Safety notes

RISK OF DAMAGE TO THE MACHINE

Please comply with the following instructions in order to prevent technical problems or damage to the coffee maker:
► For water with a carbonate hardness of more than 5°dKH, a lime-scale lter should be con-
nected; otherwise the coffee maker could be damaged through limescale deposits.
For insurance reasons, always make sure that the main tap for the water supply (coffee maker
with xed water connection) is closed after operating hours have ended and that the main
electrical switch has been switched off or the power cord has been pulled out.
The device may not be operated if the water supply is blocked, since the boilers otherwise
cannot be relled and the pump runs "dry".
► To prevent water damage in the event of a ruptured hose, it is recommended to (structurally)
direct the water supply through a water stop valve.
After extended down times (e.g. holidays), the coffee maker must be cleaned before it is
placed in operation again.
Protect the coffee maker from weather conditions (frost, moisture, etc.). ► Malfunctions may only be rectied by a qualied service technician! ► Only use M. Schaerer Ltd. original spare parts!In devices with a refrigerator, the power supply must never be completely interrupted, or the
cooling function will not work.
► In the event of noticeable damage or leaks, notify a qualied service representative ap-
proved by the manufacturer and have faulty parts replaced and/or repaired! ► Never spray the device with water or any other fluid (e.g. steam cleaner)! ► Never immerse the device in water or in any other fluid! ► When using caramelized coffee (aromatized coffee), the brew unit must be cleaned at least
twice a day!
► If the coffee machine and/or auxiliary devices are transported at temperatures below 10°C,
the coffee machine and/or auxiliary devices must remain for 3 hours at room temperature
before it can be connected to a power supply and switched on. If this is not observed, there is
a risk of short circuits or damage to the electrical components as a result of condensation.
► Always use the new hoses supplied with the machine (fresh-/drain water hose)! Do not use old
fresh- and drain water hoses!

HYGIENE

Before using the coffee maker for the rst time, carry out the cleaning program (refer to User Manual, chapter Cleaning).
Observe the general applicable hygiene regulations according to HACCP! (HACCP= Hazard Analysis and Critical Control Point)
Coffee, milk and other contents:
► Do not use any raw milk! Only use pasteurized milk or UHT milk!
In all cases, the milk must be homogenized!
► Only use pre-refrigerated milk with a maximum temperature of 5 °C. If the milk is warmer than 5 °C, an optimal product cannot be dispensed. ► For hygienic reasons, it is recommended to use milk directly out of its original package. ► When using a milk container: Never top up milk; always clean the container thoroughly be-
fore relling it. ► Do not ll with more coffee or milk than is needed in a day. ► It is recommended to pour out remaining milk at the end of the day (if the milk was in contact
with the milk tube).
Before opening milk packages, check them for damage. ► Store coffee and products in a dry, cool and dark place. ► Use the oldest products rst ("rst-in-rst-out" rule of thumb). ► Use the products before their expiry date. ► Always seal opened packages tightly so that their contents will remain fresh and are protect-
ed from dirt.
► Store coffee and products separately from cleaning products. ► Close the bean hopper lids immediately after adding beans!

TIPS DURING OPERATION

Periodically press the button once shortly to initiate a brief flush cycle to clean and sanitize the Foamer. This is especially effective immediatly after peak dispensing hours.
Always start a rince cycle after replacing the Foamer!
Periodically rince the Splitter under warm, running water. This should be done at least once a day.
Machines without drain: The Drip Tray and Grill should removed and cleaned under warm, running water once a day.
Remember, the Drip Tray is not connected to a xed drain water connection so it can overflow
if not emptied! Make sure the Drip Grill is clean and free from milk residue.
Machines with drain:
The Drip Grill should removed and cleaned under warm, running water once a day. The Drip Tray should rinsed with water once a day. Make sure the Drip Grill is clean and free from milk residue.
Empty the Grounds Bin regularly and clean it under warm, running water when prompted by the Display.
Periodically clean the machine exterior (don’t use abrasives!) with a clean and sanitized cloth to remove residue from steamed Milk and Espresso shots.

When making two drinks at a time place two cups next to each other with the rims at the
center of the Splitter.

WATER QUALITY

GENERAL

99% of a cup of coffee is water. Not only because of the considerable influence water has on the
flavour of coffee, but also to protect the machine itself, special attention must be drawn to the
water.
The properties of water have a signicant effect on how your coffee is brewed, and on the life of
your coffee machine.

PURITY OF WATER

Water flows over rock and stone and through bedrock, where it gathers valuable minerals. The
source of the water, the bedrock and soil properties, and the local water treatment all affect the
properties and the flavour of water.
In preparing coffee, the pH level has a strong effect: acidic water emphasises the acidity of the coffee. Another phenomenon is that the crema disappears more quickly if prepared with water that has been fully softened. Not all machine parts are resistant to acidic water. Some can be­come corroded.
Water that is too hard can result in lime scale build-up in coffee machines (such as within the boil­ers and valves). Lime scale can impact the performance and shorten the lifespan of the coffee machine.
Depending on the scale of the
measuring tool the value must be
converted using the table right!

WATER CHARACTERISTICS FOR SCHAERER COFFEE MACHINES

5 – 7°dH (German hardness) relate to 8 – 12°fH (French hardness)
• If the measured value is below this range, the water must be mineralised.
• If the measured value is above this range, a descaling lter / softener must be used.
► Chlorine content max. 100 mg per litrePH value 6.5 – 7 (ph neutral)
Failure to observe these property ranges voids the M. Schaerer AG factory warranty!
