SECTION 3 SERVICE MANUAL

SAFETY NOTES

• Read these Safety Notes carefully before installing this unit.
• These Safety Notes contain very important safety information. Always be sure to observe these cautions.
• After installation is complete, try the operation of the unit to make sure that it is operating normally.
Be certain to instruct the customer about how to operate the unit, and about necessary maintenance.
Give this Installation Manual to the customer along with the Owner's Manual, and recommend that the
customer keeps both for future reference.
• 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.
• Follow these instructions carefully when installing this unit.
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 supply, follow the standards established by the local power
company. Inadequate grounding can result in electric shock.
• Install a ground fault interrupter.
If a ground fault interrupter is not installed, electric shock could result.
• 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.
