CHECK REFRIGERANT LEAKAGE USING ELECTRICAL LEAK DETECTOR WARNING: Never check refrigerant leakage while the engine is running. CAUTION: Be careful of the following items so that inaccurate checks or misidentifications are avoided. when leakage occurs. 1. Stop the engine. 2. Connect recovery/recycling/recharging equipment or manifold gauge set to A/C service valve. 3. Check that A/C refrigerant pressure is 345 kPa (3.52 kg/cm 2 , 50 psi) or more when temperature is 16 ° C (61 ° F) or more. When pressure is lower than the specified value, recycle refrigerant completely and fill refrigerant to the specified level. 2 , 50 psi) or less when temperature is less than 16 ° C (61 ° F). 4.

Always continue and complete checking along all pipe connections and A/C system components for additional leakage. • When a leakage is detected, clean leakage area using compressed air and check again. probe surface may not be exposed to water or dirt. NOTE: maximum fan speed while the engine is stopped, and then insert electrical leak detector probe into drain • When disconnecting shut-off valve that is connected to A/C service valve, always evacuate remaining refrigerant so that misidentification can be avoided. 5.
