Operation

The GURU CH may be thought of as an automatic freeze-out plug with one important difference: The stainless steel GURU Cartridge releases itself from its body at a pre-set water temperature (35°F or 40°F), rather than being forced out by the tremendous pressure of expanding ice. This provides almost a full one inch bore to rapidly drain the typical compressor before damage can occur. Resetting and rearming the GURU Plug is easily accomplished by simply reheating the cartridge and utilizing our GURU Flag and Clip tool with slotted actuator feature. This feature prevents the GURU Plug from triggering open again while refilling the cooling system with cold water.
