3. 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(-29.6psi), 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 switch should be at "o"· Position before operation. All the valves must be closed, the input an output
fittings should be covered with protective caps when the unit is not in operation. The air moisture is
harmful to the recovery result 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 filter is needed.
6. The unit has an Internal High Pressure Shut-Off switch. lf the pressure inside the system is above rated
shut-off pressure (see specification), compressor will automatically shut off and the high pressure alarm
light will turn on. To restart the compressor, please lower the internal pressure (Output gauge indicates
lower than 30 bar/435.1 PSI) , after the high pressure alarm light turn off, hit the Reset 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:
a. The input valve of the refrigerant tank is closed--open the valve will help solve the problem.
b. The connecting hose between the recovery unit and refrigerant tank is stuck--close all the valves and
replace the connecting hose.
c. The temperature of the refrigerant tank is too high, pressure is too high--give it snore time to cool
down and the pressure will come back to normal.
7. This unit can be used together with a float level sensor. Please connect the recovery unit and the tank
with the 80% O.F.P. cable. lf the liquid refrigerant reaches 80% capacity of the tank the recovery
unit will automatically shut off and the Red Alarm Light turns on. Before restart please change a new
tank.
8. lf the refrigerant tank has no float level sensor, please take the 80% O.F.P Cable off. Otherwise the
recovery unit can not started. In this case, an electric scale is required to monitor the recovered refrigerant
amount.
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 1,5 m.
10. While recovering large amounts of liquid, use the Push/Pull Mode.
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. lf 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.
16. After using , please turn the knob to "O"' position.
