Introduction
First of all, thank you for your business! You are going to love your new QM67 Dual Boiler
Espresso Machine. It combines classic beauty, value, and great performance for making the
best espressos, cappuccinos, and lattes you’ve ever tasted! These instructions include tips
that will help bring out the Barista that’s hidden within! Enjoy your new machine!
First Time Set Up
•Before using your machine, test your water for hardness using the provided test strips.
Fill a glass with cold tap water; dip the tip of the test strip into the water for one second,
then pull the strip out of the water and hold it horizontally for fifteen seconds. After fifteen
seconds, compare the color of the strip to the chart on the side of the package to
determine how many grains of hardness is in your tap water. Three grains or less of
hardness is acceptable to be used in the machine.
Note:Should your water’s hardness level exceed three grains, then it is strongly
recommended that an in tank softener be used or a different source of water that has
been tested for hardness. Some bottled water can be extremely hard and should always
be tested before using. Using a Brita or PUR style pitcher or faucet filter does NOT
remove any hardness from the water and should only be used in the machine if your
water source is under 3 grains of hardness. Using hard water in the machine will affect its
performance and may cause damage to the machine which is not covered under
warranty.
•Open the hinged reservoir door on the top of the machine and remove the water
reservoir. Rinse the water reservoir out and fill with cold softened water and then install it
back into the machine being careful not to spill any water inside the machine.
•Be sure that both silicone lines are sitting in the bottom of the reservoir like shown. There
is a notch on the right side of the reservoir for the lines to sit in and the float should be on
the left side of the machine.
•Make sure the silicone lines are not pushing
the float down or the PID and heating lights
will not turn on.

First Time Set Up, Continued
•Before plugging the machine in, verify the steam and hot water knobs are closed and
the brew lever is in the down position. Also make sure the power switches are in the
off position and the drip tray is in place.
•Plug the machine into the outlet*and then turn the coffee boiler power switch to the
on position.
•The pump will come on to fill the boilers and then will turn off after the boilers have
completed filling.
•If the pump turns off and the PID and heating lights do not come on then the water
reservoir needs to be refilled. It may take 2 reservoirs to completely fill both boilers.
•After the boilers have finished filling then place whichever portafilter you intend to use
into the group head. Then lift the brew lever to activate the pump and keep the lever
up until water comes out of the portafilter for at least 15 seconds and then lower the
brew lever.
•The heating indicator light and PID will illuminate and the machine will start heating.
You will hear some gurgling noises and a small amount of steam and water will be
discharged into the drip tray. This is normal to allow for the release of air and the
expansion of water in the boiler.
•If you plan on steaming milk or using the hot water wand then also be sure to turn on
the steam boiler power switch. The coffee boiler power switch must also be on for the
steam boiler to operate.
•The machine should reach temperature in approximately 15 minutes, but to make
delicious espresso with thick rich crema it is necessary to allow the machine to be
heated for 30-45 minutes with the portafilter kept in the grouphead.
*The electrical outlet must be a 3 prong 115V grounded outlet. No adaptors or extension
cords should be used. A timer may be used to turn the machine on and off, but it must be a 3
prong grounded timer rated for 15 amps. A GFCI outlet is highly recommended but is not
necessary.

Before Each Use
•Verify the steam and hot water knobs are both closed and your brew lever is pointing
straight down.
•Fill the reservoir with cold softened water.
•Place whichever portafilter you intend to use into the group head and then turn the
coffee boiler power switch to the on position. If you plan on using the steam or hot
water wand then also turn on the steam boiler power switch.
•Let the machine warm up for 30-45 minutes for optimal performance.
Normal Operation
Gauges
•The top gauge is for your boiler steam pressure. After turning the machine on it will
take approximately 15 minutes before the gauge will show any pressure. Once up to
pressure the gauge will cycle back and forth roughly between 1.2-1.7 bar depending
on the steam boiler temperature setting. Should you need to adjust the steam
pressure please refer to the PID section of the owner’s manual.
•The lower gauge is for your pump (brew) pressure. When sitting idle the gauge is
reading trapped pressure in the system and may vary. To get an accurate pump
pressure reading install your backflush disc in the portafilter and lock it into the
grouphead and then raise the brew lever. After a few seconds the pressure should
rise to about 9 - 10 bar. When you make espresso the pressure on the gauge will be
slightly less at about 8.5 - 9.5 bar which is normal. This can be helpful in setting up
your grinder. If your pressure goes to 9 - 10 bar with the backflush disc, but when you
make espresso it is less than 8 bar then that means you need to go finer with your
grind which will create more resistance to raise the pressure. Should you need to
adjust the pump pressure please refer to the maintenance section of the owner’s
manual for instructions on setting the pump pressure.

Normal Operation, Continued
Lights
•On the front of the machine there are 4 indicator lights. The green indicator light to the
left of the coffee boiler power switch will illuminate whenever the coffee boiler is
turned on.
•The green indicator light to the right of the steam boiler power switch will illuminate
whenever the steam boiler is turned on. The coffee boiler power switch must be
turned on for the steam boiler to operate.
•The red coffee boiler heating indicator light located under the coffee boiler power
switch will illuminate whenever the coffee boiler is heating.
•The red steam boiler heating indicator light located under the steam boiler power
switch will illuminate whenever the steam boiler is heating. The coffee boiler must be
up to temperature before the steam boiler is able to heat.
•It is normal for the red heating lights to flash rapidly back and forth to maintain the
proper temperature in both boilers.
Pump
•The machine is equipped with a 52W vibratory pump that is thermally protected.
Vibratory pumps can be loud by nature and their tone may change during the course
of a shot which is normal.
•Periodically the pump will come on by itself to maintain the proper water level in the
boiler. Sometimes the pump will come on when you turn on the machine and
sometimes it may not depending on the water level in the boiler which is normal.
•The pump (brew) pressure is regulated by the expansion valve. To learn how to set
the pump pressure please refer to the maintenance section of the owner’s manual.

Normal Operation, Continued
Water Reservoir
•The water reservoir can be accessed by opening the hinged reservoir door on the top
of the machine. It is recommended that the reservoir be removed prior to filling to
prevent the spilling of water inside the machine which can cause damage to sensitive
electrical components. Should water accidently get spilled inside the machine then
immediately turn the power switch to the off position and unplug the machine from the
electrical outlet. Do not plug the machine back in until it has had at least 1 full day to
dry out. If it does not operate after that time then unplug the machine and refer to the
troubleshooting section of the owner’s manual.
•The reservoir must be installed properly for the machine to function. The float inside
the reservoir must be on the left side of the machine. Also be sure the reservoir is
seated as far down as possible and the silicone hoses are not pushing the float down
or the PID and heating lights will not turn on.
•The machine is equipped with a magnetic float in the water reservoir to detect the
water level. When the water level gets low the PID and heating lights will go out and
the pump will no longer function until the reservoir has been refilled.
•The reservoir should be cleaned at least once a week with mild dish detergent and
rinsed thoroughly before use. DO NOT PUT IN DISHWASHER!!!
•Depending on your water quality it may be necessary to periodically sanitize the
reservoir or if you are using hard water and have a mineral build up inside. White
vinegar can be used to sanitize and will also remove the mineral deposits that can
accumulate. Fill the reservoir with white vinegar and then let it sit for an hour and then
rinse and clean the reservoir thoroughly. If the reservoir still has a vinegar taste or
odor you can mix some baking soda and water in the reservoir to remove the taste
and odor and then wash it with a mild dish detergent and rinse thoroughly.

PID Controller
The PID controller’s display will cycle back and forth to
show the current temperature of each boiler. The
position of the decimal point (2+3) indicates which
boiler the temperature is being shown for at that time.
The picture to the right shows which boiler is
represented by which decimal point.
The down arrow is used to cycle through the various
settings and the up arrow allows you to select a setting
to change. After selecting a setting to change the
up/down arrows must be pressed within 2-3 seconds
or the display will revert back to the previous setting.
Setting Temperature
With the machine turned on press both arrow keys simultaneously until the display reads T1
then release the keys. T1 is the coffee boiler temperature. Press the up arrow key to see the
current temperature setting. While the temperature is still being displayed press either arrow key
to change the temperature.
After a few seconds the display will revert back to T1, then press the down arrow key to display
T2 which is your steam boiler temperature. Press the up arrow key to see the current
temperature setting. While the temperature is still being displayed press either arrow key to
change the temperature.
After the display reverts back to T2 then press the down arrow key to save the new temperature
settings and go back to normal operation.
Coffee Boiler Temperature - By default the coffee boiler temperature has been set to 200°F
The recommended brew range is between 195°- 205°F or 90°- 96°C. This can be easily
changed to match the coffee blend you are using and to bring out the different flavor
characteristics in the coffee. A hotter temperature will bring out more of the bittersweet
chocolate flavors and going colder will bring out more of the fruity flavors. Going too hot may
cause the shot to taste bitter and going too cold it may taste sour. Experiment with different
temperatures until you find the one you like best.
Steam Boiler Temperature - The steam boiler temperature has been set to 263° by default
which is approximately 1.7 bars of steam pressure. The pressure may vary slightly at different
elevations. This setting should never be changed unless the machine is at a higher elevation
and the pressure exceeds 2 bar in which case the temperature should be reduced by a few
degrees so it does not exceed 1.8 bar.

Advanced PID Settings
Warning - This section allows the user to change the machine from Fahrenheit to Celsius mode
as well as other advanced settings that can greatly affect the performance of the machine.
These settings have been calibrated using specialized test equipment and should not be
changed unless the user has a thorough understanding of how a PID controller operates.
To get into the advanced programming
mode, with the machine turned off hold
down both arrow keys and then turn the
machine on. Keep holding the arrow keys
until the display reads F.01 and then
release the keys.
Use the down arrow key to cycle through
parameters and then use the up arrow key
to select a parameter to change. Then use
the arrow keys to change the selected
parameter.
To save the new changes turn the machine off and then back on again.
PID Basic Theory - The PID calculation algorithm involves three separate constant parameters,
the proportional, integral, and derivative values. These values can be interpreted in terms of
time: Pdepends on the present error, Ion the accumulation of past errors, and Dis a prediction
of future errors based on the current rate of change. These 3 settings work together to
determine when and how to apply power to the heating element to allow for a more precise
temperature control. It is not recommended to change the PID settings unless you have a
thorough understanding of how a PID controller operates. To learn more about PID controllers
visit the following link. http://en.wikipedia.org/wiki/PID_controller
Offset- The coffee boiler offset setting has been calibrated using a special Scace device and
should not be changed. The steam boiler offset setting is set to 0° by default. It can be changed
up to 5° to increase the steam pressure, but the pressure may vary at higher elevations so make
sure it does not exceed 2 bars of pressure.
Note - The PID controller and heating lights will turn off when the reservoir is empty.
