WARNING : TO PREVENT PERSONAL INJURY AND / OR EQUIPMENT DAMAGE,
ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THIS UNIT. Before operating the unit,
read and follow the instructions and warnings in this manual. The operator must be familiar with air
conditioning and refrigeration systems, refrigerants, and the dangers of pressurized components. If
the operator cannot read this manual, operating instructions and safety precautions must be read and
discussed in the operator’s native language.
PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overll storage vessels, because
overfilling may cause explosion and personal injury or death. Do not recover refrigerants into
nonrellable containers; use only federally authorized rellable containers (DOT spec. 4BW or 4BA).
HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may
cause personal injury. Wear protective equipment, including safety goggles and protective gloves.
Disconnect hoses using extreme caution.
AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may
irritate eyes, nose, and throat. To remove refrigerant from the A/C systen, use only equipment certied
for the type of refrigerant being removed. Use the unit in locations with mechanical ventilation that
provides at least four air changes per hour. If accidental system discharge occurs, ventilate the work
area before resuming service.
TO REDUCE THE RISK OF FIRE, USE THE SHORTEST POSSIBLE EXTENSION CORD WITH A
MINIMUM SIZE OF 14 AWG. Using an undersized extension cord may result in electrical equipment
failure.
TO REDUCE THE RISK OF FIRE, do not use the unit in the vicinity of spilled or open containers of
gasoline or other ammable substances.
CAUTION – DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENT OR VEHICLE AIR
CONDITIONING SYSTEMS WITH COMPRESSED AIR. Some mixtures of air and refrigerant have
been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage.
DO NOT MIX REFRIGERANT TYPES THROUGH A SYSTEM OR IN THE SAME CONTAINER.
Mixing of refrigerants causes severe damage to the unit and the system being serviced.
HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure
may cause personal injury. Disconnect power before servicing the unit.
Additional health and safety information may be obtained from
refrigerant and lubricant manufacturers.
Explanationof SafEty Signal WordS
WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury.
CAUTION : Used without the safety alert symbol indicates a potentially hazardous situation which, if not
avoided, may result in property damage.
CAUTION : Filters prevent contamination from entering
the unit, which reduces the risk of damage to the unit
and the system being serviced.
The unit is shipped with a lter screen installed behind
the inlet tting. Robinair strongly recommends that a
clean lter screen be used for every service job. Failure
to use a lter screen will invalidate your warranty.
Robinair also strongly recommends using a lter / drier
(Part No. 100343; not provided) at the inlet tting. Each
in-line lter / drier must be labeled and used for only one
type of refrigerant.
Valves
WARNING : To prevent personal injury, open
service and cylinder valves SLOWLY to allow
rapid shut-off of gas flow if necessary. Once it is
determined there is no danger, the valves may be
opened fully.
Isolate large amounts of refrigerant and close valves
after use, so if a leak should develop anywhere in the
system, refrigerant will not escape to the atmosphere.
Storage Cylinders
WARNING : A storage cylinder is full when it
reaches 80% volume. DO NOT OVERFILL. Due to
liquid expansion, the cylinder could explode if filled
to more than 80% volume, possibly causing personal
injury and equipment damage. Use a scale, such
as the TIF9010A, to avoid overfilling the storage
cylinder.
Robinair recommends using the optional 80% Capacity
Shutoff Kit (p/n SK-5001) with this unit. After the kit is
installed and used with a recovery cylinder having an
internal oat switch, the unit automatically shuts down
when the cylinder is 80% full. (Your unit is pre-wired at
the factory for this kit.)
Hoses
Hoses must be equipped with low-loss ttings and have
pressure ratings appropriate for the refrigerant in the
system being serviced.
Shut-off Switch
This unit has an internal, high-pressure, shut-off switch.
If system pressure rises above 550 psi, the unit shuts
off. The shut-off switch automatically resets itself after
pressure drops below 400 psi.
WARNING : The internal pressure shut-off
switch does NOT prevent cylinder overfill. If the
system shuts off automatically and is connected
to a cylinder, the cylinder may be dangerously
overfilled. Take immediate measures to relieve the
high pressure and / or cylinder overfill situation, or
personal injury may result.
Push / Pull Procedure
When recovering large amounts of liquid (over 15 lbs.),
use the Push / Pull method described in this manual.
Maximum Vacuum and Recovery Rates
To achieve the deepest nal vacuum, use an evacuated
recovery cylinder. To maximize recovery rates :
Use the shortest possible length of 3/8 in. or larger
•
hose. (A hose no longer than 3 feet is recommended.)
Remove unnecessary hose core depressors, and
•
remove Schrader valves from port connections.
Deformed rubber seals and core depressors in hoses,
as well as faulty or unnecessary Schrader valves, can
restrict ow.
If you are certain the refrigerant in the system being
•
serviced is clean or new, the lter screen may be
removed from the inlet tting.
Purge the unit during the end of the vapor recovery
•
phase, especially when recovering large amounts
of vapor. Purge again after the recovery process is
complete and the desired vacuum has been achieved.

Tech Tips
The unit will perform at its peak when voltage
entering the machine (while operating) is between
115—122 VAC.
Lower supply voltages may result in difculty
starting under high head pressure, reduced
performance, and / or motor overheating.
Use an outlet that does not have other applicances
(such as lights, machines, etc.) plugged into it.
Do not use an extension cord unless needed. If
an extension cord is used, it must be 14 AWG
minimum and as short as possible to reduce
voltage drops.

Tech Tip
oPerating inStructionSfor bulk liquid SyStemS
“Push – Pull” Procedure
The push – pull method removes bulk liquid from a system using the pressure differential created by the unit.
This method works only with large systems where the liquid is readily accessible; it may not work on systems
that contain less than 15 lbs. (6.8 kg) bulk liquid.
This method is used :
• on systems with receiver cylinders.
• on systems containing more than 20 lbs. (9.1 kg) of refrigerant.
• when transferring bulk liquid refrigerant from one cylinder to another.

Purge non-condenSable gaSfroma Storage cylinder
1. Allow the storage cylinder to sit undisturbed for
24 hours to allow air to rise to the top.
2. Connect a manifold gauge set to the cylinder.
Read the amount of pressure in the cylinder as
indicated by the output pressure gauge.
3. Determine the ambient temperature in the
room.
4. Refer to a refrigerant pressure/temperature
chart and nd the ambient temperature. Read
across the chart to the corresponding pressure
for the type of refrigerant in the cylinder.
Determine how that relates to the reading on
the gauge.
5. If the pressure reading in the cylinder is
higher than the pressure shown on the chart,
VERY SLOWLY crack open the vapor port
valve. (This is done slowly to cause as little
turbulence inside the cylinder as possible.)
Watch the pressure on the gauge decrease. To
prevent venting, add 4–5 psi (0.26—0.34 bar)
to the pressure shown on the chart.When the
gauge corresponds to that pressure, close the
vapor port valve.
6. Allow the cylinder to sit for 10 minutes and then
check pressure again.
7. Repeat the process, if necessary.

recovery cylinder information
Type of Cylinder
Use only authorized, rellable, refrigerant storage
cylinders. Federal regulations require refrigerant
to be transported only in containers meeting DOT
specs. 4BW or 4BA.
NEVER use a standard disposable 30 lb.
(13.6 kg) cylinder (the type of container in which
new refrigerant is sold) to recover refrigerant.
Working Pressure
Recovery cylinders are designed for different
working pressures. Robinair strongly recommends
the use of 400 psi (27.6 bar) cylinders.
WARNING: To prevent personal injury, do
not exceed the rated working pressure of the
cylinder. At minimum, the RG6 requires the use
of a 350 psi (24.1 bar) recovery cylinder.
NOTE: The use of a 400 psi (27.6 bar) cylinder is
mandatory when recovering R-410A refrigerant.
Refer to the Parts and Accessories section of this
manual for more information.
If you expect temperatures in excess of 135º F
(57° C), consult the refrigerant supplier.
Capacity
Safety codes state that closed cylinders should
not be lled with liquid over 80% of volume. (The
remaining 20% is called head pressure room.)
Do not exceed 80% of cylinder capacity. Robinair
recommends the use of the TIF9010A Refrigerant
Scale for monitoring cylinder capacity.
Refrigerants
Cylinders and lter / driers should each be
designated for only one type of refrigerant.
If you must use a cylinder previously used for
a different refrigerant, prepare the cylinder by
completely emptying it, perform an evacuation,
purge it using dry nitrogen, and then perform
another evacuation.
Storage
Store refrigerant cylinders in a cool, dry place.
Leakage
Some cylinders have valves that were not correctly
seated when manufactured. Keeping caps on the
valves will guard against refrigerant leakage.
WARNING : To prevent personal injury, never transport an overfilled cylinder.
Refrigerant expands when it gets warm and may cause an overfilled cylinder to explode.

um die besten Resultate beim Absaugen zu erzielen.
Kältemittel
Identizieren Sie den Typ und die Menge des Kältemittels
im jeweiligen System.
Das Gerät RG6 ist zugelassen für die Verwendung mit
den folgenden Kältemitteln der Kategorie III, IV und V
für jeden neuen Serviceauftrag ein sauberes Filtersieb
zu verwenden. Wenn Sie das Gerät ohne Filter betreiben,
wird die Garantie ungültig.
Robinair empehlt ebenfalls unbedingt die Verwendung
eines Filter/Trockners (Teile-Nr. 100343, nicht mitgeliefert)
am Einlassanschluss. Jeder Leitungslter mit Trockner
muss gekennzeichnet werden und darf nur für einen
Kältemitteltyp verwendet werden.
Ventile
WARNUNG: Um Verletzungen zu vermeiden,
öffnen Sie Ablass- und Flaschenventile nur LANGSAM,
damit Sie den Gasstrom nach Bedarf schnell sperren
können. Sobald Sie festgestellt haben, dass keine
Gefahr vorliegt, können die Ventile vollständig
geöffnet werden.
Isolieren Sie große Mengen Kältemittel und schließen
Sie die Ventile nach der Verwendung, damit kein
Kältemittel in die Atmosphäre austritt, falls eine
Undichtigkeit im System entsteht.
Kältemittelaschen
WARNUNG: Eine Kältemittelflasche ist bei einer
Füllmenge von 80 % vollständig gefüllt. NICHT
ÜBERFÜLLEN. Aufgrund der Ausdehnung von
Flüssigkeit kann die Flasche explodieren, wenn sie
zu mehr als 80 % gefüllt wird und Verletzungen und
Sachschäden verursachen. Verwenden Sie eine
Waage, wie die TIF9010A, um ein Überfüllen der
Kältemittelflasche zu vermeiden.
Robinair empehlt die Verwendung des optionalen
Abschaltkits bei 80 % Füllmenge (Teile-Nr. SK-5001) mit
diesem Gerät. Wenn das Kit eingebaut wurde und mit
einer Kältemittelasche mit internem Schwimmerschalter
verwendet wird, schaltet sich das Gerät automatisch ab,
wenn die Flasche zu 80 % gefüllt ist. (Ihr Gerät wurde
werksseitig für dieses Kit vorverdrahtet.)
Schläuche
Schläuche müssen mit verlustarmen Armaturen
ausgestattet sein und einen Nenndruck aufweisen, der
für das im System enthaltene Kältemittel angemessen ist.
Überdruckschalter
Das Gerät ist mit einem internen Überdruckschalter
ausgestattet. Wenn der Systemdruck über 37,9 Bar
(550 psi) ansteigt, schaltet sich das Gerät aus. Der
Überdruckschalter wird automatisch zurückgesetzt,
wenn der Druck unter 27,6 Bar (400 psi) fällt.
WARNUNG: Der interne Überdruckschalter
verhindert NICHT das Überfüllen der Flasche.
Wenn sich das System automatisch abschaltet
und noch an eine Flasche angeschlossen ist, kann
diese Flasche auf ein gefährliches Niveau überfüllt
werden. Entlasten Sie umgehend den Druck in
der Flasche, indem Sie die Flasche entsprechend
entleeren, um Verletzungen zu vermeiden.
Druck-Zugmethode („Push-Pull“)
Beim Absaugen großer Mengen Flüssigkeit
(über 6,8 kg [15 lb.]), gehen Sie nach der in dieser
Sie eine evakuierte Kältemittelasche. So erzielen Sie
optimale Absaugraten:
• Der verwendete Schlauch muss so kurz wie möglich
sein und einen Durchmesser von mindestens 0,95 cm
(3/8 Zoll) aufweisen. (Wie empfehlen die Verwendung
eines Schlauchs von max. 90 cm [3 Fuß] Länge.)
• Lösen Sie unnötige Ventilkerndrücker und
Schraderventile von den Anschlüssen. Deformierte
Gummidichtungen und Ventilkerndrücker in Schläuchen
sowie defekte oder unnötige Schrader-Ventile können
den Druck drosseln.
• Wenn Sie sicher sind, dass das Kältemittel im System
sauber oder neu ist, kann das Filtersieb aus dem
Einlassanschluss entfernt werden.
• Entleeren Sie das Gerät RG6 am Ende der
Dampfabsaugphase, besonders beim Absaugen
großer Dampfmengen. Entleeren Sie es erneut
nach dem Absaugverfahren, wenn das gewünschte
Vakuum erzielt wurde. Siehe hierzu „Entleeren des
