Notice means that mis-operation can do harm to the unit and lower the performance of the unit,
or even make the unit unable to work properly.
For your better understanding of the security labels in this manual, we have listed the
content of these security labels for your reference.
Before starting the equipment, be sure that it is well grounded.
While using electrical wire, the wire must be well connected and grounded.
Only a qualified electrician should do the wire connection according to
the technical standard and circuit diagram.
Be sure the power is off before examining or repairing the recovery unit.
If the original power supply cord is damaged, choose carefully for the replacing one,
or you may directly buy from us.
When the unit breaks down, be sure the power is off before you do any operation.
Please consider the current capacity of power supply, ammeter, electrical wire and socket.
Use only authorized refillable refrigerant tanks. It requires the use of recovery tanks
with a minimum working pressure of 4.0MPa(580psi). Do not overfill the recovery tank .Tank
is full at 80% capacity. There should be enough space incase liquid expansion. Overfilling
of the tank may cause a violent explosion.
Always wear safety goggles and protective gloves while working with refrigerants to
protect your skin and eye from refrigerant gases or liquid. Avoid getting in touch with
caustic gas or liquid.
Be sure that the room where you are working is thoroughly ventilated.
Be sure the unit is working under the right power supply.
When using an electric cable it should be a minimum 2.0mm 2 AWG and no longer
than 7.5 meters, or it may cause the voltage drop and damage the compressor.
The input pressure of the unit should not exceed 2.6MPa(377psi).
The unit need to be laid horizontally, otherwise it will lead to unexpected vibration,
noise or even abrasion.
The ventilation opening of the unit must not be blocked.
If the overload protector pops, reposition it after 5 minutes.
There is a safe valve with the recovery unit, when the high pressure switch damaged and
internal pressure above 4.0 MPa(580psi), safe valve will release pressure to ensure
1. Do not mix different refrigerants together in one tank, or they could not be separated or used.
2. Before recovering the refrigerant, the tank should achieve the vacuum level: -75cmHg(29.6inHg), which is for purging
non-condensable gases. Each tank was full of nitrogen when it was manufactured in the factory, thus the nitrogen should be
evacuated before the first use.
3. The input and out valves must be closed, the recover/self-purge valve to position "self-purge",
the input and output fittings should be covered with protective caps when the unit is not in operation .The air moisture is harmful to
the recovery and will shorten the life span of the unit.
4. A filter drier should always be used and should be replaced frequently. And each type of refrigerant must have its own filter. For
the sake of ensuring the normal operation of the unit, please use the filter specified by our company. High quality filter drier will
bring high quality services.
5. Special-caution is needed when recovering from burnt system, and two dry filters are needed.
6. The unit has an Internal High Pressure Shut-Off Switch. If the pressure inside the system is above 3.0MPa (435psi), compressor
will automatically shut off and the red light turns on. To restart the compressor, please lower the internal pressure and press the start
button, then turn on the power to restart the compressor.
When High Pressure Protection is initiated, please find out the cause and deal with it before restarting the unit.
Cause of High Pressure Protection and Trouble Shooting:
The input value of the refrigerant tank is closed——open the valve will help solve the problem.
The connecting hose between the recovery unit and refrigerant tank is stuck——close all the valves and replace the
connecting hose.
The temperature of the refrigerant tank is too high, pressure is too high——give it some time to cool down and the
pressure will come back to normal.
7. The unit has an Internal Low Pressure Shut-Off Switch and Bypass Switch. When the Bypass Switch is on“Auto”, if the
pressure inside the system is below -8inHg~ -12inHg(-20.3cmHg~-30.4cmHg), the unit will automatically shut off and the Green
Alarm Light turns on.If it needs restart the compressor, please increase the input pressure above 0.08MPa(11psi) or turn the
Bypass switch on manual and then press the start button.
8. The recovery unit must be used together with a refrigeration storage tank which is equipped with a float level sensor, before
starting the unit, please connect the 80% O.F.P. cable with the float level sensor on the tank. In the process of recovering, if the
recovered liquid refrigerant reaches 80% capacity of the tank, the recovery unit will automatically stop and the Red Alarm Light
turns on. Please change a empty tank before restart. Meanwhile, a electronic scale is required to monitor the whole process of
9. In order to gain maximum recover speed, a hose with inner diameter bigger than 4mm is recommended and the hose should
better be shorter than 1.5m.Too narrow or too long hose will reduce the recovery rate.
10. While recovering large amounts of liquid, please use the Push/Pull Mode.
(See Push/Pull Mode operation on Page12)
11.After recovering, make sure there is no refrigerant left in the unit. Read the Purge Operation carefully. Liquid refrigerant
remained in the unit may be expanded and destroy the components.
12. If the unit is to be stored or not used for any length of time, we recommend that it be completely evacuated of any residual
refrigerant and purged with dry nitrogen.
13. Connection hose with check valve is recommended, it can prevent refrigerant lose.
14. The intake port is equipped with filter screen, please wash it frequently to keep it clean.
15. The Low Pressure Gauge shows the pressure of the intake port of the compressor and the High Pressure Gauge shows the
pressure of the outlet port of the recovery unit.
