Detergent dosage
Detergent is drawn in directly on the suc-
tion side by the high-pressure pump out of
an external detergent reservoir.
The metering amount is set at the deter-
gent metering valve (2) in the unit. The set
value corresponds to the proportional amount
of detergent in the jet spray.
Important!
To vent the detergent suction line, turn the
metering valve to position 4 %.
For faster venting compress the suction
hose at the float tank while pump is run-
ning.
The following graphs show the amount of
detergent drawn in for the positions of the
metering valve.
