1. Once the position of the drain pipe has been selected, remove the corresponding perforation
indication from the unit housing.
2. Select the position of the piping hole/orifice to be drilled in accordance with the position of the drain
pipe selected for the application. The position of this pipe hole should be slightly smaller than that of
the mounting frame on the wall.
3. Drill a hole of 2 3/16 inch or 2 3/4 inch (24K unit) diameter for the insertion of the selected outgoing
pipe. In order to obtain efficient draining, the outgoing hole should be slightly pitched during drilling at
a gradient of 5-10° (shown below).
4. Insert an insulating sleeve inside de hole/orifice in the wall to prevent damages to the connection
piping and to the wiring that will pass through this drilled orifice.
Piping can be connected in right direction, right/rear direction, left direction, left/rear
direction.
Refrigerant piping in the indoor unit
Remove covers and caps from the piping.
NOTICE
1. Be sure to connect piping appropriately to the port in the indoor unit. If it is not centered
correctly, the flare nut will not be able to be tightened as it should. If tightening of the nut is
forzed, the fitting threads will be damaged.
2. Do not remove the flare nut until ready to connect the connection piping and avoid the entry
of pollutants into the piping system.
NOTICE
1. When an insulating sleeve is not utilized, it will then be necessary to drill a completely straight hole in
the wall. If this hole is not straight and uniform, it could initiate water leaking through condensation as
well as damages to the property.
2. If an insulating sleeve is not mounted in the orifice, the wiring between the indoor unit and the outdoor
unit could suffer damage as a result of the loss of electric current to the grounding cables.
