SPOTGUN^TM JR. INJECTION SYSTEM

The SPOTGUN^TM JR. Injection System is the world’s most popular injection method for injecting dye into an A/C system without the need to evacuate any refrigerant. It is used to detect leaks in the A/C system.

product SET UP INJECTION GUN SYSTEM

1. Hold the disposable cartridge in an upright position then remove cap and seal from the cartridge.
2. Attach the hose (R-134a) to the top of the disposable cartridge then remove drip cap from the adapter. (Fig. 1)
3. Push the release lever on the injection gun with your thumb, and pull the rod all the way back. (Fig. 2)
4. Install the cartridge into the gun assembly. (Fig. 3)
5. Squeeze the trigger until the piston seats in a disposable cartridge. Now the Injection gun system is ready to be used.

Product OPERATION (R-134a)

1. Connect the injection gun system to the low side port of the A/C system.
2. Inject dye into the A/C system by squeezing the trigger (Fig.
3. See Dye Dose Chart below.
4. Disconnect injection gun system from the A/C port.
5. Attach drip cap to the adapter.
6. Install Dye Service Sticker in a visible location under the hood.
7. Start the engine and turn on the A/C to the maximum for a few minutes. This is to circulate the fluorescent dye in the system.
8. Turn the engine OFF. Check for leaks using an ultraviolet lamp. Possible leak areas will glow a bright yellow/green when exposed to UV light.
9. Note: Smaller leaks may require longer circulation time. Let the A/C system run for a few days then reinspect.

OPERATION (R-134a)

The Injection gun injects the dye into the A/C system without the need to evacuate any refrigerant. To use, proceed with the following steps:

1. Connect injection gun system to the low side port of the A/C system.
2. Inject dye into the A/C system by squeezing the trigger (Fig. 4). See “Dye Dose Chart” below.
3. Disconnect injection gun system from the A/C port.
4. Attach drip cap to the adapter.
5. Install “Dye Service Sticker” in a visible location under the hood.
6. Start the engine and turn on the A/C to maximum for a few minutes. This is to circulate the fluorescent dye in the system.
7. Turn the engine “OFF”. Check for leaks using an ultraviolet lamp. Possible leak areas will glow a bright yellow/green when exposed to UV light.

Note: Smaller leaks may require longer circulation time. Let the A/C system run for a few days then reinspect.
