Local codes often require a disconnect switch located near
the unit; do not install the switch on the unit.
Overcurrent Protection
The inverter control system software provides sufficient
time delay to protect from overcurrent conditions and
permit the compressor and fan motors to adjust their
rotational speed.
High Voltage Connections
Route power supply and ground wires through the high
voltage port and terminate in accordance with the wiring
diagram provided inside the control panel cover.
• Make sure to apply the rated voltage of 208/230V for
the unit.
• Use conduit for power supply cables.
• A power circuit (see the production specification
sheet or the unit serial plate) must be provided for
connection of the unit. This circuit must be protected
with the required safety devices.
• When using residual current operated circuit breakers,
be sure to use a high-speed type (0.1 seconds or
less) 200 mA rated residual operating current.
• Use copper conductors only.
• Use insulated wire for the power cord.
• Select the power supply cable type and size
in accordance with relevant local and national
regulations.
• Outside the unit, make sure to keep the wirings 5 inch
away. Otherwise, the outdoor unit may be affected by
electrical noise (external noise), and malfunction or
fail.
• Make sure the wirings will not be pinched by the front
panel, and close the panel firmly.
• Route the conduit along the unit and so on to prevent
wirings from being stepped on.
Low Voltage Connections
The unit is designed to work as part of a fully
communicating HVAC system, utilizing either:
• ComfortBridge compatible indoor unit with any 24V
single stage thermostat.
• CTK04AE or newer thermostat (If paired with
ComfortNet compatible indoor unit.)
Route control wires through the low voltage port and
terminate in accordance with the wiring diagram provided
inside the control panel cover.

Thermostat Wiring
ComfortBridge
™
control system low voltage wiring consists
of two wires between the indoor unit and outdoor unit. The
required wires are data lines 1 and 2.
The thermostat needs 4 wires between the indoor unit and
thermostat or 5 wires if the thermostat requires a Common
wire.
NOTE: For regions with high humidity, it is
strongly recommended to use a thermostat with
humidity sensor and dehumidification terminal.
Without this type of thermostat, dehumidification
operation does not work.
Regarding the wiring of the indoor unit to the thermostat,
also refer to ComfortBridge compatible indoor unit’s Install
manual (in case of communicating inverter system.).
If installing with a CTK04 thermostat, please see the
addendum for further instructions.
