Fig. 3. Mount sail switch in one of the positions shown
for angle-t junction ductwork. Transition in trunk is
recommended.
NOTE: When the S688 is mounted in warm air, the sail life
may be reduced.
Refer to Figures 1-3 for the best duct mounting location.
Mount the switch at least 6 in. (152 mm) upstream from an
elbow or junction, and at least 15 in. (381 mm.)
downstream from an elbow or junction. The switch must be
located on the opposite side of the duct from the air
entrance.
ADAPT SWITCH TO AIR FLOW DIRECTION
The S688A Sail Switch is provided with two
counterbalancing springs in place as shown in Fig. 4.
These springs offset the effect of gravity for air flow
direction.
