WARNING:
• The electric circuit diagram given on the indoor/outdoor units must be taken as the main reference for
installation.
• The power wires and signal wires between the indoor/outdoor units must be connected one by one as
per corresponding number on the wiring terminal board.
• The connecting cables must be clipped together.
• Special cable must be used to connect indoor unit and outdoor unit. It should be ensured that the
terminals are not influenced by external force. Poor connection may cause fire.
• The electric box cover must be mounted and secured in position, otherwise fire or electrical shock may
occur because of dust or moisture.
• All models must be connected to mains power with system impedance limitations.
• While installing the unit, please see the following table for impedance information or contact the utility
company.
Installation of the drain joint (only for heat pump
type)
• Insert the outdoor double-channel drain joint in one of
the bottom holes of the right size then connect the drain
hose and joint together.
Connecting pipe joint
• Use some airproof oil to cover the joint and the expanding orifice of the connecting pipe.
• Align the centre of the joint with that of the expanding orifice and tighten the nut of the connecting pipe
with a wrench. (Adjust the torque using the same method used for connecting the pipe for the indoor
unit.)
