6.3.2 Installing the Membrane
To install the new membrane, follow the steps below:
Unscrew the protection cap, using the tool provided in the
maintenance kit.
CAUTION:
Never remove the protection cap, unless you plan to
replace the membrane.
Pull up the membrane holding ring with the tool provided
in the maintenance kit.
Remove the old membrane and discard it.
Note:
The membrane mounting surface must be clean and
even (on top of the sensor, where the membrane and
sensor have contact).
Replace the membrane O-ring on the sensor head with a
new one.
Note:
The 29039.0 Nitril O-ring can be reused if it is still in good
condition. Membrane O-rings are part of the protection
cap kit.
In the maintenance kit, pick up the two part membrane
mounting tool.
Install the sleeve over the sensor head (end with shoulder
downwards).
Note:
Once installed, a membrane cannot be reused. Avoid
touching the membrane with bare fingers, as this may
affect its sensitivity.
