58 Installation
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
Offering four directions to connect pipes and wirings for meet a variety of installation request.
Right side pipe connection: please remove the L-shape metal plate, otherwise cannot wiring.
Back side pipe connection: Please wipe off the piping support rubber blanket beside the inner outlet pipe cover
of the machine while back side getting out pipes.
Bottom side pipe connection: 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.

Note: When the total equivalent piping length of liquid + gas side is ≥90m, it must increase the size of air side main pipe. Besides,
according to the distance of refrigerant pipe and the over matched state of indoor unit, when the capacity is decreasing it still can
increase the gas side main pipe size.
