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 dam-
age. Return damaged products.
Requirements
Tools (not provided)
• Wrench 1 to 1-5/8” (25 to 40 mm)
• Pipe wrench according to pipe size
• Volt-ohm multimeter
Training — Installer must be a qualified, experienced techni-
cian
Other accessories as appropriate
Notice:
• 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.
• 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.
• The use in systems which have substantial make-
up water (open systems) is not recommended.
Follow proper water treatment practices and system
procedures.
Mounting
The valves can be mounted in horizontal or vertical piping.
When installed in horizontal piping, the actuator must be
above the valve body. It can be tilted left or right but it must
not be tilted below 90° from vertical.
Horizontal Plane
90˚
Horizontal Pipe
360°
Vertical Pipe
Piping
These valves must be piped according to the water flow
directions as below and marked on the valve. Two-Way valve
flow should go A to AB. Three-Way valves should only be ap-
plied as mixing valves (see diagram).

* Two-Way valve operation described. For a Three-Way valve, A to AB operation is the same. B to AB operation is opposite that of A to AB
operation.
Installation Notes
• Ensure 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.
• Do not cover the actuator or obstruct the manual
operator lever.
• Reference product label and Product Datasheet EN-03-
000237-xx-EN for additional product specifications.

Installing the Valve Body
Apply PTFE tape to the male pipe thread. Hand screw the
pipe into the valve, turning it as far as it will go. Use a wrench
to fully tighten the valve to the pipe. Do not over tighten or
strip the threads.
Installing the Actuator on the Valve Body
1. Turn the valve stem so that the slot on the top of the
stem is pointing towards the large keyed post. (See im-
age above)
2. Insert the hex key into the slot on the top of the actuator.
Rotate eight full revolutions. In the last turn, align the in-
dicator notch to the opening in the manual cranckshaft.
Press the lock button around manual crankshaft to lock
in place. Remove and replace hex key in cover slot.
3. Align the valve body with the actuator to ensure the stem
lines up with the large stem hole and the large keyed
post lines up with the post hole on the bottom of the
actuator.
4. Press the valve and actuator firmly together to lock into
place.
5. The first time the valve is operated electrically, the man-
ual crankshaft of the actuator will move to the automatic
position. The manual crankshaft can be used to allow
flushing of the system after installation.
Removing the Actuator
6. Press and hold the valve release lever inward, towards
the valve.
7. Lift the actuator from the valve.
Notice
• Do not use the valve body to manually open the actuator
as damage to the valve actuator will result.
Checkout
8. Make sure the valve stem rotates freely before and after
installing the actuator.
9. If the stem does not operate freely it may indicate that
the stem was damaged and may require that the valve
be replaced.
10. After the piping is under pressure, check the valve body
and the connections for leaks.
11. After the valve and actuator are installed, power the
actuator and check the operation by varying the control
signal. On spring return models, the valve should return
to its normal position when power is removed.
Manual Override
The manual override lever is designed to manually position
the actuator to install on the valve or to manually position the
valve. Turning the hex key in the manual crankshaft while
power is applied or in the opposite direction as shown on the
label will cause permanent damage. Use only the hex key
provided with a maximum torque of 1.3 Nm (10 in/lb).
Notice
• Do not use the manual operator while power is applied
to the actuator. Manual positioning of the actuator while
power is applied is NOT recommended.
Theory of Operation
When powered, the actuator moves to the desired position,
tensing the spring return system. When power is removed
the actuator returns to the normal position.
Maintenance
The ball valve assembly itself requires no maintenance. The
stem and packing design eliminates the need for packing
adjustment for the life of the valve. However, regular mainte-
nance of the total heating and cooling system is recom-
mended to ensure sustained optimum performance.
Field Repair
Neither valve nor actuator are field repairable. Replace
entire unit as necessary.
