USER NOTICES
• The total capacity of the indoor units running at the same time cannot exceed 150% of the outdoor
unit capacity. Otherwise, the cooling or heating effect of each indoor unit will be poor.
• To ensure a successful startup, switch the main power on 8 hours before powering on the unit.
• After receiving the “Off” signal, each indoor unit will continue to operate for 20 to 70 seconds to use the
remaining cool or warm air in the air exchanger while preparing for the next operation. This is normal.
• When the operating mode of the indoor unit is in conflict with that of the outside unit, a malfunction
light will blink for 5 seconds on the indoor unit display or on the controller to warn the user. Then the
indoor unit will stop. Change the operating mode of the indoor unit to match that of the outdoor unit
or with a compatible mode. COOL mode is compatible with DRY mode and FAN mode is compatible
with all operating modes.
• If the supply power fails when the unit is running, the indoor unit will send the “start” signal to the
outdoor unit three minutes after power recovery.
• This appliance is not intended for use by people (including children) with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they are under the supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
