(21) Use the refrigerant of specified brand. When the refrigerant not specified used,
it will
possibly cause trouble of the performance and reliability of the compressor
by the impurities in the refrigerant.
(22) The lead wires should be connected to hermetic terminals without being touched
on the
surface of the compressor.
(23) Be careful of avoiding oxide scale while soldering during assembly of
refrigerating
system.(for example: flow or fulfill dry nitrogen)
(24) The quantity and kind of contamination (the process materials) in the cycle
should
be grasped and managed. Carry on reliability test that input contamination
a lot than anticipated contamination quantity.
(25) To avoid water and impurity into he refrigeration system and make sure no
leakage of
refrigerant during the operating course. It’s required to direct the
erector and maintenance man .
(26) The start-up current and torsion of compressor
Adjust the start-up current of the compressor to get enough torsion by
inverter. Confirm and measure the start-up current if change the parts and
design.
