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 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 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, 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 for this purpose 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 should not be used by children (under the age of 8 years old) or persons with
reduced physical, sensory or mental capabilities, or lack of experience and knowledge unless they
have supervision or are given instruction concerning use of the appliance. They should be made to
understand the hazards involved with the appliance. Children should not play with the appliance or
perform cleaning and/or user maintenance.
Turn off the air conditioner and disconnect the power source before cleaning, 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 can 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.
Always 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.
