product is started, refrigerant must be sucked from the needle valve after the
expansion valve. The refrigerant cylinder should be upside down or tilted (more
than 45°). Ensure that the refrigerant is slowly sucked into the compressor,
preventing the compressor from being damaged due to slugging.
Refrigerant has been filled in the outdoor unit based on the standard pipe length
before delivery. If the pipe between the indoor unit and outdoor unit is less than
or equal to 10 m, no extra refrigerant needs to be filled.
For a 5 U rack-mounted smart cooling product with a low ambient kit, the
amount of refrigerant to be filled is the amount of refrigerant to be filled for a 5 U
rack-mounted smart cooling product without a low ambient kit plus 2 kg.
If the pipe between the indoor unit and outdoor unit is longer than 10 m, add
refrigerant to the system to ensure normal system operation. The following table
lists the amount of refrigerant to be added for each 1 m increase in the length of
the pipe connecting the indoor and outdoor units.
