Your PLATINUM has a desiccant dryer incorporated in it to increase the unit’s efficacy
and extend its life. This dryer is filled with a couple of drying agents that remove moisture
from the air. One of the agents, made up of blue silica gel beads, is visible through the
dryer window. As this agent becomes saturated with moisture these beads will turn pink.
Once all of the beads are pink the Desiccant Dryer will need to be replaced to keep your PLATINUM operating at maximum efficiency.
