The float switch will shut down the cooling in the event of a 'high water-level' beingdetected in the drain tray. The outlet connection from the pump is positioned on the pipe exit panel and is 200 mmabove the room-side surface of the ceiling as shown below.Superior ceilingIndoor unitPump outletIsolate drain pipeUnderceiling or ceilingDrain pipe supportat 1,5 m step distancesCondensate pipes should be run in 15 mm o.d. hard plastic or copper tube and supported at 1.5 mêtre intervals - orcloser. It is important to avoid piping which can sag between supports, as this will create traps and prevent the waterrunning away. Drain pipes should be sloped downwards in the direction of flow and should fall at an angle of 2% orsteeper if possible. Condensate pipes MUST be insulated in order to prevent sweating and possible damage to ceilingtiles.The drain pipe should be run to a suitable drain or disposal tank with a pump.If there is sufficient space above the ceiling, the condensate drain pipe may be raised to a position 500mm above theceiling surface in order to allow a greater fall (or longer length of pipe).It is important to keep the length of this rising pipe as short as possible (near vertical) as the water inside it will run backinto the unit when the pump stops. If too much water is allowed to flow back there will be a problem of short-cycling ofthe high level float switch.Isolate drain pipe (minimum 1% incline)Superior ceilingPump outletIndoor unitDrain pipe support at 1,5 mstep distancesUnderceiling or ceilingIn case the drain pipe is connected to a tank with a pump, to avoid the water flow-back into the unit whrn the pump isnot working, the drain pipe should be 100mm above the ceiling surface.53
