• Turn the knob of the piston to unblock it and pull it
towards you.
• Turn the bottom of the tap a few degrees to release it
and pull it towards you. Unscrew the steel piston pin
and disassemble all the parts of the piston. Remove
all the O-rings.
• Emerge the previously disassembled components
into the tub with the sanitizer and brush the surfaces
with care. Pay special attention to the inner duct of
the tap, to the holes and seats of the OR.
SANITIZING FIXED PARTS
While the removable parts soak in the sanitizer
inside the tub, proceed sanitizing the fixed parts of
the machine:
SANITIZING THE TUB
• Immerse a disposable paper cloth in the sanitising
liquid.
• Pass the cloth over all the surfaces of the tub and
fixed transmission shaft.
• Pass the cloth over the outer edge of the tub until
reaching the surfaces of the cover and front panel.
• Use the brush previously emerged in the sanitizer
to thoroughly clean the drain duct which connects
the tank to the tap.
