What if I have a problem with my Direct Inject?

• The hose is manufactured with a low flow valve. This safety feature prevents any refrigerant from escaping out of the hose when it is screwed onto the unit for use. This safety feautre also keeps the installation of the product EPA complient. ​Because of this low-flow valve, when the user screws the hose on, the first o-ring will form a seal over the port causing the user to feel some initial tension, however, it is important that the user continues to screw the hose all the way down past this tension until it is tightly sealed before they inject the product into their system.

         Note: The product will ONLY inject if the hose is screwed down past the inital tension and fully sealed.

When using the CO2 gun, if the inject is not fully sealed, the user will pressurize the inject making it extremely difficult for the inject to be screwed all the way due to the pressure that as  been created inside

• Make sure the AC unit is turned on before using the inject. The fan on the outside unit should be running, however, the user MUST also pay attention to insure the compressor is energzed/engaged
• If the inject does not inject, check to see if the AC unit is equipped with an internal shut off valve. Some AC units have a large acorn cap over the stem of the valve. The valve stem will be square. These must be opened when ready to inject. User must have the inject all the way screwed on and ready to inject BEFORE opening the valve before it can be used.
• When using gas to inject the product, connect the manifold to the refrigerant tank and inject. You must make sure there is refrigerant in the tank. Open the valve of the refrigerant tank and invert the tank for liquid refrigerant. Bleed the hoses on the manifold set, then lastly, make sure to open the low side valve to allow a minimum flow of refrigerant which will push the product into the system.
• Check the Schrader valve to make sure that it is close to being flush or slightly below the side port. This valve must get depressed in order for the product to inject. If the valve is deep, use a Schrader tool and raise the valve so the inject will flow into the system.
• Make sure the depressor in your charging hose is not bent or damaged.
• If the user has a low flow valve on the hose of the manifold set, make sure to screw to screw the connection all the way down on the inject to depress the valve.
