How do I install the chamber?

  1. Find the slot located on the chamber lid
  2. Line the slot in accordance with the tab in front of the chamber base
  3. Press the tab all the way through the slot
  4. Place the lid down onto the chamber base
  5. When the lid is properly placed and pressed down the PULL flap will snap into place.

Is there any possibility of a water chamber leak?
For the XT Series units, leaks may result when the metal base does not connect to the chamber properly.  To prevent this, make sure the metal base of the water chamber has been pushed to the end to have a good seal.  In addition, the aging of the silicon on the metal base may also cause leakage. If this is the case, please contact your supplier for a replacement of either the silicon band or the one provided by the water chamber.

The tab which held the lid closed on my original water chamber broke, rendering it useless. I ordered this one which is an improved design. It holds more water and the goofy lid is gone. You fill it through the upper hose connector. My machine is MUCH quieter now, which tells me the old lid had been leaking air for a long time.

I am very pleased with this chamber and the shipping was fast.

Thank you.
