(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 R290, 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.
