Introduction
Espresso Preparation System
Congratulations on choosing the Swift EPS
B from La
Marzocco. Your application of this new product in
your café or home will result in a number of
important benefits to you.
Quality, Consistency, Conservation, and Speed.
Your new Swift EPS
B grinds, doses and tamps coffee
directly into the portafilter, eliminating the need to
do this manually. It measures and doses by volume,
not time, so waste and product inconsistency are
reduced. At the same time, the Swift EPS
B enhances
coffee freshness by grinding coffee by dose, not by
bulk.
This manual includes information about how to
maintain and troubleshoot your Swift EPS
B for
optimal performance.
Please review it carefully.

Installation
The Swift EPSB
is easy to install. However, there are
several important considerations to keep in mind.
The Swift EPS
B
requires a grounded 110v, 15 amp (or
220v, 7.5 amp) power supply. It also requires a
minimum 16” x 16” (406 mm x 406 mm) space on
the counter. Since the unit is 26” (660 mm) in height,
allow at least 30” (762 mm) of vertical clearance so
there is sufficient space to allow the easy removal of
the bean hoppers and lids. The Swift EPS
B
weighs
about 75 lbs (34 kg), so make sure your counter will
support this.

(1) Install the bean hoppers and tighten the
safety screws.
(2) Plug the Swift EPSB into a grounded 110v or
220v single phase power supply.

There is no need to force it into position
Engage portafilter gently
Engaging the Portafilter
The portafilter engages directly to the Swift EPS
B.
Since the Swift EPS
B has no watertight seal, it is not
necessary to force the portafilter into place. Engage
the portafilter with only a light amount of force. If the
grinder shifts on the counter top, you are using too
much force.

bean hopper
Remove prepared portafilter
Operating the Swift EPS
B
Once the portafilter is engaged, press one of the start
buttons located at the front of the Swift EPS
B. The
right and left buttons correspond to the right and left
bean hoppers. Coffee will be ground, dosed, and
tamped from one of these locations, depending on
which button you press.
The red indicator lights located above the start
buttons are illuminated when the Swift EPS
B is
grinding and tamping.
Once the red light corresponding to the button
selected is no longer illuminated, you may remove
the portafilter from the Swift EPS
B and engage it into
the espresso machine.
The Swift EPS
B
tamps the coffee as it is ground. When
the volume of ground coffee in the portafilter reaches
the set level, the grinding motor turns off. The
tamping motor continues to run for 1-3 seconds,
“polishing” the tamped coffee.

Adjusting Coffee Grind
To achieve your desired brew time and coffee
consistency, a manual adjustment can be made to
the grinder to modify the grind of the coffee. (The
tamping pressure is not adjustable and remains
constant). Rotate the adjustor knobs as described
below.
(1) Locate the grinder adjustor knob that
corresponds to the left or right side of the grinder.
(2) Grinding the coffee more finely will result in a
slower pour. To achieve a slower pour, adjust the
knobs as follows:
Left bean hopper:
Turn the knob counterclockwise.
Right bean hopper
: Turn the knob clockwise.
(3) Grinding the coffee more coarsely will result in a
faster pour. To achieve a faster pour, adjust the
knobs as follows:
Left bean hopper
: Turn the knob clockwise.
Right bean hopper
: Turn the knob counter-
clockwise.
When making this adjustment, remember to turn the
knob in a minimum of half-turn increments.
Brew one or two shots to test the adjustment.
Note: There are many variables that can affect
coffee, including temperature, humidity, and
freshness of the roast. All of these can cause slight
variations in shot times.

Daily Cleaning
Daily cleaning of the Swift EPSB
is important to the
quality of your coffee beverages and to the
mechanical life of the equipment. When the cleaning
instructions are carried out each day, there will be
little chance of old coffee residue spoiling the flavor
of your espresso drinks, or interfering with the
mechanical operation of your machine. There are
three areas that must be cleaned: the bean hoppers,
the burr chamber, and the impeller.

shot extraction times, and the absence of noticeable
change in your espresso when adjustments are made
to the grinder.

Fuse replacement and Reset Switches
The Swift EPSB
has four fuses located at the rear of the
machine behind the removable panel. These
correspond to each of the grinder motors, the
tamping motor, and the electronic controls.
Occasionally it may be necessary to replace a fuse.
When switching fuses be sure to use only correctly
rated replacement fuses. Electronics = 1 ea. @ 125m
amps (normal); motor, grinder = 2 ea. @ 10 amps
GDC; motor, tamper = 1 ea. @ 1 amp GDC. On
machines with serial numbers 656 and higher, the
10 amp motor fuses are replaced with reset
switches on the exteror of the grinder. The head of
the switch will protrude when it needs to be reset.
Note: See page 31-32 for fuse sizes and locations.

TIPS AND TROUBLESHOOTING
What is the ideal shot time?
Shot time varies with all roasts and brew temperatures used to
brew espresso. Most likely, a minimum shot time is 18 seconds
and a maximum is somewhere in the 30 to 35 second range.
The ideal brew time for your coffee depends the coffee roast and
dose size. It is a relationship of bean solids and oils plus tamping
pressure and brew water temperature. Most of all, personal taste
preference should control shot time.
After brewing, re-engage the portafilter in the group.
Temperature stability at the portafilter will result in more
consistent pour times. The portafilter mounting area is a source
of heat which can benefit the brewing process when used to
keep the portafilter at temperature.
Clean
groups and portafilters daily.
Clean
espresso contact surfaces (screens and inserts) will result
in better flavored coffee.
Limit rinsing from the grouphead to one second or less.
Excessively rinsing the portafilter reduces the amount of hot
water available for brewing. An infusion of cold water into the
brewing vessel may temporarily lower water temperature below
the desired level. Since rinsing is usually undertaken as a way to
clean the portafilter, consider wiping the portafilter instead. If
you must rinse, do so with as little water as possible.
Watch the espresso you are brewing. Although making espresso
is partly a mechanical process, the outcome is determined by
organic factors like the coffee, the weather, the water, and your
ability to balance these. Defining and adhering to a set of fixed
parameters like brew time and shot size helps to ensure a
beautiful shot. However, ultimately the look and taste of the
espresso is the final arbiter of a shot’sacceptability. You must
determine when everything is just right.
