Water connection / draining
The water supply must be connected according to all valid regulations as well as national stipulations. If
the machine is connected to a newly installed water pipe, the pipe and the supply tube must be thoroughly
rinsed so that no dirt particles can enter the machine. The coffee maker must be connected to an installed
drinking-water pipe with shutoff valve. The machine is installed by using the mounted pressure tube and
the G 3/8“ screw at the pressure relief component mounted to the tap set to 0.3 MPa (3 bar). If the machine
is attached to a water drainage system, the supplied temperature-resistant drain hose must be connected
to the drip try and siphon. It must be firmly attached to the drain and slanted at a downward angle (so that
the water can flow downward).
Always use the new hoses supplied with the machine (fresh-/drain water hose)! Do not use old
fresh- and drain water hoses!
The water must be free of contaminants and the chlorine content may not exceed 100 mg/l. Do not use pure
reverse osmosis (RO) water or any other type of aggressive water. The carbonate hardness may not exceed 4 –
6°dKH (German carbonate hardness) or 7 – 10°fKH (French carbonate hardness) and the total hardness must be
always higher than the carbonate hardness. The minimal carbonate hardness is 4°dKH or 7°fKH. The pH value
must be between 6.5 – 7.
Water pressure
Recommended: 0.1 – 0.3 MPa (1 – 3 bar)
Maximum: 0.6 MPa (6 bar)
We recommend setting the pressure relief valve to 0.3 MPa (3 bar)!
Water ingress temperature
Minimum: 10°C
Maximum: 30°C
Fresh water and waste water tank (on mobile carts)
Capacity:•
Fresh water tank 16 litres•
Waste water tank 13 litres•
The fresh water tank must be filled daily with fresh, safe drinking water.•
Both tanks may only be operated at the designated location (level monitoring).•
Should its location change, the cart may not be pushed but must be pulled – for safety reasons.•
The cart is not designed for transporting cargo. Schaerer Ltd. accepts no responsibility for damage•
resulting from manipulation of the cart or from ignoring the user manual.•
Conditions for use and installation
Preparatory structural work must be commissioned by the machine supplier. It must be carried out by
licensed installers observing all general as well as locally applicable regulations. Schaerer Ltd. customer
service may only make the connections that have already been prepared. It is neither authorized to carry
out structural installation, nor is it responsible for its implementation!
Mains voltage tolerance 230 V (± 10 %), mains break < 50 ms no functional interruption
Protection IP 50
Water supply G 3/8 inch hose connection with main tap and dirt filter, water tempera-
ture max. 35 °C.
min. 0.1 MPa (1 bar) flow pressure at 2 l/min., max. 0.6 MPa (6 bar)
Water quality The water must be free of contaminants and the chlorine content may not
exceed 100 mg/l. Do not use pure reverse osmosis (RO) water or any
other type of aggressive water. The carbonate hardness may not exceed
4 – 6°dKH (German carbonate hardness) or 7 – 10°fKH (French carbonate
hardness) and the total hardness must be always higher than the carbon-
ate hardness. The minimal carbonate hardness is 4°dKH or 7°fKH. The pH
value must be between 6.5 – 7.
Water drainage line Hose at least DN 19, minimum slope 2 cm/m
Ambient temperature + 10 °C to max. + 35 °C (in the event of frost, drain the water system)
Humidity Maximal 80 % relative humidity
CAUTION!
Machine at risk!
