Precautions in terms of safety
Carry out installation work with reliability after thorough reading of this “Precautions in terms of safety”.
This mark means “Caution” or “Warning”. This mark means “Earth”.
   Warnings
The appliance must be installed by technician, who takes into 
account the requirements given by ISO5149 or eventual 
equivalent requirements.
Wiring shall be connected securely using specified cables and fix 
them securely so that external force of the cables may not transfer 
to the terminal connection section.
Imperfect connection and fixing leads to fire, etc.
As to installation, request the distributor or vendor to perform it. 
Imperfection in installation caused by that having been carried out 
by the customer himself may lead to water leakage, electric 
shock, fire, etc.
If installing inside a small room, measures should be taken to 
prevent refrigerant levels from building up to critical concentrations 
in the event of a refrigerant leak occurring. Please discuss with the 
place of purchase for advice on what measures may be necessary 
to prevent critical concentrations being exceeded. If the refrigerant 
leaks and reaches critical concentration levels, there is the danger 
that death from suffocation may result.
Carry out the installation work with reliability according to this 
manual for installation work.
Imperfection in installation leads to water leakage, electric shock, 
fire, etc.
Securely attach the protective covers for the outdoor unit 
connection cables and power cord so that they do not lift up after 
installation. If the covers are not properly attached and installed, 
the terminal connections may overheat, and fire or electric shock 
may result.
Carry out the installation work with reliability on the place that can 
bear the weight of this unit sufficiently. Insufficient strength leads 
to injury due to falling of the unit.
Switch off all supplies before accessing any electrical part.
Carry out predetermined installation work in preparation for strong 
wind such as typhoon, earthquake.
Imperfection in installation work may lead to accidents arisen from 
overturn, etc.
If refrigerant gas escapes during installation, ventilate the affected 
area. If the refrigerant gas comes into contact with sparks or naked 
flames, it will cause toxic gases to be generated.
