16. OPERATION RANGE
Please observe the following points in order to use the air conditioner in a safe and comfortable manner.
Make sure to request your dealer for installation, and do not attempt to do by yourself.
Is the system installed in a well-ventilated place?
Are there any obstacles? If so, it leads to the decrease of the efficiency and the increase of operation noise.
Avoid the place where cool/warm air and operation noise cause problems to your neighbors.
INSTALLATION LOCATION
Normally the efficiency of the air conditioning system will become lower after a while, because dirt accumulates inside the system. This occurs gradually in around
3 years of use, depending on the condition of use and surrounding environment. It is thus necessary to conduct inspection maintenance in addition to regular
maintenance. We recommend you to consult the dealer from whom you purchased the system and make a contract for periodical inspection. (charged).
Warning :
Make sure to consult a dealer or specialist if it is required to relocate and
reinstall the air conditioning system.
If the air conditioning system is installed incorrectly, water leakage, electric shock and/or fire may
occur. Note that an installation fee will be charged for relocation and installation.
Caution :
Make sure to perform grounding work
Do not connect the ground wire to any gas pipe, water pipe, or wires of lightning conductors and
telephones. If the ground work is not good, it may lead to electric shock
.
Caution :
A leakage breaker is necessary depending on the installation environment.
If it is not mounted there, it may lead to electric shock.
Only qualified specialists of electrical and grounding work can do these works according to “electric equipment technical standards”.
Is the wiring designated for the air conditioner?
Is the remote control mounted correctly?
•
In the case of exposed wiring, is the wiring fixed with the attached screw?
•
Is the attached remote control clamps used for fixing the remote control cord?
•
Is the remote control mounted at a height where children cannot reach?

This air conditioner complies with DRED standards as per AS/NZS4755.3.1. It supports demand response modes 1, 2 and 3
(DRM1, 2, and 3).
The outdoor unit of this air conditioner is equipped with a DRED-speci
fi
c terminal block.
It also supports ELV(Extra-Low Voltage) as per AS/NZS60335.1.
Because the air conditioner is programmed to limit electrical power consumption when receiving the DRED input signal, cooling or
heating capacity may be reduced.
In DRED-enabled mode, a small “D” is displayed on the remote controller, as shown on the pictures below. When the defrost cycle
becomes active during DRED operation, touch screen controller continue to display the DRED active “D” symbol.
However, the normal controller does not ; only “DEFROST” is displayed even though DRED mode remains active.
