Install the unit in a firm location that can support the unit’s weight. If the installation location
cannot support the weight, or the installation is performed improperly, the unit may fall and
cause serious injury and/or damage.
For all electrical work, follow all appropriate wiring standards, regulations, and the Installation
Manual.
You must use an independent circuit to supply power. Do not connect other appliances to the
same circuit. Insufficient electrical capacity or defects in electrical work can cause electrical
shock or fire.
Connect electrical cables tightly and clamp them securely to prevent external forces from
damaging the terminal. Improper electrical connections may overheat, causing fire and/or
electrical shock.
All wiring must be properly arranged to ensure that the control board cover can close properly.
If the control board cover is not closed properly, it can lead to corrosion and cause the
connection points on the terminal to overheat , causing fire and/or electrical shock.
In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended. If the power or thermostat wires are
damaged, they must be replaced by an authorized technician in order to avoid hazard.
