2 The appearance of theunits that you purchase might be slightly different from the ones described inthe GUIDE , but it does not affect your proper operations and read carefully the sections corresponding to the specific model youchoose, and keep the GUIDE properly so as to facilitate your reference at *Selection of INSTALLATION positions for indoor unit** To be installed at the position where the air delivered from the unit can reach every corner ofthe room;* To avoid being affected by the outdoor air;* To avoid blockage to the air inlet or outlet of the unit;* To avoid too much oil smoke or steam;* To avoid possible generation, inflow, lingering or leakage of flammable gases;* To avoid high-frequency facilities (such as high frequency arc welders, etc.)

3 ;* To avoid the places where acid solutions are frequently used;* To avoid the places where some special sprayers (sulfides) are frequently used.* Not to install on top of the musical instruments,TV,computer appliance.* Not to install a fire alarming device near the air outlet of the unit (during operation, the fire alarmdevice might be erroneously triggered by the warm air from the unit); INSTALLATION & REPAIR GUIDES plit Wall- mounted Air Conditioner* Height limits of indoor and outdoor units.* Either the indoor unit or the outdoor unit can be higher, but the height difference must comply the stated requirements.* Try to reduce the bending of the piping line as much as possible so as to avoid possible negative impacts upon theperformances of the unitoutdoorunit5m(16'5") :If there are some additional function devices to install on the air conditioner,Besure add to the INSTALLATION space for the function 100mm(4")Left side: 150mm(6") and above from wallRight side: 150mm (6")and above from wallCeilingWall hanging plateground2300mm(7'6") and above* Make sure of enough space for INSTALLATION and maintenance.

4 * To take into consideration the operational convenience and safety in INSTALLATION , it is recommendedto ensure enough space between the unit and the *Selection of INSTALLATION positions for outdoor unit** To install the outdoor unit at the places which can stand the load of the machine weight and will not cause big vibrations and noises;* To install the unit at the places not to be exposed to rain or direct sunshine, and the places with good ventilation;* The noises generated from the unit will not affect the neighboring places;* Do not install the unit on non-metal frame;* Not to install the unit at the places where there might occur the generation, inflow, stay orleakage of inflammable gases;* Pay attention to the drainage of the condensed water from the base plate during operations;* To avoid the air outlet being directly against the space requirements around the outdoor unit1.
