9CONDENSATE DRAIN CONNECTIONThe unit is supplied with a drain connection to connect the drainpiping. When installing condensate piping, follow theserecommendations: Condensate piping should slope downward in the directionof the condensate flow, with a minimum gradient of 1 in.per 100 inches. When multiple units are connected to a commoncondensate drain, ensure the drain is large enough toaccommodate the volume of condensate from all units. Itis also recommended to place an air vent in the condensatepiping to prevent any air locks. Condensate piping must not be installed where it may beexposed to freezing temperatures.1.5m~2mInsulatingmaterialDownward declivitylower than 1/100BendS shapeVP30Downward declivitylower than 1/100Put as deep as possible(about 10cm)A150714Fig. 16 - Condensate FlowELECTRICAL DATA Table 5—Electrical DataINDOOR FAN MAX FUSE CB AMPUNIT SIZE V-Ph-Hz FLA HP9K 208/230-1-60 0.09 0.073 Refer to outdoor unit installation instructions –Indoor unit powered by the outdoor unit12K 1 0.073LEGENDFLA - Full Load AmpsCONNECTION DIAGRAMSFig. 17 - Connection DiagramNotes:1.
