Cleanfit CPA871 Basic safety instructions
Endress+Hauser 5
2 Basic safety instructions
2.1 Requirements for the 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 must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
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 Cleanfit CPA871 retractable assembly, which can be manually or pneumatically
operated, is designed for the installation of sensors in vessels and pipes.
Thanks to its design, it can be operated in pressurized systems (→  59).
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.
2.2.1 Use in explosion-proof areas
As a manufacturer of products used for analysis, we declare that the product supplied has
undergone an ignition risk assessment and may be used in hazardous atmospheres once
the following conditions for safe usage have been met:
• The protective ring is labeled as follows: "CAUTION, DANGER DUE TO ELECTROSTATIC
CHARGES, CLEAN USING ONLY AN ANTISTATIC CLOTH". This instruction must be
observed.
• Assemblies comprising wetted parts made of non-conductive material, must not be used
in potentially explosive atmospheres.
• The compressed air supply, sensors and limit position switches must comply with the
applicable guidelines and standards for use in hazardous atmospheres, be labeled with
the degree of protection and meet the requirements of the relevant range of application.
The ambient temperatures must be observed. The limit position switch used in the
product complies with this requirement.
• Ensure that the compressed air does not contain a potentially explosive atmosphere.
• Care must be taken to ensure that movements during insertion and retraction of the
sensor do not damage the connection.
• The product must be incorporated into the local potential equalization system.
• The Operating Instructions for the product and in particular the conditions for safe usage
must be read, understood and implemented.
The product does not need to be labeled with the degree of protection.
2.3 Occupational safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations

Basic safety instructions Cleanfit CPA871

2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.
During operation:
‣If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2.5 Product safety
2.5.1 State of the art
The product is designed to meet state-of-the-art safety requirements, has been tested, and
left the factory in a condition in which it is safe to operate. The relevant regulations and
European standards have been observed.

Installation recommendation
The two O-rings of the process seal close off the process in the relevant limit position. The
assembly is open to the process during insertion/retraction; the rinse connections must
either be pipe-fitted or sealed.
The connection between the service chamber and the process is open during
movement; the sealing water function can be used as a result. The rinse chamber
outlet must be blocked (e.g., with a shutoff valve) to implement the sealing water
function.

Installing/removing the assembly from the process
LWARNING
Risk of injury from high pressure, high temperature or chemical hazards if process
medium escapes.
‣Wear protective gloves, protective goggles and protective clothing.
‣Mount the assembly only if vessels or pipes are empty and unpressurized.
Prior to installation, check the flange seal between the flanges.
1. Move the assembly to the service position.
 (The triangle position marking is visible (→  14).
2. Secure the assembly on the tank or piping via the process connection.
3. Follow the instructions in the next section to connect pipes for compressed air and
rinse water (for the relevant assembly version).
