Water and Cleaning System
Thewaterisfedtothehigh-pressurecleanerunderpressure(2-8barpre-pressure).A
floatvalveregulatesthewaterflowinthestoragetank.Thenthewaterissuckeddirectly
fromthestoragetankbythehigh-pressurepumpandforcedwiththeadustedpressure
throughtheheatexchangertothesafetyspraylance.Thehighpressurejetisformedby
thenozzleattheendofthesafetylance.

Kränzle technology
Lance with trigger gun
Themachinecanonlybeoperatedwhenthesafetytriggerissqueezed.Whenthelever
issqueezed,thespraygunopens.Theliquidisthenpumpedtothenozzle.Thespray
pressureincreasesandquicklyreachestheselectedoperatingpressure.Whenthetrig-
gerisreleased,thetriggergunclosesandanyfurthersprayingofliquidfromthelanceis
stopped.Themotorstops.
Whenactuatingthegunoncemorethepressurecontrolvalve-safetyvalveclosesand
themotorisstartedagain.Thepumpresumesfeedingwatertothesprayinglancewith
theselectedoperatingpressure.Whenthegunisclosed,thewaterhammeropensthe
pressurecontrolvalve-safetyvalveandthemotorisswitchedoffbythepressure
switch.
The trigger gun is a safety device. Repairs should only be performed
by qualified persons. Should replacement parts be required, use only
components authorized by the manufacturer.
