You must read the instructions carefully before installation, cut off power and must be installed by a professional technician.

The direction of flow must be identical to the direction of the arrow on the valve body.

Valves shall be located above the coil drain pan, to ensure that when there is a drop into the water pan.

Valve body and drives must be installed in a vertical direction ± 60 ° c range, the top should be at least 30mm space for Assembly and disassembly. And around the pipe, equipment, building maintenance operations must maintain sufficient space, maintenance personnel must be installed through a manhole can reach places.

Installed valve body and piping system by pressure test before I can install the drive.

If the drive is already mounted to the valve body, you must not drive during the installation process the force, otherwise you will damage the drive.

And check for correct installation, power on debugging. Should be observed at least three full cycles of the drive, make sure all parts correctly.

When they passed waterless debugging, and water testing. System water pressure within 0.15MPa must be strictly controlled in order to ensure the efficiency of electric regulating valve on the flow switch.
