ifier drain fitting and run to the floor drain (see Fig.
10).

b. Push the tubing over the drain nipple on the
humidifier.
c. Hand-tighten the clamp around the tubing to
secure the humidifier drain.

along the route to prevent movement and
ensure downward slope for correct drainage.
NOTE: Cut tubing to correct length so the tubing termi-
nates at the drain.

Installing the Sail Switch
Adapting Switch to Air Flow Direction
The S688A Sail Switch has two counterbalancing springs
in place as shown in Fig 11. These springs offset the
effect of gravity for air flow direction.
IMPORTANT
Do not use the sail switch with both springs
attached. Be sure to select air flow direction and
remove spring(s) not required for installation.
Fig. 11. Adapting sail switch to air flow direction or
mounting position.
• Vertical downward air flow: Leave the spring in
place that is attached to the bracket marked Down.
Remove the spring that is attached to the bracket
marked Up.
• Vertical upward air flow: Leave the spring in place
that is attached to the bracket marked Up. Remove
the spring that is attached to the bracket marked
Down.
• Horizontal air flow: Remove both springs.
1. Mount the template (provided with the sail switch)
at the desired location.
NOTE: Be sure the arrow (indicating air flow) points in
the correct direction.
a. For horizontal mounting, level the long dimen-
sion shown on the template.
b. For vertical mounting, plumb the long dimen-
sion.
2. Cut the hole (indicated on the template) in the duct-
work.
3. Center punch the screw holes indicated and drill
out with a 1/8 in. (13 mm) drill.
