OPERATION MANUAL

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:

①The input value of the refrigerant tank is closed——open the valve will help solve the problem.

②The connecting hose between the recovery unit and refrigerant tank is stuck——close all the valves and replace the

connecting hose.

③The 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

recovery.

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.

Page 6: REFRIGERANT RECOVERY UNIT OPERATING MANUAL

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.
