ES40H-T1(E) ES50H-T1(E) ES60H-T1(E) ES80H-T1(E) Product manual
The manual begins with safety warnings and warranty information, emphasizing the need for a grounded power source, a dedicated socket, and the importance of regular maintenance such as magnesium rod replacement. It also outlines Haier’s “1+5” service commitment and contact details for after‑sales support.
Installation instructions require authorized Haier service personnel to mount the unit, connect water lines, and seal connections with thread‑seal tape. Subsequent sections describe how to operate the heater, adjust temperature and flow, use the scheduling and night‑tariff modes, and perform cleaning, troubleshooting, and part replacement. This manual is written in Chinese.

Installation must be performed by Haier’s authorized service personnel or their designated installers, following the step‑by‑step procedure that includes securing the unit, connecting the safety valve, flow sensor, and water pipes, and sealing with thread‑seal tape.
Use a grounded power source with a dedicated, certified socket, avoid connecting the ground and neutral together, keep the unit away from water splashes, and ensure the water pressure is within 0.05 MPa to 0.7 MPa.
Turn off power, drain the tank, remove the heating tube cover, clean with neutral detergent, and replace the magnesium rod every two years or when its performance declines.
