VII. Desiccant
CHANGING THE DESICCANT
1. Disconnect the tubing from both sides of the column.
2. Lift the column straight up and off of the box.
3. Turn the column over, lid up, and slowly unscrew the lid.
4. Remove the metal retainer, O-ring, and spring on top of the desiccant.
5. Pour out old desiccant, refill, tapping the column gently on a table to help settle the desiccant.
6. Replace the metal retainer, O-ring, and spring. Tighten lid.
7. Replace the column onto the box and reconnect tubing.
RENEWING THE DESICCANT
The desiccant can be renewed approximately ten (10) times before having to be replaced. The granules should
be removed from the drying column and spread evenly, one granule deep on a tray. The desiccant should then be
heated for approximately one (1) hour at about 400° F (200° C), or until all the indicating granules turn from gray
to blue. The material should be allowed to cool in an airtight container before refilling the plastic column.
