3.3 Water Outlet
Four condensed water outlets on the chassis for selection display as the follow figure:
While installing the outdoor unit, pay attention to the installation place and the drainage pattern;
if it’s installed at
the alpine zone, the frozen condensed water will block up the water outlet, please pull out the rubber stopper of
the reserve water outlet. If that still fails to satisfy for the water draining, please knock open the other two water
outlets, and keep the water
can drain in time. Pay attention to the knock the reserve water outlet from outside to inside, and it will be beyond
repair after knocking open, please pay attention to the installation place, lest cause the inconvenience. Please do
the moth proofing for the knocked out hole, to avoid the pest processing into and destroy the components.
4. Piping Installation
4.1 Piping connection
Various piping and wiring patterns can be selected, such as out from the front, the back, the side, and
undersurface, etc.
（
The follow display the locations of several piping and wiring knock-off interfaces

Cautions:
Side out pipe: please remove the L-shape metal plate, otherwise cannot wiring.
Back out pipe: Please wipe off the piping support rubber blanket beside the inner outlet pipe cover of the machine while back side
getting out pipes.
Undersurface outlet pipe: the knock out should from inside to outside, and then piping and wiring through this.
Pay attention to the piping the fat connecting pipe should out from the largest hole, otherwise the pipes will be rubbed. Please do the
moth proofing for the knocked out hole, to avoid the pest processing into and destroy the components.
