Operating - Quick fill / purge system

Quick fill (optional)

An optional quick-fill system can be fitted to allow filling from a external, high capacity pumped bowser system.

A camlock connecter is fitted to a 2" ball valve situated near the main control valves on the near side of the sprayer. A drop pipe is fitted into the tank so liquid is pumped in below the level in the tank to avoid foaming.

On some machines the quick fill may also be connected to the water self fill so that the clean water pumped in can also be circulated through the chemical inductor giving clean water for can washing

The purge system is fitted to allow air and clean water to be purged from the boom spray lines and to fill them with fresh chemical ready for spraying. It is only necessary to use it when starting from scratch and when changing chemical.

The system is controlled by the main suction valve on the near side of the sprayer. When this is set to the Purge position it does several things:

a) It opens a microswitch to change the position of an additional electric ball valve which in turn connects the sprayer control manifold to the main suction valve.
b) It opens a port in the main suction valve to connect the manifold directly to the pump.
c) It opens all the electric boom section valves.
e) It isolates the flowmeter (if fitted) to stop it recording additional volume on the spray monitor.

After filling the spray tank with water and chemical and after allowing sufficient time for it to agitate and mix, simply turn the two main valves to the positions shown above and wait for approximately 30 seconds. This can normally be done whilst spray cans etc are tidied away.

Liquid is then drawn backwards through the spray lines and sprayer controls and is directed back into the tank. It is drawn into the spray lines through a series of non-return valves which block the pressure once the flow is reversed again for spraying.

When spraying is commenced you can start moving straight away knowing that the piping system is full of chemical.
