WARNING
NOTICE
ELECTRICAL WARNINGS
1. The product must be properly grounded during installation or electrical shock could occur.
2. For all electrical work,follow all local and national wiring standards, regulations, and the installation
manual. Connect cables tightly and clamp them securely to prevent external forces from damaging the
terminal. Improper electrical connections could overheat, causing re and/or electrical shock.
3. All electrical connections must be made according to the Electrical Connection Diagram located on the
panels of the indoor and outdoor units.
4. If connecting power to xed wiring, an all-pole disconnection device must be incorporated in the xed
wiring in accordance with the wiring rules and must meet the following requirements: at least 3 mm of
clearances in all poles, a leakage current that may exceed 10 mA, and a residual current device (RCD)
having a rated residual operating current not exceeding 30 mA.
5. All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not properly closed, it can lead to corrosion and cause the connection points on the
terminal to heat up, catch re, or cause electrical shock.
WARNING
1. Turn o the device and disconnect the power before performing any installation, cleaning, or repairs.
Failure to do this could result in electrical shock.
2. This appliance is not intended for use by persons (including children) with reduced physical, sensory,
or mental capabilities, or lack of experience or knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
