DRIERITE Desiccant Cartridge
The desiccant cartridge will be partially attached to the detector for shipping.
Prior to use the desiccant cartridge must be fully installed.
The cartridge is held in place on the rear panel of the detector with brackets that
are custom made of stainless steel for Northwest Marine Technology.
The desiccant cartridge is attached via a hose to the upper vent on the detector.
The other barbed end of the desiccant has a hose attached that is open to the
air. The desiccant should go pink from the end that is open to the air. If
the desiccant is turning pink at the end attached to the detector, then this
is an indication of moisture inside the detector and the detector will need
to be dried out. If your detector is wet inside, contact Northwest Marine
Technology
Below are the materials and procedure for attaching your desiccant to your R-Series
Detector.
1. Remove desiccant cartridge from the tunnel of the detector. Two hose
clamps are on the cartridge between the barbs. Remove the yellow plugs
on the ends of the cartridge barbs.
2. There are two brackets, two bolts, 4 washers, 2 nuts, a 6” and a 10” piece
of clear hose, and a white hose clamp.
