2-1. Danger cases

DANGER

About use

• While conducting measurement in a manhole or confined space, do not lean over or look into the manhole or closed space. It may lead to dangers because oxygen-deficient air or other gases may blow ou t.

• Oxygen-deficient air or oth er gases may be discharg e d f rom the gas exhaustin g ou t le t of the detector. Never inhale t he air or gases.

• High-concentration (100% LEL or higher) gases may be discharged from the gas exhausting outlet of the detector. Never use fire near it.

- 6 -

2-2. Warning cases

WARNING

Sampling point pressure

• The concentration meter is designed to draw gases under the atmospheric pressure. If excessive pres sure is applied to th e g as in l et an d ou t l et of t h e de t ec t or, measure d gases may leak out from its inside and may cause dangerous conditions. Be sure that excessive pressure is not applied to th e de t ec t or’s gas inlet or ou tl e t during use.

Air calibration in atmosphere

• Perform an air calibration in a fresh air environment. If interference gases or other gases exist, the adjustmen t c an n ot be performed prop erly, thus leading to da ng er s wh e n gas is present.

Response to gas alarm

• A gas alarm is triggered by changes in temperature and humidity. In such a case, check the atmosphere for freshness and perform air calibration again in the measured atmosphere. Example) If th e de t ec t or is t ur n e d on in a ro om with a temperature of 20 ºC an d a humidity of 40% RH and taken outs id e ( a temperature of 30ºC a nd a humidity of 60% RH), an alar m is triggered by humidity changes. In such a case, perform air calibration outside and measure. The detector per f or ms air calibration a ut omatically when it is tur n e d on . E v en in s uch a case, check the atmosphere for freshness and perform air calibration again in the measured atmosphere.

WARNING

Battery level check

• Before use, check that there remains sufficient battery power . When the detector is not used for a long period, the batteries may be exhausted. Never fail to replace them with new ones before use.

• If a low battery voltage alarm is triggered, gas detection cannot be conducted. If the alarm is triggered during use, turn off the power and promptly replace the batteries in a safe area.

Others

• Do not throw the detector into fire.

• Do not wash the detector in a washing machine or ultrasonic cleaner, etc.

• Do not block the buzzer sound opening. No alarm sound can be heard.

• Do not remove the battery while the power is on.

2-3. Precautions

CAUTION

Do not use the detector where it is exposed to oil, chemicals, etc. Do not submerge the detector under water on purpose.

• Do not use in a plac e wh ere the detector is exp osed to liquids such as o il an d c h emicals.

• The detector is not water-pressure-resistant. Do not use the detector where a high water pressure is

applied to it (under a faucet, shower, etc.) or submerge it under water for a long time. The detector is water-proof only in fresh wa ter and running water, and not in hot wat er, salt wat er, detergen t, chemicals, human sweat, etc.

• The gas inlet and outlet are not water-proof. Be careful not to let water such as rainwater, etc. get into these parts. Because this may cause trouble and gas cannot be detected.

• Do not place the de tector where water or d irt gets accumulated. The detector placed at such a location may cause malfunction due to water or di rt that gets into the buzzer opening, etc.

• Note that dra win g i n d irty water, dust, metallic powder, etc. will si gn if icantly deterior at e th e s e ns or sensitivities. Be careful when t he de tector is used in an environment where thes e el ements exist.

Do not use the detector in a place where the temperature drops below -20ºC or rises over 55ºC.

• The operating temperature of the detector is -20 to +55ºC. Do not use the detector at higher temperatures, humidities and pressures or at lower temperatures than the operating range.

• Avoid long-term use of the detector in a place where it is exposed to direct sunlight.

• Do not store the detector in a sun-heated car.

• Avoid a sudden humidity or temperature change.

• Do not leave the de tector in a place with hi g h temperature and hum i di ty for a long time. The

performance of the unit m ay de t eriorate.

Observe the operating restrictions to prevent condensation inside the concentration meter or gas sampling hose.

• Condensation formed on the detector or taper nozzle causes clogging, gas adsorption, etc., which may disturb accurate gas detection. Thus, condensation must be avoided. In addition to the installati on envir onment, c areful ly monitor the temperature/humidity of the sampling point to prevent condensati on , etc. on the detector or tape r no zzl e . P l e as e observe the operatin g r estrictions.

Do not use a transceiver near the detector.

• Radio wave from a transceiver or other device near the detector may disturb readings. If a transceiver or ot h er r ad i o w a ve trans mitting device is us ed , it m us t be us e d in a pl ace w her e it disturbs nothing.

• Do not use the det ec t or near a device that em its str on g e lectromagnetic wa v es ( h ig h-frequency or high-voltage devices).

Verify that the flow check display is rotating before using the detector.

• If the flow check display is not rotating , th e g as de tector is not operati n g pr o p erly. Check whether the flow rate is lost.

Never fail to perfor m a regular maintenance.

• Since this is a precision device , a regular maintenance must be performed. Continuing to use the detector without performing maintenance will compromise the sensitivity of the sensor, thus resulting in inaccurate gas detection.

CAUTION

Others

• After a gas continuously comes into contact or a highly-concentrated gas comes into contact, the detector may stay in alarm. In such a case, draw fresh air for more than five minutes (recommended) and perform air calibration again.

• Pressing buttons unnecessarily may change the settings, preventing alarms from activating correctly. Operate the detector using only the procedures described in this operating manual.

• Do not drop or gi ve shoc k to the detector. The accuracy of th e de tector may be deter i ora te d.

• Do not jab the buzzer opening with a sharp-pointed item. Doing so may cause a failure or

damage.

• Do not remove the panel sheet on the display. The water-proof and dus t-proof performances will be deteriorated.

• Do not affix a label or the like on the infrared port. Infrared communications can no longer be conducted.

• The operating environment may include gases that have harmful effects on the sensor of the detector. The detector cannot be used in the presence of the following gases: (1) High-concentration sulfides (such as H2S, SO2, etc.)(2) Halogen gases (such as chloride compounds, etc.)(3) Silicone (Si compounds)(4) High-concentration solvent gasesDo not use the detector in th e pr esence of the above (1) , ( 2), and (3) gases (such as h ig h-concentration sulfides, halo gen gases, silicone, etc.), which may shorten the sensor life significantly or cause malfunctions such as inaccurate readings. In case the detector is used for detection in the presence of silicone, etc., be sure to check the gas sensitiv it i es before using it again. If the above (4) gas (high-concentration solvent gas) is exposed, a crack may occur in the unit. Thus, do not use high-concentration solvent gases.

About battery replacement

• Never fail to tur n off the po wer of the detector before replacing the b atteries.

• Replace both of the two batteries with new ones at one time.

• Pay attention to the polarities of the bat te r i es.

Usage

• In a low-temperature environment, the operating time is shortened due to the battery performance property.

• At low temperat ures, the responses of the LCD display may slow down.

• Perform air calibration under pressure and temperature/humidity conditions close to those in

the operating en v iro nment and in fresh air.

• Perform air calibr ation after the readi ng is stabilized.

• If there is a sudden temperature change of 15ºC or more between the storage and operational

locations, tur n on t h e p o we r of th e de tector, let it stand for more than 5 minutes in a similar environment to the operational location, and perform air calibration in fresh air before using it.

• When cleaning the de te cto r, do not splash water over it o r use o r gani c solv en ts such as alcohol and benzine on i t. The sur f ac e of th e d etector may be disco lored or damaged.

• If the detector 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 detector, when not activated for a long time, ma y ce as e to wo r k because of hardenin g of th e gr e ase in the pump motor.

• If the detector is not used for a long time, store it after removin g t he batteries. Battery leaks may result in fire, injury, etc.

• When the detect or is us ed again after a long-period storage, never fail to perform air calibration. For information on readjustment including air calibration, please contact RKI.

4-6. How to detect

While the detector is ope rati ng in det e ction mode , put th e tip o f the ta pe r nozz le clo se to the det e cti on area and draw sample. The detector measures gas in the ppm range. If a gas is drawn, the detected gas concentration is displayed with the bar meter on the LCD display.

CAUTION

• Before performing gas detection , at tac h th e ta p er no z z le pro v i de d wi t h th e detector to preve nt disturbances by air dust.

DANGER

• Oxygen-deficient air or oth er gases may be discharg e d f rom the gas exhaustin g ou t le t of the detector. Never inhale t he air or gases.

• High-concentration (100% LEL or higher) combustible gases may be discharged from the gas exhausting o ut l et of th e de tector. Never use fire near it.

WARNING

• The detector is designed to draw gases around it under the atmospheric pressure. If excessive pressure is applied to the gas inlet and outlet of the detector, detected gases may leak out from its inside and may cause dangerous conditions. Be sure that excessive pressure is not applied to the detector while used.

• When performing an air calibrati o n, v erify that you are in a fr es h a ir en v ir onment before starting. If interference gases or other gases exist, the adjustment cannot be performed properly, thus leading to dangers when the gas leaks.

• Issuance of a gas alarm indicates t ha t th er e are ex tr e me dangers. Take proper acti ons based on your judgment.

• If a low battery alarm is triggered, gas detection cannot be conducted. If the alarm is triggered during use, turn off the power and promptl y replace the batteries i n a safe area.

• Do not block the buzzer sound opening. No alarm sound can be heard.

• If the main unit is dropped or given a shock, the reading may rise and it may remain so. In such

a case, perform air calibration in a place where the surrounding air is fresh.
