SOLUTION WATER

Fill the solution tank with clean water at a temperature not more than
50° C and add liquid detergent in the proper concentration following
the instructions of the manufacturer. Excess foam in the recovery tank
could damage the suction motor, so use only the minimum amount of
detergent necessary.
ATTENTION! Always use low foam detergent. To avoid the
production of foam, before starting to clean, put a minimum quantity
of antifoam liquid into the recovery tank. Never use pure acid.
