If you have a smaller unit, please contact us. If the a/c system that will not hold a vacuum, you need to use the Enviro-Safe Prodry XL4. The reason for the vacuum or the use of Enviro-Safe Prodry XL4 is that it will eliminate moisture in the system. Moisture mixing with oils and refrigerant can cause you system to make sulfuric acid which will corrode and eat your system! For larger units over 5 tons, we suggest you use the Enviro-Safe Seal XL4 Direct Inject. These are available in various of the larger sizes. Even though Proseal XL4 can form a seal on the Schrader valve, when you hook up to it the seal will release and allow you to use the Schrader if necessary. If there is still Proseal XL4 in the system it will reseal the Schrader. Can be used as a system-protector against system failure. Protects against leaks formed by corrosion. Enviro-Safe ProDry contains a dehydrating agent that converts system moisture into oil. We recommend the use of ProDry XL4 before the use of Enviro-Safe Seal XL4 to ensure all moisture has been removed from the air conditioning system. Should be used on any home A/C system that has leaked below 15 psi (running or not running) or if the system has ever leaked below 15 psi in the past.
