INSTALLATION GUIDELINES
The Overhead Storage Units are factory assembled and inspected. Tension of the
door mechanism is adjusted in
accordance with the size and the weight of the door.
1) Properly adjusted door mechanism will take over the weight of the door and lift
it as soon as the door bottom is
moved
about 3 1/2” - 4” above the bottom of the shelf. Should there be the need to fi ne
tune the door mechanism, proceed
as follows:
Check that the unit is properly installed and the assembly is square on the
extended cantilevers.
Remove internal covers by pushing two tabs (protruding through the bottom
shelf) up, then moving the bottom of the
internal cover away from the side wall.
2) To reduce tension, move springs on both sides of the unit onto the next pin,
closer to the central pivot point of the
door arm.
3) Similarly, to increase the tension, move the springs on both sides of the unit
onto the next pin, further away from
the central pivot point of the door arm.
4) Further adjustments may be done by disengaging springs from the arm, sliding
them forward into the larger opening
in the shelf and by re-inserting the spring again at longer or shorter position, as
required.
5) Set both springs with hooks pointing toward the back of the unit. Measure the
height of each spring to ensure
that both are exactly the same length (fi ne adjustments can be made by turning
the springs in or out).
IMPORTANT:
Spring adjustments must be done on both sides of the overhead to prevent the
door from twisting and jamming.
Check closing and opening door function as well as the door lock. Re-install the
inner covers and ensure that the
internal door mechanism arm is not rubbing covers’s sides.
