PREPARATION OF THE STRUCTURE: FLAT, LEVEL, PLUMB, AND SQUARE
***** THE UNIT WILL NOT OPERATE PROPERLY UNLESS IT IS FLAT, LEVEL, PLUMB, AND SQUARE *****
i.
For Recessed Mount Applications, ensure that:
(a)
FLAT & LEVEL:
a.
The base surface of the header to which the canister back will be secured is flat and
level; and
b.
The floor/base is flat and level; (the bottom weight bar is equipped with a brush pile
seal which is designed to conceal minor variations in the floor/base surface in
addition to impeding incursions by bugs; and
c.
Take 3 measurements from header to floor/base; left, middle, and right. They
should be identical otherwise you may have to use shims; and
(b)
PLUMB:
a.
Take 3 measurements from side jamb to side jamb; top, center, bottom. They
should be identical otherwise you may have to use shims; and
b.
Using a level or plumb line ensure that the side jambs are plumb; and
(c)
SQUARE:
Measure the two diagonals: top left to bottom right corners; top right to bottom left
corners. The measurements should be identical.
ii.
For Surface Mount Applications, ensure that:
(a)
FLAT & LEVEL:
a.
Using a laser line or level on the header, pencil in a line at the height at which the
top of the canister will be located; and
b.
Check the floor/base to ensure that it is flat and level; (the bottom weight bar is
equipped with a brush pile seal which is designed to conceal minor variations in the
floor/base surface in addition to impeding incursions by bugs; and
(b)
PLUMB:
Using a laser line or level on each side jamb, pencil in a line at the width at which the
outer edge of the side rails will be located; and
(c)
SQUARE:
Measure the two diagonals: top left to bottom right corners; top right to bottom left
corners. The measurements should be identical.

INSTALL THE CANISTER
**** Depending on the size of the unit, 2 persons may be needed for this step of the installation ****
Identify the location where the electrical cord will be located. Drill a 5/8” diameter hole on the canister
in the location where the electrical cord will exit the canister. The 5/8” diameter hole should be near to
the end of the canister with the U-bracket that receives the motor. Drill any additional holes needed in
the jamb structure through which the electrical cord will be passed to reach the circuit.
i.
For Recessed Mount Applications: Secure the top of the canister to the underside of the
header jamb.
ii.
For Surface Mount Applications: Secure the back of the canister to the surface of the
header jamb with the top edge along the line drawn in Instruction 6 ii. (a)
For units under 12’ wide use 2 fasteners positioned 1’ from each end of the canister. For units over 12’
wide use a 3
rd
fastener in the center. Use a washer on each fastener if necessary.
