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 starting 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 conflict, it will be

indicated on the display of the wired controller in five seconds and then the indoor

unit will stop. In this case, they can back to the normal condition by harmonizing

their running modes: the cooling mode is compatible with the dehumidifying mode

and the fan mode can go with any other mode. 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.

Do not frequently power on/off the unit, otherwise it would cause the compressor,

fan, mainboard, electrostatic expansion valve, or other important component

damaged, and then make the unit fail.

During installation, the communication cable and the power cord must not be

twisted together but instead separated with an interval of at least 2cm, otherwise

the unit is likely to run abnormally.

Cautions for the Debugging and Maintenance Personnel.

During debugging and maintenance, prior to the startup of the compressor make

sure the heating belt of the compressor has been energized for at least eight

hours! Once the compressor is started, it must be guaranteed that it works

continuously for at least 30 minutes, otherwise it would be damaged!

This appliance can be used by children aged from 8 years and above and persons

with reduced physical, sensory or mental capabilities or lack of experience and

knowledge if they have been given supervision or instruction concerning use of

the appliance in a safe way and understand the hazards involved. Children shall

not play with the appliance. Cleaning and user maintenance shall not be made by

children without supervision.

The appliance shall be installed in accordance with national wiring regulations.
