How to prime a pump on a portable extractor...

especially when it’s new or has run out of water, which can cause an air lock in the pump or line.

Key Points:

1. Why Priming is Needed:

   • Air bubbles in the pump or line can prevent water flow.

   • This often happens when the machine is brand new or runs dry during use.

2. Method 1 – Using a Quick Connect:

   • Insert a male quick connect into the machine’s outlet.

   • Turn on the pump; water should flow out to remove air.

   • Use a bucket to catch water if the outlet is near the floor.

3. Method 2 – Open-Ended Solution Line:

   • Connect a cut hose to the machine and turn on the pump.

   • Let the water discharge into the vacuum inlet to purge air.

4. Signs of Air in the Line:

   • Spitting or sputtering water means air still needs to be cleared.

5. Machines with Bypass Valve:

   • Some machines include a valve that simplifies priming.

   • Open the valve with the pump on until the sound stabilizes, then close it.

6. Common Mistake – Valve Left Open:

   • If water pressure is weak or missing, check the valve.

   • It should be closed during use and only opened for priming.
