Installation and Commissioning Ø Installation Sample

Installation and Commissioning Ø Installation Space Diagram l Integral Type Note: during installation, in order to meet normal requirements on heat elimination, please keep certain distances at four sides of the unit.

Installation and Commissioning Ø Installation Space Diagram l Split Type (Outdoor Unit) Note: during installation, in order to meet normal requirements on heat elimination, please keep certain distances at four sides of the unit. Installation space of the indoor unit is the same as that of the integral type unit.

Installation and Commissioning Ø Condensate Drainage Normal drainage depends on properness of installation of the drain pipe. It should be installed with a certain inclination to facilitate drainage. Connectors should be thermally insulated to prevent dewing. Besides, it should be water sealed as shown in the figure below. Height of the water seal should be decided by the inside pressure. Drain pipe Under negative pressure: A = B≥P/10+20(mm) Housing Under positive pressure: A≥ 30 mm，B≥P/10+20(mm) P is the absolute pressure (Unit: Pa) Channel iron Base Water seal
