2 Basic safety instructions

2.1 Requirements for personnel

• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions and

personnel.
Repairs not described in the Operating Instructions provided must be carried out only directly at the manufacturer's site or by the service organization.

2.2 Designated use

The manually operated Cleanfit COA451 retractable assembly is designed for the installation of oxygen sensors in vessels and pipelines. Their mechanical construction means that they can be operated in pressurized systems (see technical data).
The assembly is designed exclusively for use in liquid media. Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted. The manufacturer is not liable for damage caused by improper or non-designated use.

2.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
Electromagnetic compatibility
• The product has been tested for electromagnetic compatibility in accordance with the
applicable international standards for industrial applications.
• The electromagnetic compatibility indicated applies only to a product that has been
connected in accordance with these Operating Instructions.
Basic safety instructions Cleanfit COA451

2.4 Operational safety

products must be taken out of service and protected against unintentional operation.
CAUTION
L
Cleaning not switched off during calibration or maintenance activities
Risk of injury due to medium or cleaning agent!
If a cleaning system is connected, switch it off before removing a sensor from the medium.
‣
