Johnston VT801 - Water Recirculation

An optional tap located on the Supawash manifold enables the body transfer duct to
be flushed through at high pressure.
With the re-circulation switch off and the Supawash activate, the high pressure water
will back flush the transfer duct into the body and expel the dirt through the large ball
valve on the rear door if opened, or into the body.
With the re-circulation switch on, the pipework from the transfer duct to the nozzle
can be flushed out at the same time.

This feature allows a first fill of an additional 750 litres of water to be carried within the body, which
can be re-circulated back to the body allowing longer on station working. In dry conditions the body
should be filled with water via the offside hydrant filler to the level of the tap (A) on the rear door.
Operating the switch will allow this water to be re-circulated via the nozzle whilst
sweeping.
