HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM
PAGE:12/30
(8) The main electric circuit should be equipped with fuse or breaker.
(9) Refrigerant should be charged from the end of condenser of refrigerating systems. Never
Charge refrigerant to the compressor directly.
The refrigerant should always be charged in liquid state. When the refrigerant is charged in gas state,
The percent component will possibly be changed. Do not recharge with the remaining refrigerant in the system when
leakage happened. Because the percent component of the refrigerant in the unit system had possibly been changed.
(10) Temperatures within systems during stable compressor operation should not be less than
-35 to prevent wax precipitation from the oil.
℃
(11) Compressor mounting
Rubber grommets are designed soft to provide the noise isolation and to lessen vibration
Energy transmission. Stud bolt should be designed to provide sufficient clearance for noise and vibration isolation
and to prevent compressor from coming off its mount.
(12)The units of refrigerating system should be connected to earth.
(13)There should be adequate clearance between the under-surface of Push-Nut and the
upper surface of rubber grommets.
(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.
