MOTOR PROTECTION DEVICES
Each motor is protected against short-
circuits and current overload by automatic
magneto-thermal relays.
Lamp
"M"
switching on signalizes the
intervention of any of these relays
.
In this case, the machine should be
switched off and qualified personnel
should be asked for repair.
ELEMENTS PROTECTION
Each element is protected against short
circuit by automatic breakers.
Tank elements are protected against dry
running by minimum level pressure switch.
Boiler and dryer elements by thermostats
with manual reset.
In case of troubles, ask for the intervention
of qualified and authorized personnel (see
paragraph “Instructions for the installer”).
FLOWMETER
This device checks that the water flow is
enough for a good final rinse. A red flash
light
“T”
alarms if water pressure is too
low.
RESIDUAL RISKS
Although the appliance is equipped with
the above-mentioned safety devices,
danger of burns to upper limbs persists.
As already mentioned in the paragraph
“DURING WASHING OPERATIONS”,
avoid dipping your naked hands into soapy
hot water of the tanks. This can cause
burns and skin irritations.
In this case, immediately rinse them with
plenty of water.
Risk of crushing the upper limbs
As already said the conveyor plant is
provided with a mechanical clutch torque
limiter whose calibration depends upon the
mechanical strength necessary to transport
the tableware.
Thanks to the presence of protection
devices and to the segretation of
dangerous moving parts, the risk of
crushing the upper limbs has been
removed. However never introduce your
arms into the washing tunnel when the
machine is running.
