 ❚ INSTALLATION PRECAUTIONS
 WARNING
 •
The system is for domestic and residential use.
If used in severe environments, such as an engineering workplace, the equipment may 
function poorly.
 •
The system must be installed by your dealer or a qualified installer.
It is not advisable to install the system by yourself, as faulty handling may cause 
leakage of water, electric shock or fire.
 CAUTION
 •
Do not install it where flammable gas may leak.
Gas leaks may cause fire.
 •
Make sure that an earth leakage 
breaker is installed.
If you do not install an earth leakage 
breaker, you may get an electric shock.
 •
Make sure to install the drain hose 
properly so that all the water is drained 
out.
Improper installation may lead to water 
drop in the room resulting in wet furniture.
 •
Make sure that the system has been properly earthed.
Earth wire should never be connected to a gas pipe, water pipe, lightning conductor 
or telephone earth wire. Improper installation of the earth wire may cause an electric 
shock.
