3.1 Manual sample-draw kit The manual sample-draw kit is composed of a sample-draw probe, tubing 10’, a squeeze bulb, and an adapter that is used to connect the sample-draw accessories system to the IQ Force. NOTE The maximum amount of tubing that can be used with the manual sample-draw kit is 50 feet. However, it is generally recommended for lengths greater than 20’, a motorized sample draw pump accessory should be considered as more practical. 3.1.1 Manual sample-draw kit usage To use the manual sample-draw kit. Connect the short section of hose that comes off the squeeze bulb to the sample-draw adapter. To test the seals in the sample-draw system, squeeze the aspirator bulb, then cover the end of the sample-draw probe with a finger. If there are no leaks in the sample-draw kit components, the bulb should stay deflated fora few seconds. Secure the calibration adapter (with the sample-draw assembly attached) to the IQ Force by sliding it onto the instrument. Make sure the securing tabs latch onto their respective surfaces.
