3. If the blower is on, turn it off, and turn off other noise producing equipment
nearby. This step involves listening for a click from each switch. Check each
switch function by slowly raising and lowering the sash. Check each switch to
see if an audible click is heard when the sash is at key positions:
a. CLOSED
– close (lower) the sash, and within 1 inch (25 mm) of fully
closed, an audible click is heard from the CLOSED switch shown in Figure
12-4.
b. (If a Type C1 or A2 12-inch sash model) ALMOST CLOSED
– from the
fully closed position, raise the sash slowly until the CLOSED switch
disengages (first click), and within 2 inches (50 mm) of upward travel a
second click should be heard from the ALMOST CLOSED switch.
c. OPERATING POSITION 1
– continue raising the sash slowly from closed,
and when the bottom edge of the sash glass is within 1 inch (25 mm) of
the sash height decal on the left corner post, a click is heard from the
OPERATING POSITION 1 switch shown in Figure 12-4.
d. (If a Type C1 model)
– OPERATING POSITION 2 – continue raising the
sash past the 8-inch operating sash position, and when within 1 inch (25
mm) of the 10-inch operating position, a click is heard from the
OPERATING POSITION 2 switch. This switch is only found on Type C1
models, and corresponds to the 10-inch operating sash height position.
