This user manual outlines important safety precautions such as using a dedicated fuse‑protected power line, proper grounding, and maintaining clearances around the indoor and outdoor units. Detailed installation instructions cover mounting height, clearance distances, and wiring requirements.
The guide explains how to operate the unit using the controller keys, including temperature adjustment, mode selection, fan speed, timer, and sleep functions. It also includes maintenance tips, troubleshooting advice, and a full specification table for the AT-116ZM model. This manual is written in Chinese.
Use a dedicated fuse‑protected power line, ensure the grounding wire is connected first, keep at least 50 cm clearance for intake and exhaust openings, and avoid installing in humid or dusty indoor locations.
Press the temperature up or down key; each press changes the set temperature by 1 °C, with a range from 16 °C to 30 °C.
The compressor will stop for three minutes after a mode change or when the unit is turned off, then automatically restarts to protect the system.
Check that the power plug is secure, the fuse is intact, the filter is clean, the temperature is set correctly, and that there are no obstructions at the indoor or outdoor vents.
