3 Installation of outdoor unit
3.1 Check before installation
(1) Before installation, please check the power cord if it complies with the power supply
requirement on the nameplate. Make sure the power supply is safe.
(2) This air conditioner must be properly grounded through the receptacle to avoid electric shock.
The ground wire shouldn’t be connected with gas pipe, water pipe, lightning arrester or
telephone line.
(3) Maintain good air circulation to avoid lacking oxygen.
(4) Read this manual carefully before installation.
3.2 Selection of installation site

erect.
(2) Make sure the unit is not exposed to sun and rain. And the location can resist dust, typhoon and
earthquake.
(3) Please keep the unit away from inflammable, explosive and corrosive gas or waste gas.
(4) Make sure the location has space for heat exchange and maintenance so that unit can operate
reliably with good ventilation.
(5) ODU and IDU should stay as close as possible to shorten the length of refrigerant pipe and
reduce bend angles.
(6)
Select a location which is out of children’s reach. Keep the unit away from children.
