INSTALLER SECTION
1.2 Receiving the machine
Pay special attention in choosing the lifting points and the machine barycentre during the loading and
unloading operations.
Before accepting the machine, verify that all the data on the data-plate corresponds to the required ones
(as shown on par.
1.1
) and to the ones of the available electrical supply.
After unpacking, make sure the machine has not been damaged during transportation. If so, do notify the
seller immediately about the problem. If the damage might question the machine safety, do not install it.
Double check the firm tightness of all hose-clamps on piping, nuts, bolts and electrical connection
that might have come loose during transportation, to prevent water dripping leakages, or other damages, during
the machine operation.

for disposing the packing material.
1.3 Storage
Storage temperature: min. +40°F (+4°C) – max. +122°F (+50°C) - humidity <90%
The stored parts should be checked periodically to detect any sign of deterioration.
Do not store the machine exposing it to atmospheric agents (rain, sun, cold, etc.). Do not place material on the packed machine.
1.4 Prepare for installation
This is just a guide-line for the machine installation. The installation must be performed by a qualified engineer.
1.5 Water connections
Water connections must be carried out in compliance with current local standards.
The Water system must have characteristics between the parameters specified in table 1.
*If higher than 60 PSI (400Kpa),
it is mandatory
to install a pressure reducer.
To improve the machine performance keep the temperature intervals indicated.
It has to be installed a water supply shut-off valve close to the machine in an accessible point.
Use only new flexible pipes for the water connections.
1.6 Water supply characteristics
The machine water supply must be potable.
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.
It is recommended a water test once a year.
