DETERGENT SOLUTION TANK
The capacity of the detergent solution tank is indicated in the technical
data.
Open the screw plug placed in the left part of the machine and fill the
detergent solution tank with clean water at a maximum temperature of
50°C (122°F). Add the liquid detergent in the percentage and conditions
foreseen by the manufacturer. To avoid excessive foam presence, which
could cause problems to the suction motors, use the minimum
percentage of detergent. Screw down the plug to close the solution
tank.
The switching on of the signal lamp of low detergent (19) indicates that
the detergent solution is nearly exhausted.
Use always low foam detergent. To avoid foam presence, before starting
working operation, introduce into the recovery tank a minimum
quantity of anti-foam product.
Never use pure acid.
