Tension
Adjustment
The glass door has an internal torsion bar, pretensioned at the factory, which
enables the door to self-close. If necessary, door tension can be adjusted by
rotating the capstan mounted in the bottom hinge bracket.
In the event the door tension can no longer be adjusted, the torsion bar may
need replacing (see “Torsion Bar Replacement” on page 57).

Replacement
The torsion bar assembly is located inside the door frame, and can be
replaced if necessary.
To replace the door torsion bar assembly
1. Slowly release tension on
the capstan, by turning the
capstan with a Ø2.5mm
steel rod, and removing
the split pin.
2. With the aid of another
Ø2.5mm steel rod,
increase the tension by
turning the capstan in the
direction the door closes.
3. Once adequate tension has been achieved, re-insert the split pin through the
hole in the hinge bracket to lock in position.
4. To check door tension, hold the door open approximately 100mm and let go
of the door. The door should gently close, with the door gasket forming an air
tight seal with the cabinet.

1. Disconnect the cabinet from the mains power supply.
2. Remove the door (see “Removal and Refitting” on page 58).
3. Carefully lever out the bottom bush from the door frame, and pull the old
torsion bar out from the door frame. The end of the torsion bar will need
manoeuvring to allow the ‘flat hook’ end to clear the hinge hole.
4. Remove the existing capstan and bush from the old torsion bar.
5. Thread the capstan,
complete with bush, over
the ‘round hook’ end of the
new torsion bar. Ensure
the aluminium tube moves
freely up and down the
torsion bar.
6. Fit the new torsion bar
assembly into the door
frame. When the torsion
bar is correctly installed,
the capstan should not
turn.
7. Lightly tap bottom of
capstan into hinge hole,
until the bush is flush with
door frame.
8. Refit the door to cabinet, and adjust tension (“Tension Adjustment” on
page 57).
