AB-6594 Installation CAUTION Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards. Install the product in the proper position as specified in this manual. Excessively tight connection to a pipe or improper installation position might damage the product. After installation, make sure no fluid leaks from the valve-pipe connections. -
Page 6: Heat Insulation
AB-6594 Piping ● Install a bypass pipe and gate valves on the inflow, outflow, and bypass sides. Also, install a strainer (with 40 or more meshes) on the inflow side. ● When installing the valve to pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve cannot fully closes, or the valve seat may get damaged causing fluid leakage, due to an foreign object jammed inside the valve. - Page 7 AB-6594 Assembling the valve Model VY5302A with the actuator Model MY53X0A IMPORTANT: The actuator can be horizontally rotated every 90 degrees to fit into the valve mounting position (4 mounting positions). Make sure the positions of the actuator and the valve as follows, referring to Fig. 8: - Actuator: Indicator/manual lever points at 100 (fully open position).
