• 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 assembly is designed exclusively for use in liquid media.

The manually operated Cleanfit CPA450 retractable assembly is designed for the installation of pH, ORP and oxygen sensors in vessels and pipelines.

4.1.2 Mounting instructions

Suitable sensors

The following sensors are suitable for installation in the assembly:

• Digital sensors with Memosens technology, length 120 mm (4.72")

• pH/ORP glass electrodes, length 120 mm (4.72")

• ISFET sensors: Only the ISFET sensors specified in the "Accessories" section can be installed.

• Oxygen sensors, length 120 mm (4.72")

Orientation

The permitted orientation of the assembly depends on the sensor used:

• Digital sensors with Memosens technology, pH/ORP glass electrodes: Install the assembly at an angle of at least 15° to the horizontal →  2,  12.

• ISFET sensors: For ISFET sensors, there are basically no restrictions regarding orientation. The installation angle should be from 0 to 180°.

• All other sensors: Pay attention to the information in the relevant TI.

 2 Orientations

A Glass sensors: 15 ° to the horizontal B ISFET sensors: 0 to 180° recommended

Insert the immersion assembly into the vessel or pipe to a depth that will ensure that medium continuously washes around the electrode, even at the minimum level.

Installing with a ball valve

To replace the sensor without interrupting the process, a ball valve is required. Depending on the version, the ball valve forms part of the assembly or must be installed by the customer.

CAUTION

There is a risk of injury if used without a ball valve. due to the risk of medium escaping.

If used without a ball valve, the process must be stopped prior to dismantling the

‣

immersion tube or replacing the sensor.

 3 Measuring mode (ball valve is open):

assembly is retracted

 4 Service position (ball valve is closed): assembly is

extended for electrode replacement, calibration, rinsing

A Top edge of adapter

Depending on the assembly version, a mounting clearance of at least 700 or 1150 mm (27.6" or 45.3") is required from the top edge of the adapter.
