MACHINE INSTALLATION
1. Ensure the machine is unpackaged and placed on a hard and
stable surface near an adequate power supply.
2. Remove the water reservoir cover and ll the reservoir with
ltered water, pouring from a very clean water jug with a spout
that is easy to pour from. Be careful to pour water into the
water reservoir only (to remove the reservoir for cleaning see
maintenance instructions). Replace the cover of the water
reservoir. Rocket Espresso recommend the use of the Rocket
Espresso water lter.
3. Connect the machine to power supply that is rated in accordance
with the serial plate on the espresso machine.
4. Turn the on/off switch to the ‘on’ position ‘1’. Boiler water ll
begins – you will hear the pump noise. Place the portalter in the
group.
5. Allow 20 to 25 minutes warm up time. When the machine is ready
the temperature will be displayed on screen 1 of the touch screen.
The correct operating temperature and pressure should be
+/- 92°C or 197.6°F displayed on the touch screen, with a service
boiler pressure of +/- 1 bar.
6. Place a cup underneath the group and turn the paddle to release
a cup of hot water from the group - rst time use only. Close the
hot water by returning the paddle to the start position.

MACHINE INSTALLATION
CONNECTING TO MAIN WATER SUPPLY
The R NINE ONE is preset at the factory to use the supplied 1.9 litre
water reservoir.
To connect the R NINE ONE machine to mains water supply, use
the steel braided water hose provided and ensure the following
instructions are adhered to:
1. Use a certied plumber to complete the installation and
ensure that the installation meets local authority standard and
regulations in all cases.
2. Line pressure exceeding 4 bars should be limited with the use of a
pressure regulating valve on the water feed line.
3. Use a shut off valve to isolate the water supply to the machine.
4. If you are drawing water from a non pressurised system (ie. from a
remote water supply tank, not mains pressurised) t a non return
valve to the end of the water supply hose to ensure that the line
pressure is maintained at all times.
5. Use an in line lter to ensure the water supply of the machine
is of the highest quality - ask your plumber what he would
recommend.
6. Once the mains installation is complete it will be necessary to
switch the machine from tank to water supply.

SETTING THE COFFEE VOLUME
PORTIONS (volumetric portion control)
A ow meter allows the machine to calculate the precise coffee
volume you would like from the single or double porta lter. (Generally
25 to 30ML from the single porta lter and 50 to 60 ML from the double
porta lter). When you are sure the grind setting is correct you can set
the ow meter.
It is important to understand that the volumetric portion control will
differ between each pressure prole. The ow meter will count total
water volume irrespective of the time it may take.
Example; Pump pressure of 9 bar over 30 seconds will yield a different
total volume than 5 bar over the same 30 seconds.

Pg 28 Pg 29Pg 29
PRESSURE PROFILES
The R NINE ONE pressure prole system allows up to 5 time interval
and pressure adjustments to be made over the course of the
extraction.
It is therefore possible to increase / decrease the length of time and
change the pressure for each interval. For example:
1. Press symbol.
2. Press to select the prole you wish to edit.
3. Press to scroll from time to pressure.
4. Press to increase or to decrease seconds or pressure.
5. Press to conrm (save) and to return to home screen.

MACHINE OPERATION
1. Install the portalter by inserting it into the group head and
rotate the portalter handle from left to right. The portalter is
inserted properly once it is rmly inside the group head and the
portalter handle is sitting at 90 degrees from the face of the
machine (Fig G).
2. You can now turn the group control paddle to start the water
owing through the portalter.
3. It is important to leave the portalter installed in the group
head when not in use. The portalter must remain heated for a
successful brew process. It will also prevent the head seal inside
the group head from drying out prematurely.
4. Single (with one spout) and double (with two spouts) portalter
handles come ready assembled with single and double baskets
tted.
5. You are now ready to start brewing coffee by removing the
portalter and placing ground coffee inside the lter basket.
Press down on the coffee with the supplied tamper and install the
G
portalter in the group head. Turn the paddle to release heated
water and start the brewing process..
6. To stop the brewing process return the group control paddle to
the starting position so that the water stops owing.
7. To heat milk dip the steam tip 1under the surface of the milk
which is contained in a stainless milk jug. Release heat into the
milk by pulling the steam handle 2forwards so the valve is fully
open. Once the milk is at a good temperature for consumption
push the lever back to the upright position. Remove jug from
under the steam wand.
8. In order to prevent heated milk from being sucked into the
boiler it is recommended that you purge the steam wand after
heating milk. Purge by releasing steam for a few seconds into the
atmosphere.
9. To dispense hot water press the hot water symbol 3on the
touch screen and release the required amount of water into a cup
or vessel. To stop the hot water press the hot water symbol on the
touch screen. CAUTION THE WATER IS VERY HOT.
10. More details of brewing coffee and steaming milk are outlined in
the Mano section of this Rocket Espresso handbook.

MISCELA
The coffee blend
1. Ideally coffee beans should be consumed between three and
fourteen days from roasting. In the rst three days the beans are
still releasing carbons from the roasting process.
2. From fourteen days the coffee will start to lose its avor
characteristics to become old and stale tasting.
3. Store your coffee beans in an airtight container in a cool dark
place. Do not refrigerate or freeze.
4. Blending is to combine coffees from two or more countries of
origin.
5. Espresso coffee should be a harmonious blend of sweetness,
acidity and bitterness.
6. Espresso roasts tend to be slightly darker than lter or French
Press roasts as a darker prole emphasizes body and sweetness.
MACINATURA
The grinding of the coffee blend
1. An espresso grind is a very ne grind yet still granular.
2. Coffee loses its avor rapidly once ground therefore only grind as
much as is needed for the next espresso beverage.
3. Temperature, humidity and wearing of the grinder burrs all affect
the accuracy of the grind setting, therefore each morning you
may nd you need to ‘dial-in’ your grinder (make the grind setting
coarser or ner) This will be the difference between good coffee
and great coffee.
4. It is important to have a good burr grinder with a fully adjustable
grind setting.

MANO
The skilled hand of the barista
What is espresso?
• Espresso is a 25-30ml (50-60ml for a double) beverage prepared
from 7-9 grams (14-18 grams for a double) of coffee through
which clean water of 90.5 °-96.1°C has been forced at 9-10
atmospheres of pressure, and where the grind of the coffee is
such that the brew time is 20-30 seconds.
• While brewing, the ow of espresso will appear to have the
viscosity of warm honey and the resulting beverage will exhibit
a thick dark, golden crema. Espresso should be prepared
specically for, and immediately served to its intended consumer
(as dened by the Specialty Coffee Association of America).
HOW TO MAKE BEAUTIFUL ESPRESSO
1. Place fresh coffee grounds into the portalter basket until full or
overowing.
2. Knock the handle on the tamping mat once to settle the grounds.
3. Evenly distribute the grounds to a level ush with the rim of the lter
basket. Release any excess grounds back into the doser hopper.
4. Compress the grounds with a tamper, pressing rmly, then
twist the tamper to smooth the surface of the grounds. Tamp
pressure should be around 30kg so the applied pressure should
be very rm.
5. Rocket Espresso lter baskets have a reference line inside
them, that the grounds, once tamped, should be level with.
Continued over page...

Pg 36 Pg 37
FLOW RATE & GRIND SETTING
• Ensure that your dosing and tamping is consistent.
• Good extraction is characterised by a 5–10 second delay before
any coffee will pour. Heavy droplets will appear and develop into
a thick, straight and even pour. The colour will be dark brown or
hazelnut, preferably with a reddish reection (see page 33).
• The pour should be cut off before the colour lightens and the
