8.1 HyGIENIC CLEANING
Hygienic cleaning solution preparation
• Prepare 5 litres of water
• Add to it 5% of “hydrogen peroxide” at 130 volumes; for the doses, use a
graded measure or an ordinary syringe
NB: if you use commercial hygienic cleaning solutions, keep to the instructions
provided by the manufacturer and included in the package.
• Turn off the red switch S (to 0)
• Let at least 5 litres of water flow out of the “HOT” outlet to cool down the hot
circuit.
• With the help of a pump P, connect the appliance’s water inlet to the container
with the disinfecting solution.
• Start up the pump, letting the disinfectant flow into the machine, and open the
AMBIENT, COLD and HOT outlets to let the solution flow through all parts of the
hydraulic circuit to the outlet nozzle.
• Before the solution runs out, stop the pump and interrupt the dispensing.
• Leave the solution to do its work for minimum 20 minutes.
• Reconnect the appliance to the mains water supply.
• Let at least 15 litres of mains water flow out of the AMBIENT, COLD and HOT
outlets to thoroughly rinse the water system before re-using the machine.
• Check correct flow of water from the hot water tank then turn the red switch S on
again (to I)
