Precautions for safety
Installing, starting up, and servicing air--conditioning equipment
can be hazardous due to system pressures, electrical
components, and equipment location
(roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should
install, start--up, and service this equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning heat exchanger.
All other operations should be performed by trained service
personnel.
Before working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
Follow all safety codes. Wear safety glasses and work gloves.
Keep quenching cloth and fire extinguisher nearby during brazing.
Use care in handling, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or
cautions included in literature and attached to the unit.
Consult local building codes and National Electrical Code (NEC)
for special requirements. Recognize safety information.
This is the safety--alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury. Understand
these signal words: DANGER, WARNING, and CAUTION.
These words are used with the safety--alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.

The manufacturer shall not assume any liability for the damage
caused by not observing the description of this manual.
WARNING
Only a qualifi fied installer or service person is allowed to do
installation work.
Inappropriate installation may result in water leakage, electric
shock or fire.
Do not use any refrigerant different from the one specified
for complement or replacement.
Otherwise, abnormally high pressure may be generated
in the refrigeration cycle, which may result in a failure or
explosion of the product or an injury to your body.
Connect earth wire. (grounding work)
Incomplete grounding may cause an electric shock.
Do not connect grounding wires to gas pipes, water pipes,
lightning rods or grounding wires for telephone wires.
Turn off all the circuit breaker before attempting any
electrical work.
Failure to do so may cause electric shock.
Install the refrigerant pipe securely during the installation
work before operating the air conditioner.
If the air conditioner is operated with the valve open and
without the refrigerant pipe, the compressor sucks air and the
refrigeration cycle is overpressurized, which may cause a burst
or injury.
When moving the air conditioner for the installation into
another place, do not enter any gaseous matter other than
the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas
pressure in the refrigeration cycle becomes abnormally high and
it resultingly causes pipe burst and injuries on persons.
