6. Operating Procedure

6.1 Fixing Sampling Pump to Extension Pole (When Using Detector Tube)

(1) Take the pump holder off from the bracket.
Unscrew and remove the screws. Pull the pump holder up.

(2) Attach the pump holder to the sampling pump. Attach the pump holder from the inlet side of the sampling pump.

• Align the open side of the pump holder and the tip breaker of the sampling pump to avoid the pump holder from getting stuck. Do not widen the pump holder too much.

• Set the pump holder at the middle of the sampling pump body and turn the sampling pump 180 degree as the guide mark (red line) can be easily seen.

(3) Attach to the bracket

• Attach the pump holder to the bracket from directly above.

• Fix the pump holder to the bracket using the screws, spring washers, and nuts. *Tighten the screws temporally to adjust the position before fully tighten them.

6.2 When Using Detector Tubes

(1) Prepare the detector tube. Select the detector tube that suits your purpose and check the specifications of the detector tube. Expiry date, number of pump strokes, presence or absence of pretreatment tube. If there is interference gas, check how its concentration affects the detector tube.

NOTE:  Check the storage temperature and expiration date of the detector tube to be used before use.

(2) Check the airtightness of the sampling pump.

When the sampling pump is not attached to the extension pole, check the airtightness of the sampling pump according to the instruction manual of the sampling pump before attaching it to the extension pole.

(3) Attach the sampling pump on the extension pole.

After confirming the airtightness of the sampling pump, attach it on the extension sampling pole according to “6.1 Fixing Sampling Pump to Extension Pole”.

(4) Insert the nipple adapter at the tip of the extension tubing into the inlet rubber of the sampling pump.

(5) Check the airtightness of the sampling pump and the extension pole. When the sampling pump is already fixed to the extension pole, check the airtightness according to the following procedures.

1. Confirm the inlet nut of the sampling pump is firmly tightened.

2. Attach the unbroken detector tube to the rubber shroud.

3. Connect the rubber shroud to the tip of the extension pole.

4. Confirm the pump handle is fully in. Align the guide mark (red line) on the back plate and guide mark ( 100) on the handle.

5. Pull out the handle fully along the guide line of the shaft until it is locked.

6. When checking the airtightness of the sampling pump alone, wait for 1 minute after
   (5.) But when the extension pole is connected, the volume of the extension tubing is also related. Repeat  (4.) and (5.) 4 times. At 4th time  of (5.) , lock the pump handle and wait for 1 minute.

7. After 1 minute, unlock the handle by turning it more than 1/4 turn and guide
   it back gradually. Confirm the handle returns to its original position. At this time, if the guide line of the shaft cannot be seen, it can be confirmed that the airtightness is good, so move on to (6).

8. If the pump handle doesn’t return to its original position in (7.) , check the airtightness of the sampling pump alone according to the instruction manual of the sampling pump.

9. If it can be confirmed that the airtightness of sampling pump alone is good in (8.) , it is suspected that there is a problem with the airtightness of the extension pole, so please contact your Gastec representatives for repair.

(6) Break off both ends of the detector tube by using the tip breaker.

(7) Attach the detector tube to the rubber shroud.

(8) Make sure that the arrow on the detector tube is pointing toward the sampling pump and the detector tube is firmly attached.

(9) Extend the extension pole.

1. Take the extension tubing out from Belt
2.  Extend until the joints are certainly fixed.
3. When extending the extension pole, make sure the extension tubing don’t get stuck.

(10) Keep the detector tube stable as much as possible. Confirm the pump handle is fully in. Align the guide mark (red line) on the back plate and guide mark ( 100 or 50) on the handle. Pull out the handle fully along the guide line until it is locked. Wait until the sampling time has elapsed.

(11) Check the completion of the sampling of 100 mL or 50 mL by the flow finish indicator on the handle.

(12) Remove the detector tube from the sampling pump, and immediately read the scale at the end of color change layer.

(13) If the tube reading requires correction, correct the tube reading in order of temperature, humidity, number of pump strokes, and ambient pressure.

(14) Fold the extension pole.

1. Loosen each joint.
2. Fold the extension pole pulling out the extension tubing to prevent it from getting stuck inside the pole.
3. Bundle the extension tubing with Belt B.

6.3 When Using Pump Type Gas Detector

1. Prepare the pump type gas detector. Follow the instruction manual of your gas detector for preparation and operation.
2. Remove the nipple adapter at the tip of the extension tubing, and connect the extension tubing to the gas detector using the hose end and joint nut for GOH-1A, GOC-1A, etc., or using the auto joint for GOM-3A, MA2510, MA0510, etc.
3. Extend the extension pole to the measurement point, keep the tip of the extension pole stable as much as possible, and measure the gas concentration. See 6.2 (9) and 6.2 (14) for extension and contraction of the extension pole.
