GENERAL DESCRIPTION
The L2-LC Ozone Analyzer is an ultraviolet (UV) absorption analyzer designed for the monitoring of low
concentrations of ozone in the gaseous phase. If so equipped, the analyzer also allows the user to monitor
the pressure and temperature of the ozone in the measurement cell.
MECHANICAL INSTALLATION
The L2-LC can be housed for bench top, 19" rack and wall mounting. Figure 1 and Figure 2 provide
mechanical dimensions for bench top and for 19" rack mounting.. The instrument should be used in areas
where the operating conditions are within the envelope defined under General Specifications, and where
free air circulation is provided for convection cooling.
Note: If the analyzer is rack mounted, it should either have side rails or be supported in the back to
reduce stress on the front panel. The front panel mounting “ears” are not robust enough to support the
weight of the unit.
Figure 3 provides mechanical dimensions for the NEMA 4X enclosure.

SAMPLE GAS CONNECTIONS
For the units house in Bench Top and in 19" Rack configuration, there are 3 pneumatic ports located on the
rear panel. Only the ports labeled MAIN and EXH are used. . The MAIN is used as the ozone sample
input to the analyzer and the EXH is the exhaust port which discharges safe levels of ozone may be left
alone or routed to a main facility exhaust line.
Connect the MAIN pneumatic port to the sampling point using ¼" OD Teflon tubing. Be sure that the
sampling point is in a location that only the gas sample is taken into the tubing and not any liquid or
particulate matter. It is highly recommended the sample line be filtered using one of the filters provided by
IN USA.
In the NEMA 4X version, there are 2 ports identified as INPUT and OUTLET. Their fucntion is iidentical
to MAIN and EXH above.
. CAUTION: USE ONLY MATERIALS SUITABLE FOR OZONE SERVICE. CONSULT
WITH IN USA, INC. FOR ADVICE ON MATERIALS.
CAUTION: EXPOSURE TO OZONE IS HAZARDOUS. ENSURE THAT ALL GAS
CONNECTIONS ARE TIGHT AND THAT NO LEAKS EXIST.
SETTING THE SAMPLE FLOW RATE
The sample flow rate is adjustable via the valved flow meter on the front panel.. The Flow rate should be
checked periodically.
The standard version of the L2-LC is equipped with a pump. The pump must be on for the unit to operate
correctly and detect ozone.
The recommended gas flow rate is
Gas Phase Measurement : 1.0 liters/min
Dissolved Ozone in Water Measurement: 1.0 liters/min

Figure 8 illustrates the location of the ports in the NEMA version of the unit. Note that there are 2 (two) electrical
entry ports, identified as "FIELD WIRING " and "MAIN POWER" intended for allowing electrical conductors to
penetrate the enclosure, typically through a conduit, and effectuate the connections. There are also 2 (two)
pneumatic ports, identified as "INLET" and "OUTLET" which are use to bring the sample gas in and the exhaust of
the analyzer out respectively.

PREPARATION FOR OPERATION
The L2-LC Ozone Analyzer, as shipped, is configured for 100/115 VAC operation or, if requested, 220/240
VAC, and has been tested as such. However, before using the equipment, certain precautionary checks
should be made to ensure that the instrument is set up properly for the particular application in question.
AC Input Voltage Selection
Select the input voltage planned for your installation, either 100/115 VAC or 220/240 VAC. The voltage
selector is located in the power receptacle in the rear panel. See the Power Connections section.
For NEMA 4X enclosed units, the Operating voltage is 110/115 VAC unless ordered in a different
configuration.
Initial Set Up
If possible, locate the L2-LC in a clean area where free convection of air is possible. Make any connections
to external recording or monitoring equipment as necessary at the field wiring terminal block or at the RS-
232 output connector . Connect the desired sample point to the MAIN gas port using clean Teflon tubing,
keeping the sample line as short as possible. It is highly recommended to use the Teflon element filter
(supplied by IN USA) to remove particulate matter from the gas sample.
Turning the Unit On and Warming Up
Turn the instrument on by actuating the Power switch located in the rear panel. There is no Power Switch in
the NEMA 4X housed units. After a few seconds, the readout displays "Warming Up." Press the D key in
the keyboard; the ozone concentration value is then displayed. The warm-up period is necessary to allow
the UV lamp to reach stable temperature and output. Once the UV lamp has reached stability, the
"Warming Up" message is extinguished and the readout stabilized. This warming up period lasts about 5
minutes. However, if the monitor has been shut off for longer than 1 hour, allow a minimum of 3 hours for
the monitor to warm up.
The L2-LC contains a very sensitive photometer. It should be warmed up a minimum of 3 hours from a
cold start. For first time startup, an overnight warm-up period is recommended to allow complete purging
of the system and associated tubing.
While the "Warming Up" message is on, the 3 relays associated with the two programmable alarms and the
instrument error are disabled (to prevent misinterpretation by any peripherals connected to the relay
contacts). In addition, the front panel display and analog output will be read 0.00 PPM during the warm up
period. The system should be operational and displaying correct ozone readings after the warm up period.
Note: For maximum performance, it is recommended that the L2-LC monitor stays on at all times.
