20.5 APPLICATION DATA

• Please read these "Safety Precautios" first then accurately execute the installation work.
• Though the precautionary points indicated herein are divided under two headings,
points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in
the WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in
the CAUTION section as well.
In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.
• After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's manual.
Moreover, ask the customer to keep this sheet together with the owner's manual.
• This system should be applied to places of office, restautant, residence and the like. Application to
inferior environment such as engineering shop could cause equipment malfunction.
• Please entrust installation to either the company which sold you the equipment or to a professional
contractor. Defects from improper installations can be the cause of water leakage, electric shocks
and fires.
• Execute the installation accurately, based on following the installation manual. Again, improper instal-
lations can result in water leakage, electric shocks and fires.
• When a large air-conditioning system is installed to a small room, it is necessary to have a prior
planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of thresh-
old concentration.
In regards to preparing this countermeasure, consult with the company from which you purchased the
equipment, and make the installation accordingly. In the rare event that a refrigetant leakage and
exceeding of threshold concentration does occur, there is the danger of a resullant oxygen deficiency
accident.
• For installation, confirm that the installation site can sufficiently support heavy weight. When strength
is insufficient, injury can result from a falling of the unit.
• Execute the prescribed installation construction to prepare for earthquakes and the strong winds of
typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling
over of the unit.
• For electrical work, please see that a licensed electrician executes the work while followig the safety
standards related to electrical equipment, and local requlations as well as the installation instructions,
and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of
electric shocks and fires.
• Accurately connect wiring using the proper cable, and insure that the external force of the cable is not
conducted to the terminal connection part, through properly securing it. Improper connection or se-
curing can result in heat generation or fire.
• Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper
installation can also result in heat generation or fire.
• When setting up or moving the location of the air-conditioner, do not mix air etc. or anything other
than the designated refrigerant within the refrigeration cycle.
• Always use accessory parts and authorized parts for installation construction. Using parts not author-
ized by this company can result in water leakage, electric shock, fire and refrigerant leakage.
• Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or
a telephone ground wire. Improper placement of ground wires can result in electric shock.
• The installation of an earth leakage breaker is necessary depending on the established location of the
unit. Not installing an earth leakage breaker may reslut in electric shock.
• Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
• For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally
insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water dam-
age to interior items.
