3.3.1 Instrument Mechanical Installation

The 8800 Series Trace Moisture Analyzer is available in several different physical configurations.

Please follow the instructions below, which describe the instrument being installed. The sensor

installation is discussed in Section 2: Sensor and Sampling Techniques.

3.3.1.1 8800A (DIN43700) Enclosure Installation

The standard 8800A Trace Moisture Analyzer is provided with two clip-on compression panel

mounting brackets. These brackets allow the user to mount and secure the instrument onto a prop-

erly cutout panel (137mm x 67mm). Consult with drawing in appendix E, for all relevant dimen-

sions. Installation is accomplished by attaching 2 clips, one on each side of instrument, and

inserting the instrument into the panel cutout. Pressure must be applied along edges of instrument

until it is firmly seated.

The 8800A Trace Moisture Analyzer may be ordered with an environmental seal option. This

option provides a gasket (installed at the factory) to seal the face plate to the enclosure box, and a

gasket (to be installed by the user) to seal the enclosure box to the user’s mounting panel. To

achieve a good environmental seal the 8800A Trace Moisture Analyzer must be mounted onto a

rigid flat panel with a cutout according to the specified dimensions, using the provided panel gas-

ket and all four provided mounting brackets. The instructions listed below should be followed.

• If the clip-on mounting brackets are installed on the instrument enclosure, remove them.

• Make sure that the panel gasket is flat and even around the box bezel. Handle the gasket care-

fully as not to tear it.

• Insert the box into the user’s panel cutout, consult with drawing in appendix E for proper

panel cutout dimensions.

• Attach all four mounting brackets to the instrument enclosure from the rear of the panel, make

sure they are fully locked in.

• Use a screwdriver to tighten the mounting bracket screws, all four screws should be tightened

uniformly, the panel gasket should be compressed.

3.3.1.2 8800B (IP65) Enclosure Installation

The instrument can be installed as a wall or panel surface mount, by making use of four screw

holes on the back (bottom) of the instrument enclosure. Open the instrument cover for access to

these screw holes. They are located at the corners of the enclosure and outside of the NEMA seal.

Do not drill other mounting holes, as you may compromise the seal. Refer to Appendix E for all

relevant dimensions.
