FIGURE 2 - Standard Wall Mounting

If the wall mounting plate must be mounted higher than 4" above

the door opening, it must be spaced out from the wall

every additional inch (over 4") that the unit is above the door

opening. See Figure 3

For optimum protection, do not exceed the recommended maxi-

mum mounting height of 8' above the finished floor. Any void

between the mounting plate and the wall should be sealed along

the full length of the mounting plate.

E. Determine which of the four holes provided in each of the steel

brackets of the wall mounting plate are located where suitable

support is available for the unit. Minimum one inside hole and

one outside hole from each bracket must be used for proper

support. Drill out the aluminum backing of the holes chosen with

a ¼" drill bit. If the provided holes on the mounting plate are not

located where suitable support is available, drill new holes in the

space provided on the steel mounting brackets.

F. Mark the wall in the centers of the ¼" holes drilled on the mount-

ing plate.

G. Attach the mounting plate to the wall (hardware by others).

H. The top of the unit is provided with two knockouts on each side

allowing for a left or right hand power connection. Remove the

wiring tray cover; on units that are comprised of modules, re-

move the wiring tray cover that is located closest to the electrical

rating nameplate. Remove the required knockouts and attach

necessary electrical hardware. Save the wiring diagram found

inside of wiring tray. See Figure 7

I. There are two sets of keyhole slots on the wall mounting plate.

In low overhead installations the air door may be staged in the

lower keyholes to provide clearance for electrical wiring and

then moved to the higher holes after completion. Raise the air

door with the discharge opening facing down toward the floor.

While holding the unit level, slide the heads of the shoulder

bolts into the larger hole of the keyhole slots of the mounting

plate. Lower the unit into place, keeping both ends level, allow-

ing it to rest flush with the mounting plate. See Figure 4

J. After attaching the unit to the mounting plate, ensure that the

unit is seated and flush with the mounting plate on all four sides.

K. Proceed to Section V - Electrical Connections.
