1.0 Safety Precautions
THIS EQUIPMENT MUST ALWAYS BE OPERATED BY A
QUALIFIED TECHNICIAN WHO IS FAMILIAR WITH REFRIGERANT
SYSTEMS, REFRIGERANTS, REFRIGERANT SAFETY AND LAWS
PERTAINING TO REFRIGERANT 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, eyeprotection and foot protection whenworking 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 and
install a separate circulation fan if necessary. DO NOT WORK IN AN
ENCLOSED AREA without special safety equipment as appropriate for
the 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™ or TEK-Mate®. NEVER USE OXYGEN for this process
as it can become an explosive mixture in the presence of oil and
pressure.
USE CAUTION WHEN OPERATING. This erquipment should be
used in clean, dry areas only. Be certain the power cord and the
equipment are not placed in residual water or other potentially
dangerous locations.
NEVER OVERFILL A STORAGE CONTAINER. The use of a
refrigerant scale, such as the INFICON Wey-TEK™, is required to prevent
overfill. OVERFILLED TANKS CAN RUPTURE EXPLOSIVELY!
OPEN SERVICE OR CYLINDERVALVES SLOWLY to ensure that all
connections are tight and there is no danger.

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,thusaddingtimeto theprocess. Itis thusimportanttoopenthe 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
1Connect 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
2Make 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.
3CLOSE the INLET valve (V1).
4OPEN the DISCHARGE valve (V3) to its fully open position.
5SET the PURGE/RECOVERY valve (V2) to the RECOVERY position.
6Open 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.
7Switch ON the Vortex.
8MONITOR the inlet pressure (LP, Low Pressure Gauge) and SLOWLY
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.
9When 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 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 per the procedure as described in
section 3.3 of this Manual.
3.3 PURGING the Vortex
1Rotate the PURGE/RECOVER valve (V2) to the PURGE position. Rotate
valve V3 to OPEN. See Figure 3-2.
2Switch the POWER ON and rotate the INLET valve (V1) slowly to the
PURGE. Prevent flooding the compressor with liquid, do not rotate the
V1 valve quickly.
3Observe 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
4IMPORTANT — 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.

Vortex Operating Manual
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.

9
Vortex Operating Manual
Figure 3-4 Setup Procedure for Sub-Cooling Method
POWER ON the Vortex and ROTATE the DISCHARGE Valve (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.
Afterseveral minutesofrunning, the tank will be cold. POWER OFF theVortex
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 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’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.
