10.1 safety instructions

Danger

risk of injury due to electrical voltage.

▶

Before carrying out work on the system or the device, disconnect the electrical power for all the conductors
and isolate it.

▶

If the device is installed either in a wet environment or outdoors, all the electrical voltages must be of max.
35 V DC.

▶

All equipment connected to the device must be double insulated with respect to the mains according to the
standard UL/EN 61010-1.

▶

Observe all applicable accident protection and safety regulations for electrical equipment.

risk of injury due to pressure in the installation.

▶

Before any intervention in the installation, stop the circulation of fluid, cut off the pressure and drain the pipe.

▶

Before any intervention in the installation, make sure there is no pressure in the pipe.

risk of burns due to high fluid temperatures.

▶

Use safety gloves to handle the device.

▶

Before opening the pipe, stop the circulation of fluid and drain the pipe.

▶

Before opening the pipe, make sure the pipe is completely empty.

risk of injury due to the nature of the fluid.

▶

Respect the prevailing regulations on accident prevention and safety relating to the use of dangerous fluids.

Warning

risk of injury due to non-conforming maintenance.

▶

Maintenance must only be carried out by qualified and skilled staff with the appropriate tools.

▶

Ensure that the restart of the installation is controlled after any interventions.

10.2 cleaning the device

• Activate the HOLD function (see chpt. 9.12.1) in the Calibration menu in order not to interrupt the

process during cleaning.

• Always use a cleaning product compatible with the materials from which the device is made.

→

Clean device with a cloth dampened with water or a detergent compatible with the materials the device is
made of.

Please feel free to contact your Bürkert supplier for any additional information.
