Intelligent error indication
If an E1, E2, E4, or E5 error appears on the LED display, turn off your air conditioner and call a professional maintenance
technician or service center.
Understanding your air conditioner’s automatic protection
Anti-freezing protection - When the ambient temperature is very low under Cooling mode, the compressor and motor
will stop working if the coil temperature is below -2° C (28.4° F). When the coil temperature increases to above 8° C (46.4° F),
the protection turns off and the previous mode resumes. When anti-freezing protection is active, E4 appears on the
display.
Water-full protection - When the water level in the bottom water pan exceeds the warning level, the unit will alert
automatically, “FL” and “Water Full” will flash on the display. Turn off your air conditioner and drain the water as described
in “Emptying the water collection tank” on page 22. After you have drained the water, restart your air conditioner.
Compressor delay protection - Except for the first power-on, the compressor can start instantly. In other cases, the
compressor will start after three minutes delay protection.
