z

During the operation, the entire capacity of the cooperating indoor unit should be not larger than that of outdoor unit. Otherwise, it will cause the shortage of cooling (heating) capacity.

z

A Breaker (or fuse) needs to be installed in every indoor unit, and the capacity should in according with indoor unit’s electrical parameter; all the indoor units are required to be centralized controlled by a total Switch, this Switch can cut off the electric power supply in case of emergency.

The breaker (or fuse) on each indoor units has the function of short circuit prevention and avoiding abnormal overload, and it should be connected in normal situation. The main switch should be capable of controlling the power supply of all the indoor units. Before clearing and maintenance job being carried out to the indoor units, it is very important to turn off the total power supply switch.

z

In order to turn on the units successfully, the main power switch should be opened 8 hours before the operation.

z

After receiving the turn off signal, every indoor unit will continue to work for 20-70sec to make use of the rest cool air or the rest heat air in the heat exchanger, while preparing for the next operation. And this is normal.

z

When the selected operating mode of the indoor unit are clash with the operating mode of the outdoor unit, the malfunction light will blink after 5s on the indoor unit or remote controller showing that the operation clash, then the indoor unit will stop. At this time, change the operation mode of the indoor unit to the one that would not clash with the outdoor operating mode to make the operation normal. The cooling mode is not clash with the dry mode, while the fan mode is not clash with any mode.

z

The appliance shall not be installed in the laundry

SAFETY INFORMATION

Please read this manual carefully before use this unit, and operate it correctly according to the guide in this manual. Also, please take specially notices to the meaning of these two symbols:

Warning!This mark means that it may cause casualty or badly hurt if the operation is incorrect.

Note!This mark means that it may cause casualty or property loss if the operation is incorrect.

Warning

z For the usage safety of the air conditioner, the units should be earthed reliably, and the earth wire should be connected to the special earth equipment in building. If there is no this kind of equipment, have the units installed by specialized personnel. Do not connect the earth line with the gas pipe, water pipe, drainage pipe or other places that specialized personnel considers unsafe. z Air conditioner must use special power supply circuit and switches for creepage protect and air with enough capacity should be installed in the circuit. z Ensure that the connecting of power cord is normal, otherwise, electric shock or fire may happen. z Do not cut off the power supply to turn off the unit when it is running, otherwise the useful life of units may shortened. z Do not mangle wire or adopts wires that are not recommend to use, otherwise, electric shock or fire may happen. z Please don’t operate the unit by wet hand, or electric shock may happen. z Don’t insert finger or stick like things into outlet vent, otherwise, damage may happen. z Cut down the main power switch immediately if malfunction (such as smell the burning odor etc.) happen, and then contact the special engaged maintenance center. If the abnormal state is maintained, the unit may be damaged or electric shock or fire may happen. z Do not refit the conditioner. Please contact the agency or professional personnel to repair or move the conditioner. z Do not adopt fuse with unsuitable capacity or adopt iron thread instead of fuse, otherwise malfunction or fire may happen. z Do cut off the main power supply of air conditioner if it would not be used for a long time. z Please turn off the main power of the unit before cleaning the conditioner, otherwise electric shock or harm may happen. z Don’t blow the heater otherwise carbon monoxide may be produced for uncompleted burning. z Chemical sprayer should be placed 1m or more away from the unit, otherwise fire or explode may be caused. z No blockage is permitted in the inlet or outlet vent of the air conditioner, as this would cause low efficacy or unit stop.
