Figure 95: Cable / Refrigerant Piping / Drain Hose Installation Options.
Cable Installation When Piping is on the Left Side:
• Insert the communication / connection (power) cable through the
bottom of the indoor unit,
• Connect the terminals to the terminal block.
• Secure the cable onto the terminal block with the cable retainer.
• Secure the refrigerant piping, drain hose, and communication /
connection (power) cable together using cable ties and conduit, or
by the bundling method.
• Each wire must be securely attached to the terminal block.
• Ground cable must be longer than the other wires.
• Secure the cable onto the control board using a cable tie.
• Use a conduit to protect the cable / refrigerant piping from the
indoor unit to the outdoor unit.
Cable Installation When Piping is on the Right Side:
• Connect the terminals to the terminal block.
• Secure the cable onto the terminal block with the cable retainer.
• Secure the refrigerant piping, drain hose, and communication /
connection (power) cable together using cable ties and conduit, or
by the bundling method.
Position the drain hose at the bottom. Positioning the drain hose at the
top of the bundle can cause condensate to overow from the drain pan
in the inside of the indoor unit.
For more information on conduits or the bundling method, see the
Refrigerant Piping Connection section.

ble).
Indoor Unit Electrical Connections
LS090-120HEV2, LS090-120HFV3 and LS090-120HXV2 indoor units and outdoor units have similar frames; however,
LS090-120HEV2 and LS090-120HFV3 systems require 208-230V, 60Hz, 1ph power supply. LS090-120HXV2 systems require
115V, 60Hz, 1ph power supply. Verify which system is being installed. An incorrect power supply will result in electric shock,
re, physical injury, or death.
