Checking the Gun for Proper Function
View Video in: Windows Media Player - Flash Player
Good quality foam is dependent upon one-to-one ratio dispensing. The easiest way to determine that you have good ratio is to observe the stream of chemicals coming out of the gun before they pass through the mixing nozzle.
To do this, remove the nozzle from the gun and point the gun into a waste container. Pull the trigger and observe the chemical streams. You should see two chemical streams crossing over each other and flowing at equal velocity.
Know that the "A" component is light brown in color and the "B" component is white (or nearly clear) in color.
If you see more "A" chemical flowing than "B" chemical, your foam is probably darker in color and may have a crunchy, glassy surface. First check the temperature strip - is the chemical cold. Cold chemicals will result in foam that is "A" component rich. If the temperature strip indicator is in the blue section, warm the tanks, shake them vigorously, and check the chemical flow again.
If the temperature strip indicates the mid-green section, meaning the temperature is right for dispensing, then check the "B" component tank. Be sure it is not empty. Be sure the valve is turned all the way on.
If all of these things seem to be right, contact us for further action.
If you see more "B" component than "A" component, your foam is probably whiter in color with a spongy surface texture. First check the temperature sensing strip - is it indicating in the red section? Chemicals that are too warm often result in foam that is "B" component rich. Cool the chemicals, shake the tanks vigorously and check the chemical flow again.
If the temperature seems right, check the "A" component tank. Be sure that it is not empty. Be sure the valve is turned all the way on.
If all of these things seem to be right, contact us for further action.
In very extreme cases, you may dispense foam that seems to be rising, then it "melts" or reverts to a liquid after a short period of time. This would indicate that there is no "A" component flow at all.
When was the last time you used the system? We strongly recommend that the gun is dispensed a minimum of once every week, more often in humid climates. Failure to do so will result in a blockage on the "A" component side of the gun.
If there is no chemical flow, the gun/hose assembly will need to be changed. Contact your distributor for more information.
If you do not seem to be getting acceptable flow from both components, this would indicate a lack of pressure. The only known cause for both tanks to loose pressure is if the kit was used while lying on its side. The chemical tanks are similar to aerosol cans. If you dispense foam while they are on their side, the propellant escapes through the hose and the pressure is lost. There is no remedy for this. You can only prevent this from happening by keeping the systems in their upright position during use.
