Instructions for Operation and Use
1. Assembly and disassembly of the actuator and valve body fit the
square axis of the valve body with the square hole in the actuator and
insert (make sure that another axis will not touch the actuator). Rotate
the actuator or valve body and make another axis of the valve body aim
at the corresponding hole in the actuator. Use a small amount of force to
press the actuator. Turn the key clockwise to lock the actuator into place.
The assembly of the actuator and valve body is finished. When
disassembling, turn the locking key counter clockwise, and use a little
force to pull out the actuator in the opposite direction used for assembly.
2. 3-way valve installed (Figure 2 and 3). For high building, the
pressure–reducing valve should be installed on branch pipe at ground
floor.
3. Note: When the valve is mounted on a horizontal pipe, the angle must
be positioned at less than 85° (see Figure 4). When the valve is mounted
on a vertical pipe, it must also be prevented from dripping.
4. Manual operating lever: The valve is unlocked when you press the
manual operating button. Moving the manual lever can make the valve
return. When releasing the button, the valve will be locked again
automatically.
5. When installing 3-way valve, end “B” supplies to the coil, end “A” is by-
pass, there is no mark for inlet, end “A” and “B” are marked on the
bottom of the valve body.

should not be attempted and may void warranty). Be sure to include a
