NOTE
• The amount of refrigerant charged is based on the standardized pipe length. If the installed pipe is longer than
the standard length, extra refrigerant needs to be added.
• Reliability cannot be guaranteed if the pipe is longer than the maximum length.
• It may cause reliability, performance, noise, and vibration problems, if piping limitations are not met. Ensure
there's a minimum piping length, by making loops if necessary, if the indoor unit and outdoor unit are too close.
