Instructions for Operation
Normally-closed 2-way and diverting 3-way valve are installed as Figure 1, 2 and 3 shows. For high building, pressure –reducing valves should be installed on branch pipes at ground floor.

Manual operating lever: Move the manual operating lever slowly and hold in the retaining notch, and then the valve is in normalopened position. When the valve is first powered on, the lever goes back to the automatic position again.


When installing a diverting 3-way valve, end “B” is the supply to the coil, end “A” is the by-pass. There is no mark for an inlet. End “A” and “B” are marked on the bottom of the valve.

When the valve has an auxiliary micro switch, the wiring diagramis as follows:

Upon final installation of the Series 3ZV1 Three-Way Zone Valves,no routine maintenance is required. A periodic check of the system calibration is recommended. The Series 3ZV1 is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return good authorization number before shipping.
