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.
