The layout principles are as follows:

All units must be securely grounded. The ground resistance must comply with
local laws and regulations to prevent poor grounding.
Power cables and signal cables must be separately routed with a spacing
greater than or equal to 30 mm between them, and they must not be routed
in the same pipe. Electric and ELV cables must be bound separately.
Before connecting cables to ports, leave enough slack to reduce the tension
on the cables and prevent poor cable connections.
Cable colors in this document are for reference only.
If the outdoor unit is placed higher than the indoor unit, the vertical distance
between them should be less than or equal to 30 m. An oil trap should be
installed every 5 m to 6 m in the vertical direction along the gas pipe and an
inverted trap for the inlet and outlet of the outdoor unit to ensure system
reliability.
If the indoor unit is placed higher than the outdoor unit, the vertical distance
between them should be less than or equal to 8 m.

● When calculating the height difference, the compressor base is regarded as
the baseline for the indoor unit, and the condenser top is regarded as the
baseline for the outdoor unit.
● The inverted trap should be higher than the top copper pipe of the
condenser.
● In the figure,
tilting is at least 1:200. The pipe tilting direction should be consistent with
the hypotenuse of the right triangle.
● If the indoor unit is placed lower than the outdoor unit, add an inverted U-
shaped trap.
● Pipes through the wall or floor of the equipment room should be routed in
tubes, between which sealing measures (firestop putty recommended) are
taken.
