Operation Manual

7 The reservoir platform’s center screw has to be tightened until the

microswitch clicks. This closes the low-water safety switch allowing

the machine to operate without water in the reservoir. Slowly tighten

the center screw while carefully listening for the water-level safety

microswitch to click. After the click, turn the screw at least one more

additional turn. If you do not hear the click, loosen the screw fully and

try again, tightening the screw until the audible click occurs.

8 Connect the included braided water hose to a cold-water source. The

large ﬁtting on the supplied steel-mesh, reinforced hose has a female

end 3/8” BSPP threads (British Standard Parallel Pipe) so an appropri-

ate adapter is required (not included - contact your reseller).

CAUTION: This machine is only designed to draw in cold water.

The pump can be damaged by being supplied with heated water.

Damage to the pump from hot water is not covered by the war-

ranty.

CAUTION: Be aware that the pump is not designed to draw wa-

ter against gravity so if you are intending on using a self-contained water source (such as a large

water bottle) it is recommended to use a pump system to supply the source water under pressure to

the machine. Damage to the pump from insufﬁcient water supply is not covered by the warranty.

9 Before connecting the other end of the supply line to the machine, hold the free end of the hose in a suitable

container (like a pail or bucket) and have someone else turn on the supply line’s shutoff valve (that valve

is not part of the DD and is not included with the DD). Run approximately one gallon of water through the

hose to clear it of any loose debris, Teﬂon tape bits, or any other foreign debris to keep this from entering

the machine.

CAUTION: Water can come from this hose with sufﬁcient force to cause the hose to come out of the

container and spray water about the area. Water damage is not covered by the warranty.

CAUTION: An inline particle ﬁlter is highly recommended. The pump as well as valves and other

parts of the machine can be damaged by grit, sand, or other similar foreign matter in the water.

Damage caused by water that is not ﬁltered is not covered by the warranty.

CAUTION: Line pressure should be no more than about 40 PSI. Higher pressures can force the

water reﬁll valve to open which can overﬁll the steam boiler.

10 Turn off the water supply.

11 Remove the protective cap on the 90 degree ﬁtting on the bottom on the DD (cap not shown here), and

ﬁt the smaller end of the included braided

hose to the ﬁtting. Use Teﬂon tape to assure

that the threads are sealed. Do not allow any

Teﬂon tape to be placed in a way that could

possibly allow the Teﬂon to get into the water

stream and subsequently into the DD’s water

system.

12 Check that the brew lever is in the off posi-

tion (moved fully down), and turn the supply

valve for the water supply back to the on posi-

tion. In a short time you should see the brew

pressure gauge on the right side of the panel

indicate the line pressure. This is normal.
