Page 5: Product Description
General Information Product Description RefTec’s AllVac recovery system provides automated recovery of most low & high pressure refrigerants and blends. The unit consists of a 3 or 5-hp compressor with oil separator, disposable liquid & vapor prefilter driers, high capacity air cooled condenser, microprocessor control system, and actuated valving system.

Page 9: Operating Procedures
Operation Operating Procedures To ensure your safety as well as others, before attempting to recover an A/C, refrigeration or chiller system, proper and thorough preparation must take place: • Make sure you have a recovery cylinder with a minimum 3/4” male flare vapor port and a minimum 3/4”...
Page 10 Operation An additional feature can be accessed at this time, by pressing the “M” key. This display will show you total compressor run time as well as give you a historical maintenance schedule. In addition, at every 10 hours of cumulative operating run time for the compressor, an automatic message will appear each time you start the AllVac until maintenance is performed.
Page 11 Operation Note 1: If recovery tank side hoses have isolation valves, open them now. 13.“To Evacuate Hoses Press Enter, To Skip Hose Evacuation Press Cancel” if “Enter” is pressed, unit displays “Hose Evacuation in Pro- cess” followed by “Hose Evacuation Complete, Press Enter”. 14.Next “Open Vapor &...
Page 12 Operation Upon pressing “Enter”, AllVac prompts you to perform the following valve manipulations 20-26: Note 3: Close additional liquid access valve at this time, if being used. 20.“Close Access Valves on A/C System Being Recovered” then press”Enter”. 21.“Close Both Hand Valves on AllVac Unit A/C System Side” press “Enter”.
Page 13 Operation Note 4: If additional liquid line is connected for faster liquid recovery, open chiller and recovery tank valves now. When AllVac goes into vapor recovery, close recovery tank side of the hose. 33.AllVac will remain in liquid transfer state until manually switched to vapor transfer as follows: Once all liquid from chiller has been transferred and absolutely no liquid refrigerant is remaining in clear recovery hoses and you are absolutely...
Page 14: Removing Residual Refrigerant
Operation At this point, the microprocessor continues to monitor chiller pressure. Should pressure rise, AllVac restarts to again achieve the user-selected vacuum. 35.Then the display will read “Chiller Vapor Recovery Finished! press Enter”. Upon pressing “Enter”, AllVac prompts you to perform the following valve manipulations 36 - 42: Note 5: Close additional liquid access valve at this time, if being used.
Page 15 Operation Changing Replaceable Cores Make sure you replace filter cores after each recovery job. Simply unscrew used filter assembly and replace. Procedures for Recharging System Using AllVac These procedures provide for the transfer of refrigerant liquid and vapor from a recovery tank to a centrifugal chiller system using the AllVac recovery unit. These procedures are to be used when clean refrigerant is being returned to a chiller without recycling.
Page 16 Operation 2. Evacuate Air from Chiller, AllVac and Hoses. a) Once all lines are connected, open the AllVac valves in the following se- quence: system liquid, system vapor, tank liquid, and tank vapor on AllVac only. b) Connect manifold gauge set and vacuum pump to ports on side of AllVac unit at compressor suction and discharge ports.
Page 17 Operation b) Before proceeding with this procedure, chiller pressure must be at a mini- mum of 15” Hg. of vacuum or greater for R-11 or R-123. The minimum pressure for R113 is 25” Hg. vacuum. If the chiller is not above the mini- mum level, do not proceed with liquid transfer, but repeat procedure 3 above.
Page 18 Operation 5. Evacuating Refrigerant Vapor From Recovery Tank and Hoses (This step removes any liquid or refrigerant vapor in the recovery tank and connecting hoses.) a) Energize chiller condenser and evaporator water pumps. Water should be flowing through both evaporator and condenser during this procedure to reduce the potential for freezing chiller tubes.
Page 19: Calibration
Calibration Procedure Steps: 1. At power up, the AllVac Recovery Unit will display: “AllVac COMMERCIAL RECOVERY UNIT” “HAS POWER (PRESS START)“ 2. At this screen you must press “CANCEL” twice within 5 seconds to enter the CALIBRATION mode.
Page 20: Changing Compressor Fluid
If you press “CANCEL”, a new calibration factor will not be calculated. It will then display the following message and be ready for operation: “ALLVAC COMMERCIAL RECOVERY UNIT” “HAS POWER (PRESS START) “ Changing Compressor Fluid The compressor’s charge of Poly Ester fluid should be regularly replaced...
