3. Operating with detergents
a) Chemical intake via built-in injector:
The rotary knob (19) on the control panel must be turned clockwise as far as the stop CHEM and
the chemical/detergent hose immersed in the chemical tank. The water flow rate is automatically
reduced to approx. 200 litres/h for chemical intake. It is not necessary to change the nozzle. If you
want to work with max. water flow and high pressure, turn the rotary knob (19) anti-clockwise to the
stop position.
The amount of chemical/detergent added to water can be infinitely varied at the metering valve (11)
up to a concentration of 35 %.
Important: Return the rotary knob to the high pressure position after finishing work in chemical
intake mode.
b) Chemical intake via the machine:
Prepare water and chemical mixture in the required ratio in a tank and the draw in the mixture my
means of the pump. After finishing the job in hand, run the machine for at least one minute with clear
water in order to flush remaining chemical out of the machine.
