ADJUSTING DOOR TENSION
1.
Check that each EcoVision door opens and
closes properly. The door’s closing speed may
be adjusted by rotating the adjustable tension
rods near the hinge of each door.
2.
Use a ½ inch wrench to adjust torsion rod.
To increase tension, turn wrench toward the
door handle until torsion rod seats in bottom
hinge plage assembly. An audible “click” is
heard while adjusting. Generally, the torsion
rod should be adjusted to 4 or 5 clicks. The
maximum amount of clicks is 6. Do not over-
torque. See next step if the wrench can not be
put on the torsion rod because of interference
with the contour / rectangular end.
3.
Do not over-torque the hinge spring assembly.
Lift door up and out of bottom hinge plate to
remove door tension. Do not use wrench to
decrease door tension as this may damage the
star pattern on the bottom hinge plate assembly.
Door must be properly
seated inside bottom
hinge plate after door
tension is applied.
