If it is not possible to completely charge the unit
with the proper amount of refrigerant, you can do
a additional charging after installing the units. At
that time, refrigerant should be recharged in the
liquid state a little at a time using the wide tube
service port, and the air conditioner should be

Charging the unit with a large amount of
refrigerant at once may damage the compressor.
Always charge the unit at a constant charging rate
of about 100 g.
