Schematic diagram of installation spaces
2).Main body of the indoor unit The indoor unit should be installed horizontally and the demand of installation
space is shown in Fig. 2. To install an indoor un it needs 4 hanging rods, and each hanging rod should at
least withstand four times of the unit’s weight.

3). Drain hose
For easy drainage of the condensation water, the should be installed with a downward gradient. To avoid the
condensation, the connection pipe joint should be insulated with thermal insulation material. A water seal
should be employed as shown in Fig. 3 and the height of the water seal could be determined by the pressure
of the drain hose.
Drain hose is in negative pressure state: A = B

4). Refrigerant pipe insulation layer
To avoid condensation of drew and water leakage, gas pipe and liquid pipe of refrigerant should be insulated with
thermal insulation material and adhesive tape.
