Water Drop-Out Filter (Option) Maintenance
Located externally on the right side of the enclosure, the Water Drop-Out Filter
(Section 4.3.1.2) should be checked periodically for water build-up and drained. To
drain this filter:
1.
Disconnect the ozone supply line from the instrument.
2.
Shut off flow to the instrument using the needle valve on the front panel.
3.
Remove cap from the fitting located on the bottom of the filter and allow it to
drain.
4.
Replace cap and adjust flow to instrument.
9.9.
Particulate Filter Replacement
Replacement of the particulate filter, a Teflon coalescing membrane should be rarely
required. However, if it does become fouled, possibly indicated by a significant
reduction in the gas pressure measured in the O
3
cell, which would trigger a warning
in the instrument, replace it as follows:
1.
Remove the orange cap from the top of the water drop-out filter.
2.
Located the membrane on the underside of the cap assembly and replace it.
3.
Tightly secure the orange cap back onto the water drop-out filter.

Configuring the Analog Output
The analog output can be configured for either 0-5V DC or 4-20mA operation. To
change or verify the configuration of the analog output:
1.
Disconnect power from the 465L.
2.
Remove the six screws and the top cover (Rack Mount Configuration) or open
front panel (NEMA Configuration.)
3.
Locate the Mainboard PCA (see Figure 9-1 or Figure 9-2).
4.
Set the desired operation as shown in Figure 9-4.
5.
Re-Install the top cover or re-secure the front panel (NEMA Configuration.)
