4. Installation
I nstruction To prevent abnormal heat generation and the possibility of fire, do not place obstacles, enclosures and grilles in front of or surrounding the air conditioner in a way that may clock air flow. And, more than 1 meter away from any antenna or power lines or connecting wires used for TV, radio, telephone, security system, or intercom.

The outdoor fan’s speeds except the single speed motor can be changed according to outdoor ambient temperatures. When operating at a fixed frequency, the outdoor fan is forced to operate at the high speed. 3-6-2 Indoor fan operation (1)When the indoor fan keep in running condition, this operation state could be controlled by the remote control with High, Median, Low and Automatic setting.

3-7-2 Indoor fan motor operation Anti-cold air system: When the appliance run in Heat mode condition, the indoor fan motor operation is shown as following to prevent the cooling air come out during the appliance operation. When the appliance turn in the anti-cold air system in the Extra-LOW (Tapped motor set in LOW, sic passim) during the compressor operation, the louver swang to the Cool air protection position, the louver recovers to the original position after the air volume change to LOW.

During the louver run in normal operation, the current position will be stored. When the appliance turn off and louver swing automatically to the default position, it will position at the default position plus 5º. 4-3-8-4 Outdoor fan The outdoor fan speeds except single speed motor can be changed according to outdoor ambient temperatures.

Current protection: 1.Protection against over-current Conditions for over-current protection: if the current is equal to or greater than “current value for starting the refrigeration current protection (E2 value)” for six seconds, over-current protection starts. Protection actions against over-current: indoor display screen and outdoor indicator give indications, the compressor and outdoor fan stop, but indoor fan runs normally.
compressor maintains at the current level, which may decrease as the case requires while cannot rise. The indoor and outdoor fans run. Condition for ending anti-overload prohibition of frequency of outdoor coiled pipe: if the temperature of outdoor coiled pipe drops below “temperature to release the anti-overload state of outdoor coiled pipe”, anti-overload prohibition of frequency of outdoor coiled pipe will be released.
