4 Installation
4.1 Installation conditions
Instructions for installing in pressurized systems
General
‣Only the pressure-resistant versions – CPY7B-B or CPY7B-C – should be operated in
pressurized systems.
‣Never exceed the maximum permitted pressure of 11 bar (160 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.

5.2 Venting
Having topped up the electrolyte, you have to vent the electrolyte hose.
LCAUTION
Minor skin or eye injuries are possible as a result of contact with the electrolyte
‣Wear safety gloves and protective goggles.
1. Release the electrolyte hose connection on the sensor.
2. Press in the tappet of the hose union until there is a flow of electrolyte:
A0005761
3. Reconnect the electrolyte hose to the sensor.
5.3 Assembly
Follow the sequence for filling the vessel with electrolyte in the reverse order.
1. Fit the top part and tighten the coupling nut (finger-tight, maximum 5 Nm).
2. Close the manually operated valve.
3. Connect the hose union.
4. Open the manually operated valve.

CPY7B Maintenance
Endress+Hauser 11
6 Maintenance
Routine checks
Regularly check all couplings for leaks
‣Version CPY7B-A
Visual inspection
Version CPY7B-B, CPY7B-C
1. Cut off the compressed air supply using the manually operated valve (toggle to
horizontal position).
2. Observe the pressure gauge on the CPY7B. If the pressure has not dropped after 15
minutes, the couplings are leak-tight.
3. If the pressure has dropped, re-tighten the couplings. Check the seal to ensure it is
intact and seated correctly.
NOTICE
Prohibited lubricants
If prohibited lubricants are used, there is a risk of stress cracks forming on the polycarbonate
parts.
‣Use only the lubricants approved for the material to lubricate polycarbonate parts, such as
couplings.
‣Observe the instructions of the lubricant manufacturer.
Release vessel pressure (only versions CPY7B-B, CPY7B-C)
LCAUTION
Minor skin or eye injuries are possible as a result of splashing electrolyte
‣Only ever perform other maintenance work when the system is unpressurized.
‣If using an air pump connection:
Release the valve nipple on the cover by one rotation (AF 19).
If using a compressed air connection:
1. Cut off the compressed air supply at the manually operated valve (toggle bar in
horizontal position).
2. Remove the compressed air hose (turn hose union 1 revolution counterclockwise).
3. Release the pressure from the vessel (toggle bar of manually operated valve in vertical
position).
