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).

Purging Disposable Cartridge Type Injector

• Hold the cartridge (2) upward while unscrewing the cap. Snap
the hose assembly (3) onto the cartridge, and coupler (4) or
(4A) to the hose assembly.

• While holding the assembly upward, attach the handle (1) to

the bottom of the cartridge by turning it clockwise. Continue
turning while dye enters the hose and pushes the air up. Use
a pen to press the depressor of the coupler (4) to release the
air if necessary. Repeat this process as needed until dye
appears at the coupler’s end.

Purging Refillable Cartridge Type Injector

• Hold the dye injector (upward while unscrewing the cap/hose
assembly (2B). Turn the handle of dye injector (1) counter
clockwise all the way before filling. Fill the injector with dye.

Replace cap/hose (2B), tightening securely and attach coupler

(4) to the hose assembly.

• 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 (4) to release the air, if necessary. Repeat this
process as needed until dye appears at the coupler’s end.

B. INJECTION
