• Do not install unit in an area where flammable materials
are present due to risk of explosion resulting in serious
injury or death.
• Do not ground units to telephone wires or lightning rods
because lightning strikes could cause a severe shock
hazard resulting in severe injury or death, and to gas
pipes because a gas leak could result in an explosion
which could lead to severe injury or death.
WARNING
• Installation shall be left to the authorized dealer or another
trained professional.
Improper installation may cause water leakage, electrical
shock, fire, or equipment damage.
• Install the air conditioner according to the instructions
given in this manual.
Incomplete installation may cause water leakage,
electrical shock, fire or equipment damage.
• Be sure to use the supplied or exact specified installation
parts.
Use of other parts may cause the unit to come to fall,
water leakage, electrical shock, fire or equipment damage.
• Install the air conditioner on a solid base that is level and
can support the weight of the unit.
An inadequate base or incomplete installation may cause
injury or equipment damage in the event the unit falls off
the base or comes loose.
• Electrical work shall be carried out in accordance with
the installation manual and the national, state and local
electrical wiring codes.
Insufficient capacity or incomplete electrical work may
cause electrical shock, fire or equipment damage.
• Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance.
Follow all appropriate electrical codes.
• For wiring, use a wire or cable long enough to cover the
entire distance with no splices if possible.
Do not use an extension cord. Do not put other loads on
the power supply.
Use only a separate dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock,
fire or equipment damage.)
• Use the specified types of wires for electrical connections
between the indoor and outdoor units.
Follow all state and local electrical codes.
Firmly clamp the inter-unit wire so their terminals receive
no external stresses.
Incomplete connections or clamping may cause terminal
overheating, fire or equipment damage.
• After connecting all wires be sure to shape the cables so
that they do not put undue stress on the electrical covers,
panels or terminals.
Install covers over the wires. Incomplete cover installation
may cause terminal overheating, electrical shock, fire or
equipment damage.
• When installing or relocating the system, be sure to keep
the refrigerant circuit free from all substances other than
the specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the
refrigerant circuit causes an abnormal pressure rise which
may result in rupture, resulting in injury.)
• During pump down, stop the compressor before removing
the refrigerant piping.
If the compressor is still running and the stop valve is
open during pump down, air will be sucked in when the
refrigerant piping is removed, causing abnormally high
pressure which could lead to equipment damage or and
personal injury.
• During installation, attach the refrigerant piping securely
before running the compressor.
If the refrigerant pipes are not attached and the stop valve
is open during installation, air will be sucked in when the
compressor is run, causing abnormally high pressure
which could lead to equipment damage and personal
injury.
• Be sure to install a ground fault circuit interrupter.
Failure to install a ground fault circuit interrupter may
result in electrically shocks, or fire personal injury.
CAUTION
• Do not install the air conditioner where gas leakage would
be exposed to open flames.
If the gas leaks and builds up around the unit, it may catch
fire.
• Establish drain piping according to the instructions of this
manual.
Inadequate piping may cause water damage.
• Tighten the flare nut according to the specified torque. A
torque wrench should be used.
If the flare nut is tightened too much, the flare nut may
crack over time and cause refrigerant leakage.
• Do not touch the heat exchanger fins.
Improper handling may result in injury.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not
use any PP bands for a means of transportation. It is
dangerous.
• Electrical work must be performed in accordance with the
NEC/CEC by authorized personnel only.
