HIGH PRESSURE LEAK DETECT
HIGH PRESSURE LEAK DETECT allows an operator to pressurize a component or system to detect a difficult
to locate leak prior to checking with an external leak detector. Recommend to start process with an internal
system capacity of 8 to 10 LB (3.63 to 4.54 KG). Use of a leak detector meeting newest standard SAE J2791
or later is suggested.

At the main menu screen, press the ▲ key 4 times.
Press START key.
Using the alphanumeric keypad, enter the final target
pressure for the system or component under test.
Recommend a setting of 90 PSI for most applications.
Press START key to continue.
The RHS980C will begin building internal pressure to
the specified target amount.
If the unit has failed to build the desired pressure after
30 minutes, the screen to left is displayed. Add
refrigerant to the internal cylinder and retry procedure.
Press START key to continue.
After reaching the target pressure, the unit will charge
the system or component with liquid refrigerant. Press
the STOP key to abort the operation.
When charge is complete, the screen shown will
appear. Check for system leaks using a leak detector.
Refrigerant must be recovered after leak check is
completed.
WARNING
DO NOT START VEHICLE AC SYSTEM IF HIGH PRESSURE LEAK DETECT
PROCEDURE WAS USED. COMPRESSOR DAMAGE COULD RESULT. A RECYCLE
PROCEDURE MUST FOLLOW LEAK DETECT.
