APPLICATION
For applications where an electrical circuit is used to
control a pneumatically-operated device. Used to direct
supply air to a pneumatic device when the coil is
energized or de-energized, depending on the supply
and exhaust air connects.
FEATURES
• Open frame or junction box construction
accommodates a wide variety of NEMA 1 mounting
locations.
AL-170 Series
AL-180 Series
Solenoid Air Valves

ACCESSORIES None
When power is supplied to the exhaust fan, the fan runs, and the solenoid air valve is
energized, closing port 2 and passing main air from port 1 through port 3 to damper actuator,
which opens the normally-closed exhaust damper.
When power is removed from the fan, the fan stops, and the solenoid air valve is deenergized, closing port 1 and bleeding air from the damper actuator through port 3 and out
port 2 to atmosphere, closing the exhaust damper.

INSTALLATION
Inspection
Inspect the carton for damage. If damaged, notify the appropriate carrier immediately.
Inspect the device for obvious damage. Return damaged products.
Requirements
• Job wiring diagrams
• Tools (not provided)
• Training:
Installer must be a qualified experienced technician.
Warning:
shock and equipment damage.
Caution:
with national and local electrical codes.
Do not exceed ratings of the devices.
Avoid locations where excessive moisture, corrosive fumes, or vibration is present.
Disconnect the power supply (line power) before installation to prevent electrical
Make all connections in accordance with the wiring diagram and in accordance
Mounting Remote Mounting
Warning:
plate is provided.
1. Fasten to wall or duct with two #8 sheet metal screws or equivalent.
2. Rotate the solenoid enclosure to position the wiring compartment, if necessary.
Warning:
This method requires the use of the enclosure on the coil. An integral mounting
Do not over-tighten as this may cause distortion of plunger tube or damage coil.
CHECKOUT
Go, No Go Test
1. Connect solenoid ports to plastic tubing.
2. Apply air to port 3. Ports 3 and 2 should be connected.
3. Apply power to the solenoid. Ports 3 and 1 should be connected.
4. If ports 3 and 1 are not connected, check to see if the proper voltage is applied.
5. Replace the solenoid with a functional unit if solenoid is powered and ports 3 and 1 are
not connected.
Use copper conductors only.
MAINTENANCE
Regular maintenance of the total system is recommended to assure sustained optimum
performance.
FIELD REPAIR
None. Replace with a functional solenoid.
