User Notice
◆The total capacity of the indoor units which runs at the same time can not exceed 150% of
that of the outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be poor.
◆Switch the main power on 8 hours before start the unit, helpful for a successful startup.
◆It is a normal phenomenon that the indoor unit fan will still run for 20~70 seconds after the
indoor unit receives the “stop” signal so as to make full use of after-heat for the next operation.
◆ When the running modes of the indoor and outdoor units conict, it will be indicated on the
display of the wired controller in ve seconds and then the indoor unit will stop. In this case, they
can back to the normal condition by harmonizing their running modes: The HEAT mode conicts
with each of the COOL mode, DRY mode and FAN mode, while the COOL mode, DRY mode and
FAN mode are compatible between each other. If the supply power fails when the unit is running,
then the indoor unit will send the “start” signal to the outdoor unit three minutes later after power
recovery.
◆During installation, the communication cable and the power cord must not be twisted
together but instead separated with an interval of at least 3/4”(2cm), otherwise the unit is likely to
run abnormally.
◆This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
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.
