DESCRIPTION
The GCT External Pump is an accessory device to be used with Gas Clip Technologies portable gas detectors, powered by a rechargeable battery. The GCT External Pump is worn on the user’s body and does not require regular interaction to perform its function.
The device draws sample air from an inlet and delivers it through an output port and a hose to a compatible calibration cap mounted on a GCT gas detector. During operation, a hose that is up to 75 ft. (23m) long with 1/8” ID can be connected to the inlet to allow environmental sampling in confined spaces before entry into the space. For hose lengths up to 50 ft. (15m), GCT offers tubing that will not oxidize, is able to bend around sharp curves, and easily works with GCT External Pump accessory fittings. For tube lengths over 50 ft. (15m), GCT recommends using tubing with even higher resistance to reactive chemicals (e.g. H2S). Please contact GCT for tubing selection recommendations. The GCT External Pump should be used only when remote sampling. Once the area in question has been cleared for entry, disconnect the GCT External Pump and calibration cap from the gas detector in order to resume normal detector operation.

LED DEFINITIONS

BASIC OPERATIONS

SET UP
Connect a 3 ft. hose from the gas outlet port to a Gas Clip Technologies detector with a calibration cap. Next, connect a 10 ft. sampling hose from the gas inlet port to a diffusion stone. Accessories such as the Quick Disconnect, Sampling Probe, or Telescoping Sampling Probe can also be attached to the GCT External Pump with various lengths of sampling hose (up to 75 ft.).

TURNING ON THE DEVICE

To activate the GCT External Pump, press and hold down the power button for 5 seconds. Once the device is activated, the startup sequence will consist of the following:

1. The power LED is green and begins to flash slowly.
2. Audible alarm chirps.
3. The flow LED is green and begins to flash slowly.

For additional flow, power, and charging status clarification, refer to the LED Definitions chart.

BLOCKED FLOW TEST
It is critical to check if the pump is fully operational before each day’s use. This is accomplished by conducting a blocked flow test. With the power on, block the free end of the sampling hose which is attached to the gas inlet port. The GCT External Pump will display the following behavior:

1. The pump motor shuts down.
2. The audible alarm beeps continuously indicating a flow fault.
3. The flow LED turns red and flashes quickly.

Upon successful completion of the blocked flow test, press the power button to reactivate the device. Warning: Failure to detect a block may indicate a leak in the sampling system. If the GCT External Pump fails the blocked flow test, perform the following checks:

1. Check the gas inlet port and gas outlet port for blockage.
2. Check pellet filter and hydrophobic filter for blockage.
3. Check all attached sampling hoses for leakage.
4. Once the blockage and/or leakage has been resolved, press the power button to reactivate the device.

Users must perform these operational checks before each use. If the audible alarm does not activate when the blocked flow test is performed, do not use the GCT External Pump. This could be an indication that the device is faulty and would lead to inaccurate readings by gas detection devices. Failure to follow the instructions above can result in serious personal injury or death.

BUMP TEST
When bump testing a detector connected to the GCT External Pump, please refer to the bump test instructions in that specific detector’s user manual since the instructions for different detectors may vary. Gas Clip Technologies recommends performing the bump test of a GCT detector with the GCT External Pump connected as described below.

1. Connect the detector, calibration cap, GCT External Pump and hoses as seen in Figure 1.
2. Check the following connections for a tight fit— The calibration cap snapped over the detector’s sensor ports
3. Connection hose attached to the calibration cap and the GCT External Pump’s gas outlet port
4. The sampling hose affixed to the GCT External Pump’s gas inlet port
5. Turn on the detector and GCT External Pump.
6. Activate the bump test on the detector. (See the detector’s user’s manual for instructions.)
7. When the detector indicates it is time to apply gas, connect the sampling hose to the demand flow regulator on your gas cylinder as shown in Figure 2.
8. The bump test is successful when all the sensors have gone into alarm. If any sensor does not go into alarm within 2 minutes, then the bump test has failed.
9. Disconnect the sampling tube from the demand flow regulator. The detector will return to normal operation after a brief period.

When a bump test fails, the detector will show: “L. BUMP FAILED.” Do not use the detector unless the bump test passes. If the bump test fails, perform the following checks:

1. Check the setup for any blockage or leakage in the hose connection from the gas outlet port to the calibration cap of the detector.
2. Check for any blockage or leakage in the hose connection from the gas inlet port to the demand flow regulator.
3. Check that the GCT External Pump is not indicating abnormal operation by red fast flashing LEDs &/or audible alarm beeping.
4. Check the pellet filter and hydrophobic filter. Refer to the “Filters” section on page 9 for more information.
5. Check the detector filter for blockage.
6. Once any blockage, leak, and/or filter issue has been detected and resolved, activate the pump and the detector. Then repeat the bump test.
7. If failure persists, contact the Gas Clip Technologies Service Department for further assistance.

TURNING OFF THE DEVICE
Press and hold the power button for 5 seconds until the three LEDs (power, flow, and charging) turn off. Then release the button.

LOW BATTERY WARNING
Typically, 20 minutes of operation time remain when an audible alarm begins beeping every 10 seconds and the power LED starts to intermittently flash red. However, the time remaining can vary depending on the age of the batteries, the temperature of the environment, and other contributing factors. Therefore, in the event of a low battery warning, exit the work area immediately since the GCT External Pump could turn off at any time. For more power LED and beeper pattern information, refer to the LED Definitions Chart.

DEVICE MAINTENANCE

BATTERY
To check the battery state of charge (SoC), power up the device, observe the power LED, and refer to the LED Definitions on page 4. To charge the GCT External Pump, connect the provided charger to the charging port, and then plug the charger into an AC outlet.  When connected to a charger, the device will shut off power to the motor and turn off the flow and power LEDs. The charging LED will indicate the charge status. Once the battery is fully charged, the charging LED will blink green every 2 seconds.

• DO NOT charge the device in a hazardous area.
• DO NOT charge the device in temperatures below 32°F (0°C) or above 113°F (45°C). Charging at room temperature is recommended.
• DO NOT substitute any other battery type unless specified and supplied by Gas Clip Technologies.
• DO NOT use any charger other than what is supplied or offered by Gas Clip Technologies as this may damage or improperly charge the battery.

GCT recommends recharging the device whenever the power LED indicates that there is less than 40% SoC remaining this will extend the overall life of the battery.

STORAGE
Store the GCT External Pump in a safe, cool, dry place between 32°F(0°C) and 77°F(25°C). After storage, check the power remaining in the battery and charge if necessary. Also, perform a blocked flow test before use. If the GCT External Pump will be stored and unused for months, periodically turn it on. Charge the battery when the power LED indicates less than 40% SoC. GCT recommends checking the device every 6 months or more often.

FILTERS
A hydrophobic membrane filter and a particulate filter are located under the gas inlet. Together they provide protection against liquid and particulate ingress. It is imperative that both filters be installed properly before using the GCT External Pump in order to protect against internal damage to the device. Periodically perform visual inspections using the filter window on the back of the accessory to determine if they require replacement. Ensure the filters are clean and free of moisture and debris since clogged filters could delay sampling speed and cause the GCT External Pump to use more power thus resulting in a shorter battery run time. If these filters become completely blocked, then the device will be unable to continue sampling and will initiate a pump-blocked alarm. To replace the filters:

1. Loosen the two screws holding the gas inlet housing in place and remove the gas inlet housing.
2. Replace the hydrophobic and/or particulate filter as required and reassemble the gas inlet.
3. Perform a blocked flow test to ensure operational readiness. (See page 5 for instructions.)

CLEANING RECOMMENDATIONS AND ROUTINE CARE
Clean the GCT External Pump case with a soft damp cloth periodically.

1. DO NOT use harsh solvents or chemicals as these products could compromise the intrinsic safety of the device.
2. DO NOT use products containing silicones or alcohols since they can interfere with or damage detector sensors.
