A.8 Machine Cleaning And Maintenance - Nordcap Zanussi 406402315 Instrucciones De Instalación

• To protect the power supply of the machine against short circuits and/or overloads,
install a thermal fuse or a suitable automatic thermal magnetic circuit breaker, ADS
(Automatic Disconnection of Supply).
• To protect the power supply of the machine against current leakages, install a high-
sensitivity manual reset RCD (Residual Current Device), suitable for overvoltage
category III.
• For protection against indirect contacts (depending on the type of supply provided for
and connection of earths to the equipotential protection circuit
EN 60204-1 (IEC 60204-1) with the use of protection devices that ensure automatic cut-
off of the supply in case of isolation fault in the TN or TT systems or, for IT systems, the
use of isolation controllers or differential current protection devices to activate automatic
power disconnection (an isolation controller must be provided for indicating a possible
first earth fault of a live part, unless a protection device is supplied for switching off the
power in case of a such a fault. This device must activate an acoustic and/or visual
signal which must continue for the entire duration of the fault). For example: in a TT
system, a residual current device with cut-in current (e.g. 30 mA) coordinated with the
earthing system of the building where the machine is located must be installed ahead of
the supply.
• Make sure to install an emergency switch at the infeed and outfeed of the rack-type
dishwasher. For all additional modules installed later, move the emergency switch at the
ends of the equipment.
• For all the additional modules installed later, make sure that the power cable supply is
properly sized.
A.8 Machine cleaning and maintenance
• Refer to "A.3 Personal protection equipment" for suitable personal protection equipment.
• Put the machine in safe conditions before starting any maintenance operation.
Disconnect the machine from the power supply and carefully unplug the power supply
cable, if present.
• Depending on the model and type of electric connection, during maintenance operations,
the cable and plug must be kept in a visible position by the operator carrying out the work.
• Do not touch the machine with wet hands or feet or when barefoot.
• Do not remove the safety guards.
• Use a ladder with suitable protection for work on machines with high accessibility.
• Respect the requirements for the various routine and extraordinary maintenance
operations. Non compliance with the instructions can create risks for personnel.
• Extraordinary maintenance, checking and overhaul operations must only be carried out
by a specialised personnel or the Customer Care Service, provided with suitable
personal protection equipment (safety shoes and gloves), tools and ancillary means.
Ordinary maintenance
• Do not clean the machine with jets of water.
• Contact with chemical substances (e.g. detergent, rinse aid, scale remover, etc.) without
taking appropriate safety precautions (e.g. personal protection equipment) can involve
exposure to chemical risk and possible damage to health. Therefore always refer to the
safety cards and labels on the products used.
Repair and extraordinary maintenance
• Repair and extraordinary maintenance have to be carried out by specialised authorised
personnel. The manufacturer declines any liability for any failure or damage caused by
