Step 6: Make electrical connections
• Open the front panel.
• Remove the electrical box cover.
• Route the power connection cord from the back of the indoor unit and pull it toward the front through
the wiring hole upward.
• Put the 4-core cable through the hole of the chassis and the bottom of the appliance upward, and then
connect the power line and the communication line from the outdoor unit to the corresponding ter-
minals N(1), 2, 3 , and grounding terminal of the indoor unit. Wiring shall be done properly as per the
wiring diagram. (Note: Be sure the wiring terminals A/B/C/D and piping joints A/B/C/D of the indoor
unit match with that of the outdoor unit respectively).
• Reinstall the electrical box cover.
• Reinstall the front panel.
NOTES:
• All wires of indoor and outdoor unit should be connected by a qualified person.
• If the length of power connection wire is insufficient, please contact your dealer for a new one. Do not
extend the wire by yourself.
• A circuit break must be installed in the line. The air switch should be all-pole parting and the contact
parting distance should be more than 3 mm.
• Do not use copper tube at the interconnection part as the temperature of refrigerant circuit is high.
Step 7: Bind up pipes
• Bind up the connection pipe, power cord and drain hose with the band.

• Reserve a certain length of drain hose and power cord for installation when binding them.
When binding to a certain degree, separate the indoor power and then separate the drain hose.
• Bind them evenly.
• The liquid pipe and gas pipe should be bound separately at the end.
NOTES:
• The power cord and control wire cannot be crossed or winded.
• The drain hose should be bound at the bottom.
