  • Page 26 3) Transportation To move or lift the unit, attach ropes to the hoisting hangers (4 pieces) available on the edge of the unit. Apply protector or support to avoid the ropes direct contact with coil and panel as shown in the diagram. 4) Water Piping a) Air vent must be installed at the highest position.
  • Page 27 c) Install an expansion tank at the highest position as shown in the diagram. The capacity of the expansion tank is 0.03~0.034 of the water volume. d) Install 60 mesh Strainer to ensure the water quality is good. e) Ensure the flow switch is installed and function properly. f) Ensure all water pipes are well insulated g) Fill up water after water piping work complete.
