Rocket R 58 Dual Boiler espresso machine
Most dual boiler PID espresso machines measure the water temperature used for the
extraction in the brew boiler. The boiler temperature reading is then converted into a
“group extraction” temperature. This information is misleading and inaccurate, as
the digital readout does not display the real temperature at the group rather the
temperature the manufacturer wishes the user to see.
Rocket Espresso measure the boiler temperature and display the boiler
temperature.

(*) The “SCASE” Thermofilter elevates the art of espresso by employing applied
measurement science. Very convenient brew temperature measurements are now
possible through use of the Thermofilter. The results of these measurements enhance
machine optimization for specific coffee blends, enable individual coffee shops to
establish enhanced quality control procedures for their machinery, and increase
knowledge of the thermal behaviour of espresso machines. This knowledge is
immediately useful in compensating for intermittent duty machine behaviour. The
Thermofilter enables performance comparisons of different espresso machines and
technologies by use of systematic testing protocols. Accurate temperature studies
will result in new machines with enhanced tuneability and stability that produce
better taste than ever before.
The Holy Grail of temperature devices? Well, let’s just say, that this is the state of
the art of something big. How big? Nobody knows for sure. However new machines
coming to the market are being evaluated with this device, and the current World
Barista Championship (WBC) and United States Barista Competition (USBC)
technical standards teams all use this device to test and evaluate the machines used
in competitions.

Instructions for use
This machine has been designed for the sole purpose of producing
coffee, hot water and steam for hot beverages.
All other uses are outside of the scope of this machine and, therefore,
dangerous and hazardous.
The machine has been designed from safe, accessible, durable
components and materials and manufactured to the highest standards
for use only in home / domestic environment.
The machine should not be exposed to elements such as sunlight, rain,
snow, extreme temperatures etc.
The machine must be operated by responsible adult persons who know
the use of the equipment and should not be used by children, minors or
untrained persons.
To protect against electric shock do not immerse machine, cord and
plugs in water or other liquid and do not ever let the machines
internal parts come in contact with liquids.
The user should be fully conversant with safety operating procedures
contained in the manual and should follow the instructions and advice
provided with.
To ensure maximum performance efficiency, it is essential that technical
service and maintenance is carried out exclusively by Rocket Espresso
Ltd. authorised technicians.
It is the responsibility of the user to notify the manufacturer of any
defects or damages which may affect the safety of the original
installation or future safe operation of the machine.
The user must respect the safety regulations at the point of installation.
The user must check the surrounding areas to ensure safe and hygienic
use is guaranteed.
The machine component’s manufacturers are responsible for the parts
supplied by them. The customer is responsible for the personal use of
the equipment.

It is the responsibility of the user to ensure that the location of the
machine is hygienic, and that its continued safe operation can be
guaranteed.
When the machine is not being used for long periods of time, the
hydraulic systems should be drained completely and the machine stored
in a temperature above freezing (0°C or 32°F). This will prevent the
hydraulic system from freezing which could damage internal pipes and
boiler.
This appliance is intended to be used in household and similar
applications such as:
• staff kitchen areas in shops, offices and other working environment
• farm houses
• by clients in hotels, motels and other residential type environments
• bed and breakfast type environments
If the appliance should be connected to the water mains:
• The maximum inlet pressure is 0,4 MPa
• The minimum inlet pressure is 0,1 MPa
• You must use the new hose-sets supplied with the machine. Do not
reuse old hose-sets.
All spare parts fitted to the machine must be original Rocket Espresso
Ltd. components.
Before any cleaning or maintenance the machine should be
disconnected from the electric supply.
Never pull the electrical supply cable.
When cleaning the machine never use caustic or abrasive cleaning
chemicals.
To avoid electric shocks:
• Do not immerse machine itself, cord and plugs in water or other liquid
and do not ever let the machines internal parts come in contact with liquids.
• Ensure that the machine is installed with a proper earth/ground in
accordance to local safety practises, codes and legislation.
• Prevent the power cable from being stretched, or pulled tight.
_____________________________________________________________________________________________

• Avoid using the machine with wet hands.
• Never operate the machine with bare feet.
Never operate the machine without ensuring the water reservoir contains
water.
The machine must be operated with soft, clean drinking water. This
means that there must be a minimum content of mineral in the water. If
the local water supply has a high mineral content use a water softener. A
build up of mineral deposit may restrict the flow of water within the
hydraulic systems causing damage to the machine and risking personal
injury.
The machine must be switched off whenever it is left unattended.
