4.1 Installation Requirements
4.1.1 Layout Principles
The layout principles are as follows:
● 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 dierence, 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
gure, is a sign of a tilt, indicating that the scale of the pipe
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
oor of the equipment room should be routed in
tubes, between which sealing measures
(restop putty recommended) are
taken.
