Remark:
1. For the first time use, ensure the water tank have been filled with water before power on to prevent
burn out. Meanwhile, the circulation water pipe should be filled with water, no air left inside. Checking
the pipe to ensure the water circulates successfully.

and drainage pipe interface. Among them, the water supply pipe and hot water outlet pipe should be
used in line with standards for drinking water pipes. (E.g. PPR pipe or stainless steel pipe, etc.), can
not use iron pipe or the rubber hose with odor for installation.
