*Should the water supply pressure be more than 60 PSI (400Kpa), a pressure reducer must be installed (only for those
versions where it is not a standard supply, already).
**
It is compulsory to install a water-softener, in case of water with average hardness above 8°f.
Washed objects will
be cleaner and the machine will last much longer.
Note:
Any damage caused by limestone (calcareous water higher-up than 8°f and without water-softener) will not be covered
by warranty.
Once a year a supplied-water hardness check is highly recommended.
***
The machine must be supplied with cold water, if equipped with the Heat Recovery System (max 59°F - 15°C).
Machines shall be made with extra power in case of cold water infeed.
****The water supply temperature shall never exceed 150°F - 65°C.
Connect the machine draining hose to the connection located low on the side (see pict. 3),
making sure that the water fl ows freely (giving, therefore, minimum slope).
Should not be possible to drain the water at a level lower than the appliance outlet
(see pict.
3), it's advisable to choose a machine provided with a drain pump.
The drain tube shall always be connected to a siphon in order to prevent the release of odors.
Maximum drain height = 31 inches (0,80 mt - see pict. 3).
2.3.3 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.
1
Out of range values might lead to corrosion and jeopardize the life of the machine.
2
Should the water hardness is higher
it is compulsory
to install a water softner and check periodically its operation.
3
Out of range values might lead scaling and sediments with a consequent lower performance, functionality, and expected
life of the machine.
4
Desired value: Out of range values might lead stainless steel blackening/tarnishing.
5
For machines equipped with Heat Recovery System.
It is recommended a water test once a year.
2.3.4 Electrical connection
Only qualifi ed and properly trained personnel can operate on the electric board and connections.
Before the installation:
Make sure that the voltage is the same as reported on the data-plate.
Make sure the line voltage matches the machine power and voltage indicated on the machine data-plate (as shown on par.
1.2
).
Electrical connection must be carried out in compliance with the current local standards.
IT IS STRICTLY FORBIDDEN TO CONNECT THE MACHINE'S VENT DIRECTLY WITH THE OUTDOOR!
COLD WEATHER CONDITIONS MIGHT SERIOUSLY DAMAGE THE THERMAL RECOVERY SYSTEM AND
THE STEAM CONDENSER.
