Crem EX2 - Mains Water Connection; Water Filter Requirements

Original instructions.
INSTALLATION AND START UP
Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness degrees).
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.
· Water lter requirements
· Mains water connection
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. 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.
3. The domestic plumbing system must be tted with a brass 3/8” NPT male pipe tting and an in-
line shut-o valve. Connect the 180cm (70.86 inch) 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.
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
1. Ensure that a water ltration 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 condent about performing the steps below.
2. Open the water tap and allow the lter to ll (if new/previously unused). Then the machine’s
steam boiler will begin to ll. Check carefully around the service area for leaks or drips. If leaks/
drips are detected turn o the tap immediately and check/tighten any leaking ttings.
3. If necessary, connect the machine to a water softener to reduce water hardness using the
exible 55cm (21.65 inch) hose included in the accessory box.
Filtration device
Important:
Always maintain the water ltration device or system in accordance with the manufacture’s
specications. Failure to routinely maintain the ltration device or system will result in
limescale build-up inside the machine’s hydraulic system which will eventually result in
machine failure. Please read more under the cleaning and care section.
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.
