Door
The door is mounted on a special anchor plate
which sits on the machine’s outer drum. The door
glass is fitted in the door with only a door seal
which also is tightly fit directly against the outer
drum when the door is closed. The glass is not
glued-coated making it easy to replace.

Door seal leakage

If the seal is not torn or damaged in some other
way, the cause of the leakage could be decreased
elasticity of the seal. Place a 4-7 mm sized O-ring
around the entire seal in the seal slit (see
illustration).
If the leakage persists, change the seal.
Safety lock
The safety lock is mounted on a circuit card with a
contact for quick connection. The following is on the
circuit card:
• the lock plate against which the safety lock knob
locks the door.
• the microswitch which indicates that the door is
closed.
• a lock unit which keeps the door from opening
when the machine is in operation. This unit
consists of:
- a double functioning solenoid
- a delay unit with a bimetal spring
- a lock bolt which can be controlled by both
the solenoid and the delay unit.
- a catch which keeps the lock bolt from locking
when the door is open. The catch also
controls a microswitch.
