SETUP STEPS
1. The unit should be level (left to right - front to back), on a secure surface.

(In areas with extremely hard water, we suggest that a sedimentary and taste & odor lter be
installed.) This will prolong the life of your cappuccino system and enhance product taste.
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) so that the machine
can be moved for cleaning underneath.
2. This equipment is to be installed with adequate backow protection to comply with applicable
federal, state and local codes..

tons) on the front door will activate and the heating tank will start to ll.
