INTRODUCTION Congratulations on your purchase of the ProVax™ refrigeration recovery/evacuation system. Using an innovative new design (patents pending), Promax™ has created a unique recovery system. The ProVax™ combines both a recovery unit and a vacuum pump into one unit, conveniently eliminating the need to carry both to the job site.
m IMPORTANT SAFETY & OPERATING GUIDLINE INFORMATION m PERSONAL SAFETY TANK SIZE 30 lb. Tank 50 lb. Tank mSAFETY COMES FIRST! Read all safety, operating guidelines and instructions before operating your ProVaxTM. MAX NET WEIGHT 24 lbs. 40 lbs. TABLE 1: Representative Sample, R-22 CAUTION: ONLY A QUALIFIED TECHNICIAN SHOULD OPERATE THIS RECOVERY UNIT. The operator must be familiar with air conditioning and refrigeration systems, refrigerants and the dangers of pressurized components.
m IMPORTANT SAFETY & OPERATING GUIDLINE INFORMATION m ELECTRICAL SAFETY CONT- Always open service and cylinder valves slowly. This allows rapid control of the flow of gases if there is any danger. Once it is determined that there is no danger, the valves can be opened fully. When using an extension cord it should be a 3-wire, 14 AWG minimum and no longer than 25 feet.
CARE AND MAINTENANCE OF YOUR ProVaxTM Use of a filter/dryer at the inlet is mandatory. A filter/dryer must always be used between the recovery machine and the inlet hose.We recommend that a clean filter be used for every service job. Failure to use a filter will invalidate your warranty. Do not expose Vacuum Pump to pressure. It is protected by a pressure cut-off switch set at 25 psi (+/- 5). Maximum vacuum level 13 in. Hg while in Recovery mode.
ADDITIONAL RECOVERY TANK INFORMATION m WARNING: Also read the information pertaining to recovery tanks, previously listed under Safety Information and Operating Guidelines. 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 and purge the tank using dry nitrogen, and then re-evacuate it. m CAUTION: NEVER use a standard disposable 30 lb.
PURGING NON-CONDENSABLE GASES FROM REFRIGERANT TANK 1. Allow the tank to sit undisturbed for 24 hours. This allows the air to rise to the top. 2. Connect a manifold to the tank and read the amount of pressure in the tank by looking at the output pressure gauge. 3. Determine the ambient temperature in the room. 4. Refer to a Refrigerant pressure/temperature chart. Find the temperature on the chart and look across to the corresponding pressure for the type of refrigerant in the tank.
HELPFUL HINTS FOR REFRIGERANT RECOVERY Refrigerant recovery has come a long way in a few short years. On the surface it's simply the process of taking refrigerant out of a system and putting it into a tank. However, this simple process can quickly become problematic if a few items are overlooked. The following are some tips and pointers we've accumulated over the last few years that can save you time and make the process go smoother.
HELPFUL HINTS FOR REFRIGERANT RECOVERY - cont. This is probably never noticed in charging, because the pressure opens the grommet, but during recovery (or with suction) the deformed grommet severely restricts the flow of refrigerant. KEEPING THE DIRT OUT During the recovery process your recovery machine can be exposed to debris that can, potentially, damage it. This includes brazing spatter and copper/ brass slithers. Further contamination can be introduced from the refrigerant storage tanks.

OPERATING YOUR ProVaxTM PROCEDURE FOR NORMAL SYSTEM RECOVERY 1. Inspect the ProVax thoroughly to insure that it is in good operating condition. 10. Open the output valve/knob (RED) on the ProVax. 2. Ensure that the outlet valve/knob (RED) and the inlet valve/knob (BLUE) on the ProVax are in the closed positions. 11. Slowly open the input valve/knob (BLUE) on the ProVax. a. If the compressor starts to knock, slowly throttle back the input valve/knob until the knocking stops. b.
OPERATING YOUR Provax - cont. PROCEDURE FOR SELF PURGE 8. Close the recovery tank valves and close the Outlet valve/knob (RED) and Inlet valve/knob (BLUE) on the ProVax. 9. Turn the ProVax “Power” switch "Off". 10. Return the Recover/Purge valve/knob (BLACK) knob to the "Recover" position. 11. Turn the Inlet valve/knob (BLUE) to the "Closed" position. 12. Disconnect and store all hoses. 1. Ensure the "MODE" valve/knob (YELLOW) is in the "Recovery" position. 2.
DIAGRAM FOR “PUSH/PULL” METHOD Push/pull method only works with large systems where the liquid is readily accessible. Do not use this method on systems that contain less than 6.8 kg (15 lbs.) as it may not work. The sight glass is used to provide a method of determining the moisture content and quality of a system’s refrigerant. m CAUTION: When using the “Push/Pull” method, once the siphon is started, it can continue and overfill the storage tank even if the tank is equipped with a float level sensor.
OPTIONAL RECOVERY/TANK PRE OR SUB COOLING FOR FIXED HOSE SET-UP MANIFOLD GAUGE SET INPUT SYSTEM BEING SERVICED LIQUID VAPOR LIQUID OUTPUT m WARNING! A scale must be used to avoid over filling the storage tank. NORMAL RECOVERY: Tank Vapor valve is closed TANK PRE OR SUB COOLING: Tank Vapor valve is open and both manifold gauge set valves are closed.
VACUUM PUMP MAINTENANCE Vacuum Pump Oil For maximum performance, Promax recommends changing vacuum pump oil after each use. The condition and type of oil used in any high vacuum pump are extremely important in determining the ultimate attainable vacuum. Promax recommends the use of Robinairs Premium High Vacuum Pump Oil. This oil has been specifically blended to maintain maximum viscosity at normal running temperatures and to improve cold weather starts.
