specifications The detector has different specifications depending on the standards or explosion-proof certification type. Check the specifications of the product you have before use. See the Declaration of Conformity at the end of this operating manual for CE marking specifications. For the product specifications, check the nameplate attached to the product shown in the following figure.
Important Notices on Safety To maintain the performance and use the detector safely, observe the following instructions of DANGER, WARNING, and CAUTION. 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.
2-2. Warning cases WARNING Sampling point pressure • The concentration meter is designed to draw gases under the atmospheric pressure. If excessive pressure is applied to the gas inlet and outlet of the detector, measured gases may leak out from its inside and may cause dangerous conditions. Be sure that excessive pressure is not applied to the detector’s inlet or outlet during use.
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 place where the detector is exposed to liquids such as oil and chemicals. •...
Page 8
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. •...
2-4. Safety information (for ATEX/IECEx specifications) Portable gas leak detector SP-220 is a gas detector to continuously detect combustible gases. The detector draws gases with the internal micro pump. Use only two TOSHIBA AA alkaline batteries (LR6T) connected in series for power supply. Do not replace the dry batteries in a hazardous location.

CAUTION • Never fail to turn off the power of the detector before replacing the batteries. • Replace the batteries in a safe place. • Replace both of the two batteries with new ones at one time. • Pay attention to the polarities during replacement. Replace while checking the battery polarities stamped on the body.
4-4. How to start the detector When the power is turned on, a self-diagnostic starts, and then the detector enters the detection mode. Power-on Press and hold the POWER button until the buzzer blips (one second or longer) to turn on the power. When the power is turned on, the LCD display changes automatically as shown below, and the detector enters the detection mode.
Page 16
NOTE • When powering on after leaving the detector for more than five minutes with the batteries removed, such as when powering on for the first time, replacing the batteries, etc., or powering on with the batteries inserted with incorrect polarities, a clock abnormality (FAIL CLOCK) may be triggered. When it is reset using the MODE button, the detector moves to the date/time setting screen.
4-5. Basic operating procedures The detection mode is used after power-on. Gas is detected in the ppm range. button buttons Hold down for Hold down for Hold down for 1 sec 3 secs 3 secs Illumination lamp lights <Operation/alarm sound ON/OFF> <Peak clear>...
4-6. How to detect While the detector is operating in detection mode, put the tip of the taper nozzle close to the detection 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.
4-7. Changing the alarm setpoint In the detector, the alarm setpoint is factory set to 30 ppm. The detector has 5 preset alarm setpoints that the user can cycle through (10 ppm, 30 ppm, 150 ppm, 500 ppm, and 2000 ppm). How to change the alarm setpoint 1 In the detection mode, press the AIR and MODE buttons at the same time.
4-8. Performing air calibration After a high-concentration gas is detected or an alarm is triggered by temperature/humidity changes, perform an air calibration in the measured atmosphere. * Before performing air calibration, verify a fresh air environment. In the detection mode, hold down the AIR button.
NOTE • Perform air calibration under pressure and temperature/humidity conditions close to those in the operating environment and in fresh air. • Perform air calibration after the reading is stabilized. • If there is a sudden temperature change between the storage and operational locations, turn on the power of the detector, let it stand for five minutes or more in a similar environment to the operational location, and perform air calibration in fresh air before using it.
4-10. Peak hold function When the peak hold function is enabled, the latest peak value is always displayed with the bar meter. In the detection mode, hold down the MODE button (for three seconds or longer). The peak hold function is enabled.
4-12. How to turn on the illumination lamp The illumination lamp can be turned on, if necessary. Hold down the AIR and POWER buttons at the same time (for three seconds or longer). The illumination lamp lights up. The illumination lamp will automatically go off two minutes after it lights up.
Display Mode 5-1. Entering the display mode This mode allows users to view and change various display settings. (Display example: For city gases) In the detection mode, press the MODE button. The detector enters the peak value display in the display mode.

Replace the hydrophobic filter with a new one. Make sure it’s seated in the rubber seal correctly. Hydrophobic Filter Rubber seal Attach the rubber seal, with the hydrophobic filter installed, to the cap. Make sure the rubber seal’s rib has been firmly inserted into the cap’s groove.
Page 38
Interference gas removal filter (CF-8392) replacement procedure The interference gas removal filter (CF-8392) is installed to the detector to remove interference gases that damage sensors for silicone, sulfides, etc. Continuing to use the detector may cause the filter to be contaminated or clogged. Replace the filter when it has absorbed water or oil, etc.
9-1. Fresh Air Adjustment RKI Instruments, Inc. recommends that the fresh air adjustment be performed in a fresh air area (area known to be free of toxic and combustible gases and of normal oxygen content, 20.9%). If a fresh air environment is not available, a cylinder of zero air can be used as long as the gas is applied through a humidifier tube.
