Always disconnect power and water
supplies before a service technician
performs any service procedure.
Where applicable, steam and/or
compressed air supplies should also
be disconnected before service
is performed.
AC Inverter Drive
This machine is equipped with an AC
inverter drive requiring special
attention with regard to the operating
environment.
• An especially dusty or linty
environment will require more
frequent cleaning of the AC inverter
drive cooling fan filter and of the AC
inverter drive itself.
• Power line fluctuations from sources
such as uninterruptible power
supplies (UPS) can adversely
affect machines equipped with the
AC inverter drive.
• A clean power supply free from
voltage spikes and surges is
absolutely essential for machines
equipped with the AC inverter drive.
Nonlinear inconsistencies (peaks
and valleys) in the power supply can
cause the AC inverter drive to
generate nuisance errors.
If input voltage measures above
240V for a Q voltage machine, above
415V for a P voltage machine, or
above 480V for an N voltage
machine, either ask the power
company if their representative can
lower the voltage or install a step-
F232048
down transformer kit available from
the manufacturer. Voltages above
250V and 490V require additional
measures.
• Sufficient space to perform service
procedures and routine preventive
maintenance is especially important
for machines equipped with the AC
inverter drive.
Misuse
Never use this machine for any purpose
other than textile processing.
• Never wash petroleum-soaked rags
in the machine. This could result in
an explosion.
• Never wash machine parts or
automotive parts in the machine.
This could result in serious damage
to the basket.
• Never allow children to play on or
around this machine. Death or
serious injury can result if children
become trapped in the machine. Do
not leave children unattended while
the machine door is open. These
cautions apply to animals as well.
• Never use UY machines in
pressurized applications.
