10• When installing a Wi-Fi kit with 10 m (32.8 feet) or more wire, the communication wire and power wire of a Wi-Fi kitshould be installed separately. (The Wi-Fi kit will malfunction because of electrical fault. )• When installing a Wi-Fi kit on the wall, select proper thickness of wires in the consideration of the hole size for wireon the wall.• Wire for Wi-Fi kit PCB connection- When installing a Wi-Fi kit in a buried way, install the kit in accordance with U-terminal wiring Specification.- When installing a Wi-Fi kit with 4 core PVC cable, peel off 30 cm (0.98 feet) of the sheath before installing.(Recommendation: AWG22)• Specification of compressed U-terminal for connecting Wi-Fi kit PCBWire range forconnectionRatedsizeStudsize Basic size(mm)AWG mm2 mm2 mm t ΦD G E F W L22~16 0.25~1.65 1.5 3 0.7 3.8 10.0 4.5 6.5 6.0 21.2The maximum wiring length for communication and power : 50 m (164 feet)• Tighten the fixing screws to the PCB terminal with less than 6N·cm torque. When the screws are tightened withmore than 6N·cm torque, the screw thread will be damaged.6. Run the Wi-Fi kit.f When the Wi-Fi kit is turned on, all the lamps are turned on until system operates.f After the system operates, tracking is performed automatically.7. Perform the tracking.❋ Tracking : You can search the devices connected to the Wi-Fi kit with the tracking function. The devices connected to Wi-Fikit recognize that they are connected to the Wi-Fi kit. To monitor or control the system air conditioner with Wi-Fikit, tracking should be performed.f When the Wi-Fi kit is turned on, the tracking is performed automatically. During the tracking, the lamp ofthe Wi-Fi kit ( ) ( ) blinks.f If the tracking is completed but the lamp ( ) blinks, it means the Wi-Fi kit does not find connected indoor units. In thiscase, check whether the connection of communication cable between indoor unit and outdoor unit is correct or isaffected by noise.f If the configuration of indoor unit or outdoor unit is changed, tracking should be performed again manually by pressingthe button (SW3) inside the Wi-Fi kit. ( - )• If you want to control the indoor unit with the Wi-Fi kit, indoor unit’s centralized control usage option must be set to“Enable”.• If you want to control the indoor unit with the Wi-Fi kit, tracking must be done properly and connect the Wi-Fi kit toa wired/wireless router.• When the tracking is completed correctly, the lamp ( ) is turned on until the process which connects the wired/wireless router to Wi-Fi kit is completed.CAUTIONCAUTIONNOTEHow to install Wi-Fi kit
