2.5.2 MOUNTING THE FTS SUPPLIED DESICCANT AIR DRYER
Refer to the manufacturer’s instructions for important details and safety information about the air
dryer and desiccant.
You will need the following tools to mount the air dryer:
• Drill with bits
• 9/16 wrench
• Flathead screwdriver
• Teflon tape
IMPORTANT INSTALLATION POINTS:
• Observe the safety precautions when using the blue silica gel desiccant (section 2.5.1)
• Each Bubbler must have a dedicated desiccator and air intake path; do not use one
desiccator for multiple Bubblers (this can cause spikes in the data);
• The entire air intake path from the desiccator’s air intake line to the Bubbler’s air intake
fitting should have no restrictions (e.g. check valves) as this can cause spikes in the data;
• The air dryer should be installed as close as possible to the Bubbler’s air intake with the air
flow going in the direction of the arrow (see Figure 2-4);
• There should be no kinks or tight bends in the desiccant hose;
• There should be no obstruction above the mounting bracket to permit the insertion and
removal of the air dryer.
1) Using the supplied screws, mount the bracket.
2) Depress the release button on the clamp ring and rotate the housing to remove the protective
metal bowl.
3) Maintain a firm grip on the bowl and separate the top housing from the bowl.
4) Keep the central tube covered to prevent silica gel from entering it. Fill the bowl with desiccant
to 1/8” below the inner step of the bowl. Shake or tap the bowl to settle the desiccant and add
more desiccant if required. Refer to Figure 2-3.
