WARNING: ELECTRICAL HAZARD
For all electrical work, follow all local and national wiring
standards, regulations, and the Installation Manual.
The power supply to the outdoor unit requires a service
disconnect at the unit. Only use a dedicated circuit. Never
share a power source connected to this system. 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.
If the power supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly qualified
persons such as a licensed electrician in order to avoid a
hazard.
The product must be properly grounded at the time of
installation, or electrical shock may occur.
CAUTION: BURN HAZARD
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.
NOTICE: PROPERTY DAMAGE
Install condensate drainage piping according to the
instructions in this manual. Improper condensate drainage
may cause water damage to your home and property.
CAUTION: CONTAINS REFRIGERANT
This air-conditioning unit contains fluorinated gases. For
specific information on the type of gas and the amount,
please refer to the relevant label on the outdoor unit itself.
Installation, service, maintenance and repair of this unit
must be performed by a certified technician.
Product removal and recycling must be performed by a
certified technician.
If the system has a leak-detection system installed, it must
be checked for leaks at least every 12 months.
When the unit is checked for leaks, proper record-keeping of
all checks is strongly recommended.
