3.6.1 Filter Drier Replacement
3.6.1.1 When to Change Cores
Cores should be changed when they become contaminated. Disposal of the cores should be
handled according to local law.
• Solids – Cores that become contaminated with solid particles should be changed
whenever the pressure drop increases to the point where it reduces system
performance.
• Moisture – When moisture is the major concerns, change the drier when the
Moisture and Liquid Indicator color is in the caution or wet range. The action of
the indicator element is completely reversible and will change color whenever the
moisture content of the system changes, see Section 2.17.
• Other – When either acid or wax is the major contaminant involved, the cores
should be left in the system at least three days to come to equilibrium thereby
removing the maximum amount of contaminants.
The cores will remove their maximum amount of moisture and come to equilibrium in
approximately one day of operation. Many users of replaceable core will change the cores
every spring and fall as part of their normal maintenance schedule.
3.6.1.2 Instructions for Assembly and Charging Cores
Filter drier cores are shipped in metal cans that are dried and hermetically sealed to protect
the cores from contamination by moisture and dirt. The detailed instructions for assembly and
