COMPRESSOR CRITERIA
1 Strictly observe the specification
The compressor should be used in specifications written in this "compressor specification" and
not be used in specifications outside it.. The main circuit must link up with fuse or breaker.
2 Source voltage
Specified inverter is linked up with compressor terminals . Applied voltage of this inverter should
be voltage specified in this "compressor specification". Alternating voltage should never be applied
on terminals (for example：commercial alternating voltage of 1φ100V,200V,3φ200V).This is because
that if applied alternating current the direct current motor will demagnetize.
3 Operating voltage range
The compressor should be operated in the range of rated voltage ±10% , under standard condition
and overload condition of rated frequency (applied voltage to inverter).It must be satisfied
with item 5 ,6,7.
4 Operating temperatures and pressures
The operating temperatures and pressures of a compressor should be within the range shown in
the table 2 and graph 1.
5 Oil Back and height of the oil level
The oil should be returned continuously to the compressor and the structure of the refrigerating
system should not make oil stay in the system. The oil level in compressor should be satisfied
with chart 2.If not keep the oil level, the shortage will occur, and influence the reliability of
the compressor.(please check the oil level in the compressor with the sight glass which supplied
form SHEC.
