Issue 04 (2022-12-15)
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 set
every 5 m to 6 m along the vertical gas pipe to ensure system reliability, and
an inverted trap should be set at the inlet and outlet of the outdoor unit.
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.
The equivalent length of the one-way pipe should be equal to or less than
100 m.

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