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 could fall and
cause serious personal injury and/or property 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 could cause
electrical shock and/or fire.
Connect electrical cables tightly and clamp them securely to prevent external forces from
damaging the terminal. Improper electrical connections could 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, which could cause fire and/or electrical shock.
In certain functional environments (such as kitchens and server rooms), 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 a hazard.
This appliance can be used by children aged 8 years and older and persons with reduced
physical, sensory, or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance and understand the hazards
involved. Children should not play with the appliance. Cleaning and user maintenance should
not be performed by children.
The air conditioner unit can only be cleaned after it has been turned off and disconnected from
its power source, otherwise electric shock could occur.
If installed in a compact space, ensure that there is adequate ventilation in case of leakage.
Concentrations of refrigerant gas could lead to an explosion and other hazards.
The fixed wires connecting to this appliance must be configured with an all-pole disconnect
under voltage class III.
Wear safety glasses, protective clothing, work gloves, and have a fire extinguisher available
during installation.
Always use a quenching cloth for brazing operations.
This air-conditioning unit contains R-410A fluorinated gases.
The refrigerant gas may not have an odor, so this should not be considered as a means of leak
detection.
Installation, service, maintenance, and repair of this unit must be performed by a certified
technician.
Product un-installation and recycling must be performed by a certified technician.
If the system has a leak-detection system installed, it should be checked for leaks at least once
every 12 months.
Keep a record of all leak checks for the lifetime of the unit.
