3.2.2 Outdoor Unit Installation
(1) If the outdoor unit is installed on a solid ground such as concrete, use M10
screw bolts and nuts to secure the unit and make sure the unit stands erect
and level.
(2) Do not install it on top of the building.
(3) If it vibrates and causes noise, please add rubber cushion between the
outdoor unit and the installation base.
(4) When the outdoor unit is in heating or defrosting, it needs to drain water.
When installing the drain pipe, plug the accompanied drainage connector to
the drainage hole on the chassis of the outdoor unit. Then connect a drain
hose to the drainage connector (If drainage connector is used, the outdoor
unit should be at least 10cm from the installation ground). See the figures
below.

3.2.3 Connection Pipe Installation
3.2.3.1 Installation Notice and Requirement on Connection Pipe
① Indoor unit adopts special joints that can't be disassembled. The installation
method is the same as the unit with ordinary joints. However, because the
joints can't be removed, if the connection is not good and causes leakage, the
joints need to be cut and welded again for replacement.
② The removal-proof screw nut must be connected to the indoor unit.
