Installation
Mounting the System
Mounting the hygrometer system consists of mounting the electronics
unit, the probes, and the sample system(s).
Mounting the Electronics
Unit
Use the outline and dimension drawings at the end of this chapter to
mount the Series 1. These drawings provide clearance and other
mounting dimensions needed to prepare the site for mounting.
IMPORTANT:
To comply with the Low Voltage Directive, you must
install a switch or circuit breaker on the input power
line. For greatest safety, locate the circuit breaker or
power switch near the electronics console.
Be sure to follow the guidelines outlined in Choosing a Site on
page 1-4 before mounting the enclosure.
Note:
You may want to make probe, Delta F Oxygen Cell, recorder,
and alarm connections before mounting the enclosure if the
installation location does not provide enough room for these
connections to be made easily after installation.
Mounting the Sample
System
The sample system is normally fastened to a metal plate that has four
mounting holes. GE Panametrics also provides the sample system in
an enclosure if requested. In either case, fasten the sample system
plate or enclosure with four bolts–one in each corner. If you ordered
sample system outline and dimension drawings, they will be included
in your shipment.
Connect the sample system inlet and outlet to the process and return
using the appropriate fittings or an appropriate NPT adapter.
Caution!
Do not start a flow through the system until all probes
and transmitters are properly installed.
Mounting the Oxygen
Cell Assembly
If your oxygen cell is not mounted into a sample system, refer to
Figure 1-27 on page 1-40 for dimensions to mount the cell.
