Insert the finger nail below both rubber seals at the semi-circular
pocket in the diaphragm cap (the vent is positioned there) and
pull the rubber seals to the bottom until the needle top-sized vent
(see Fig. 4) becomes visible and hold the seals. When screwing
together, excess electrolyte should escape freely through the vent
(see Fig. 4) such that the diaphragm is not damaged by excess
pressure.
Position the electrode shaft vertically on the filled diaphragm cap.
Do not obstruct the vent with your fingers.
Screw the electrode shaft manually into the diaphragm cap up to
the stop such that there is no free gap between the diaphragm
cap and the electrode shaft.
Re-insert the rubber seals flush into the groove of the diaphragm
cap.

IMPORTANT
• Depressurise the system before installing the sensor in the
flow housing. Close stop valves to the front and rear of the
in-line probe housing.
• Placing/removing the sensor into/from the in-line probe
housing should be done slowly.
• Do not exceed the maximum permitted operating pressure
of 1 bar!
