SYSTEM DESIGN LIMITATIONS
1.1 Power source and Voltage
Voltage applied to hermetic terminal should be within the range mentioned
in this specification.
In the case of three phase, the phase imbalance should be within 3% among
the compressor terminals. The phase imbalance should be calculated
according to the follow formula.
(V)max-(V)mean
the phase imbalance= 100%
(V)mean
(V)max:Maximum voltage among the three terminals.(V)
(V)mean:average voltage among the three terminals.(V)
1.2 Operating Temperatures and Pressures
The operating temperatures and pressures of the compressor should be within
the range shown in the table 2 and graph 1.
1.3 Operating and Shut-off Period
The compressor should be operated continuously at least for 5 minutes after
being turned ON.
3 minutes shut-off time should be ensured at least until restarting.
1.4 Oil Back and height of the oil level
Oil should be returned continuously to the compressor and not kept in the
refrigeration system.
Oil level of compressor should be higher than 7.5 mm from the lubricating piece
fixed on the end of the crankshaft.
Compressor must not be started operated under a dual-layer separate status.
However, in case of foaming situation, the height of this foam does not mean
the height of the oil level.
If you do not keep the oil level, the oil shortage will occur, and influence the
reliability of compressor.
(Please check the oil level in the compressor with the sight glass we supply.)

1.5 Discharge pipe temperature
Discharge pipe temperature is measured at a distance 300mm from the surface of compressor
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.

1.6 Temperature of Shell Bottom
The Temperature of compressor shell Bottom must be 6 degrees higher than the corresponding saturated
temperature of discharge pressure under normal operating conditions.
1.7 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.
1.8 Allowable Incline
The allowable incline should be less than 5° during operation.
1.9 Pipe Vibration
The displacement of the pipes, which connect from the compressor to otherParts of t
he refrigerator systems, should be less than
0.8mm(1/ 2”)when the compressor is operating at rated frequency +10Hz/ -10Hz and voltage range of rated ±10%.
Displacement in excess of 0.8mm(1/ 2”) will require changing tube length and/or routing.
。
1.10 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( /8”)
Moving tubes never touch to lead wire.
2.
PROCESS LIMITATIONS
2.1 The degree of vacuum in the refrigerating system should be less than 20Pa
{150×10- mmHg}at room temperature just before charging refrigerant.
The quantity of water should be less than 0.2ml.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM
PAGE：9/25
2.2 Prevent moisture from entering into the enclosed unit system. When the moisture
entered into the unit, 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 device for drying and
filtering of R-290 is advised.
2. The weight of foreign particles on the inside surface of the heat
exchanger tubes should be less than 0.05g/m2.
Metallic dust should not be permitted to enter the refrigerating system.
This value means the weight of foreign particles filtered after washing
inside surface of the heat exchanger tubes with R-11.
Prevent the impurities from entering into the enclosed unit system . When the impurities
entered into the enclosed system , it will damage the moving mechanism parts and result
in the capillary
depositing.
2.4 Eliminate all system contaminants such as trichlorethylene, alkalies,soap ,acid ,oil & washing fluid used at machining the heat
exchanger tubes.
2.5 Purge parts with dry nitrogen or dry air to remove remains in parts
(dust, detergent，etc.) before assembly of system.. Time for purging :over one
second for pipe ;over three seconds for heat exchanger . Purging pressure:
0.9±0.1MPaG.Dew point of dry air: Below-20°C.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM
PAGE：10/25
Dry nitrogen should be charged in compressor before assembly of system.
Welding should be finished within one minute after charge of nitrogen. Dry nitrogen
needs to be charged again and weld if over one minute. Always purge the compressor with
dry nitrogen during assembly of system .
2.6 The motor winding temperatures should be less than 149℃ in process of
manufacturing the
refrigerating system. The temperature of the hermetic terminal body should be less than 177℃.
2.7 The compressor should be operated for more than 20 seconds within 15 minutes after charging
refrigerant into the system so proper lubrication results.
2.8 The manufacturing process of refrigerating system must comply with the regulations related to flammable refrigerants, since
R290 is flammable refrigerant.
2.9 Explosion-proof unit should be used in the system.
2.10 Refrigerant R-290 99.9% in purity should be used for apparatus. 99.95% is recommended, if possible.
.
MISCELLANY
.1 The pipe and hermetic pins attached to the compressor should not be bent.
.2 The compressor should never be operated while under vacuum；otherwise,
internal arcing can cause damaging parts.
. The compressor should not be operated to form a vacuum and to absorb
air.
.4 The compressor should not be left opened in the atmosphere for more than
5 minutes.
When the air entered into the unit system, it will expedite the deterioration of the oil
and result in the capillary depositing and the reducing of insulation resistance.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM
PAGE：11/25
.5 The electric pulse should not be applied to the hermetic terminals when
the compressor is under vacuum.
.6 The compressor should be kept in the clean place with low-
moisture.
.7 The compressor must not be applied for transportation equipment, such as
automobiles, trains, ships, and others.
。
.8 The compressor should not be splashed with water intentionally.
.9 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.
.10 Refrigerant should be charged from the end of condenser of refrigerating
systems. Never charge refrigerant to the compressor directly.
.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 first starting voltage supplied to the refrigerating system should be more than the starting
voltage mentioned TABLE 1(page ).
The refrigerant can not dissolve in the oil at the beginning because of the high viscidity of the oil.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM
PAGE：12/25
.1 The compressor should be kept out of the corrosive atmosphere such as in a chemicals storage, beside
a hot spring and so on.
.14 The lead wires should be connected to hermetic terminals without being touched on the surface of the
compressor.
.15 The fuse or/and breaker should be equipped in the main circuit.
.16 The oil should be returned continuously to the compressor and not stayed
in the refrigerating system.
.17 There should be adequate clearance between the OD26-under-surface of
Bolt -Head and the upper surface of rubber grommets.
.18 To avoid water and impurity into the refrigeration system and make sure no leakage of
refrigerant during the operating course. It’s required to direct the erector and maintenance
man of heat pump water heater.
