What This Receiver Drier Helps Address

• Moisture contamination in the A/C refrigerant circuit
• Reduced cooling performance caused by a saturated desiccant
• Debris control at the HVAC receiver drier location
• Leak concerns at pad mount sealing surfaces

Installation Notes and Tips

Verify pad mount fitment, inlet/outlet orientation, and switch port configuration before installation. Replace the green O-rings listed for the application and inspect mating surfaces for corrosion or damage. Because the desiccant is not replaceable, install the receiver drier only after the system has been properly evacuated and any contamination source has been corrected.
