INTRODUCTION

Thank you for purchasing General Tools & Instruments' (General's) RLD440 Digital Dual
Mode Refrigerant Leak Detector. Please read this user's manual carefully and thoroughly
before using the product.
The RLD440 is equipped with two leak detection technologies that can be used
separately or in concert. Its long-lasting solid electrolyte semiconductor sensor can
detect and gauge the size of leaks of all halogenated (chlorine or fluorine-based)
refrigerant gases currently in common use. They include HFCs (hydrofluorocarbons),
CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons).
Specifically, the instrument can detect:
• Widely used HFC refrigerants such as R-134a, R-410a, R-404a, R-407c and R-507
• CFC refrigerants such as CFC-12 (R-12)-commonly known as Freon
• HCFC replacement blends, such as R-22, approved by the U.S. EPA for complying with
the stratospheric ozone protection provisions of the Clean Air Act
• R-1234yf, the newly approved hydrofluoroolefin (HFO) refrigerant with a global
warming potential 335 times less than that of R-134a
