m IMPORTANT SAFETY INFORMATION m
SAFETY COMES FIRST! Read all safety, operating
guidelines and instructions before operating your
RG5410A.
1. CAUTION: ONLY A QUALIFIED TECHNICIAN
SHOULD OPERATE THIS RECOVERY UNIT.
The operator must be familiar with air conditioning
and refrigeration systems, refrigerants and the
dangers of pressurized components.
2. Always think before acting, familiarity breeds care-
lessness and carelessness can be harmful to your
health or, worse, result in death.
3. m WARNING Always wear safety goggles and
protective gloves when working with refrigerants.
Contact with refrigerant may cause injury.
Disconnect hoses with extreme caution! All hoses
may contain liquid refrigerant under pressure.
4. m PRESSURIZED TANK CONTAINS LIQUID
REFRIGERANT. NEVER OVERFILLSTORAGE
TANKS. OVERFILLING OF THE TANK MAY
CAUSE AVIOLENTEXPLOSIONANDPOSSIBLE
INJURY OR DEATH.DONOT: Exceedthe working
pressure of Recovery Tank cylinder.
5. m Warning: DO NOT: Exceed the working pres-
sure of each cylinder. Recovery cylinders are
designed for different pressures.Your RG5410A
is not supplied with a recovery tank, it requires the
use of tanks with a minimum of 350 psi working
pressure and PROMAX strongly recom-
mends the use of 400 psi tanks.
NOTE: The use of a 400 psi tank is
mandatory when recovering R-410A.
See PROMAX Recovery Tanks under Parts and
Accessories section on Page 16.
5. m A scale must be used to avoid overfilling the
storage tank. DO NOT OVERFILL. Tank is full at
80% volume. Tank may explode if filled more than
80% due to liquid expansion.
7. Read all safety information regarding the safe
handling of refrigerant and refrigerant oil, includ-
ing the Material Safety Data Sheet. MSDS
sheets can be obtained from your refrigerant
supplier.
8. If you expect temperatures in excess of 135° F,
contact the refrigerant supplier.
9. Be sure that any room where you are working is
thoroughly ventilated, especially if a leak is suspected. Refrigerant vapor is hazardous to your
health and can cause death.
10. m Avoid breathingA/Crefrigerantand lubrica-
tion vapor or mist. Exposure may irritate eyes,
nose and throat. If accidental system discharge
occurs,ventilateworkareabeforeresuming service.
11. i WARNING:TOREDUCE THE RISKOF FIRE:
• Never operate unit inanexplosiveenvironment!
Do not use this equipment in the vicinity of
spilled or open containers of gasoline or any
other flammable liquid.
• When using an extension cord it should be a
3-wire, 14 AWG minimum and no longer than
25 feet.
• Usethisequipment in locationswithmechanical
ventilation that provides at least four air
changes per hour or locate the equipment at
least 18 inches above the floor.
• Never use oxygen when testing for leaks. Any
oil in contact with oxygen under pressure will
form an explosive mixture.
12. c High voltage electricity inside panels.
Risk of electrical shock. Be sure to disconnect
theunitfrom thepowersource before servicing it.
13. To reduce the risk of injury, care should be
taken when moving this equipment.

OPERATING GUIDELINES
m Before operating the RG5410A recovery unit,
read the following m
1. RG5410A IS APPROVED FOR USE WITH THE
FOLLOWING CATEGORY III, IV and V REFRIGERANTS (Per ARI 740):
R-12, R-22, R-134A, R-401A, R-401B, R-401C,
R-402A,R-402-B,R-404A,R-406A,R-407A,R-407-B,
R-407C, R-407D, R-408A, R-409A, R-410A,R-411A,
R-411B, R-412A, R-500, R-502, R-507 and R-509
2. A FILTER must always be used and should
replaced frequently. We recommend that a clean
filter be used for every service job.
Failure to use a filter will invalidate your warranty.
The use of a filter will greatly reduce the risk of
damage to your RG5410A, by preventing
foreign material from entering the unit.
3. Each filter should be labeled and used exclusively
for one type of refrigerant only.
4. Always open service and cylinder valves slowly.
This allows rapid control of the flow of gases if
there is any danger. Once it is determined that
there is no danger, the valves can be opened
fully.
5. Always isolate large amounts of refrigerant and
close off valves after use, so if a leak should
develop anywhere in the system, the refrigerant
will not escape.
6. Keep all connections to the refrigeration system
thoroughly dry and clean. If moisture enters the
refrigeration system, it is likely to cause considerable damage.
7. Promax strongly recommends the use of the
optional 80% Capacity Shutoff Kit (p/n KT-5001).
When installed and used with a recovery tank that
has an internal float switch, the RG5410A will
shut down automatically when the tank is 80% full.
Your RG5410A is pre-wired from the factory for
this kit. Note: The RG5410A is also available in
model RG541OA-KT, with the 80% Shutoff Kit
installed direct from the factory.
8. m A CAUTION: Use only authorized refillable
refrigerant recovery tanks. Federal regulations
require refrigerant to be transported only in
containers meeting DOT spec. 4BA or 4BW.
NEVER use a standard disposable 301b. ta, .1% (the
type of container in which virgin refrigerant is sold) to
recover refrigerant.
9. m A scale must be used to avoid overfilling the
storage tank. DO NOT OVERFILL. Tank is full at
80% volume. Tank may explode if filled more than
80% due to liquid expansion. Below is a repre-
sentative sample for R-22 refrigerant:
TANK SIZE MAX NETWEIGHT
30 lb. Tank 24 lbs.
50 lb. Tank 40 lbs.
Note: Promax strongly recommends the use of the
ADS-100 Refrigerant Scale for monitoring tank
capacity.
10. Your RG5410A has two Internal Pressure
Shut Off switches, a standard 400psi and
a 550psi (when the High Pressure (R410A)
switch is engaged). The shut off switches will
automatically reset after the pressure drops
below 200 psi.
m WARNING: The Internal Pressure Shut Off
Switches do 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.
11. When recovering large amounts of liquid, use the
"Push/Pull method (see diagram on page 13).
m CAUTION: When using the "Push/Pull" method,
once the "Push/Pull" siphon is started, it can continue and overfill the storage tank even if the tank is
equipped with a "shut off" float sensor. The siphon
can continue even after the machine is turned off.
You must manually close the valves on the tank and
the unit to prevent overfilling of the recovery tank.
12. Always operate the unit on a flat level surface.
13. To achieve the deepest final vacuum, use the
tank cooling method to lower the head pressure
on the recovery tank. (See Pages 13 & 14).
Repeat as necessary to achieve the desired
vacuum level.
5
OPERATING GUIDELINES - cont.
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.
14. If the tank pressure exceeds 300 psi, use the tank
cooling procedure to reduce the tank pressure.
(See Pages 13 & 14)
CARE AND MAINTENANCE OF YOUR RG5410A
1. USE of a filter/dryer at the inlet is mandatory. A fil-
ter/dryer must always be used between the recovery machine and the inlet hose.
2. 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 )When
you have finished recovering from the system,
flush your RG5410A with a small amount of
clean refrigerant and refrigerant oil to purge off
any foreign substances left in the unit.
3. Always empty refrigerant from the RG5410A
into a storage tank; see Self-Purge/Auto Evacuate
15.To maximize recovery rates, use the shortest
possible length of 3/8" or larger hose.
A hose no longer than 3 feet is recom-
mended.
16.For maximum throughput, always remove all
unnecessary hose core depressors and the
Schrader valves from port connections.
17.Deformed rubber seals and core depressors in
hoses and faulty or unnecessary Schrader
valves can restrict flow up to 90%.
procedure on Page 12. Liquid refrigerant left in
theRG5410A’s condenser may expand,causing
damage to components.
4. c Warning! Whenever you perform any type of
maintenance work on your RG5410A, insure
that it is disconnected from the power supply
before you begin.
5. If the unit is to be stored or not used for any
length of time, we recommend that it be complenty evacuated of any residual refrigerant and
purged with dry nitrogen.

ADDITIONAL RECOVERY TANK INFORMATION
m Warning: Also read the information pertain-
ing to recovery tanks, previously listed under
Safety Information and Operating Guidelines.
1. CAUTION: NEVER use a standard disposable
30 lb. (the type of container in which virgin refrigerant is sold) to recover refrigerant.
Use ONLY authorized refillable refrigerant tanks.
Federal regulations require refrigerant to be trans
ported only in containers meeting DOT specs.

tank, evacuate it and purge the tank using dry
nitrogen, and then re-evacuate it.
3. Always store refrigerant containers in a cool dry
place.
5. Do not mix refrigerants in a system, a tank or any
where else. Each type of refrigerant must have its
own tank, filter, etc.
6. Storage cylinders sometimes have valves that are
not properly seated when manufactured. Keeping
caps on these valves will guard against refrigerant
leakage.
7. Do not exceed 80% of tank capacity. PROMAX
strongly recommends the use of the Promax ADS100 Refrigerant Scale for monitoring tank capacity.
Safety codes recommend that closed tanks not be
filled over 80% of volume with liquid. The remaining 20% is called head pressure room.
8. If you expect temperatures in excess of 135º F
contact the refrigerant supplier.
3. Tanks and filters should be designated for one
refrigerant only. Before using a tank previously
used for another refrigerant, completely empty the
