Operation Manual

NOTE: For those users who choose to plumb the machine, Chapter 11 details setting up and starting
the machine using the plumb option. Chapter 10 should first be followed by all users to verify that
the reservoir option also operates correctly.
Why Use The Reservoir?
With all the benefits of a plumbed machine, why use the reservoir? There are situations where you may
have no choice. It may be that the water available is too harsh and you cannot install a treatment system. Or
possibly you are in a location that does not allow installing the necessary plumbing lines, such as in a rental
property.
Additionally, users who choose to plumb the DD will eventually use the reservoir option to temporarily
supply the machine with a chemical mixture to descale the machine which is discussed in detail in Chapter 20.
Switching to the reservoir makes it a very easy matter to run the descaling solution through the boilers without
having to remove the outer case cover.
Whichever water source you choose, by moving the lever (whether to the reservoir or the plumbed posi-
tion), the other source is isolated and will not supply water to the machine. Whichever you choose as your
primary water supply, be sure to consider the quality of the water to ensure long life of your Vibiemme DD.

Plumbed
Details are given on setting up and using the Plumbed source in a later Chapter 11. But be aware that each
community has various requirements regarding how to connect plumbing, so if you are planning on connect-
ing the machine directly to the water supplied to your home, consult a licensed plumber. It is important that if
the pressure of the water source varies or exceeds about 40 PSI (3 BAR), that you use a pressure regulator that
is set to approximately 40 PSI (3 BAR). High pressures can cause leaks and may result in damage. Irregular
pressure can lead to inconsistent results.
WARNING: Damage to the machine caused by improper plumbing, high pressure, particulate mat-
ter in the water, or other similar water-source problems is not covered by the warranty. These can
also create hazardous situations such as leaks occurring inside the machine.
CAUTION: Improper plumbing techniques or design can cause leaks which can damage property.
These leaks and the damage that can be caused are not covered by the warranty.
