INSTALLATION
Inspection
Inspect the package for damage. If package is damaged, notify the
appropriate carrier immediately. If undamaged, open the package and
inspect the device for obvious damage. Return damaged products.
Requirements
• Tools (not provided)
— Wrench 1 to 1-5/8" (if threaded valve)
— Soldering equipment (if sweat fit) or flare
• Training: Installer must be a qualified, experienced technician
• Other accessories as appropriate
Precautions
General
 W A R N I N G
• Electrical shock hazard! Disconnect power before installation to prevent
electrical shock or equipment damage.
• Make all connections in accordance with the electrical wiring diagram
and in accordance with national and local electrical codes. Use copper
conductors only.
• All conductors shall be provided with insulation rated for the highest
voltage motor and end switch circuits.
 C A U T I O N
• Avoid locations where excessive moisture, corrosive fumes, explosive
vapors, or vibration are present.
• Avoid electrical noise interference. Do not install near large conductors,
electrical machinery, or welding equipment.
• When making lead connections within the actuator, use caution not to
put leads or connectors below the motor.
Mounting
The valves can be mounted in horizontal or vertical piping. When installed
in horizontal piping, the actuator must be above the valve body. Refer to
Figure-5. When installed in horizontal piping the actuator can be tilted left
or right but it must not be tilted below 85° from vertical.
N O T E
• Make certain there is no overhead water source that may drip onto valve
actuator.
• In normal service, some condensation may occur on or around the
valve. A drip pan may be necessary or the valve body may be insulated.
Piping
These valves must be piped so the paddle closes against the direction of
flow. Flow is from B to A. Refer to Figure-6a to
Figure-6f. When installing the actuator to a normally closed valve, the
actuator must be placed in the manually open position by using the manual
operating lever. The first time the valve is operated electrically, the manual
operating lever of the actuator will transfer to the automatic position. The
manual operating lever can be used to allow flushing of the system after
installation. The valves are designed for application in closed hydronic
heating and cooling systems. High levels of dissolved oxygen and chlorine
found in open systems may attack the valve materials and result in
premature failure. Install over a drip pan if condensation in chilled water
applications occurs.
 C A U T I O N
Use in systems which have substantial make-up water (open systems) is
not recommended. Follow proper water treatment practices and system
procedures. Refer to document F-26080-1 for Water and Steam EN205
Guidelines.
N O T E
• Three-way valves always require a normally closed actuator.
• Three-way valves are always closed at the B port when no power is
applied to the motor.
• On power-up the valve closes to A port on three-way valves.
• Orient the three-way valve body as needed for normally open or
normally closed flow through coil.
