Notes
(a) Distance between indoor unit and water tank should not exceed 5m levelly and 3m vertically. If higher,
please contact with us. Water tank on lower and main unit on higher side is recommended.
(b) Prepare the materials according to the above joints dimension. If cut-o valve is installed outside the room,
PPR pipe is recommended to avoid freeze damage.
(c) Waterway pipelines can’t be installed until water heater unit is xed. Do not let dust and other sundries
enter into pipeline system during installation of connection pipes.
(d) After connection of all waterway pipelines, perform leakage test rstly. After that, perform heat preservation
of waterway system; meanwhile, pay more attention to valves and pipe joints. Ensure enough thickness of
insulated cotton. If necessary, install heating device for pipeline to prevent the pipeline from freezing.
(e) Hot water supplied from insulated water tank depends on pressure of water tap, so there must be supply of
tap water.
(f) During using, the cut-o valve of cooling water inlet of water tank should be kept normally on.
