Section 3 Installation
Important Note: Only qualified personnel should conduct the tasks
described in this section of the manual.
3.1 Unpacking the sensor
Remove the sensor from the shipping container and inspect the
sensor for damage. Verify that all items listed in
Figure 4 are
included. If any items are missing or damaged, contact the
manufacturer or distributor.
3.2 Unpacking the sensor cartridge
Important Note: Avoid touching the membrane on the sensor
cartridge or damage to the sensor may occur.
1. Pay attention to the set in operation before date on the outside
of the sensor cartridge storage container and the certificate.
This is not the expiration date but the optimal date for putting
the cartridge into operation for maximum life of the sensor
cartridge.
2. Remove the cap of the storage container (see Figure 6 on
page 13 ).
3. Take the sensor cartridge out of the storage container and
remove the black gasket. This black gasket is not needed for
installation but is useful to create a seal for storage of the
sensor cartridge in the storage container.
Note: Make sure that the sensor cartridge is not exposed to air for
more than 30 minutes.
Important Note: Before fitting the sensor cartridge in the sensor
adapter, hold sensor cartridge in hand with membranes facing
straight down and shake gently in a downward motion two times to
remove air bubbles that may form underneath the membrane.
