8.  The spring (left) is already in the pocket on the top left corner of the door.  

Important  -  The straight end of the spring will need to be inserted into a small 

hole in the bottom of the pocket so when it is rotated it has tension.   

9.  Install the Top shaft taken out from the right side to the top left pocket/spring and 

insert the straight end of the spring into the small hole at the bottom of the hinge 

shaft collar. Insert the Top Hinge Plate onto  the Hinge Shaft.  The Top Hinge 

Plate should be at a 90 degree angle to the door and sticking out to the front of 

the door when the spring is relaxed. 

10. Place the Door on the cabinet by inserting the pin on the Bottom Hinge into the 

Bushing placed into the bottom of the Door in step 7. 

11. To apply tension to the spring, wind the Top Hinge clockwise 180 degrees and 

use the screws removed in step 3 to attach the Top Hinge Plate to the cabinet. 

Note that the Top Hinge Plate can rotate due to the tension of the spring.   Work 

carefully. 

12. Check the Door to confirm the self-closing feature is operating properly.  Adjust 

spring tension as required. 

13. Wait one hour before re-connecting the unit to power.
