Pipe Connection - Midea LRSJF-V120 Technical Manual

Caution:
 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.
