Drain the Chamber
!
CAUTION
►
Disconnect the plasma thawer from AC power before draining the chamber.
►
Do not move the plasma thawer when the chamber is filled or if the plasma thawer is
connected to AC power.
The plasma thawer has a drain port to drain water from the chamber. The drain valve is integrated into
the drain fitting on the side of the plasma thawer. The drain valve remains closed until the drain tube is
connected to the valve. When the drain tube is connected, the chamber begins to drain immediately.
The drain coupling must be installed on the drain tube before the drain tube can be connected to the drain
valve. The 90º elbow may be installed in the drain tube to facilitate convenient routing of the drain tube.
Left: Drain port with coupling valve and drain tube connected (release button identified with arrow).
Middle: Drain tube with coupling valve installed. Right: 90° elbow fitting.
Drain water from the chamber:
