Introduction
Precautions
Read these Safety Notes carefully before installing this unit.
1
These Safety Notes contain very important safety information. Always be sure to observe these
cautions.
After installation is complete, trial the operation of the unit to make sure that it is operating
normally. Instruct the customer about how to operate the unit, and about necessary
maintenance.
The dealer or a special contractor must install this unit.
Attempts to install this unit by a customer could result in leaks, electric shock, or fire.
Improper installation could result in leaks, electric shock, or fire.
If this unit is installed in a small room, measures must be taken to ensure that, even
in the event of a refrigerant leak, the maximum safe limit for refrigerant
concentration levels in the air is not exceeded.
Consult the dealer for details on what measures can be taken to keep from exceeding the
maximum safe limit. If a refrigerant leak does cause refrigerant concentration levels in the air
to exceed the maximum safe limit, asphyxiation could result.
Select a location for installation that will be able to safely bear the weight of the unit.
If the installation location is not strong enough to support the unit and the unit falls, injury
could result.
Install the unit in the prescribed manner to withstand strong (hurricane-level) winds
and earthquakes.
Insufficiently secure installation could allow the unit to tip over, fall, or otherwise cause an
accident.
Ventilate the area if any refrigerant leaks during installation.
If the refrigerant comes into contact with an open flame, it will produce a toxic gas.
After completing installation, make sure that no refrigerant is leaking.
If the refrigerant leaks indoors and comes into contact with an open flame in a water heater,
stove, oven, or other such appliance, it will produce a toxic gas.
Electrical work must be performed by a qualified electrician as described in the
Installation Manual.
The unit must be connected to its own independent circuit. Inadequate circuit capacity or
improper installation could result in electric shock or fire.
Wiring must be performed securely, using the prescribed cables.
The cables must be secured in a manner that prevents any force that pulls on the cables from
being relayed to the terminal connectors. If the cables are not connected or secured properly,
fire or other accidents could result.
The unit must be grounded.
Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or telephone
ground wire. When wiring the system to the main power source, follow the standards
established by the local power company. Inadequate grounding can result in electric shock.
Do not install the unit in a location where combustible gases could conceivably leak.
Leaking gases that accumulate in the vicinity of the unit could be ignited by the unit.
