X20 Sprayer Reference Manual

4.Screw the Pressure Relief Adjuster in (clockwise), until the dial pressure gauge on the Sprayer registers 1 Bar (approximately 100kpa) more than the maximum rating of the nozzles. Eg:: If the nozzle pressure range is rated at 1-4.5 Bar, set the relief valve to a reading of 5.5 Bar.

The system will never have a pressure exceeding the displayed pressure, thus protecting the Sprayer and the operator.

The rate will be achieved, from the OFF position, in approximately 3 seconds, thus eliminating under sprayed areas.
