6. 3 Operating instructions CAUTION J Never point the sprayjet against persons Wearing eye protection is strongly Wy recommended Spraying procedures cause noises depending on the used pressure If necessary wearing of ear protection is recommend WARNING Danger caused by combustible and noxious spraying material Safety instructions on fluid can and material data of fluid manufacturer must definitely be observed The automatic spray valve ASV needs 3 5 6 bar control air pressure Atomizing air pressure and material pressure should be as low as possible In any case please observe the regulations of the rofessional trade association having liability for industrial safety and insurance When you are certain that fluid pressure stands up to the nozzle actuate 2 2 way solenoid for atomizing air After that actuate 3 2 way solenoid for control air This way you reveive socalled pre air prior to opening fluid flow After each cycle solenoids are to actuate in reverse order so you will still have purging air after needle has closed nozzle and fluid flow was stopped This prevent fluid to form out drops instead of being atomized Set atomizing air pressure and fluid pressure according to required spray droplet sizes Two separate pressure reducers must be available Intermittend use as well as continuous use is possible Maximal 40 cycles per second are possible under optimal working conditions IMPORTANT The quantity
