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 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.

◆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.

This product must not be disposed together with the domestic waste. This product

has to be disposed at an authorized place for recycling of electrical and electronic

appliances.

Thank you for purchasing Sinclair air conditioners. Before use, please read this manual

carefully and keep it properly for further reference.
