and should be less than 110℃. The tip of the thermocouple is fixed by soldering when
measuring discharge pipe temperature .Furthermore, soldering point is covered with urethane
foam to prevent the effect of wind.
8 Air leakage test pressure
The pressure should be less than 2.847MPa{28kgf/cm2G}.
9.Oil Back and height of the 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.
10 Dust of compressor hermetic terminals
Compressor hermetic terminals should be mounted with specified cover in right way to prevent
dust entering, and should be used in direction which dust is hard to enter in.
11 Lead wire of compressor hermetic terminals
Measuring the temperature of hermetic terminals , lead wire should be resist to the temperature
and be clamped so as not in touch with the surface of compressor and pipe.

12 Start-stop frequency
The frequency should be less than 6 times per hour. Operating time from start to stop should
be more than 3 minutes. Stopping time should be more than 3minutes. But oil level should be met
to item 8. Suction and discharge pressure should balance completely before restarting.
13 Rate of rotational speed change
The rate of compressor rotational speed (acceleration) should be less than 133min-1/s, But if
The variable range is below 120min-1, rate can also be less than 600min-1 when rotational
Speed is reduced to avoid temporary over- current. The change of compressor rotational speed
is referred to chart 3.
14 Air and moisture in refrigerating system
The degree of vacuum in refrigerating system should be less than 133Pa (998×10－3mmHg) at
room temperature just before charging refrigerant. The quantity of water should be less than 0,15 ml
15 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.
(1) Prevent the impurities from entering into the enclosed unit system used . When the impurities
entered into the enclosed system, it will damage the moving mechanism parts and result
in the capillary depositing.
(1) Eliminate all system contaminants such as trichlorethylene, alkalies, soaps, oil, acids &
washing fluid used at machining heat exchanger and tubes.
16 Compressor vacuum operation
Compressor should never be operated while under vacuum. Otherwise, internal arcing can
cause damaging parts.
17 The compressor should be operated for more than 20 seconds within 15 minutes after charging
refrigerant into the system so proper lubrication results.

18 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
should flow back
flowing back compressor in any case. In normal condition the
overheat gas refrigerant compressor.
19 Process limitation of refrigerating system
(1) Be careful of avoiding oxide scale while soldering during assembly o
refrigerating system.
(for example: flow or fulfill dry nitrogen)
(2) The motor winding temperature should be less than 149℃and hermetic terminal body
temperature should be less than 177℃in process of manufacturing.
20 Apply for vehicle
The compressor should not be used on moving equipment such as
automobiles, trains, ships, etc.
20 Installation
The rotational axis of compressor should be kept vertical during operation. But in actual
application the axis incline must be within 5at all directions during operation.
21 Pipe vibration
The displacement of the pipes, which connect from the compressor to other parts of the refrigerate-
or systems, should be less than 0.8mm(1/32”)when the compressor is operating at allowable
rotational speed range and voltage range of rated ±10%.
Displacement in excess of 0.8mm(1/32”) will require changing tube length and/or routing.
22 Connecting tube design
In designing and routing tubing that connect from the compressor to the other parts of the air conditioner,
following should be considered.
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.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE
SYSTEM
PAGE:10/29
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 the
compressor 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, it will expedite the deterioration of
the oil and result in the capillary depositing and the reducin g 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.
(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. 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.
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.
(13) There should be adequate clearance between the under-surface of Push-Nut and the
upper surface of rubber grommets.
(11) Compressor mounting

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 acciden t 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.

SYSTEM
PAGE:14/29
(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.
(22) The lead wires should be connected to hermetic terminals without being touched on the surface of the
compressor.
(23) The quantity and kind of contamination (the process materials) in the cycle should be grasped and
managed. Carry on reliability test that input contamination a lot than anticipated contamina tion
quantity.
(24) To avoid water and impurity into he refrigeration system and make sure no leakage of refrigerant during the
operating course. It’s required to direct the erector and maintenance man of air-conditioner.
(25) Adjust the start-up torsion of the compressor to above 0.55Nm by inverter. Confirm and measure the start-up
current if change the parts and design.
