1.0 Safety Precautions
THIS EQUIPMENT MUST ALWAYS BE OPERATED BY A QUALIFIEDTECHNICIAN WHO IS FAMILIAR WITH REFRIGERANT SYSTEMS,REFRIGERANTS, REFRIGERANT SAFETY AND LAWS PERTAINING TOREFRIGERANT USEAGE.
READ THIS MANUAL and become familiar with the specifications
and operation of this machine prior to use.
WEAR APPROPRIATE SAFETY PROTECTION APPAREL such as
gloves, eye protection and foot protection when working on refrigeration
systems.
REFRIGERANT VAPOR CAN BE HAZARDOUS AND ITS BY
PRODUCTS CAN BE LETHAL — work only in well ventilated areas. When
working indoors, ensure there is adequate airflow in the work space andinstall a separate circulation fan if necessary. DO NOT WORK IN AN
ENCLOSED AREA without special safety equipment as appropriate forthe conditions.
KNOW THE PROPER SAFETY AND HANDLING REQUIREMENTS
for the Refrigerant being recovered by reviewing the Material Safety Data
Sheets (MSDS) and the Temperature - Vapor Pressure information.
PERFORM LEAK DETECTION in accordance with recommended
practice only. For best results use only a refrigerant detector such as the
INFICON D-TEK™ Select, Compass™ or TEK-Mate®. NEVER USE
OXYGEN for this process as it can become an explosive mixture in thepresence of oil and pressure.
USE CAUTION WHEN OPERATING. This equipment should be
used in clean, dry areas only. Be certain the power cord and theequipment are not placed in residual water or other potentially
dangerous locations.
NEVER OVERFILL A STORAGE CONTAINER. The use of arefrigerant scale, such as the INFICON Wey-TEK™, is required to prevent
overfill. OVERFILLED TANKS CAN RUPTURE EXPLOSIVELY!

Vortex AC Operating Manual

3.0 Setup and Operation
3.1 Getting Started
Only personnel who have been properly trained in the use andoperation 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 AC in actual service.
Install an approved filter on the inlet. Attach the hoses per the diagram below.
The Vortex AC has a female refrigerant flare fitting so that it may accept a filter
with male flare fittings, the hoses then attach to the filter. DO NOT USE AN
ADAPTER FITTING IN PLACE OF A FILTER AS THIS MAY CAUSEDAMAGE TO THE VALVES AND VOID THE WARRANTY.
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 groundwire and that it contains wires sized 16 AWG or larger.
When recovering refrigerant, it may be necessary to throttle the Manifold
Gauge control valve(s) or the Vortex AC’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 AC is tolerant ofliquid, 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 toactivate, 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 canalso be accomplished by adjusting the Manifold Gauge valves. Exercise careto ensure that the compressor is not damaged in this way as it will void thewarranty.
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!

Vortex AC Operating Manual

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

2

Make sure that the hose from the Vortex AC 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).

4OPEN 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 therecovery process.

7

Switch ON the Vortex AC.

8

MONITOR the inlet pressure (LP, Low Pressure Gauge) and SLOWLYOPEN the Vortex AC’s INLET valve (V1). THROTTLE the INLET valve
or the Manifold Gauge’s Liquid and Vapor valves if too much liquid isentering 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.

6

Vortex AC Operating Manual

10 Continue to operate until the required VACUUM has been pulled on thesystem, as indicated by the LP gauge. Switch OFF the Vortex AC,
CLOSE the INLET (V1), and wait for 5 minutes. If the Pressure in thesystem, 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 AC, and run until the required VACUUM is reached again.
Repeat this process until all the refrigerant is removed resulting in a
final reading, after the 5 minute period, of 0 bar or less.

11 IMMEDIATELY PURGE the Vortex AC per the procedure as describedin section 3.3 of this Manual.

3.3 PURGING the Vortex AC
1Rotate the PURGE/RECOVER valve (V2) to the PURGE position. Rotate
valve V3 to OPEN. See Figure 3-2.

2

Switch the POWER ON and rotate the INLET valve (V1) slowly to the
PURGE. Prevent flooding the compressor with liquid, do not rotate theV1 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.

4

IMPORTANT — RETURN V2 TO RECOVERY POSITION

THE HOSE AND THE DISCHARGE PORT WILL CONTAIN A SMALLAMOUNT OF REFRIGERANT UNDER PRESSURE. EXERCISE CARE
WHEN REMOVING THIS HOSE AND OPENING THE VALVE V3.
Figure 3-2 Setup Procedure for Purging

7

Vortex AC Operating Manual

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 throughthe 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 tankis an important aid to determine when the liquid has been transferred andvapor remains.
This process uses the PULL from the exhausted recovery tank and theDischarge PUSH from the Vortex AC to move the liquid refrigerant. Rates inexcess 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 notguarantee 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 AC can be used to PRE-cool (or SUB-cool) the recovery tank if thehead pressure is too high to complete the recovery process. This can occur
when working with certain refrigerants with a high vapor pressure when theambient temperature is high.

8Vortex AC Operating Manual
If the recovery process stalls out because of high head pressure, stop the
Vortex AC, 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.

Figure 3-4 Setup Procedure for Sub-Cooling Method

VAPOR

Optional Connection To System

POWER ON the Vortex AC and ROTATE the DISCHARGE Valve (V3) toachieve a pressure differential of at least 6.8 bar between the LP Gauge andthe HP Gauge. KEEP THE HP BELOW 37.4 bar on the HP Gauge to ensurethat the HP Cutoff Switch will not actuate.
After several minutes of running, the tank will be cold. POWER OFF the Vortex
AC and reconfigure the setup for NORMAL RECOVERY. Repeat as needed.

9Vortex AC Operating Manual

3.6 Special Operating Notes
During normal operation, when the High Pressure switch activates themachine will restart automatically when the head pressure drops below
approximately 28.9 bar.

4.0 MaintenanceYour Vortex AC will provide many seasons of reliable service providing it isproperly 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 isopropyl
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 AC’s plastic enclosure and they arehazardous.
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 andchange 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.
