(and for steam if applicable).
• Read the manual thoroughly before use.
• 7KHPDFKLQHVKRXOGRQO\EHKDQGOHGE\DXWKRUL]HG
personnel. Personnel must also receive regular training.
• If any part is missing or damaged - do NOT use the product.
• Exercise caution when using the machine, as it uses hot
water and possibly steam.
• Exercise caution when handling the chemical agent used in
the machine. Follow the instructions on the agent:
࢓if the agent is swallowed, comes into contact with the
eyes or skin or if vapors are inhaled.
࢓for instructions on dosage amount and washing
temperatures.
࢓for instructions regarding storage and sorting/disposal
of packing.
• Make sure that the machine has access to detergent before
the process starts. This is important both for the operation of
the machine and for keeping the washing chamber free from
staining.
• The machine must be kept clean if it is to work properly.
• Do not wash down or hose down the machine with water.
• Installation and service work must be performed by trained
personnel.
• Never bypass the machine's door switch under any
circumstances.
• Always connect the equipment via an RCD (residual current
device).
• $OZD\VXVHDJURXQGHGSRZHUVXSSO\IRUWKHÀXVKHU

4.3 Preventive maintenance
For safety purposes, never modify equipment or use incompatible
parts.
4.3.1 Periodic maintenance
Periodic maintenance and system testing must be performed
to ensure safety and the machine's proper operation.
The amount of maintenance required depends largely on the
quality of the incoming water and how often the machine is used.
The maintenance interval will have to be determined in each
individual case. Arjo recommends that the stated maintenance
operations be performed at intervals according to the service table.

4.3.2 Service table
Note!
The service table is only shown for information purposes.
WARNING!
Maintenance may only be performed by authorized
service technicians.
WARNING!
The machine is connected to the electricity supply
and some components are live.
The service table below shows recommended maintenance
intervals.
In addition to system testing, we recommend that appropriate
cleaning tests and temperature validation are performed according
to EN ISO 15883.
