COMPRESSOR CRITERIA
1 Strictly observe the specification
The compressor should be used in specifications written in this “compressor specification” and
not be used in specifications outside it.. The main circuit must link up with fuse or breaker.
2 Source voltage
Specified inverter is linked up with compressor terminals . Applied voltage of this inverter
should be voltage specified in this “compressor specification”. Alternating voltage should never
be applied on terminals (for example：commercial alternating voltage of 1φ100V,200V,3φ200V).This
is because that if applied alternating current the direct current motor will demagnetize.
3 Operating voltage range
The compressor should be operated in the range of rated voltage ±10% , under standard condition
and overload condition of rated frequency (applied voltage to inverter).It must be satisfied
with item 5 ,6,7.
4 Operating temperatures and pressures
The operating temperatures and pressures of a compressor should be within the range shown in
the table 2 and graph 1.
5Oil Back and oil level
The oil should be returned continuously to the compressor and the structure of the refrigerating
system should not make oil stay in the system. The oil level in compressor should be satisfied
with chart 2.If not keep the oil level, the shortage will occur, and influence the reliability of
the compressor.(please check the oil level in the compressor with the sight glass which supplied
form SHEC.

14 Impurities in refrigerating system
（1）The weight of residue on the inside surface of the heat exchanger and tube should be
less than 0.01g/m2. But metallic dust should not be permitted in the system. This value means
the weight of foreign residue collected by filer paper after washing inside surface of the
heat exchanger tubes with R-11.
（2）Prevent the impurities from entering into the enclosed unit system used R410A. When the
impurities entered into the enclosed system, it will damage the moving mechanism parts and
result in the capillary depositing.
（3）Eliminate all system contaminants such as trichlorethylene, alkalies, soaps, oil, acids
& washing fluid used at machining heat exchanger and tubes.
15 Compressor vacuum operation
Compressor should never be operated while under vacuum. Otherwise, internal arcing can
cause damaging parts.
16 The compressor should be operated for more than 20 seconds within 15 minutes after charging
refrigerant into the system so proper lubrication results.
17 Liquid refrigerant return limitations
（1）Liquid refrigerant level in s-tank should be lower
than the top of s-pipe in s-tank.(see chart at right)
(2) There should not exist noise of the liquid refrigerant compression, current and vibrancy
increase. System can append the assistant stank or reduce the amount of refrigerant to
prevent from liquid refrigerant compression. Refrigerant system forbid liquid refrigerant
from flowing back compressor in any case. In normal condition the overheat gas refrigerant
should flow back compressor.

conditioner, following should be considered.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA
PAGE：11/30
Moving tubes to the moving parts; minimum clearance 12.7mm(1/2”)
Moving tubes to non-moving parts; minimum clearance 9.5mm((3/8”)
Moving tubes never touch to lead wire.
23 Avoid refrigerant migration
The refrigerant migration to compressor shell should be avoided during the heat pump water heater
system shut down periods, It’s suggested that the electric heating belt should be used around
the shell bottom when necessary.
24 Miscellany
（1）The compressor should be carried carefully to avoid drop, drag ,impact and should not apply
partial force on projection parts such as pipe, hermetic terminals, foot during carrying
and processing.
（2）The compressor should not be operated to form a vacuum and to absorb air. The compressor
only can run in one direction which according to lead routing wiring diagram. Never
reversion otherwise thecompressor will be in trouble.
（3）The compressor should not be left opened in the atmosphere for more than 5 minutes.
When the air entered into the unit system with refrigerant R410A, it will expedite the
deterioration of the oil and result in the capillary depositing and the reducing of
insulation resistance.
（4）Electric pulse should not be applied to compressor when it is in vacuum.
（5）The compressor should be kept in the place with low-dust, low-moisture.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA

（6）The compressor can’t be used in the place with corrosive atmosphere such as hot
spring and chemical warehouse. It should not be the structure often splash water on the
surface of the compressor forcibly.
（7） The trouble of cross valve, electromagnetic valve, defroster, refrigerant controller,
fan motor used in refrigerating system may cause compressor accident .So their reliability
should be ensured completely. Moreover, the way of design, manufacture, application of
refrigeration cycle with less-leak should be adopted.
（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.
(10) Temperatures within systems during stable compressor operation should not be less
than -35℃ to prevent wax precipitation from the oil.
11) The units of refrigerating system should be connected to earth.
（12）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 andvibration isolation and to prevent compressor from coming off its mount.
(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.
(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 isbelow -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.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA PAGE：14/30
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.
(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.
