 15. Air pressure to the spray head should be 60-90 psi

as indicated by the green area of the air pressure

gauge.

FLOW RATES

 16. Rate of formulation is controlled by a metering orifice

located in the fitting at the top of the formulation

tank. Additional fittings are located in a small

compartment on the base of the frame behind the

formulation tank.

 17. Orifice disk system-The orifice disc should be placed

inside the filter/orifice chamber, which is located in

the outlet of the formulation tank.

 18. To remove or change an orifice disc, first use (2)

” wrenches (one to hold the tank fitting, and the

other to unscrew filter/orifice chamber nut) then

remove nut and fluid line, then hold the smaller hex

nut using a wrench and loosen the hex retainer nut

and another 13/16” wrench to hold the tank fitting.

 19. Using a smaller orifice size will reduce the

formulation flow rate and using larger orifice size

will increase the formulation flow rate.

CALIBRATION

 20. Since the nozzle used is an external mix siphon

(suction) type nozzle, calibration must be made with

the machine running.
