A. PURGING AIR FROM THE HOSE ASSEMBLY
It is important to eliminate any air in the hose before injecting dye into the A/C system. (This process is necessary only
once for the setup).
1. Hold the dye injector (1) upward while unscrewing the cap/hose assembly (2). Turn the handle of dye injector (1)
counter clockwise all the way before filling. Fill the injector with dye. Replace cap/hose assembly, tightening
securely.
2. While holding the assembly upward, start turning the handle (1) clockwise. Continue turning as dye enters the
hose and pushes the air up. Use a pen to press the depressor of the coupler (3) to release the air. Repeat this
process as needed until dye appears at the coupler’s end.
B. INJECTION

2. Connect injector to the low side service port of A/C system. Hold body of injector. Use ( I ) starting line on handle end

(Approximately 1 to 1 1/4 turn(s) for Concentrated Dye).
(Approximately 3 1/2 turns(s) for Standard Dye).
3. Disconnect injector from the system and clean any excess dye left around the service port
