IMPORTANT
GENERAL INFORMATION
Before operating the RG5410A-EXTREME recovery unit, read the following:
1. Always isolate large amounts of refrigerant and close off valves after use so if a leak
should develop anywhere in the system the refrigerant does not escape.
2. Storage cylinders sometimes have valves that are not properly seated when
manufactured. Keeping caps on these valves will guard against refrigerant leakage.
3. Always operate the unit on a flat level surface.
4. Your RG5410A-EXTREME has one internal high-pressure shut-off switch. If the
pressure inside the system should go above 38,5 bar (550 psi), the system will
automatically shut itself off.
CAUTION
The 38,5 bar (550 psi) switch does not prevent tank overfill. If your system shuts
off on high pressure and is connected to your tank, you may have overfilled your
tank and created a very dangerous situation! Take immediate measures to relieve
any high pressure and/or tank overfill.
5.
WARNING! Never overfill storage tanks. Overfilling may cause tanks to explode.
6. A scale must be used to avoid overfilling the storage tank.
7. Tanks and filters should be designated for one refrigerant only. Before using a tank
previously used for another refrigerant, completely empty the tank, evacuate it,
purge the tank using dry nitrogen, and re-evacuate it.
8. Special care should be taken when recovering from a burned-out system. Use two
high acid capacity filters, in series. Alco type EK-162-F or Sporlan type C-162-F are
recommended.
9. When you have finished recovering from the system, flush your RG5410A-
EXTREME with a small amount of refrigerant oil and a small amount of clean
refrigerant to purge off any foreign substances left in the unit.
10. Always empty refrigerant from the unit into a storage tank; see Self Purge/Auto
Evacuate procedure. Liquid refrigerant left in the condenser may expand, causing
damage to components.
