Product Description

How a Trinary Switch Works

  • Prevents the compressor from operating of system charge is lost or ambient temperature is too low
  • Stops compressor if head pressure increases to unsafe levels
  • Automatically resets when pressure drops back to normal
  • A shutter/fan override switch keeps head pressure within normal range by opening shutters or operating engine fan to increase air flow across condenser when head pressure rises above set level.

Installation

  • Install trinary switch on liquid side of A/C system between condenser and expansion valve
  • Compatible with R-12 and R134a systems
