DUAL, TRIPLE, POKER DC Inverter : 4. Installation
Multi Liberty
DC Inverter
WARNING
This system should be applied to places as households, residences and the like. Application to other 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 Installer.
Defects from improper installations can be the cause of water leakage, electric shocks and fires.
Execute the installation accurately, based on following the Installation instructions. Again, improper installations
can result in water leakage, electric shocks and fires.
If an air-conditioning system of high capacity is installed in a small room, it is needed to take the necessary
countermeasures to face up to the rare event that in case of
R410A
refrigerant leakages, the gas concentration
exceeds the threshold value
(0.3kg/m
3
)
. In this rare possibility, there is a risk of lack of oxygen. In order to
prepare the suitable countermeasures, please call the Distributor who sold you the air conditioner.
If during the Indoor Unit’s installation work the refrigerant gas leaks, it is necessary to immediately ventilate
the room, as if the gas gets in contact with a heating source or fire, it becomes toxic.
Confirm after the installation work that refrigerant does not leak. If coming in contact with fire or heating sources
(a fan heater, a stove or movable cooking stove, etc.), refrigerant leaking in the room could generate toxic gas.
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is
insufficient, injury can result from a falling of the Units.
For electrical work, please check that a licensed Electrician executes the work while following the safety
standards related to electrical equipment, and local regulations as well as the installation instructions, and
that only exclusive use circuits are used. Insufficient power source circuit capacity and defective instalment
execution can be the cause of electric shocks and fires.
Accurately connect wiring by using the proper cable, and ensure that the external force of the cable is not
conducted to the terminal connection part, through properly securing it; improper connection or securing can
result in heat generation or fire.
Take care to insert the electrical cables into the electric box by the bottom side (so as to avoid water that may
reach the cable to enter the electric box), and accurately install the special service cover on the Unit’s panel.
Improper installation can result in heat generation or fire.
When setting up or moving the location of the air conditioner, do not mix air or anything other than the designated
refrigerant
R410A
within the refrigerating cycle. If air enters the refrigerating circuit, compressor may break
down or it may occur malfunctions and/or abnornal high pressure.
For the installation, always use accessories and components authorized by the Manufacturer. If using
unauthorized parts, this may result in water leaks, electric shocks, fire and/or refrigerant leaks.
