Instruction of operation and Installation
1.Feed line and return pipe of differential pressure should be controlled within the range allowed pressure difference.
2.The valve should be installed somewhere easy to install and maintain.
3.Horizontal installation, that’s mean the motor should be in the above of valve body to avoid humidity.
4.When install 3 way valve, infall is on the bottom of valve (no signal showed)
