3.2 Operating Instruction
3.2.1 Check Before Operation
(Only qualified service personal should operate this unit , may require the user to be
licensed for some countries )
■Working-spot should have good lighting and Atmospheric conditions.
■Make sure the charging refrigerant oil from the oil tank is the same as the type
indicated on the nameplate.
■ Make sure with the correct voltage as the same as nameplate.
3.2.2 Oil Charging Process
3) Open the oil charging valve , switch on the oil pump to start to charge the oil.
4) Running the compressor to review if the oil level . pressure . oil temperature is under
normally conditions, and do the adjustment if necessary.
5) Remove the oil tank .oil pump and outlet hose if everything is fine, wipe out the rest
oil inside hose and pump. Pack them with sealed plastic bag ,then keep the
compressor running again.

1) Clean the inlet and outlet hose to protect the oil mix,connect to the oil pump,then
insert the inlet hose to the tank.
2) Switch on the pump for suction oil and discharge the air from the inlet hose and
pump body,then switch off the pump once make sure no air inside(Judgment
Principle: The discharged oil has no foam or obvious air discharge noise, proves that
the air has been discharged ). Connect the outlet hose to the oil charging valve of
compressor.
3) Open the oil charging valve , switch on the oil pump to start to charge the oil.
4) Running the compressor to review if the oil level . pressure . oil temperature is under
normally conditions, and do the adjustment if necessary.
5) Remove the oil tank .oil pump and outlet hose if everything is fine, wipe out the rest
oil inside hose and pump. Pack them with sealed plastic bag ,then keep the
compressor running again.

4. Maintenance
Before/during checking process, make sure the installation is disconnected from
the power supply.
WARNING
Don’t touch the pump while the unit is very hot after running long-time.
WARNING
To ensure the long-life and performance of oil pump, it should need to use clean .pure
refrigerant oil . Be sure to check first when the oil doesn’t be used for a long time.
Problem Cause Action
Solution pump
Isn’t operating
At all
1.Power doesn’t reach the pump
2.The voltage isn’t correct
3.The thermal protector works
4.The temperature is too low
5.The pump body locked due to the dirt.
1.Check the power and switch
2.Make sure to keep the input voltage
within rated voltage ±5%
3.Check the thermal protector
4.Increase the invironment temperature
5. Troubleshooting
Flow rate is too
Small or cann’t
Pump anymore
1.The inlet hose or filte blocking
2.The system has the air
3.The outlet hose block
4.The oil level is too low
5.The system pressure is too high
6. Pump stored for a long time
1.Clean the inlet hose and filter
2.Discharge the air
3.Keep the outlet hose unblock
4.Check the inlet hose is under the oil
Level or not
5.Solve the problem of high pressure
6. Pour a little oil from the pump inlet port
Pump runs with
high noise
1. too low oil level
2. unreasonable hose size
3. the dirt inside to pump
4. the system has the air
5. pump inner body damaged
1.check the inlet hose is under the oil
level or not
2.adjust the hose size
3.repair the pump
4.discharge the air
5.repair the pump ,change the parts
Pump
temperature
is too high
1.Work pressure is more than
max. pump pressure
2. No enough fan cooling
3. The invironment temperature is
too high
4.Poor ventilation
1.Read the manual carefully,re-select
the model
2.Check the motor fan runs well or not
3.Decrease the invironment temperature
4.Improve ventilation
When the working pressure exceeds 5MPa, please stop charging and check
whether the oil outlet pipeline is blocked.(R6)
WARNING
3.2.3 During Operation
1) R4 Oil Charging Pump
When the pressure in the pump is too high and the R4 motor cannot
operate normally at the rated speed, the oil return valve of the pump can
be opened and then closed after the speed is normal, thus achieving the
effect of instant pressurization.
2) R6 Oil Charging Pump
When the charging pressure exceeds 2.5MPa, the pipeline safety relief
valve opens. Oil flows back to the oil inlet through the return pipe to reduce
the pressure of the outlet pipe.
When the oil outlet pressure exceeds 5MPa, please stop charging and
check whether the oil outlet pipeline is blocked.
