TANK
TAP
Water Supply Selector
14 Original instructions.
Important: To prevent limescale build up in the
boiler and other components, a water-softening
system must be installed in-line ahead of the
machine. Read more on section for water lter
requirements.
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. Never reuse damaged hoses
The default water supply mode parameter in the technical programming menu is set to use the machine in Tank mode.
Water supply mode must be adjusted once the machine is intented to be used plumbed:
- Dual mode (Not In US): Automatic water reservoir relling enabled if the machine is plumbed.
- Tank mode: Automatic water reservoir relling disabled. Water reservoir supply only.
- Net mode (US only): Plumbed mode only. Intended for machines with water supply selector.
Programming instructions available on Service Manual.
For specic US models:
This models have a manual selector located at the bottom of the machine that must be set manually if the machine is plumbed.
· Hydraulic supply selection
After the machine is connected of disconnected from the water mains, follow instructions of 'Hydraulic supply selection' section to
set up the machine accordingly.
Important: Machines equipped with the water inlet selector tap are
intended to work on ‘TANK’ (pour over) position or ’TAP’ (plumbed)
position. The automatic water reservoir dual function is not available on
these models and it will work like TANK ONLY’.
INSTALLATION AND START UP
1. Connecting the machine to the domestic water supply must be performed by a qualied person. Contact a service
technician to do this task you are not condent about performing the steps below.
2. Attach the included water inlet hose to the back of the machine and torque both ttings with a wrench (3/4" BSPP elbow
end to machine, straight end to 3/8" BSPP mains).
3. Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to ush out any
debris that may be in the plumbing system that would otherwise accumulate inside the boilers.
4. The domestic plumbing system should be tted with a brass 3/8” BSPP male pipe tting and an in-line shut-o valve.
Connect the 180cm water inlet hose included with the machine to the domestic water supply and tighten the line ttings
with a wrench to 15 ft. lbs. / 20N-m.
· Mains water connection
Note: For a suitable performance of the machine, maximum inlet water pressure must be 0.6 MPa (6 Bar) (87 psi). For
Norway, Sweden, Finland and Denmark, where the net pressure can reach 1.0MPa (10 Bar), install a pressure reducer in
case water pressure exceeds this range.
i
Pro Tip: Signicantly exceeding this operating range will result in excessive steam, high energy usage, unexpected
emergency machine shutdown due to safety valve activation and possibly premature machine failure. Setting the
temperature too low will resulting poor coee extraction, slow group boiler heating, and low/no steam.

tighten any leaking ttings.
Only use safe drinking water with a hardness rating between the parameters on the following table. If the hardness value is below
this limit, corrosion of hydraulic components is likely. If the value is higher, lime-scaling inside the boiler will occur. In both cases,
the proper function of the machine and quality and taste of the coee will be negatively aected.
If drinking water is not within the ratings shown above, a water lter must be installed inline ahead of the espresso machine.
Failure to install a water lter will result in voiding of the warranty and any damage resulting from limescale buildup will be the
responsibility of the owner.
