 Scrub the faces of the Peak Combo Sensor/Slimline Peak
Combo Sensor with a soft bristle brush.
 Confirm that all sensor cables are neatly arranged, securely
fastened, and free of debris, cuts, kinks, and breaks that may
affect performance. Replace any sensor that has a damaged
cable.
When handling, storing, or packing the Surface Combo Sensor,
avoid contacting the metal cable connector with the crystals on the
sensor. This could damage the Teflon coating covering the crystals.
Replacing the Pressure Depth Sensor Dryer Tube
or Desiccant
All combo sensors with a pressure depth sensor and the ultrasonic
depth sensor with the pressure option include a pressure depth
sensor dryer tube. This tube contains desiccant that absorbs the
moisture from the air traveling through the dryer tube into the clear
plastic tubing leading to the pressure depth sensor in the pipe.
Replace the dryer tube or the desiccant contained within the dryer
tube on a regular basis or as necessary. Desiccant can absorb
moisture only when it is blue in color. Pink desiccant indicates that
it can no longer absorb moisture. Therefore, if the desiccant
appears either colorless or pink upon inspection, replace the dryer
tube or desiccant immediately.
Replacing the Dryer Tube
Replace the pressure depth sensor dryer tube (p/n 3704-0032) in the
following way:
1. Clip the cable ties securing the dryer tube to the monitor.
2. Cut the clear flexible tubing running from the dryer tube to the
pressure depth sensor connector at the location close to the
brass barbed fitting on the dryer tube.
3. Set aside, but do not discard, the old dryer tube with the used
desiccant.
