(7) Plumbing the hot, cold and fill-tub pipes
➀ Connect the pipes described so far to their respective connection ports on the function module.
➁ Open the shut-off valves on the hot and cold water supply lines and check to see that there are no leaks from the
joints.
➂ After connecting the cables and the bathtub equipment (Page 31), fill the tub and confirm that there is no water
leaking from the joints in the fill-tub pipes (two places: on the function module side and the bathtub side).
● Freezing prevention (Please implement this in locations where there is a risk of the equipment or pipes freezing.)
• To prevent freezing, insulation (insulating material, electric heaters, etc.) should be used that is appropriate to the
region.
• Insulate the plumbing completely after checking to see that there are no leaks from the hot, cold or fill-tube water
lines.
• In order to be able to drain water from inside the pipes, do not wrap the water removal valve with insulation.
Insulate so that
there is no gap.
