Mounting alignment
• To avoid valve problems, all dirt, metal shavings, and
debris inside the piping must be removed or flushed out
prior to installing the valve.
• The preferred installation position of the valve and actuator
is upright. However, where space restrictions dictate, the
valve assembly can be mounted diagonally.
• The installation should account for an additional clearance
of 4 to 6” above the actuator. This space is needed for the
manual operation of the actuator. See "Actuator Manual
Operation" on page 4.
Warning
Motorized Valves MUST NOT be installed upside down or horizontally.
Warranty is void if valve installation position was installed incorrectly.

Valve actuator assembly
• For smaller valves, it is usually easier to assemble the
valve and actuator before the installation of the valve on
the pipe.
• For larger valves, install the valve in position prior to
installing the actuator to the valve.
• Thread and tighten the Valve Bushing to the valve.
• Remove the Actuator Brass Brackets. This should release
the Stem Attachment.
• Thread the Stem Attachment to the Valve Stem. Make
sure that it is tightened against the Stem Nut.
• Mount the Actuator on top of the Valve.
• Thread the Bushing Locknut to the Valve Bushing. Make
sure that the locknut’s beveled surface is facing the valve.
• Manually close or open the actuator to bring the Stem
Attachment to meet the bottom of the Actuator Shaft. See
"Actuator Manual Operation" on page 4.
• Join the Stem Attachment and the Actuator Shaft using
the Actuator Brass Bracket. Make sure the Actuator Brass
Bracket internal shape fits and locks Stem Attachment and
Actuator Shaft securely.
• For proper Actuator Brass Bracket operation, its
protrusions must be at the bottom (closer to the valve).
• Tighten the Actuator Brass Bracket screws and nuts using
the provided Hex Wrench.
