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 and/or fire.
Connect electrical cables tightly and securely to the terminal board to prevent external forces from
damaging the terminal.
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 hazard.
This appliance can be used by children (aged 8 years and above) and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge only 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 the
power source, otherwise electric shock could occur.
If installed in a compact space, ensure that there is adequate ventilation in case of leakage. A
concentration 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, and work gloves during installation. Also, have a fire
extinguisher available in case of an emergency.
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 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 every 12
months.
Keep a record of all leak checks for the lifetime of the unit.
