See the figure above for installation of the water valve. Firstly, connect one end of the water pipe to
the water inlet of the unit, and then connect the other end to water valve. During installation, both the
torque wrench and ordinary wrench should be used. For the former, the torque should be less than
90N.m.
(2)
The pipe connectors and the water valve are G3/4 threaded. In order for better sealing effect, before
connection they should be wrapped with Teflon tape.
(3)
After the connector, the water valve and the water pipes have been finished, start the water pump and
see if they leak or not.
(4)
Insulate the water valve and the pipe with sponge.
