2.8.2 Requirements on Installation
(1) The water valve should be installed as the following statement; otherwise it would affect the normal
operation.
It is not allowed to directly insulate the connection line
of the actuator and the water pipe together, otherwise it
would lead to shortcutting of the water valve which would
affect its service life.
Water pipe
Never install the valve downwards, otherwise the
condensate would flow into the valve and damage the
valve or then would lead to shortcutting or fire hazards.
(2) There are direct pass and bypass for the water valve and they can be selected based on actual
conditions. See the figure below for the working principle for the water valve.

Water pipe
The main body of the valve should be
installed upwards and the power lines should be
