Indoor Unit 

Installation

 BEFORE PERFORMING ANY 
 ELECTRICAL WORK, READ THESE 
 REGULATIONS 

1. All wiring must comply with local and national 

    electrical codes, regulations and must be 

    installed by a licensed electrician.

2. All electrical connections must be made 

    according to the Electrical Connection Diagram

    located on the panels of the indoor and outdoor 

    units. 

3. If there is a serious safety issue with the power 

    supply, stop work immediately. Explain your

    reasoning to the client, and refuse to install the 

    unit until the safety issue is properly resolved.

4. Power voltage should be within 90-110% of 

    rated voltage. Insufficient power supply can

    cause malfunction, electrical shock, or fire. 

5. If connecting power to fixed wiring, install a 

   surge protector and main power switch with 

   a capacity of 1.5 times the maximum current 

   of the unit.  

6. If connecting power to fixed wiring, a switch 

    or circuit breaker that disconnects all poles and 

    has a contact separation of at least 1/8in (3mm) 

    must be incorporated in the fixed wiring. The 

    qualified technician must use an approved 

    circuit breaker or switch.    

7. Only connect the unit to an individual branch 
    circuit outlet. Do not connect another 
    appliance to that outlet.   
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose 
    wiring can cause the terminal to overheat, 
    resulting in product malfunction and possible fire.
    Do not let wires touch or rest against refrigerant 
    tubing, the compressor, or any moving parts 
    within the unit.  
    If the unit has an auxiliary electric heater, it must
    be installed at least 1 meter (40in) away from 
    any combustible materials. 
    To avoid getting an electric shock, never touch 
    the electrical components soon after the power 
    supply has been turned off. After turning off 
    the power, always wait 10 minutes or more 
    before you touch the electrical components.  

 WARNING

BEFORE PERFORMING ANY ELECTRICAL 
OR WIRING WORK, TURN OFF THE 
MAIN POWER TO THE SYSTEM. 

Step 6: Connect signal cable

The signal cable enables communication between 

the indoor and outdoor units. You must first 

choose the right cable size before preparing it for 

connection.

CHOOSE THE RIGHT CABLE SIZE

The size of the power supply cable, signal 

cable, fuse, and switch needed is determined 

by the maximum current of the unit. The 

maximum current is indicated on the nameplate 

located on the side panel of the unit. Refer to 

this nameplate to choose the right cable, fuse, 

or switch.
