3.4 Installation order
To install the device in the correct way, follow the order of the following sections and their
instructions.
3.4.1 Placing the desiccant pouch and the humidity indicator
Execute the following steps to insert or replace the desiccant pouch and the humidity indicator
(Humonitor
® card) or to inspect the seal:
• Move the lock ring counterclockwise and pull out the ultrasonic cuvette with flow-through
holder (detailed information on page 21).
• Unscrew the four corner thumbscrews of the electronic device manually according to 1 in the
following drawing (if the screws are too tight, use a screwdriver for slotted grub screws).
• Remove the upper half of the electronic device 2.
• Prior to installing the desiccant pouch for the first time, remove the shipping support (plastic
tube with a red flag reaching outside) within the upper part of the device; after removing you
can discard the tube.
CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately
trained personnel. The regional occupational health and safety directives must always be
observed.
CAUTION!
A missing or saturated desiccant pouch affects not only the performance of the whole device, but
can also destroy the internal electronics!
If the seal at the device base does not fit properly or is defective, the lifetime of the desiccant
decreases. Therefore assure the following items:
• Do not start-up the device with a desiccant pouch missing, replace a saturated pouch!
• Replace the desiccant pouch when the display shows the message "DESC".
• Inspect the enclosure seal each time you replace the desiccant.
• If the seal is not properly seated or damaged, reseat or replace it!

The desiccant degrades prematurely after removing the protective packaging. Therefore do not
open the packaging before usage, install the desiccant pouch quickly and close the device as
soon as possible.
