7.2.3 Water supply connection - Characteristics

Fresh water supply features:
Table 1
Connect the machine's water supply with an interrupt valve capable of quickly and completely shutting off water intake.
*It is compulsory to install a water-softener, in case of water with average hardness above
be cleaner and the machine will last much longer.
The machine can be equipped with a water softener, on request. If the machine is equipped with a water-softener, a
regeneration of the resins shall be done on regular basis (see par.
N.B.: Any damage caused by limestone (calcareous water higher-up than 8°f and without water-softener) will not be covered
by warranty.
A periodical check of the supplied water hardness is highly recommended.
**Machines shall be made with extra power in case of cold water infeed.
***The water supply temperature shall never exceed 55°C.

7.2.4 Water supply characteristics

The machine water supply must be potable, in compliance with Directive 98/83/EC.
The inlet water must also meet the parameters given in the table 2.

life of the machine.
Desired value: Out of range values might lead stainless steel blackening/tarnishing.

It is recommended a water test once a year.

7.2.5 Steam evacuation

In accordance with regulations of environmental hygiene, for the proper functioning of the machine and a healthy environment
for the operator who working in there, it should be at least 10 air volume changes per hour in the room where the machine
is installed.
For small wash rooms we recommend at least 15 air volume changes per hour.
