The network of pipes and hoses, the water pump and the reuse
tank must be of a non-corroding material. It must be resistant to
water and chemicals used for washing.
The tank must be equipped with a system that fills the tank with
clean water to a minimum required working level, in case the wa-
ter level drops below this minimum. If this requirement is not met
and an insufficient or no amount of recuperated water is fed into
the washer, it will not function properly.
A pump must transport the recuperated water from the tank to the
washer. The requirements for the pump depend on the number
and type of washers that are connected to the water re-use sys-
tem. The maximum pump pressure is 116 psi [8 bar].
It is advisable to install a level switch. This level switch must be
connected to the microprocessor by means of a potential-free
contact. Refer to

The relay contact K1 has to close when the water level is too low.
Terminal B is positioned on the left side, in the lower part of the
microprocessor. Terminal A is positioned directly above Terminal
B. The microprocessor is positioned inside the washer. If the
"Check signal recycle" parameter is set to "yes" in the configura-
tion menu, the timer will send a signal if the water level of the
reuse tank is too low.
Electrical Installation Requirements
IMPORTANT: Electrical ratings are subject to change.
Refer to serial plate for electrical ratings information
specific to your machine.
NOTE: The machines are not designed for use in an IT
network.
DANGER
Electrical shock hazard will result in death or serious
injury. Disconnect electric power and wait ten (10)
minutes before servicing.
W911
WARNING
Dangerous voltages are present inside the machine.
Only qualified personnel should attempt adjustments
and troubleshooting. Disconnect power from the ma-
chine before removing any cover and guards, and
before attempting any service procedures.
W736
WARNING
Hazardous Voltage. Can cause shock, burn or death.
Verify that a ground wire from a proven earth ground
is connected to the lug near the input power block
on this machine.
W360
IMPORTANT: If the machine is not equipped with a
main switch, supply disconnecting devices need to be
provided in the installation for all electrical supplies
connected to the machine, in accordance with EN
60204-1 standard, point 5.3.
IMPORTANT: Make sure the supply voltage is always
within the limits specified. When you have long distan-
ces in the electrical installation, it may be necessary to
use bigger cables to reduce the voltage drop.
Models outside of North America:
IMPORTANT: When the machine is connected near a
large capacity power supply transformer (500kVA or
more, wiring length shorter than 32.81 ft [10 m]) or
there is a power capacitor switch-over, a power supply
improving reactor must be installed. If you do not in-
stall this, the inverter may get damaged. Contact your
distributor for more information.
Models outside of North America: For electrical protection, if re-
quired by local regulations, there must be installed a residual cur-
rent device (RCD) and a circuit breaker in the electrical installa-
tion of the building (laundry switchboard). Refer to
Electrical connections are made at the rear of the machine. The
machine must be connected to the proper electrical supply shown
on the serial plate on the rear of the machine, using copper con-
ductors only.
