EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Excessive torque can break the flare nut depending on installation conditions.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this warning could result in personal injury or death.
Before beginning any modification or installation of this kit, ensure the main electrical
disconnect is in the OFF position. Ensure power is disconnected to the fan coil unit. On
some systems both the fan coil and the outdoor unit may be on the same disconnect. Tag
the disconnect switch with a suitable warning label. There may be more than one to
disconnect.
CAUTION
!
INSTALLATION
Entrust the distributor or authorized professionals to install the unit. Installation by
unskilled persons may lead to improper installation, electric shock, or fire.
Re−installation must be performed by authorized professionals.
Non−compliance may lead to electric shock or fire.
CAUTION

NOTE: Save this manual for future reference.
SThis manual provides a detailed description of the precautions that the user should be
mindful of during operation.
STo ensure correct service of the wired controller, read this manual carefully before
using the unit.
SKeep this manual, after reading it, for future reference.
NOTE:
1. Do not install the unit in a location vulnerable to flammable gas leaks. Once flammable gases
are leaked and left around the wire controller, a fire may occur.
2. Do not operate with wet hands or allow water to enter the wire controller, otherwise an electric
shock may occur.
3. The wiring should be a compatible connection cable for the current wired controller.
Otherwise, electric leakage or heating may occur and result in a fire.
4. The specified cables shall be applied in the wiring. No external force may be applied to the
connection wire terminal. Otherwise a wire cut and heating may occur and result in a fire.

WIRED CONTROLLER INSTALLATION PRECAUTION
1. This manual provides the wired controller installation method. Refer to the wiring diagram in
this installation manual to wire the wired controller with the indoor unit.
2. The wired controller works in a low voltage loop circuit. Do not connect directly to 208/230V
and 460V. Do not wire this kind of wire into a loop. Wiring clearance between the configured
tubes should range 11.81−19.69 inches (30−50 cm) or above.
3. The shielded wire of the wired controller must be properly grounded.
NOTE: Upon completion of the wired controller connection, do not use a tramegger to test the
insulation.
