Rinse all parts thoroughly before replacing in the machine. Screw
the dispersion disk in using the coin, but do not over-tighten. A snug fit
is sufficient.
Long Term Storage
The brew boiler and steam boiler contain water. Because of that, if
the Double Domombar is not going to be used for a while or is being
placed into storage some factors must be considered.
The first is environmental temperature. If it can be avoided, the
machine should never be stored where it will be subjected to freezing
temperatures. If there is water in the machine that freezes, there is a potential for a tremendous amount of
damage. As the water turns to ice it expands with great force. The pump, all the internal metal pipes, and both
boilers face destruction from this expanding force.
WARNING: Freeze damage can destroy a machine. Pipes can burst and the boilers can be ruptured.
Freeze damage is not covered by the warranty.
It is very difficult to remove all the water from the machine, and it is a job best left to a technician. The
best solution to the problem is to avoid leaving the machine in a place where it is subject to freezing. If you
know that it will be left in freezing conditions check with your local RV supply store. They sell anti-freeze
chemicals designed to be used in drinking water systems. Be sure that the additives are safe to use on copper,
brass, plastic, and chrome parts.
CAUTION: If using an anti-freeze chemical, tape a warning message over the power plug as well as
to the face of the machine warning of the addition of these chemicals and to completely flush the
machine before use!
WARNING: Damage from these sorts of chemicals is not covered by the warranty. Use of these
chemicals and storage in freezing conditions is done at your own risk.
Even if not stored in such extreme conditions as mentioned above, when placing a stored machine back
into service you must flush out the machine with fresh water to remove any stale water. If the machine has just
been sitting unused for a while, it is best to replace the water in the boilers. Pull about 10 ounces (300 ml.)
through the group to flush out the brew boiler, and dispense about 30 ounces (.9 L.), 6 ounces (175 ml.) at a
time, through the hot water wand to refresh the water in the steam boiler.
