For all electrical work, follow all local and national wiring standards, regulations, and the
Installation Manual. You must use an independent circuit and single outlet to supply power. Do
not connect other appliances to the same outlet. Insufficient electrical capacity or defects in
electrical work can cause electrical shock or fire.
For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to
prevent external forces from damaging the terminal. Improper electrical connections can overheat
and cause fire, and may also cause 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 heat up, catch fire, or cause electrical shock.
In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended.
CAUTION
For units that have an auxiliary electric heater, do not install the unit within 1 meter (3 feet) of
any combustible materials.
Do not install the unit in a location that may be exposed to combustible gas leaks. If
combustible gas accumulates around the unit, it may cause fire.
Do not operate your air conditioner in a wet room such as a bathroom or laundry room. Too
much exposure to water can cause electrical components to short circuit.
1. The product must be properly grounded at the time of installation, or electrical shock may occur.
2. Install drainage piping according to the instructions in this manual. Improper drainage may cause
water damage to your home and property.
