2.3 Electrical connection
•
There must be an omnipolar type of main switch that
disconnects all contacts, including the neutral, with a distance
of at least 3 mm between the open contacts and with safety
circuit breaker tripping or connected with fuses, to be sized or
calibrated in conformity with the power indicated on the machine’s
data plate.
•
The main switch must be located on the electric line close to the
place of installation, and it must serve only one appliance at a time.
•
Electric network voltage and frequency must coincide with those
given on the data plate.
•
There must be an effective earthing system in conformity with
the prevention standards in force for operator and equipment
safety.
•
The power supply cable (type H07RN-F only) must not be pulled or
crushed during normal operation or routine maintenance.
•
The unipotential terminal fastened to the body must be connected to
a unipotential cable having a section suited to the application.
•
Respect the polarities indicated in the wiring diagram.
•
Consult that attached wiring diagram for additional information.
Do not use adaptors, multiple socket outlets or cables of inadequate type and
section or with extension connections not compliant with plant engineering
standards in force.
2.4 Plumbing connection
The appliance is to be connected to the water network with a hose.
There must be a slide on-off, ball or gate valve able to quickly and
completely turn off the water if necessary between the water network
and the appliance’s solenoid valve. The on-off valve must be on the line
near and just before the appliance.
•
If the system is new or nearly so, let the water run a long time before making the connection.
• The water supply, temperature and pressure must be compatible with what is indicated on the
machine’s technical data plate.
•
If the water’s hardness is greater than 14 F (8 dH), we recommend you install an external water
softener upline of the solenoid valve.
2.5 Connection to the drain line
•
The drain line must be made up of a free water trap of a size
proportionate to the delivery of the drain pipe supplied with the
machine. The pipe must be able to reach the water trap without
being pulled, squeezed, bent, crushed, pressed or forced in any
way
.
•
The tank empties by gravity, so the drain must be at a lower level
than the base of the machine (525mm).
