We recommend that this air-conditioner be installed properly by qualified installation technicians in accordance 
with the installation instructions provided with the unit. 
Before installation, check if the voltage of the power supply in your home or office is the same as the voltage 
shown on the nameplate. 

You must not carry on any transformation to this product, otherwise, it may possibly 
cause such consequences as the water leakage, the breakdown, the short-circuit, an 
electric shock, fire, etc.
The work such as tube line welding, etc. should be carried out far away from the 
flammable explosive material vessels, including the air-conditioner refrigerant, to 
guarantee the security of the site.
To protect the air-conditioner from heavy corrosion, avoid installing the outdoor unit 
where salty seawater can splash directly onto it or in sulphurous air near a spa. Do 
not install the air-conditioner where excessively high heat-generating objects are 
placed. 

Never use gasoline or other inflammable gas near the air-conditioner, which is very 
dangerous. 

Do not turn the air-conditioner on and off from the power main switch. Use the 
ON/OFF operation button.
Do not stick anything into the air inlet and air outlet of both the indoor and outdoor 
units. This is dangerous because the fan is rotating at a high speed. 
Do not cool or heat the room too much if babies or invalids are present.
