WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid state
speed control devices.
Disrupt power at circuit breaker to outlets within the stud wall you will be working.
When sawing through sheetrock you must stop if you detect the saw blade coming in contact with any wiring
or plumbing. Investigate further to determine if it is possible to safely continue to use this wall cavity space.
Switch to another stud wall cavity if necessary.
BEFORE YOU START:
Determine the stud wall section that you want to use to mount the Blower and Diffuser. You must select a
stud wall section that contains an electrical outlet, (See Diagram A). IMPORTANT: Wall studs must be
spaced a minimum of 16” o.c., (See Diagram B). Mark inside edges of studs the Aireshare
TM will be
installed between and verify there is at least 14” between the inside edges. Slide a stud finder down the wall
between the studs to verify the stud wall cavity is completely open, (See Diagram C).
TOOLS REQUIRED
Sheetrock Saw Philips & Straight Screwdrivers Level Tape Measure Utility Knife or Scissors
INSTALLING DISCHARGE DIFFUSER
IMPORTANT: Install Diffuser first if mounting the Blower down low and the Diffuser high so sheetrock from the
Diffuser cut out does not fall into wall cavity and damage Blower. Install the Blower first if mounting the Blower high
and Diffuser low so sheetrock from the Blower cut out does not fall into wall cavity and damage Diffuser.
NOTE: Since electrical outlets are usually not up high, typical installations of the model AS1P will have the Diffuser
high and the Blower low, but there may be instances where it is desireable to have the Blower mounted
high and the Diffuser low to take air from the ceiling level.
1.The Diffuser may be mounted as close as 3" above the top of Blower cut out opening or as close as 3" to the ceiling.
2. Level and mark a line between studs for top of the Diffuser cut out, (See Diagram D)
3. Using a hand sheetrock saw carefully make a horizontal cut along the line. Cut the sheetrock completely until you
come in contact with the opposite stud. NOTE: If studs are spaced greater than 16” o.c., the horizontal cut line
should not exceed 14”, (See Diagram E).
