Electric safety regulations for the initial Installation
1 If there is serious safety problem about the power supply, the technicians should refuse to install the air conditioner and explain
to the client until the problem is solved
2 Power voltage should be in the range of 90 % ~ 110 % of rated voltage
3 The surge protector and main power switch with a 1 5 times capacity of Max Current of the unit should be installed in power
circuit Ensure the air conditioner is grounded well
4 The appliance shall be installed in accordance with national wiring regulations Do not operate your air conditioner in a wet
room such as a bathroom or laundry room
5 An all-pole disconnection device which has at least 3 mm clearances in all poles, and have a leakage current that may exceed
10 mA, the residual current device (RCD) having a rated residual operating current not exceeding 30 mA, and disconnection
must be incorporated in the fixed wiring in accordance with the wiring rules
6 For the unit adopts auxiliary electric heater, keep at least 1 meter away from the nearest combustible materials
7 According to the attached Electrical Connection Diagram located on the panel of the indoor & outdoor unit to connect the wire
8 All wiring must comply with local and national electrical codes and be installed by qualified and skilled electricians

Connect the cable to the indoor unit
NOTE: Before performing any electrical work, turn off the main power to the system.
1 The inside and outside connecting cable can be connected without removing the front grille
2 The indoor power cord type is H05VV-F or H05V2V2-F, the outdoor power cord and interconnected cord type is H07RN-F
3 Lift the indoor unit panel up, remove the electrical box cover by loosening the screw
4 Ensure the colour of wires of outdoor unit and the terminal Nos are the same to the indoor s respectively
5 Wrap those cables not connected with terminals with insulation tapes, so that they will not touch any electrical components
Secure the cable onto the control board with the cord clamp

current of the fuse or switch are determined by the maximum current
indicated on the nameplate which located on the side panel of the
unit. Please refer to the nameplate before selecting the wire size, fuse
or switch.
„ „ The controller of the air conditioner designed with a fuse protec-
tion function under abnormal conditions, the specifications of the
fuse have printed on the circuit board, such as: T3.15A/250VAC,
