(5) When the water pipe and water valve have been installed, connect the connection line of the valve
to the wiring board of the unit.

Notices:
(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.

Never install the valve downwards, otherwise the
condensate would ow into the valve and damage
the valve or then would lead to shortcutting or re
hazards.
The main body of the valve should be
installed upwards and the power lines should
be arranged above the water pipe.
Insulation sponge
Do not cover fully the valve with the
insulation sponge; otherwise it would
lead to poor heat radiation and even
re hazards.
