GENERAL SAFETY GUIDELINES
1. Read all safety, operating guidelines and instructions before operating
this unit.
2. Only a qualified technician should operate this Recovery unit!
3. Always wear safety goggles and protective gloves when working with
refrigerants to protect your skins and eyes from refrigerant gases and
refrigerant liquid. Avoid getting in touch with causticity liquid or gas.
4. Do not expose the equipment in the sun or rain.
5. Be sure that any room where you are working is thoroughly ventilated.
6. Use ONLY authorized refillable refrigerant tanks. It requires the use of
recovering tanks with a minimum of 27.6bar working pressure.
7. Do not overfill the stor age tank. Tank is full at 80% volume. There should
be enough space for liquid expansion
overfilling of the tank may cause
a violent explosion. A scale must be used to avoid over filling the storage
tank .
8. Do not exceed the working pressure of Recovering Tank cylinder.
9. Do not mix different refrigerants together in one tank, or they could not
be separated or used.
10. Before recovering the refrigerant, the tank should achieve the vacuum
level: -0.1mpa, 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.
11. When the unit 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 unit.
12. When using an extension cord it should be a 14AWG minimum and no
longer than 7.6meters, or it may make the voltage drop and damage the
compressor.
13. 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 specified by our
company. High quality dry filters will bring high quality services.
14. Special care should be taken when recovering from a burned-out
system. Use two high acid capacity filters, in series. When you have
finished recovering from the system, flush the unit with a small amount
of clean refrigerant and refrigerant oil to purge off any foreign substances
left in the unit.
15. This unit has an Internal Pressure Shut Off Switch. If the pressure inside
the system should go above 38.5bars, the system will automaticall y shut
itself off. The shut off switch must be manually reset. (Access to the
Shut -Off switch is through the hole located in the lowe r left fron t panel.
16. If the tank pressure exceeds 20.7bar, use the Storage Tank Cooling
Method to reduce the tank pressure.
17. To maximize recovery rates, use the shortest possible length of 3/8
or larger hose. A hose no longer than 0.9meter is recommended.
18. When recovering large amounts of liquid, use the Liquid Push/Pull
method .
19. After recovering, make sure there's no refrigerant left in the unit. Read
the Self -Purging Method carefully. Liquid refrigerant remained may
be expanded and destroy the components.
20. 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.

LIQUID PUSH/PULL METHOD
Push/pull method only works with large systems where the liquid refrigerant
is no less than 10kg.
CAUTION: When using the Push/pull method, a scale must be used
to avoid over filling the storage tank, once the siphon is
started, it can continue and overfill the storage tank even if
the tank is equipped with a float level sensor. The siphon
can continue even when the machine is turned off. You must
manually close the valves on the tank and the unit to prevent
overfilling of the recovery tank.
1. Put Recover/Purge knob on Recover.
2. Open Output valve.
3. Open Input valve.
4. When the scale stops rising close all ports.
5. Switch off the machine.

THE STORAGE COOLING METHOD
Pre-work Cooling Procedure
1. To start you must have a minimum of 0.5kg of liquid refrigerant in the
tank.
2. Turn the Recover/Purge valve to the Recover position.
3. Open the Vapor and Liquid valve of the storage tank.
4. Power on, and start the compressor.
5. Open the Input valve and Output valve of the unit.
6. Throttle the Output valve of the unit so that the output pressure is 100psi
greater than the input pressure, but never more than 300psi.
7. Run until tank is cold.
