- INSTALLATION
- . Electrical shock hazard! Disconnect power before installation to prevent electrical shock or equipment damage.
- . Avoid locations where excessive moisture, corrosive fumes, explosive vapors, or vibration are present.
- . When making lead connections within the actuator, use caution not to put leads or connectors below the motor.
- This is a class B (European Classification) product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.
- 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.
- Do not solder with actuator in place, or with paddle against seat, as the heat can damage the unit. Before soldering, move the manual open lever into Open position then remove the actuator from the body. Orient paddle so it is not against a seat.
- Do not use the valve body to manually open the actuator as damage to the valve actuator will result.
- CHECKOUT
- 1. Make sure the valve stem rotates freely before and after installing the actuator.
- 2. If the stem does not operate freely it may indicate that the stem was damaged and may require that the valve be repaired or replaced.
- 3. After the piping is under pressure, check the valve body and the connections for leaks.
- 4. After the valve and actuator are installed, power the actuator and check the operation.

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.
