Fill with clean water at a temperature that does not exceed 50°C. Add liquid detergent in the amounts and using the
procedures recommended by the detergent manufacturer. Use only a minimal percentage of detergent to prevent
formation of an excess quantity of foam since too much foam may damage the aspiration motor.
Always use low foam detergent. Introduce a small amount of anti-foam detergent in the recovery tank before
starting to work to be sure to prevent foam from being generated. Never use pure acids. Put the refill opening
cover back in place after filling the tank.
