9. Water Circulation
Check water pipe is correctly connected, if not so, the
unit can not work normally.
9.1 Check Water Circulation
(1) Water module is connected to water
circulation system through water inlet and outlet.
This water circulation system must be installed by
qualified plumber in accordance with relevant
national regulations.
(2) Water module is only applicable to closed water
system. When applied to opened water system,
water pipe may be corroded.
(3) Check before water module installation:

than 0.3Mpa. If make-up water pressure on site is
more than 0.3Mpa, recommend reducing valve or
automatic make-up valve is mounted on site.

water module discharges air normally and whether
the sound of quick venting occurs. If vent valve
leaks water or is damaged, contact local dealer.
