HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE
SYSTEM
PAGE:12/29
(12)The units of refrigerating system should be connected to earth.
(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 thermistror 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 direct contact 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.
