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.
