Installation and usage instructions

The installation of normally closed two-way valves and diversion three-way valves is shown in Figure 1, Figure 2, and Figure 3. For high-rise buildings, pressure reducing valves should be installed on the bottom branch pipes.

Attention: The motor cover should prevent water from seeping in. When the valve is installed in a horizontal pipeline, the angle between the installation position and the vertical plane should not exceed 85 ° (see Figure 4). When the valve is on a vertical pipeline, the motor casing should prevent water from seeping in.

Manual operating lever: When the manual lever is slowly moved in the direction of the arrow and pressed into the notch, the valve is in a normally open state. Whenever the current first passes through the electric valve, the manual lever returns to the automatic position.

If the driver is not pre installed on the valve body and needs to be installed, first push the operating rod of the driver into the groove in the direction of the arrow, press the black button next to the driver, place it on the valve body, and then release it to install it. If disassembly is required, repeat the above steps.

Attention: The direction of water flow should be consistent with the arrow on the valve body; During installation, the drive should not be used as a fulcrum for stress.
