(14) SHEC will not take any responsibility against accident that is caused by
the accessories equipped by yourselves.
(15) The hermetic terminals of compressor should not be inserted slantingly and not
be applied twisting force after inserting so as to avoid reducing of terminal
fixed force.
(16) The pipe and hermetic pens attached to the compressor should not be bent.
(17) The dropped compressor can
’
t be used anymore.
(18)
Compressor can be used when ambient temperature is higher than -10
℃
. Confirm the start-
up
of compressor if the temperature of compressor surface is below -10℃. Heat up
compressor to reach the temperature higher than -10℃ with heater if the ambient
temperature is below -10℃.
(19)
Set a thermistor on the case cover of compressor to prevent from accident of leakage of
refrigerant.
The thermistor can stop the operation of compressor when compressor in abnormal
temperature. The lead wires of thermostat is enveloped with tube, as same as that of the terminals,
to avoid directcontact with the compressor and pipe.
(20) The compressor should not be splashed with water intentionally.
Prevent moisture from entering into the enclosed unit system. When the moisture
entered into the unit of the refrigerant R410A, the refrigerant oil and the organic
compound material presented in the hermetic motor will possibly decompose on the
affecting of water. It will result in the capillary depositing and the reducing of
insulation resistance.
It is necessary to install a dryer to dehumidify the residual moisture mixed in the
refrigerant in the cycling system. The specially defined molecular-sieve dryer is
advised.
