CAUTION ON SAFETY
First of all, read this “Caution on safety” carefully, and then use the particle counter
in the correct way.
The following items are important for safe operation and must be fully observed. These safety precautions
are ranked in 2 levels; “DANGER” and “CAUTION.”
If operation is incorrect, a dangerous situation may occur, resulting in death
or serious injury.
If operation is incorrect, a dangerous situation may occur, resulting in minor
to medium injuries or only physical damage to equipment.
Caution on installation and transportation
(1) When the analyzer (receiver unit and transmitter unit) is installed on in-
cineration facility, make sure the facility has stopped completely.
Installing in an operating facility may cause high temperature gas injec-
tion resulting in burn.
(2) This analyzer is not explosion-proof. Do not use it in an atmosphere of
explosive gas. This may result in serious accidents such as explosion,
fire, etc.
(1) The analyzer should be installed in a place conforming with the installa-
tion requirements noted in this instruction manual, and where the weight
of the analyzer can be endured. Otherwise, it may cause a tip-over, drop,
electric shocks, fire or malfunction of the unit.
(2) Ask professional services or your dealer for installation, transportation,
reinstallation, and associated piping and wiring work. Improper installa-
tion may result in a falling accident, electric shock, or injury.
(3) Check the installation site once every 6 months to make sure that the in-
stallation surface is free of rattling. If the instrument is used under inse-
cure installation conditions, a falling accident may occur.
(4) During installation, make sure that the inside of the unit is free from ca-
ble chips and other foreign objects. Otherwise, it may cause fire, failure
or malfunction.
(5) For lifting the gas analyzer, be sure to wear protective gloves. Bare hands
may leave you prone to injury. If the temperature in the installation site is
high, it is imperative to wear leather gloves to prevent burn.

forming class D grounding work. Otherwise electric shock or malfunc-
tion may result.
(2) If the power supply voltage exceeds the rating, electric shock or damage
to the instrument may result. Be sure to use the instrument within the
specified rating range.
(3) Be sure to turn off the power before performing wiring work.
(4) Be sure to use a 600V-IV ground wire 2 mm or larger in diameter with
sufficient dielectric strength.
(5) Select input/output wires of materials and diameter that satisfy the rating
of each device. If a wire which cannot endure the rating is used, electric
shock or fire may occur.
(6) Fasten the input/output wires to the floor or wall, and use a wire protec-
tion device.
Caution on operation and use
(1) When handling the standard gas such as calibration gas, read the instruc-
tion manual of the standard gas carefully, and use the gas correctly.
(2) When toxic fumes, corrosive gas or inert gas is used as calibration gas,
be sure that the position of the air ventilation or exhaust port is suitable.
Otherwise you may inhale exhaust gas. Furthermore, suffocation, brain
disorder, circulatory deficit, or contraction of the breathing system may
occur, resulting in death.
(1) Do not touch the switch with a wet hand. Otherwise it may cause electric
shock.
(2) Do not operate the laser gas analyzer for a long time with its door left
open. Otherwise, dust, foreign matter, etc. may stick on internal walls,
thereby causing faults.
(3) Do not touch the unit terminal block during operation. Otherwise, it may
cause electric shock or injury.
(4) Before leaving unused for a long time or restarting after left at such a
status for an extended length of time, follow the directions of each in-
struction manual because they are different from normal starting or
shutdown. Otherwise, adequate performance will not be provided. Fur-
thermore, an accident or fault may be caused.
(5) Do not allow water to go into the gas analyzer. Otherwise, electric shock
or fire in the instrument may be caused.

1. GENERAL
1.1 General
Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration, NH3
density of denitration equipment and heat treat furnace, and O2, CO, and CO2density for combustion control
within a short response time. The cross-stack configuration eliminates the need for transfer of the preparation
measurement gas to the analyzer for proper measurement.
Dust resistant construction enables installation upstream of bug filter units and the application for which in-
jection volume of calcium hydroxide is controlled while measuring HCl concentration.
The analyzer adopts near-infrared laser as light source. The measuring object of the analyzer is only one
spectrum line from large numbers of absorption spectrum lines, and it measures concentration by controlling
temperature and power current. Since the range of wavelengths to be measured is a few nano meters, the an-
alyzer has minimum interference by other crossovers.
For the concentration detection, the modulated intensity of signal amplitude is employed instead of the
amount of change of light.
1.2 Handling of product and operating precautions
First read this instruction manual carefully, and then make a plan for periodic inspection to perform appro-
priate maintenance management. To maintain the long-term performance of the cross-stack laser gas analyzer
(ZSS), our periodic inspection contract is recommended.
This analyzer uses the invisible infrared laser (excluding O2). Do not watch the laser beam directly (with an
optical measuring device included) or scattering light.

4. MOUNTING METHOD
This analyzer is not explosion-proof. Do not use it in an atmosphere of ex-
plosive gas. Otherwise, it can result in serious accidents such as explosion,
fire, etc.
The analyzer should be installed in a place conforming with the installa-
tion requirements noted in this instruction manual. Otherwise, it may
cause toppling, dropping, electric shocks, fire or malfunction of the unit.
Request assistance from the professionals or the vendors when mount-
ing, moving, re-mounting and carrying out piping and wiring works as-
sociated with these activities. A poor installation may cause accidental
tip over, electric shock, injury, etc.
During installation, make sure that the inside of the unit is free from ca-
ble chips and other foreign objects. Otherwise, it may cause fire accident
or malfunction.
For lifting the analyzer, be sure to wear protective gloves. Bare hands
may leave you prone to an injury. If the temperature in the installation
location is high, be sure to wear leather gloves. Otherwise, you may suf-
fer a burn.
The analyzer is heavy. It should be transported carefully by two or more
persons if manually required. Otherwise, bodily harm may ensue.
Do not look into the transmitter unit or direct the laser beam to the eyes
of people while the power is turned ON. Otherwise, the laser beam may
damage cornea of the eye.
The laser beam is the invisible infrared light. Do not watch the laser
beam directly or scattering light.
Do not watch the laser beam directly with the optical measuring device.
Otherwise, it may cause serious damage to your eyes.

4.1 Installation conditions
4.1.1 Installation conditions of receiver unit and transmitter unit
Select a location that meets the following conditions.
(1) Ambient temperature : A place where the temperature is within -20 to 55°C and there is no
sudden temperature change.
(2) Ambient humidity : A place where the humidity is 90% RH or lower not subjected to
condensation.
(3) Measured gas temperature : Refer to “1-1 (4) Measurable component and range” in APPENDIX
1. A place where the stack is not distorted or laser light axis is not
deflected by sudden temperature change.
(4) Measured gas pressure : ±10kPa
(5) Measured gas moisture : 50vol% or less (no condensation)
(6) Measured gas velocity : 25m/s or less (However, consultation is necessary for the environ-
ment where dust (1g/Nm3or more) or water (25vol% or more) ex-
ists.) (Prevention of dust deposition or dew condensation due to in-
crease in air purge flow rate is required)
(7) Dust : 5 to 15 g/Nm3or less (depending on the installation environment
conditions such as measurable components, device specification, op-
tical light path, particle diameter, and so on)
(8) Companion flange : Prepare the flange diameter selected by the ninth digit of the code
symbols. Also, when the purchase specification is provided, prepare
the flange diameter described in the specification.
(9) Air purge : Prepare the instrumentation air containing no oil or water. (Pressure:
0.5 to 0.7 MPa or more) If there is a possibility of containing oil or
water, install an oil filter or a mist filter. When the instrumentation
air cannot be supplied, install a compressor. Prepare N2for O2ana-
lyzer and CO+O2analyzer excluding for air purge version (of which
4th digit of code symbol is T or V).
(10) Air purge flow rate : 20L/min or more (depending on measured gas temperature, velocity,
pressure, moisture or dust) (One-side air purge flow rate (L/min) ≥
Gas velocity (m/s) × 10)
(11) Path lengths (diameter) : 0.5 to 10 m (0.5 to 5 m for CO+O2analyzer)
(12) Vibration : 0.5G or less (0.2G or less for frequency 20 to 40Hz)
(When the measured optical path length is 1m or less)
(13) A place with less corrosive gases
(14) A place accessible for maintenance and check
(Refer to “4.2 Mounting dimensions of receiver unit and transmitter unit”.)
(15) A place with less electrically induced disturbances such as high electric currents or sparks in the sur-
rounding.
(16) Light axis fluctuation range: Within 0.3°C (When a unit has dust measuring function and the path
length is 0.5m).
Note) When there is a possibility of deflecting the laser light axis or reducing the light quantity due to the
large vibration acceleration, contact the manufacturer before installation.
Note) When “Box Temperature Warning” is occurred under the influence of gas temperature, mount the
reducer to keep the receiver box and the transmitter box away from the stack.
Note) When you measure the high temperature gas of 500°C or more, install a pressure sensor at the place
where the air is purged to monitor. Measuring the high temperature gas without air purge may
cause damage to the analyzer.
Note) If you install the analyzer which air purge has not been performed, problems such as permanent
glass contamination and dust contamination are caused, and it may result in improper operation of
the analyzer. Regardless of whether or not the analyzer is operated, perform air purge before instal-
lation.
