INFICON shall have no liability in excess of the price paid to INFICON for the machine plus return transportation charges prepaid. INFICON shall have no liability for any incidental or consequential damages. All such liabilities are EXCLUDED.

3.0 Setup and Operation

3.1 Getting Started

Only personnel who have been properly trained in the use and operation of Refrigeration Systems, Refrigerants and Service Equipment should operate this equipment. Failure to follow proper safety precautions could result in personal injury or death.
Review the full contents of this Manual before attempting to use the Vortex in actual service.
Identify the refrigerant to be recovered and prepare the Vortex for use by installing an approved filter, hoses and optional shutoff cable per the diagram below.
Connect the AC Power cord to a circuit that is protected by a 15 amp breaker. Use an extension cord only when absolutely necessary to perform the service — be sure it is the minimum length required, that it contains a safety ground wire and that it contains wires sized 16 AWG or larger.

Vortex Operating Manual
Check all connections to ensure they are tight before starting the Recovery Operation.
When recovering refrigerant, it may be necessary to throttle the Manifold Gauge control valve(s) or the Vortex’s INLET Valve when a significant amount of liquid is present. This is required if a loud “knocking” sound is heard from the compressor. While the Compressor in the Vortex is tolerant of liquid, no compressor will run on 100% liquid without damage for more than a few minutes. In addition, a liquid “slug” can cause the High Pressure shutoff to activate, thus adding time to the process. It is thus important to open the valves slowly and monitor the process carefully. Should the compressor start to “Knock”, rotate the INLET valve clockwise until the “knocking” stops. This can also be accomplished by adjusting the Manifold Gauge valves. Exercise care to ensure that the compressor is not damaged in this way as it will void the warranty.
It is necessary to use a Refrigerant Scale to ensure that the tank is not filled to more than 80% of its capacity by weight. When operating in the NORMAL RECOVERY or PUSH-PULL mode, it is possible to overfill the tank. Check the tank weight before transporting if you are not sure. OVERFILLED TANKS CAN RUPTURE EXPLOSIVELY!

3.2 Normal Recovery Operation 1

Connect all cables and hoses as described in section 3.1 and as shown in Figure 3-1 below. Ensure that they are tight and routed in such a way that they will not interfere with the operation.
Figure 3-1 Setup Procedure For Normal Refrigerant Recovery

Vortex Operating Manual
2 Make sure that the hose from the Vortex to the Recovery Tank is
attached to the LIQUID PORT. Open the tank’s LIQUID PORT valve, keeping the VAPOR port closed.
3 CLOSE the INLET valve (V1). 4 OPEN the DISCHARGE valve (V3) to its fully open position. 5 SET the PURGE/RECOVERY valve (V2) to the RECOVERY position. 6 Open the Manifold Gauge LIQUID valve slowly and verify that no leaks
are present. Extracting as much liquid as possible will speed up the recovery process.
7 Switch ON the Vortex. 8 MONITOR the inlet pressure (LP, Low Pressure Gauge) and SLOWL Y
OPEN the Vortex’s INLET valve (V1). THROTTLE the INLET valve or the Manifold Gauge’s Liquid and Vapor valves if too much liquid is entering the machine.
9 When the liquid has been transferred, OPEN the INLET valve (V1) fully
to transfer the remaining VAPOR. Ensure that the Manifold Gauge valves (liquid and vapor) are also fully opened.
10 Continue to operate until the required VACUUM has been pulled on the
system, as indicated by the LP gauge. Switch OFF the Vortex, CLOSE the INLET (V1), and wait for 5 minutes. If the Pressure in the system, as noted on the Manifold Gauge, rises above 0 bar, refrigerant is still present. If this is the case, REOPEN the INLET (V1), RESTART the Vortex, and run until the required VA CUUM is reached again . Repeat this process until all the refrigerant is removed resulting in a fin al reading, after the 5 minute period, of 0 bar or less.
11 IMMEDIATELY PURGE the Vortex per the procedure as described in
section 3.3 of this Manual.

3.3 PURGING the Vortex

Rotate the PURGE/RECOVER valve (V2) to the PURGE position. Rotate
1
valve V3 to OPEN. See Figure 3-2.
2 Switch the POWER ON and rotate the INLET valve (V1) slowl y to the
PURGE. Prevent flooding the compressor with liquid, do not rotate the V1 valve quickly.
3 Observe the LP Gauge and continue to run the unit until a VACUUM of
at least -0.6 bar is achieved. Switch the POWER OFF and immediately CLOSE the Recovery Tank’s valve. The INLET valve (V1) should be returned to the CLOSE position. Finally close V3.

Vortex Operating Manual
4 IMPORTANT — RETURN V2 TO RECOVERY POSITION
THE HOSE AND THE DISCHARGE PORT WILL CONTAIN A SMALL AMOUNT OF REFRIGERANT UNDER PRESSURE. EXERCISE CARE WHEN REMOVING THIS HOSE AND OPENING THE VALVE V3.
Figure 3-2 Setup Procedure for Purging

3.4 Push-Pull Operation

The PUSH PULL method is used to move a large amount of liquid refrigerant from the system being serviced to the recovery tank without passing it through the compressor. This method is only useful when more than 7 kg of liquid is known to be in the system and it can be easily isolated. DO NOT ATTEMPT the PUSH PULL process unless you are sure of the situation.
Connect the refrigerant hoses as shown in Figure 3-3. The addition of a SIGHT GLASS in the line from the system being serviced to the recovery tank is an important aid to determine when the liquid has been transferred and vapor remains.
This process uses the PULL from the exhausted recovery tank and the Discharge PUSH from the Vortex to move the liquid refrigerant. Rates in excess of 7 kg per minute can be achieved by this procedure.
The SCALE is required in this process to ensure that the tank is not overfilled. The tank shutoff switch, if used, would stop the compressor but could not guarantee that additional refrigerant flow would cease because of the dynamics of the system, thus possibly overfilling the tank.

Figure 3-3 Setup Procedure for Push-Pull Method

3.5 Cooling The Recovery Tank

The Vortex can be used to PRE-cool (or SUB-cool) the recovery tank if the head pressure is too high to complete the recovery process. This can occur when working with certain refrigerants with a high vapor pressure when the ambient temperature is high.
If the recovery process stalls out because of high head pressure, stop the Vortex, shut off the hose valves and reconfigure the setup as shown in Figure
3-4. This can also be done before starting the recovery process, but it may
have marginal long term effect. NOTE: This will only work if there is at least 2 kg of liquid in the recovery
tank to develop the necessary pressure differential required.
8

Figure 3-4 Setup Procedure for Sub-Cooling Method
VAPOR
Optional Connection To System
POWER ON the Vortex and ROTATE the DISCHARGE V alve (V3) to achieve a pressure differential of at least 6.8 bar between the LP Gauge and the HP Gauge. KEEP THE HP BELOW 37.4 bar on the HP Gauge to ensure that the HP Cutoff Switch will not actuate.
After several minutes of running, the tank will be cold. POWER OFF the Vortex and reconfigure the setup for NORMAL RECOVERY. Repeat as needed.

3.6 Special Operating Notes

During normal operation, when the High Pressure switch activates the machine will restart automatically when the head pressure drops below approximately 28.9 bar.

4.0 Maintenance

4.1 Introduction

Your Vortex will provide many seasons of reliable service providing it is properly maintained. The actual maintenance requirements are minimal but important.
Keep the unit clean by wiping it down with a damp cloth to remove dirt, oils, etc., prior to storage for the day. Standard household detergent or isop ropyl alcohol may be used if the unit is particularly dirty — in all cases, exercise care to prevent liquids from entering the unit. Gasoline and other solvents are to be avoided as they can damage the Vortex’s plastic enclosure and they are hazardous.
Ensure that the Inlet and Discharge ports are protected in transit and storage — keep the inner diameter and the outer threads clear and clean. For best results, keep a FILTER permanently connected to the INLET port and change it regularly.
When performance falls off it is likely that the compressor seals require replacing. This is normal with use and may occur after a year or two, or more often depending upon the conditions that are prevalent during the recovery operations. Contact your Wholesaler for assistance in selecting the proper maintenance kit.
