PRE-INSTALLATION

Inspection
Inspect the package for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
package and inspect the device for obvious damage due to
shipping. Return damaged products.
Required Installation Items
•
Wiring diagrams
•
Tools (not provided):
Digital volt-ohm meter (DVM)
Appropriate drill and drill bit for mounting screws
Appropriate wrenches for adjustment of damper and
valve linkages
TOOL-209, 135 ohm slidewire and 0 to 7 mA manual
positioner
•
Appropriate accessories

INSTALLATION
Caution:
1. Installer must be a qualified, experienced technician.
2. Disconnect power supply before installation to prevent
electrical shock and equipment damage.
3. Make all connections in accordance with electrical wiring
diagram, and in compliance with national and local codes.
Use copper conductors only.
4. Do not exceed the ratings of the device.
5. Avoid locations where excessive moisture, corrosive
fumes or vibration are present. NEMA Type 1 housings
are intended for indoor use primarily to provide a degree
of production against contact with enclosed equipment.

Mounting
The actuator can be mounted in any position in a weather
protected area. It is recommended that valve actuators be
mounted above the centerline of the valve body. When
selecting a location, allow sufficient room for accessories and
for service of the product.
MS-8301X Valve Actuators
For the correct installation of valve linkages refer to the
instruction sheets for AV-430 (F-19072) or AV-495 (F-21665)
which-ever is appropriate for the particular valve body.
