THE SAFE WAY IS THE ONLY WAY!
NOTE! If you are not a qualified refrigerant service technician,
do not use this equipment
1. The technician should always wear goggles and gloves when working on
refrigeration systems.
2. Be sure that any room where you are working is thoroughly ventilated,
3. Always think before acting. Familiarity breeds carelessness and carelessnesscan
be harmful to your health or, worse, result in death.
4. Read the Material Safety Data Sheets (MSDS) on all compounds with which you
are likely to come in contact. Read MSDS on refrigerant and refrigerant oil. Obtain
MSDS sheets from your refrigerant supplier.
5. Never use oxygen when testing for leaks. Any oil in contact with oxygen under
pressure will form an explosive mixture.
6. Refrigerant systems are generally electrically driven and controlled. Be sure to
disconnect the unit from the power source before servicing it.
7. Always store refrigerant containers in a cool, dry place.
8. Always open service and cylinder valves slowly. This allows quick control of the flow
of gasses if there is any danger. Once it is determined that there is no danger, the
valves may be opened fully.
9. Do not mix refrigerant in a system, a tank or anywhere else. Each type of refrigerant
must have its own tank, filters, etc.
10. If moisture enters the refrigerant system, it is likely to cause considerable damage.
Keep everything connected with the refrigeration system thoroughly dry and clean.
11. To reduce the risk of fire, avoid the use of extension cords as they may overheat.If
you must use an extension cord iit should be a minimum of 14 AWG and not longer
than 25ft.
This equipment should be used in locations with mechanical ventilation providing at
least four air changes per hour, or the equipment should be located at least 45cm
(18”) above the floor. Do not use this equipment in the vicinity of spilled or open
containers of gasoline or any other flammable liquid.

RECOVERY & CONTAINMENT
Safety comes first. Read all safety information for the safe handling of refrigerant
including the Material Safety Data Sheet provided by your refrigerant supplier. Never
operate unit in an explosive environment. Wear safety glasses and protective gloves.
Work area must be well ventilated. This unit should only be operated by a qualified
technician.
*** CAUTION: REFRIGERANT STORE CONTAINERS ***
Use only approved cylinders with a minimum of 41 bar working pressure that serve the
current regulations.
NOTE: Recovery cylinders are designed for different pressures. Do not exceed the
working pressure of each cylinder.
Safety codes recommend that closed tanks not be filled over 80% of volume with liquid.
The remaining 20% is called head pressure room.
NEVER TRANSPORT AN OVERFILLED CYLINDER.
Refrigerant expands when it gets warm and may cause a tank to explode if overfilled.

IMPORTANT
GENERAL INFORMATION
Before operating the RG5410A-E recovery unit, read the following:
1. Always isolate large amounts of refrigerant and close off valves after use so if a
leak should develop anywhere in the system the refrigerant does not escape.
2. Storage cylinders sometimes have valves that are not properly seated when
manufactured. Keeping caps on these valves will guard against refrigerant leakage.
3. Always operate the unit on a flat level surface.
4. Your RG5410A-E has one internal pressure shut off switche. If the pressure inside
the system should go above 38,5 bar (550 psi), the system will automatically shut
itself off.
CAUTION
The 38,5 bar (550 psi) switch does not prevent tank overfill. If your system shuts
off on high pressure and is connected to your tank, you may have overfilled your
tank and created a very dangerous situation! Take immediate measures to relieve
any high pressure and/or tank overfill.
5. WARNING! Never overfill storage tanks. Overfilling may cause tanks to explode.
6. A scale must be used to avoid overfilling the storage tank.
7. Tanks and filters should be designated for one refrigerant only. Before using a tank
previously used for another refrigerant, completely empty the tank, evacuate it,
purge the tank using dry nitrogen, and re-evacuate it.
8. Special care should be taken when recovering from a burned-out system. Use two
high acid capacity filters, in series. Alco type EK-162-F or Sporlan type C-162-F are
recommended.
9. When you have finished recovering from the system, flush your RG5410A-E with a
small amount of refrigerant oil and a small amount of clean refrigerant to purge off
any foreign substances left in the unit.
10. Always empty refrigerant from the unit into a storage tank; see Self Purge/Auto
Evacuate procedure. Liquid refrigerant left in the condenser may expand, causing
damage to components.

OPERATING YOUR RG5410A-E
Procedure for Normal System Recovery
1. Inspect the RG5410A-E thoroughly to insure that it is in good operating condition.
2. Make sure all connections are correct and tight.
3. Open the liquid port of the recovery cylinder (always open valves slowly to check
hoses and connections for leaks).
4. Make sure the Recover/Purge valve is set on Recover.
5. Open the output port of the RG5410A-E.
6. Open the liquid port on the manifold gauge set; opening the liquid port will remove
the liquid from the system first, greatly reducing the recovery time (after the liquid
has been removed, open the manifold vapor port to finish evacuating the system).
7. Connect your RG5410A-E to a 230 V outlet.
a) Switch the main power switch to the ON position. You should hear the
fan running.
b) Press the compressor start switch. This "momentary" switch will start
the compressor (it may be necessary, under certain circumstances, to
press this switch more than once to start the compressor).
8. Slowly open the input port on the RG5410A-E.
a) If the compressor starts to knock, slowly throttle back the input valve
until the knocking stops.
b) If the input valve was throttled back, it should be fully opened once the
liquid has been removed from the system (the manifold vapor port
should also be opened at this time).
9. Run until minimum EPA required vacuum is achieved.
a) Close the manifold vapor and liquid ports.
b) Close the RG5410A-E input port.
c) Shut unit off and proceed with the Self Purge procedure on the next
page.
10. Always purge the RG5410A-E after each use. Failure to purge the remaining
refrigerant from the RG5410A-E could result in the acidic degradation of internal
components, ultimately causing premature failure of the unit.
CAUTION
When pumping liquid, do not allow the RG5410A-E to operate with the input valve
too far open, causing the compressor to knock. Doing so may stall the
compressor.

OPERATING YOUR RG5410A-E
Procedure for Purging Remaining Refrigerant From the RG5410A-E
1. Close the ports of the system being serviced that are connected to the input
port of the RG5410A-E.
2. Close the input port on the RG5410A-E.
3. Turn off RG5410A-E.
4. Turn the Recover/Purge valve to the purge position.
5. Restart the RG5410A-E.
6. Run until desired vacuum is achieved.
7. Close the ports on the recovery tank and the RG5410A-E.
8. Turn the RG5410A-E off.
9. Return the Recover/Purge valve to the recover position.
10. Disconnect and store all hoses.
11. Replace the in-line filter on your RG5410A-E after every time excessive
contaminant is encountered.
The use of the Low Pressure Switch
The RG5410A-E is equipped with a low pressure switch which is selectable ON/OFF
(VAC SENSOR SELECT). When the low pressure switch is switched ON the unit will
automatically switch off at 0,45 bar absolute. When the Low pressure Switch is
switched OFF the unit will continue to pump down the system even when the vacuum
stage has been reached.

RG5410A-E REFRIGERANT RECOVERY
ADDITIONAL INFORMATION
To achieve the deepest final vacuum, use the tank cooling method to lower the head
pressure on the recovery tank. Repeat as necessary to achieve the desired vacuum
level.
NOTE: If there is no liquid in the recovery tank, then the cooling method will not work. In
this case, use an empty tank that has been fully evacuated to achieve the final vacuum
level required.
To maximize recovery rates use the shortest possible length of 3/8” or larger hose. A
hose no longer than 3’0” is recommend. Always remove all unnecessary hose core
depressors and Schrader valves from port connections (using the proper valve core
tool) for maximum throughput. Deformed rubber seals and core depressors in hoses
and faulty or unnecessary Schrader valves can restrict flow by up to 90%.
If the tank pressure exceeds 31,5 bar, use the tank cooling procedure to reduce the
tank pressure. When recovering large amounts of liquid, use the “PUSH/PULL” method
of recovery (see diagram below).
CAUTION: When using the “PUSH/PULL” method, you must use a scale to prevent
overfilling the storage tank. Once the “PUSH/PULL” siphon is started, it can continue
and overfill the storage tank even if the tank is equipped with a float level sensor. The
siphon can continue even when the machine is turned off. You must manually close the
valves on the tank and the unit to prevent overfilling the recovery tank.

RG5410A-E RECOVERY
Purging the non-condensable gasses from identified refrigerant in a tank
1. Allow the tank to sit undisturbed for 24 hours. (This allows the air to rise to the top).
2. Connect a manifold to the tank and read the amount of pressure in the tank by
looking at the output pressure gauge.
3. Determine the ambient temperature in the room.
4. Refer to a Refrigerant pressure/temperature chart. Find the temperature on the
chart and look across to the corresponding pressure for the type of refrigerant in the
tank. Determine how that relates to the reading on the gauge.
5. If the pressure reading is higher than the pressure shown on the chart, very slowly
(so as not to cause turbulence inside the tank) crack open the vapor port valve.
Watch the pressure on the gauge decrease. To prevent venting, add 0,3 - 0,35 bar
(4 - 5 psi) to the pressure shown on the chart. When the gauge corresponds to that
pressure, close the vapor port valve.
6. Allow the tank to sit for 10 minutes and check the pressure again.
7. Repeat the process again if necessary.

.SAFETY PRESSURE SWITCH (WITH
MANUAL RESET FUNCTION)
The RG5410A-E is equipped with an internal Safety Pressure Switch. If the pressure
inside the system exceeds 38,5 bar, the system is switched off automatically.
If the Safety Pressure Switch is activated automatically whilst filling a bottle, it could be
caused by the bottle becoming overfilled.
This is a very dangerous situation! You should take steps immediately to reduce the
overpressure and/or to eliminate the overfilling of the bottle.
If the Safety Pressure Switch switches the unit off...
The following precautions should be taken if the Safety Pressure Switch is activated:
a) Suspected overfilling of the recovery bottle
Connect the recovery bottle to another bottle with spare capacity so that the pressure
is reduced to a safe level. This action should also reduce the pressure in the output line
from the RG5410A-E. Proceed as normal after resetting the Safety Pressure Switch
(see below).
b) Cause of activation of Safety Pressure Switch unknown
1) Check that the recovery bottle is not overfilled.
2) Close the system valves, recovery bottle valves and RG5410A-E valves.
3) Disconnect RG5410A-E from flexible pipes.
4) Disconnect RG5410A-E from the power supply.
5) Open the input and output valves very slowly.
6) Investigate the reason for the failure.
Once activated the Safety Pressure Switch has to be reset manually as follows:
I) Remove the black protection cover to reveal the reset button (see picture below).
II) Reset by pushing the reset button with a tool such as a screwdriver.
III) Replace the cover.
Remove this part in order to

CARE AND MAINTENANCE OF YOUR
RG5410A-E
A filter must always be used and should be replaced frequently. Failure to use a filter
will invalidate your warranty. The use of a filter will greatly reduce the risk of damage to
your RG5410A-E by preventing foreign material from entering the unit.
Special consideration for filtration must be given when you know the machine you are
servicing has "burned out". We recommend the use of two size 162 filter driers, in line,
to be used for that job and that job only. We also recommend that a clean filter be used
for every service job. Each filter should be labeled and used exclusively for one type of
refrigerant only.
Do not use this unit in the vicinity of spilled or open containers of gasoline or other
combustible liquids
Avoid the use of extension cords. If you must use an extension cord it should be a
minimum of 14 AWG and not longer than 25 ft. Not using an extension cord will greatly
reduce the risk of fire.
Always purge the unit of any refrigerant left after completing a service job. Refrigerant
left in the machine can expand and may cause damage to components.
If the unit is to be stored or not used for any length of time, we recommend that it be
completely evacuated of any residual refrigerant and purged with dry nitrogen.
Whenever you perform any type of maintenance work on your RG5410A-E, insure that
it is disconnected from the power supply before you begin.

HELPFUL HINTS FOR REFRIGERANT
RECOVERY
Refrigerant recovery has come a long way in a few short years.
On the surface it’s simply the process of taking refrigerant out of a system and putting it
into a tank. However, this simple process can quickly become problematic if a few items
are overlooked. The following are some tips and pointers we’ve accumulated over the
last few years that can save you time and make the process go smoother.
First you need to identify the refrigerant type and quantity in the system you are
servicing.
If you determine it’s a burnout, you need a special tank (a tank that’s identified as
containing burnout or other unidentified gases), and you need to use extra filtration prior
to recovery.
If, on the other hand, you know the gas in the system is relatively clean or new, then a
new tank should be used. If you’re planning on putting the refrigerant back into the
same system after you have finished the service or if the refrigerant is going to be
reclaimed, then use a tank that has the same refrigerant in it. A word of caution about
the Environmental Protection Agency (EPA): If you use a variety of refrigerant gasses in
your service work - as evidenced by your refrigerant purchases - and you only own one
tank, you are asking for trouble. You would be well advised to own at least one tank for
every refrigerant type serviced, plus an extra for burnouts and other unknowns.
Planning Ahead
Knowing the quantity of refrigerant is important for planning storage requirements, as
well as planning for the actual recovery. For instance, any system with more than 5lbs.
of refrigerant is likely to have areas where the liquid can get trapped.
The key to a quick recovery procedure is to get the liquid out first, and then get the
remaining vapor out. However most systems are not “recovery friendly.” That is they
don’t have access ports at their lowest points. If some units you’re servicing are on
maintenance contracts, you would save significant time by installing access ports at all
of the lowest points in the system, where liquid is likely to accumulate. Since most
systems don’t have these ports you need to be prepared to boil of the trapped liquid
with a heat gun, when ever it’s found. An indicator of trapped liquid in a system is frost
or condensation forming on the plumbing or components where the liquid is trapped.
The trapped liquid may be in an area that is not visible. In all cases trapped liquid in a
system during recovery causes the recovery process to slow down, regardless of the
size or type of machine
If you are unable to locate the trapped liquid (but you know it’s there, because the
recovery job is taking “forever”), turn on the system compressor (if it’s operable) for a
few seconds. This will get the refrigerant moving to another part of the system and in.

Advanced Test Products Europe RG5410A-E
- 18 -
HOSES AND VALVES
Hoses and Schraeder valves have a large impact on recovery speed. In general, the
larger the hose, the less friction on the flow of refrigerant, the quicker the recovery time.
Many contractors are now using 3/8” lines for the input to the recovery machine, even if
those lines originate out of 1/4” fittings.
Schraeder valves must be removed from the connection prior to an expedient
recovery. Most wholesalers sell a tool for removing these cores, while keeping the
connection sealed. The core depressor, in the end of the hose, should also be
removed. These two items can turn a 20 minute job into one that goes on for hours. So,
be sure to remove Schraeder valves and core depressors before every recovery job.
Another hose consideration is the little rubber grommet at the end of the hose that
makes a seal with the flare fitting. We’ve seen these seals so worm and deformed that
when the hose is connected to the flare fitting the grommet virtually seals off the the
connection. This is probably never noticed in charging, because the pressure opens the
grommet, but during recovery (or with suction) the deformed grommet severely restricts
the flow of refrigerant.
Refrigerant Recycling
Current regulations state that used refrigerant shall not be sold, or used in a different
owner’s equipment, unless the refrigerant has been laboratory analyzed and found to
meet the requirements of ARI 700 (latest edition). As a result, recycling and verifying
ARI 700 conformance isn’t economically justified in most cases. It’s still a great idea to
do as much cleaning of refrigerant going back into the same system (or owners
system) as possible. We recommend using the largest, high-acid capacity filter that are
economically feasIble. Put these filters on the suction or inlet side of the recovery unit.
Change filters often.
The recovery of large amounts of liquid refrigerant can sometimes carry with it large
quantities of oil, if the system being serviced doesn’t have an adequate oil separator
installed. If this recovered refrigerant isn’t going to be liquid charged back into the same
system, you might want to separate the refrigerant from the oil in order to
measure the oil (to know how much oil to charge back into the system). However
refrigerant sent back for reclaim does not need to have the oil removed. One of the
simplest and most cost effective ways to achieve this is to use a 30 or 50 lb. tank in line
with your recovery machine. Connect the the system to the liquid port of the tank then
from the vapor port of the tank connect to the input of your recovery machine a second
tank, for storing refrigerant, should then be connected to the output of the recovery
machine. If you encounter large amounts of liquid you will need to put a band heater
around the first tank.
When the recovery job is complete the oil can be removed, from the first tank, by
applying a small amount of pressure, using nitrogen, to one of the ports and
expressing the oil from the other. If you are going to remove the oil from the vapor port
you will need to turn the tank upside down. Always wear safety glasses when
performing this operation as the oil may be acidic and could cause severe burning.
