User Guide
Setting Shot Count
From the controller’s home screen, select the Settings icon and then select ‘Count’.
In the Count menu, the lifetime shot count of the machine is displayed as Total Shot
Count. A resettable shot counter for maintenance reminders is displayed as Shot
Count. For example, set the value of Shot Count to 300 as a reminder to replace your
group gasket once a year. Or, set the Shot Count to 20 as a reminder to backush
your machine once per week. This is completely up to the user to decide. When
the set number of shot cycles has been reached, the machine will read ‘Shot Count
Full’. When this message is displayed, reset the Shot Count to the desired number.
Resetting the Shot Count will not reset the Total Shot Count. Shot Count can be
monitored from the home screen under the current mode.
*When the shot count is full, please disregard the reminder to ‘Clean Level Sensor’.
This is not necessary in a home environment.*

Understanding the Brew Modes
Manual Mode
Navigating to Manual Mode
1. From the homescreen of the controller, touch the clock
2. Select the Manual Mode icon on the far right
Manual Mode allows the user to control pump pressure in real time throughout the
duration of a shot cycle. In Manual Mode, the user controls pre-infusion and brew
with their ngers via the rotary knob on the outboard controller. When the rotary
knob is moved just past the lowest position, the pump engages at its lowest possible
pressure, which is around 1-2 bars and around 4-5ml per-second water ow. Pump
power can be increased or decreased as desired throughout the entire cycle.
A common use of Manual Mode is to engage the pump at low power until full
saturation is reached, then increase power to 6-9 bars on the brew pressure gauge.
Nearing the nal 10ml-15ml of the shot, ramp down the power gradually, tapering o
brew pressure from 9 bars to 0 bars.
Auto Mode
Navigating to Auto Mode
3. From the homescreen of the controller, touch the clock
4. Select one of the two cup icons (Auto1 or Auto2)
In addition to a Manual Mode, the Zarre features two programmable Auto modes.
In Auto mode, the user is able to program Pre-infusion Time, followed by ‘Pre-infu-
sion Stop’, and lastly ‘Shot Time’. When in Auto mode, the shot cycle is engaged
by pressing the green droplet button on the front panel. It is not engaged from the
outboard controller like it is in Manual Mode.

12
User Guide
Controls in Auto Mode:
‘Pre-infusion Time’ translates to the amount of time that the pump kicks on in full
power at the beginning of the shot before entering the ‘Pre-infusion Stop’ stage.
When used correctly, this feature allows the user to quickly ll the brew chamber
under 0 bars to reduce headspace before transitioning into a low pressure infusion,
allowing the pressure ramp to start quickly. To launch straight into low pump power
for an elongated pre-infusion, Pre-infusion Time should be set to 0. To dial in Pre-in-
fusion Time, switch to manual mode, insert the backush disk into the portalter, and
determine how long it takes for the pressure to begin ramping after a shot cycle has
been initiated at full power. This value (which should only be a few seconds or less)
can be programmed as your Pre-Infusion Time in Auto mode. Utilizing Pre-infusion
Time in this way will help promote a faster saturation of the puck.
‘Pre-Infusion Stop’ translates to the amount of time that the pump operates in the
programmed low power (between 30%-60% pump power). A common way to use
Pre-Infusion Stop is to infuse the puck with low pump power just until espresso has
begun to ow from the basket.
‘Shot Time’ is the total shot time from beginning to end. Subtract the Pre-infusion
Time and Pre-infusion Stop times from this value, and the dierence is the duration
of full pump power following Pre-Infusion Stop. For example, if your full pre-infusion
cycle (Pre-infusion Time and Pre-Infusion Stop combined) totals 15 seconds and
Shot Time is set to 35 seconds, The Zarre will transition into full power infusion for 20
seconds. Shot Time can be set between 10 seconds and 120 seconds.
Other notes
Auto mode is not programmable by volume, only by time. Brew pressure at full pump
power is determined in part by the OPV valve inside the Zarre. Out of the box, with
the backush disk installed in the portalter, max power should be equivalent to
about 9 bars of pressure. To reduce max pressure, the OPV valve will need to be
reset. Contact sales@prima-coee.com for assistance if you desire a lower or higher
max pressure.

Frequently Asked Questions
Frequently Asked Questions
Q. Why does steam escape from the drip tray when the machine
powers on?
A. The vacuum breaker valve is doing its job to help pressurize the
steam boiler.
Q. Why is the power switch ickering?
A. Make sure the reservoir is lled with water, and also check if your
steam boiler is up to operating pressure. Until the reservoir is lled
and steam pressure is between 1-2 bars, the light will icker.
Q. Why does the Zarre make noise when turning on?
A. Make sure there’s enough water in the reservoir, but this noise is
the normal result of water moving from the reservoir into the vibratory
pump.
Q. Why does water leak from the grouphead during extraction?
A. Make sure your portalter is rmly locked in place. After a
number of months, the group gasket will wear down and will require
replacement.
Q. What parts need to be replaced as part of preventative
maintenance?
A. These parts include the group gasket, shower screen, baskets,
block spring, and the hot water and steam rubber rings.
