.
6.
Turn the “warming valve” button to the OFF position on the main screen. This will close the warming valve
and divert flow to the reel, which will pressurize. Once the reel starts spraying, the system is primed.
