• Measuring point faults may be repaired only by authorized and specially trained personnel.
Repairs not described in the Operating Instructions provided may only be carried out
directly by the manufacturer or by the service organization.
2.2 Designated use
The electrolyte vessel is designed:
• To provide unpressurized or pressurized electrodes with a top-up supply of liquid electrolyte
• To create an electrolyte bridge in measuring devices with reference electrodes.
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 Occupational safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations

4 Installation
4.1 Installation conditions
Instructions for installing in pressurized systems
General
‣Only the pressure-resistant versions – CPY7-D or CPY7-E – should be operated in
pressurized systems.
‣Never exceed the maximum permitted pressure of 6 bar (87 psi) at an ambient
temperature of 30 °C (86 °F).
‣Only use the pressure hose supplied.
‣Regularly check the couplings, valves and hoses for leaks and damage.
Before installing or removing the electrolyte vessel or filling the vessel:
‣Ensure the system is unpressurized and vent the vessel where necessary.
In the event of severely fluctuating medium pressure:
‣Regulate the pressure in the electrolyte vessel in such a way that it is always above the
medium pressure.
