7.4 Door adjustment
Under normal circumstances, the chamber door does not require adjustments. However, if the
seal fails (resulting in steam leaking from the front of the chamber), you may use the spanner
tool to tighten the door seal.
7.4.1 Open the door.
7.4.2 Insert the spanner tool in the gap beneath the plastic cover. Use the spanner to grip the
adjusting nut (Fig. 1). Turn the nut counter clockwise as in the figure below (Fig. 2). This will
tighten the sealing plate.
7.4.3 Turn the nut until the sealing plate is tight. If the door knob is too tight, you may also turn
the nut clockwise to loosen it.
Caution: Never adjust the chamber door while the door is closed.
