INSTALLATION AND START UP
1.
Connecting the machine to the domestic water supply must be performed by a qualified person.
Contact a service technician to do this task you are not confident about performing the steps
below.
2.
Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to
flush out any debris that may be in the plumbing system that would otherwise accumulate inside the boilers.
3.
The domestic plumbing system should be fitted with a brass 3/8” NPT male pipe fitting and an in-
line shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic
water supply and tighten the line fittings with a wrench to 15 ft. lbs. / 20N-m.
4.
Ensure that a water filtration device or system is installed in-line in the domestic water supply
ahead the machine to prevent contamination inside the machine’s hydraulic system. Contact a
service technician to do this task if you are not confident about performing the steps below.
5.
Open the water tap and allow the filter to fill (if new/previously unused). Then the machine’s
steam boiler will begin to fill. Check carefully around the service area for leaks or drips. If leaks/
drips are detected turn off the tap immediately and check/tighten any leaking fittings.
6.
If necessary, connect the machine to a water softener to reduce water hardness using the flexible
55cm hose included in the accessory box.
Important:
Use the inlet hose included with the machine to connect it to
the water mains in accordance with the national rules applicable
in the country where machine is installed.
Water connection checklist
Pro Tip:
Always maintain the water filtration device or system in accordance with the manufacturer’s
specifications. Failure to routinely maintain the filtration device or system will result in limescale
build-up inside the machine’s hydraulic system which will eventually result in machine failure.
