1.Read all safety, operating guidelines and instructions before opera ting this recovery machine.
2. Always think before acting, familiarity breeds carelessness, and carelessness can be harmful to your health, or worse, result
in death.
3.Only a qualified technician should operate this Recovery machine.
4.Read all safety information regarding the safe handling of refrigerant and refrigerant oil, including the Material Safety Data
Sheet. MSDS sheets can be obtained from your refrigerant supplier.
5. Always wear safety goggles and protective gloves when working with refrigerants to protect your skins and eyes from
refrigerant gase s and refrigerant liquid. Avoid getting in touch with causticity liquid or gas.
6. Be sure that any room where you are working is thoroughly ventilated.
7.Use ONLY authorized refill able refrigerant tanks. It requires the use of recovering tanks with a minimum of 27.6bar working
pressure.
8.Do not overfill the storage tank. Tank is full at 80% volume. There should be enough space for liquid expansion---overfilling
of the tank may cause a violent explosion.
9.Do not exceed the working pressure of Recovering Tank cylinder.
10.Do not mix different refrigerants together in one tank, or they could not be separated or used.
11.Before recovering the refrigerant, the tank should achieve the vacuum level: -0.1mpa, which is for purging non-conden-
sable gases. Each tank was full of nitrogen when it was manufactured in the fac tory, thus the nitrogen should be evacuated
before the first use.
12.When the recovery machine is not used, all the valves should be closed. Because the air or the moisture of the air may harm
the recovery result and shorten the service life of the recovery machine.
13.When using an extension cord, it should be a 14AWG minimum and no longer than 7.62 meters (25feet), or it may make
the voltage drop and damage the compressor.
14.A dry filter must always be used and should replaced frequently. And each type of refrigerant must have its own filter. For
the sake of assuring the normal operation of the unit, please use the filter spe cified by our company. High quality dry filters
will bring high quality services.
15. Special care should be taken when recovering from a burned-out system. Use two high acid capacity filters, in s erie s.
When yo u have finished recovering from the system, flush the recovery machine with a small amount of clean refrigerant
and refrigerant oil to purge off any foreign substances left in the machine.
16. This recovery machine has a Pressure Shut Off Switch. If the pressure insi de the system should go above 38bars, the system
will automatically shut itself off. The shut off switch must be manually reset.
17. If the tank pressure exceeds 20.7bar, use the TANK COOLING PROCEDURE to reduce the tank pressure.
18. To maximiz e recovery rates, use the shortest possible length of 3/ 8 or larger hose. A hose no longer than 0.9meter is
recommended.
19. When recoveri ng large amounts of liquid, use the LIQUID PUSH /PULL PROCEDURE.
20. After recovering, make sure there’s no refrigerant left in the machine. Read the SELF -PURGING PROCEDURE carefully.
Liquid refrigerant remained may be expanded and destroy the components.
21. If this recovery machine 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.
22.To reduce the risk of injury, care should be taken when moving this machine.
