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.”
DANGER
If operation is incorrect, a dangerous situation may occur, resulting in death
or serious injury.
CAUTION
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
DANGER
•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.
•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.
CAUTION
•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.
•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.
•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.
•During installation, make sure that the inside of the unit is free from cable
chips and other foreign objects. Otherwise, it may cause fire, failure or
malfunction.
•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.
•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.

Caution on Wiring
CAUTION
•Be sure to connect a ground wire securely to the specified place by per-
forming class D grounding work. Otherwise electric shock or malfunction
may result.
•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.
•Be sure to turn off the power before performing wiring work.
•Be sure to use a 600V-IV ground wire 2 mm or larger in diameter with
sufficient dielectric strength.
•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.
•Fasten the input/output wires to the floor or wall, and use a wire protec-
tion device.

Caution on operation and use
DANGER
•When handling the standard gas such as calibration gas, read the instruc-
tion manual of the standard gas carefully, and use the gas correctly.
•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. Oth-
erwise you may inhale exhaust gas. Furthermore, suffocation, brain dis-
order, circulatory deficit, or contraction of the breathing system may oc-
cur, resulting in death.
CAUTION
•Do not touch the switch with a wet hand. Otherwise it may cause electric
shock.
•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.
•Do not touch the unit terminal block during operation. Otherwise, it may
cause electric shock or injury.
•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 shut-
down. Otherwise, adequate performance will not be provided. Further-
more, an accident or fault may be caused.
•Do not allow water to go into the gas analyzer. Otherwise, electric shock
or fire in the instrument may be caused.
•Do not smoke nor use a flame near the gas analyzer. Otherwise, it may
result in a fire.
•Do not use the receiver unit or the transmitter unit as a footstool. Other-
wise, it may damage the analyzer, disable the correct measurement, and
besides, injury may result when the unit is removed.
•The product uses Class I laser.
•Do not remove the transmitter unit while the power is ON during opera-
tion. Also, do not direct the transmitter unit to people. Otherwise, laser
beam can enter eyes of people and damage its cornea.
•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.
•Be sure to purge the receiver unit and the transmitter unit. Do not use the

1. GENERAL
1.1 General
Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration and
NH3density of denitration equipment 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 ana-
lyzer 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. Do not watch the laser beam directly (with an optical measur-
ing device included) or scattering light.

4. MOUNTING METHOD
DANGER
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.
CAUTION
yThe 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.
yRequest 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.
yDuring 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.
yFor 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.
yThe analyzer is heavy. It should be transported carefully by two or more
persons if manually required. Otherwise, bodily harm may ensue.
yDo 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.
yThe laser beam is the invisible infrared light. Do not watch the laser
beam directly or scattering light.
yDo not watch the laser beam directly with the optical measuring device.
Otherwise, it may cause serious damage to your eyes.
