Equipotential Connection; Water Installation Rules - La Cimbali M21 Junior DT/1 Gebrauch Und Installation

This type of connection, required by some laws, prevents differences in the electric potential level between the earthing connections
of equipment installed in the same room.
This machine is provided with a clamp underneath the base for connection to an external equipotential cable.
After installation, this type of connection MUST be made:
• Use a cable with a nominal section in compliance with the laws in force.
• Connect one end of the cable to the clamp (see
equipment.
Failure to follow this safety norm releases the manufacturer from any responsibility for machine breakdowns or damage to people
or property.
NOTE: DO NOT CONNECT TO THE POWER SUPPLY EARTHING BECAUSE IT IS NOT CONSIDERED AN EQUIPOTENTIAL
CABLE CONNECTION.
Bear in mind that Gruppo Cimbali S.p.A. is not responsible for damage caused by improper electrical connections,
and that the installer is responsible for any damage.
WATER REQUIREMENTS
Water used in coffee machines must be potable and suitable for human consumption (see laws and regulations in force).
Check on the machine's water inlet that:
• the pH level complies with the laws in force
• the chloride value is less than 100 mg/l
If the values do not fall within the limits, an appropriate water treatment device must be inserted (respecting the local laws and
compatible with the machine).
If the machine uses water with a hardness exceeding 8°F (4.5 °D), a specific maintenance plan must be implemented according
to the hardness detected and machine usage.
WARNING
Only use the supplied parts for installation. If other parts are installed, they must be new (not used) and they must be able to come
in contact with potable water suitable for human consumption (according to local laws in force).
WATER CONNECTIONS
Place the machine on a flat surface and stabilize it by adjusting and securing the feet.
Hook up the water connections as shown in the Illustrations chapter Figure 4, respecting the hygiene, water safety, and anti-
pollution laws in the country of installation.
Note: If the water pressure can rise above six bar, install a pressure reducer set at 2-3 bar. See Illustrations chapter Figure 5.
Water draining tube: place the end of the water draining tube in a drain with a siphon for inspection and cleaning.
IMPORTANT: The curves of the draining tube must NOT bend as shown in Illustrations chapter Figure 6.
