12. SUGGESTIONS FOR OBTAINING GOOD COFFEE
To obtain coffee of satisfactory quality, it is important for the water used to have a value of 4-5 °F (French degrees). If the water hardness is
greater, the use of a softener is advisable.
Avoid using the softener if the water hardness is less than 4 °F.
If the taste of chlorine in the water is especially noticeable, a special filter should be installed.
It is not advisable to keep large amounts of coffee beans, nor to grind large amounts of coffee. Set aside the amount in the container and if
possible use it before the end of the day. Do not purchase pre-ground coffee as it expires in a short amount of time.
After the machine has not been used for a relatively long period of time (2-3 hours) cycle through a few dry runs.
Always carry out periodic cleaning and maintenance.
13. LIST OF HAZARDS
This chapter describes possible hazards for the user if the specific safety standards described in this booklet are not adhered to.
The appliance must be connected to an efficient grounding system
If this is not done, the appliance can be a source of dangerous electrical discharges in that it is no longer able to discharge electricty to
earth.
Do not use running water to wash
The use of pressurized water directly on the machine can seriously damage electrical appliances. Never use water jets to wash any part of
the appliance.
Be careful with the steam nozzles and hot water
During use, the steam nozzles and hot water may overheat, thus becoming a source of danger. Handle such parts carefully. Never direct
steam or hot water jets directly on parts of the body.
Do not intervene on the machine when it is supplied with electrical power.
Before carrying out any intervention on the machine you must turn it off by means of the main network switch or better yet, disconnecting the
connection terminals in the network. Never remove any body panel when the machine is supplied with electrical power.
Never work on the hydraulic system before having emptied it.
All work regarding the hydraulic system and the relative boiler are to be avoided when there is still water and pressure in the system. You
must therefore empty it beforehand, closing the mains cock and dry-running the delivery group for a short time. Switch off the machine and
open all the steam and water cocks and taps. With the pressure zero, completely empty the boiler, unscrewing the special pipe fitting situated
on the lower part of it.
If the above procedure is not correctly carried out, opening any part of the hydraulic system can cause a sudden outlet of overheated water
under pressure.
Lever machines
Never lower the lever if there is no coffee in the filter, or if the filter holder is not installed on the group: the sudden upwards movement of the
lever may damage the appliance and injure individuals.
Gas machines
Periodically check for gas leaks in the system by applying a soapy solution to the ducts.
For safety reasons, close the gas heating system when the machine is not in use (at night or during hours of closure)
Use of the appliance
This espresso coffee machine is an appliance exclusively for professional use. Any other type of use is considered wrong and therefore dan-
gerous. Never allow children or incapable persons to use the machine.
Non-observance of the above-described standards can cause serious damage to people or animals.
Never work on the electronic apparatus when the machine is still supplied with electrical energy.
Shut down the machine completely by unplugging it from the mains before carrying out any operation.
