1.3  Disposing of the Cabinet 

 

 DANGER

 

• 

TRAPPED INSIDE! Before disposing of the cabinet, 
take the door off its hinges. 

• 

HEAVY DOOR! Have someone hold the door when 
detaching it from the hinges. 

The door is heavy and can injure you if it falls on top of you. 

 

 

1.  Remove the bolts that lock the hinges (x 2) to the door. Use an 8 mm 

wrench. Support the door to prevent it from falling. 

 

 

2.  Lift the door upward slightly and then pull it toward you to detach.
