S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 19 4­4. How to start the gas monitor S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 20 CAUTION After start‐up, perform air calibration before performing gas detection (air calibration mode). NOTE • A sensor abnormality alarm is issued before the detection mode is entered if there is any abnormality in the sensor. Promptly contact Control Equipment . Gases cannot be detected if there is any abnormality in the sensor. • If there is an abnormality in the built‐in clock, a fault alarm FAIL CLOCK may be issued. Press the RESET button. The fault alarm is temporarily reset, and measurement is started with incorrect clock time. • When the power is turned on in a low‐temperature environment, the pump may produce bigger operating sound for warm‐up (about 30 seconds). This is not abnormal. S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 21 4­5. How to detect In the detection mode, put the sampling probe close to the detection area and take the reading on the display. DANGER • Toxic or other gases may blow out from the gas exhausting outlet. Never inhale the air or gases. WARNING • The gas monitor is designed to draw gases around it under the atmospheric pressure. If excessive pressure is applied to the gas inlet and outlet (GAS IN, GAS OUT) of the gas monitor, detected gases may be leaked from its inside, thus leading to dangers. Be sure that excessive pressure is not applied to the gas monitor while used. • Do not connect the sampling hose directly to a location with a pressure higher than the atmospheric pressure. The internal piping system may be damaged. • When the fresh air adjustment is performed in the atmosphere, check the atmosphere for freshness before beginning the adjustment. If other gases exist, the adjustment cannot be performed properly, thus leading to dangers when the gas leaks. • Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on your judgment. • Before use, check that there remains sufficient battery power. When the gas monitor is used for the first time or is not used for a long period, the batteries may be exhausted. Either replace the batteries with new ones or fully charge them before use. • If a low battery alarm occurs, gas detection cannot be conducted. If the alarm occurs during use, turn off the power and promptly replace the batteries with new ones or charge them in a non‐
hazardous area. • Do not block the buzzer sound opening. No alarm sound can be heard S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 22 CAUTION • Before performing gas detection, attach the sampling probe provided with the gas monitor to prevent disturbances by air dust. • Use the gas monitor with the LCD display facing upward. The gas monitor, when used with the • LCD display in a tilted or flat status, may not display correct values. • If a high‐concentration gas or highly adsorptive gas, such as HCI and NH3, is drawn, some gas may remain in the hose due to adsorption in the sampling probe or others. After drawing a high‐
concentration gas or highly adsorptive gas, clean the gas monitor to remove the adsorbed gas (draw fresh air and check that the reading becomes zero). Performing fresh air adjustment before cleaning it completely will result in inaccurate adjustment, giving adverse influence on measurement. NOTE • In a low‐temperature environment, the operating time is shortened due to the battery performance property. • At a low temperature, the response of the LCD display may get slow down. S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 23 <Manual Memory> Any instantaneous value during measurement can be recorded. Up to 256 points of data can be recorded.

Gas calibration method Perform span adjustment of sensors using a calibration gas at least once every six months. The span adjustment requires dedicated equipment and a calibration gas. Request Control Equipment for it. If you perform the span adjustment for yourself, prepare these tools in advance and perform the adjustment in accordance with the "Maintenance Manual." 6­3. How to clean Clean the gas monitor if it becomes extremely dirty. The gas monitor must be turned off while cleaning it. Use a waste cloth to remove dust. Do not use water or organic solvent for cleaning because they may cause malfunctions. Because an extremely large amount of dust inside the sampling probe may disturb the gas detection, it must be cleaned with dry AIR, etc. CAUTION When cleaning the gas monitor, do not splash water over it or use organic solvents such as alcohol and benzene on it. The surface of the gas monitor may be discolored or damaged. NOTE When the gas monitor gets wet, water may remain in the buzzer sound opening or clearances. Drain water as follows: 1. Wipe away moisture on the gas monitor thoroughly using a dry towel, cloth, etc. 2. While holding the gas monitor firmly, shake it about ten times with the buzzer sound opening facing downward. 3. Wipe away moisture coming out from the inside thoroughly using a towel, cloth, etc. 4. Place the gas monitor on a dry towel, cloth, etc. and let it stand at normal temperatures.

Parts replacement <Replacement of Consumables> Sensor Replacement The built‐in sensors of the gas monitor have a validity period and must be replaced regularly (within two years). The sensor life has expired if, for example, the sensors cannot be calibrated in span adjustment, the readings do not come back after fresh air adjustment, or the readings fluctuate. Contact Control Equipment . The warranty period is one year for all the sensors. Dust Filter Replacement Procedure Because the dust filter may gradually get dirty or clogged over the time, it must be replaced regarding the operating conditions. Check the dust filter, and then replace it as necessary. The gas monitor has various built‐in filters. Sampling probe The sampling probe has a built‐in Teflon filter. Replace the filter when it has absorbed water, has a low flow rate, or looks significantly contaminated. S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 40 CAUTION If the knob is not completely tightened, accurate gas measurement may not be possible due to leaks, or water may get inside. The same thing occurs if a minute foreign substance is caught beneath the knob. <Replacement of Regular Replacement Parts> List of recommended regular replacement parts No. Item Maintenance intervals Replacement intervals 1 2 3 Rubber seal Tube Pump unit (RP‐

Procedures to store the gas monitor or leave it for a long time The gas monitor must be stored under the following environmental conditions. • In a dark place under the normal temperature and humidity away from direct sunlight • In a place where gases, solvents or vapors are not present Store the gas monitor in a shipping carton, if any, in which the product was delivered. Store the gas monitor away from dust, etc. if the shipping carton is not available. Make sure to store the gas monitor with the display facing upward. CAUTION • If the gas monitor is not used for a long time, turn on the power at least once every six months and check that the pump draws in air (about three minutes). The gas monitor, when not activated for a long time, may cease to work because of hardening of the grease in the pump motor. • Store the gas monitor with dry batteries attached. While the power of the gas monitor is OFF, the sensor is energized at all times. If dry batteries are removed, the sensor may not function at the next use of the gas monitor. Therefore, it is necessary to store the gas monitor with the batteries in it. NOTE • Check that the battery level is sufficient once every six months. If a low battery voltage alarm is triggered while checking, replace the dry batteries with new ones (or charge the Li‐ion battery unit). Because the sensor is energized at all times even when the power is OFF, it is necessary to replace the batteries (or charge the Li‐ion battery unit). • If the gas monitor is used with low‐level batteries, battery leaks resulting from over discharging may occur. • If the gas monitor with a Li‐ion battery unit is not used for a long time, it is recommended to store it after discharging the batteries until the battery level icon shows one battery mark or so. If the gas monitor is stored with the batteries fully charged, the batteries get deteriorated more quickly and may have shorter life S C ‐ 8 0 0 0 – O P E R A T O R S M A N U A L P a g e | 43 7­2. Procedures to use the gas monitor again CAUTION When you use a stopped/stored gas monitor again, do not forget to perform a gas calibration. For information on readjustment including gas calibration, please contact Control Equipment . 7­3. Disposal of products When the gas monitor is disposed of, it must be treated properly as an industrial waste in accordance with the local regulations. WARNING • Do not disassemble the electrochemical type sensor because it contains electrolyte. Electrolyte may cause severe skin burns if it contacts skin, while it may cause blindness if it contacts eyes. If electrolyte is adhered on your clothes, that part on your clothes is discolored or its material is decomposed. If contact occurs, rinse the area immediately with a large quantity of water. • Dispose of the batteries in accordance with procedure specified by the local authority.
