1. Introduction

This manual provides essential instructions for the safe and effective operation, maintenance, and troubleshooting of the Gastec GV110-S-TR Gas Sampling Pump with Stroke Counter. This device is designed for accurate measurement of gas and vapor concentrations using Gastec Detector Tubes.

The Gastec Detector Tube and Pump System is engineered for ease of use while maintaining high safety standards. Please read this manual thoroughly before operating the pump.

2. Safety Information

Always adhere to local safety regulations and guidelines when using the Gastec Gas Sampling Pump. Failure to follow safety instructions may result in inaccurate readings, personal injury, or damage to the equipment.

• Use only genuine Gastec Detector Tubes with this pump.
• Ensure the pump is in good working condition before each use.
• Do not attempt to repair the pump yourself; refer to qualified service personnel.
• Wear appropriate personal protective equipment (PPE) as required by the sampling environment.
• Avoid direct contact with the contents of broken detector tubes.

3. Product Overview and Components

The Gastec GV110-S-TR Gas Sampling Pump is a robust, hand-operated device designed for precise air sampling. Key components include:

• Pump Body: The main housing of the pump.
• Stroke Counter: Indicates the number of pump strokes performed.
• Thermal Ring: Displays ambient temperature, aiding in temperature correction for certain measurements.
• Tip Breaker: Used to safely break the tips of detector tubes.
• Flow Finish Indicator: Confirms the completion of a sampling stroke.
• Detector Tube Holder: Secures the detector tube during sampling.

What's Included:

• Gastec Gas Sampling Pump (GV110-S-TR)
• Thermal Ring (integrated)
• Semi-rigid carrying case with adjustable shoulder strap
• Multi-language instruction manual (this document is a supplement)
• Spare parts kit (1 lubricant and 3 rubber tube holders with filter)

4. Setup

Before initial use, ensure all components are present and undamaged. Familiarize yourself with the pump's parts as described in Section 3.

1. Inspect the Pump: Check the pump body for any visible damage. Ensure the piston moves smoothly.
2. Check Accessories: Verify that the carrying case and spare parts kit are complete.
3. Prepare Detector Tube: Select the appropriate Gastec Detector Tube for the gas or vapor to be measured. Carefully break both ends of the detector tube using the integrated tip breaker on the pump.
4. Insert Detector Tube: Insert the detector tube into the rubber inlet of the pump with the arrow on the tube pointing towards the pump. Ensure a snug fit to prevent air leakage.

5. Operating Instructions

Follow these steps for accurate gas sampling:

1. Prepare for Sampling: With the detector tube inserted, position the pump in the area where the gas concentration needs to be measured.
2. Perform a Full Stroke: Pull the pump handle out completely until it locks into place. This constitutes one full stroke. The stroke counter will advance by one.
3. Observe Flow Finish Indicator: Wait for the flow finish indicator to appear. This confirms that the required volume of air has been drawn through the detector tube. The indicator is typically a red dot or line that appears when the flow is complete.
4. Repeat Strokes (if necessary): If the specific detector tube requires multiple strokes, push the handle back in and repeat steps 2 and 3 for the specified number of strokes. The stroke counter will keep track.
5. Read the Detector Tube: After completing the required strokes, remove the detector tube and read the concentration directly from the scale on the tube, following the tube's specific instructions. Note the ambient temperature from the thermal ring for any necessary corrections.
6. Dispose of Tube: Properly dispose of used detector tubes according to local regulations.

Note: Always refer to the specific instructions provided with each Gastec Detector Tube for accurate sampling times and number of strokes.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your Gastec Gas Sampling Pump.

• Cleaning: Wipe the exterior of the pump with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Lubrication: Periodically apply a small amount of the provided lubricant to the piston shaft to ensure smooth operation. Refer to the spare parts kit for lubricant.
• Rubber Inlet Replacement: If the rubber inlet (tube holder) becomes worn or damaged, replace it with a new one from the spare parts kit to maintain an airtight seal.
• Storage: Store the pump in its carrying case in a clean, dry environment away from direct sunlight and extreme temperatures.
