batteries.
• Remove the batteries from the remote control if the sys-
tem is not going to be used for a long time.

If the actual pressure are higher than shown, the system is most likely over-charged, and charge
should be removed. If the actual pressure are lower than shown, the system is most likely under-
charged, and charge should be added. The air conditioner is now ready for use.
