9. DRAIN SYSTEM OPTIONS
The conditioner comes with the two drain holes closed by plugs.
The conditioner is projected to use one of the three function options:
1)No drain connection. That way provides the most efficiency operation, but has splash noise, dripping of rain water or condensate water.
2)Rear drain, which provides a good efficiency for operation and very low splash noise, or
3)Drain pan, which captures the most condensate and does not have splash noise, but has lower efficiency operation. Both the rear drain and the drain pan can be connected to a hose and directed to a convenient location on the ground, or a suitable floor drain.
Install the draining system for the condensing water before positioning the unit in the cabinet. You must use one of the two existing systems, depending on how, and where the unit will be installed.
9.1DRAINING SYSTEM THROUGH THE REAR OUTLET
NOTE 
Remove the rear plug from the unit, and install the drain (item 6, page 4).
Pass a 5/8" (15,9 mm) plastic hose through the hole located on the rear of the cabinet.
The hose must be long enough to reach the rain water drain.
