Installing the Pressure Switch

IMPORTANT
Do not install the switch in an area where temperature exceeds rating of
-40°F to 190°F (-40°C to 88°C).
1. Disconnect power from the humidifier before
installing.
2. Mount the switch vertically with pressure
connectors facing down, using provided self-
tapping screws to secure the switch to the duct.
3. Cut 3/4-in. (19 mm) diameter holes in the
supply and return ducts within 10 feet of the
switch to ensure the provided tubing reaches the
pressure tap elbows. See Fig. 9.
4. Insert the black rubber gaskets into the duct
holes.
5. Connect the tubing to the tubing fitting elbows
and insert the tubing fitting elbows into the
black rubber gaskets in each duct.
6. Connect the other end of the tubing to the
applicable pressure connection on the switch.
a. Connect supply duct tubing to the +
connection.
b. Connect return duct tubing to the –
connection
7. You may cut the tubing to fit the connection
length between the elbow fitting and switch. It is
also recommended to secure the hose to
existing structures to avoid accidental
disconnection.
