Do not touch the fan with hands or other objects.
Do not lean it more than 45, and do not lay it sidelong.
Make concrete foundation according to the specifications
of the outdoor units.
Fasten the feet of this unit with bolts firmly to prevent it
from collapsing in case of earthquake or strong wind.
5. Drainage Pipe Installation
Install the drainage pipe as shown below and take
measures against condensation. Improperly installation
could lead to leakage and eventually wet furniture and
belongings.
5.1 Installation principle
• Ensure at least 1/100 slope of the drainage pipe
• Adopt suitable pipe diameter
• Adopt nearby condensate water discharge
5.2 Key points of drainage water pipe
installation
1. Considering the pipeline route and elevation.
• Before installing condensate water pipeline, deter-
mine its route and elevation to avoid intersection
with other pipelines and ensure slope is straight.
2. Drainage pipe selection
• The drainage pipe diameter shall not small than the
drain hose of indoor unit
• According to the water flowrate and drainage pipe
slope to choose the suitable pipe, the water flow-
rate is decided by the capacity of indoor unit.
