Explain :

Indicate that the compressor must be attached with cooling or limited suction temperature.

Indicate that the compressor must be attached with cooling temperature and the maximum suction superheat degree should be less than 20 DEG C.

Indicate that the compressor must be attached with CIC system.

When the frequency is 60Hz, the refrigerating capacity is increased by 20%.
