Operation Manual

3 At this time the indicator lamp closest to the center of the machine should be
illuminated. This is the low-water warning lamp and being illuminated at this
time indicates that the low water level safety system is operating properly.
Slowly and carefully begin to fill the reservoir. The use of a large funnel or
a pitcher with an easy-to-control stream is recommended. When there is ap-
proximately one inch (about 2.5 cm) of water, or possibly a little more in the
reservoir, the low-water warning lamp should go off. As soon as the lamp goes off:
3a Turn the power switch to “Position 0.” Look inside the reservoir. The water level should be just covering
the intake filter. This verifies that the switch is properly adjusted and working as designed.
3b Finish filling the reservoir to within about 1/2” of the top.
CAUTION: If the lamp did not turn off, stop, turn the power switch to “Position 0”, unplug the ma-
chine, and contact your reseller for technical support.
Priming the Pump
Rotary pumps were not originally intended to draw water from a reservoir. Because of that, it is a good
idea to prime the pump this first time to be sure that it will correctly draw water from the reservoir. It is not
always necessary to do this when first starting up a new machine, but it insures that the pump is protected from
running without water. Follow these directions to prime the pump:
5 Lift the hose out of the reservoir and remove the filter from the end of the hose.
6 Hold the hose straight up and using a suitable tool (turkey baster, syringe, or small funnel for example)
completely fill the hose with water.
7 While still holding the filled hose upwards in one hand, turn the power switch to “Position 1” and lift the
brew lever all the way. Almost immediately, the water in the hose should be drawn into the pump. As soon
as the water level in the hose begins to recede, immediately lower the brew lever fully and turn the
power switch to “Position 0.”
8 Replace the filter on the end of the hose and drop it into the reservoir
Initial Filling of the Boilers
9 With the reservoir filled, lift the brew lever fully and turn the power switch to “Position I.” You should hear
the pump begin to run immediately you should see the water level begin to drop in the reservoir. In thirty
seconds or less, water should come from the group. As soon as it does, lower the brew lever all the way. The
pump might continue to run because the DD is filling the steam boiler. If the level does not begin to drop
right away, lower the lever to turn off the pump and turn the power switch to “Position 0,” and return to Step
5, “Priming the Pump,” and repeat that procedure.
WARNING: If the reservoir level does not begin to drop within the first five seconds, lower the brew
lever completely and turn the power switch to “Position 0”. Unplug the machine, and consult your
reseller for technical support. Leaving the machine on with no or low water in either boiler can
damage the machine! This type of damage is not covered by the warranty.
10 When the pump stops, recheck the reservoir’s water level. Because the DD’s steam boiler is quite
empty upon delivery the first refill will use more water than subsequent activities.
NOTE: Remember to regularly check the water level of the reservoir.
11 When the pump stops and the reservoir has been refilled, lift the brew lever to the brew position (fully up).
The pump will run again and water will once again issue forth from the group and flow into the drip tray.
When the flow is strong from the group, lower the lever fully. When the lever is lowered, the pump should
stop and the flow of water stops as well.
12 Check the level of water in the reservoir and refill as necessary.
