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.
4. Ensure the air conditioner is grounded well.
5. According to the attached Electrical Connection Diagram located on the panel of the outdoor unit
to connect the wire.
6. All wiring must comply with local and national electrical codes and be installed by qualified and
skilled electricians.
7.
An all-pole disconnection device which has at least 3mm separation distance in all pole and a residual
current device(RCD) with the rating of not exceeding 30mA shall be incorporated in the fixed wiring
according to the national rule.
8. An individual branch circuit and single receptacle used only for this air conditioner must be
available. See the following table for suggested wire sizes and fuse specifications:

Connect the cable to the indoor unit
NOTE:
Before performing any electrical work, turn off the main power to the system.
1. For model A, first remove the front cover on chassis by loosening the screw, then remove the front
cover of frame as shown below. For model B, just open the panel up, then remove the electrical control
box cover by loosening the screw.
3. The indoor power cord type is H05VV-F or H05V2V2-F, the outdoor power cord and interconnected
cord type is H07RN-F. 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.
NOTE: If used as MONO unit, for the standby control needs, the cross section area of cable connected
to L(1), 1, 2(N) must be sufficient for the maximum system current. The maximum system current is
equal to the sum of indoor unit and outdoor unit rated current. If used as MULTI unit, L(1) on the terminal
block does not need to be connected.
