ESBE 3-WAY VALVE
INSTALLATION INSTRUCTIONS
Pipe the Valve into the System
• ESBE 3-way valves can be piped for either 3-way Mixing or 3-way Diverting applications
• 3-way Mixing: 2 inputs, 1 output • 3-way Diverting: 1 input, 2 outputs
• The System port, or the port on the valve which will deliver the mixed water to the
system, must never be the center port.
• Install the valve so the actuator (if so equipped) will not be below the valve (ie.
facing the floor).
Orient the Valve Face Plate
• The face plate can be turned over and rotated to match your piping configuration.

Art.nr. 98140081 Ritn.nr 3285 Utg PC6
Wiring: 91M, 92M, 92-2M and 93M for “Floating” Signals (see ). For ESBE
92P and 92K2 actuators, refer to the actuator’s installation instructions.
Warning: Always turn off all electrical power before removing or servicing
the actuator.
– The actuator is powered using a 24VAC transformer, 3VA minimum.
– Remove the four cover screws and lift the cover off the actuator.
– Remove one (or two) of the wiring knockouts and install one (or two) of the
“conduit fittings”. All wires must go through these fittings.
– Attach the “common” from the control (or transformer) to terminal “N”.
– Connect the control output for clockwise rotation to “Upper terminal L1”, and
connect the control output for counterclockwise rotation to “Lower terminal L1”
Auxiliary Switch
–ESBE 91M, 92M, 92-2M and 93M actuators include one fully adjustable
auxiliary switch. The wiring should be connected as shown in . To set the
switching position, turn the cam (see ).
Reinstall the cover and secure it, before turning on the power.
Adjusting the Degree of Rotation
– ESBE 90 series actuators do not require adjustment when used with ESBE
valves. However if the actuator is used for an application that requires a differ-
ent degree of rotation, the middle and lower cams can be adjusted to provide
between 30° and 180° of rotation. For access to the cams, the cam operating the
aux switch must be removed. See . Always turn off all power before adjust-
ments are made.
Test: Test the valve rotation to ensure the valve is allowed to fully open and
fully close. Rotations of 30° to 180° are possible via middle and lower cams for
applications that require them. For access, aux. switch cam must be removed.
