4.2 Mounting the measuring device
4.2.1 Wall mounting
The device is designed for wall mounting. If wall mounting is not practicable, the device
can be mounted on any suitable level surface.
• Ensure that the temperature does not exceed the maximum permitted operating
temperature range (0 to 50 °C (32 to 122 °F)).
• Leave approx. 20 cm (8 inch) of free space above the device to ensure that there is
sufficient room for calibration and cuvette maintenance.(→  2)
• Mount the device as close as possible to the sampling point to ensure fast response times
(within 2 to 3 m (6 to 10 ft)).
1. Drill mounting holes for the M4 mounting screws to install the field terminal box.
2. Drill mounting holes for the M6 mounting screws to install the device housing on top
of the terminal box.
3. Mount the terminal box.
4. Mount the rest of the device on top of the terminal box.
4.2.2 Installing the desiccant pouch
The device is equipped with a continuous vapor purge system. A replaceable desiccant
pouch in the lower portion of the instrument dries the air. System heat is used to warm the

5 Base of housing
1. Unscrew the four corner screws (item 1).
2. Remove the electronic component of the device (item 2).
3. Open the bag protecting the desiccant pouch (item 4), and place the pouch with the
humidity indicator (item 3) in the base of the housing (item 5).
Ensure that you install the desiccant pouch immediately after opening the bag to
prevent premature degradation of the desiccant.
4. Return the electronic component of the device to its original position.
5. Tighten the four corner screws.
To prevent premature saturation of the desiccant, it is recommended that you keep
the measurement chamber covered at all times.
4.2.3 Plumbing the measuring device
• The device requires only a very low overpressure in the flow assembly to operate,
approx. 0.069 bar (1 psi).
• The flow controller is rated for a maximum overpressure of 13.8 bar (200 psi).
• The minimum flow rate for the flow-through cuvette is 100 ml/min to 1 l/min
(0.026 to 0.26 US gal/min).
• The maximum permitted medium temperature is 50 °C (122 °F).
