VacuMaster® High
Performance Vacuum Pumps
Congratulations on purchasing one of Robinair’s
top quality VacuMaster
pump has been engineered specifically for air
conditioning and refrigeration service, and is built
with Robinair’s proven offset rotary vane for fast,
thorough evacuation.
You’ll appreciate these key features...
Iso-Valve
Allows the pump to be shut off while still connected to the A/C-R system, which is handy for
checking rate of rise. With the valve handle in the
“Open” position, the pump is open to the system
being evacuated. In the “Close” position, the pump
is isolated from the system.
High vacuum rating
The two-stage, offset rotary vane design provides
powerful, quiet high vacuum capability and
assures moisture removal, while the high pumping
capacity reduces evacuation time.
Lifetime Filtration
The intake filter prevents foreign matter from
entering the pumping chamber, and an exhaust
filter separates oil vapor from the exhaust flow.
Gas ballast
A precise amount of atmospheric air is introduced
into the pump, preventing condensation of
moisture vapor and helping maintain the purity of
the pump oil. By using the gas ballast, the pump
operates more efficiently and pump life is extended.
Sure-grip handle
The one-piece, molded handle makes it easy to
carry the pump to and from job sites, and the
handle stays cool to the touch during operation.
Compact design
Your pump measures approximately 42 cm
(16
rotary vanes keep the pump weight low, making
it easy to carry.

cause injury.
Improper use or connections may cause
electrical shock hazards. Read and follow the
instructions carefully and take precautions to
avoid electrical shock hazards. Be sure that all
associated devices are properly grounded before
energizing circuits.
The normal operating temperature will cause
certain external portions of the pump to be hot to
the touch. Do not touch the pump housing or
motor during operation.

Before using your
vacuum pump
In all cases, motors are designed for operating
voltages plus or minus 10% of the normal rating
(see SPECIFICATIONS). Single voltage motors
are supplied fully connected and ready to
operate.
1. Check to make certain the voltage and
frequency at the outlet match the specifications on the pump motor decal. Check the
ON-OFF switch to be sure it is in the OFF
position before you plug the pump into an
outlet. Check to be certain the gas ballast
valve is closed. Remove and discard the red
plastic plug from the top of the oil reservoir.
Failure To Remove Red Plastic Caplug
May Result In Bodily Injury.
2. The pump is shipped without oil in the
reservoir. Before starting the pump, fill with
oil until oil just shows in the bottom of the
sight glass. The approximate oil capacity of
the pump is 488 milliliters (16
3. Thread in the exhaust filter (hand tighten)
and remove the cap from one of the inlet
ports. Turn the Iso-Valve to OPEN. Turn the
motor switch to ON. When the pump runs
smoothly, turn the Iso-Valve to CLOSED and
replace the cap on the inlet port. This may
take from two to 30 seconds depending on
the ambient temperature. After the pump
runs for approximately one minute, check the
sight glass for proper oil level — oil should be
even with the sight glass OIL LEVEL line.
Add oil if necessary.
When the pump is running, the oil level should be
even with the OIL LEVEL line. Underfilling will
result in poor vacuum performance. Overfilling
can result in oil blowing from the exhaust.
Your pump is now ready to evacuate air conditioning and refrigeration systems. Follow normal
service procedures and the A/C-R manufacturer’s
instructions for connections to the system.
CAUTION! Before connecting your vacuum pump
to an A/C-R system, remove refrigerant from the
system in an accepted manner. Damage to the
pump may occur if evacuation is started while the
system is under high pressure. Robinair recommends use of our Refrigerant Recovery and
Recycling equipment.

Operating Manual
Wiring Instructions (15121A):
The VacuMaster vacuum pump features dual voltage ranges. Before operating the pump, read and
follow these rewiring instructions (if necessary) to
be sure your pump is wired for the appropriate
voltage.
CAUTION! Unplug the unit before beginning any
service work. Improper use or connections can
cause electrical shock. Only qualified personnel
should perform service work.
The VacuMaster vacuum pump is factory wired
for a high voltage of 220 volts. To wire the switch
for a low voltage range of 110 volts to 127 volts,
follow these steps.
1. Disconnect the unit from the AC power
source before proceeding.
2. Loosen the screws on the plate at the rear of
the motor, and carefully move the plate aside
to clear the opening.
3. Disconnect the leads and reconnect for low
voltage, following the diagram and chart.
(High voltage connections are also shown
if you want to rewire at some time.)
4. Check to see that all connections are secure
and that there are no short circuits. Be sure
the grounding connector is properly connected.
5. Re-install the plate on the rear of motor with
the screws which were loosened in Step 2.
IMPORTANT: Check for short circuits using a
continuity tester before reconnecting to the AC
power source.
15121A
To use the gas ballast feature
Moisture from the A/C-R system that is carried
into the pump as a vapor tends to condense into a
liquid and combine with the vacuum pump oil.
When moisture contaminates the pump oil, it
reduces the pump’s ability to reach its ultimate
deep vacuum level.
The gas ballast valve purges a small amount of
atmospheric air through the exhaust chamber.
This extra volume of air mixes with the vapor from
the refrigerant system to prevent condensation
and to help exhaust moisture in the form of vapor
from the pump.
To use the gas ballast, start the pump and open
4
the gas ballast valve until the system has reached
approximately 1000-3000 microns. Close the valve
to allow the pump to pull down to its ultimate
vacuum level. The gas ballast valve is located
beside the handle, opposite the inlet fitting.
The gas ballast valve may be opened or closed at
any time during pump operation. It is fully open at
two turns counterclockwise.
NOTE: Robinair recommends the use of a
thermistor vacuum gauge to most accurately
measure vacuum levels.
To shut down your
pump after use
To help prolong pump life and promote easy
starting, follow these procedures for shutdown:
1. Close the manifold valve between the pump
and the system.
2. Turn the Iso-Valve to the CLOSED position.
3. Remove the hose from the pump inlet.
4. Turn the pump power switch to OFF, then return
the Iso-Valve to the OPEN position for a few
seconds to relieve any vacuum inside the pump.
5. Cap the inlet port to prevent any contamination or loose particles from entering the port.
To maintain your high
vacuum pump
For maximum performance, Robinair recommends
changing vacuum pump oil after each use.
Vacuum pump oil
The condition and type of oil used in any high
vacuum pump are extremely important in determining the ultimate attainable vacuum. Robinair recommends the use of our Premium High Vacuum
Pump Oil. This oil has been specifically blended to
maintain maximum viscosity at normal running
temperatures and to improve cold weather starts.
Robinair Premium High Vacuum Pump Oil is
available in convenient pint, quart or gallon
containers. Order by part number:
13201 — Pint (shipped 12 pints per case)
13203 — Quart (shipped 12 quarts per case)
13204 — Gallon (shipped 4 gallons per case)
Oil change procedure
1. Be sure the pump is warmed up.
2. Remove the OIL DRAIN cap. Drain contaminated oil into a suitable container and dispose
of properly. Oil can be forced from the pump
by opening the inlet and partially blocking the
exhaust with a cloth while the pump is
running. Do not operate the pump for more
than 20 seconds using this method.
3. When the flow of oil has stopped, tilt the
pump forward to drain residual oil.
Operating Manual
4. Replace the OIL DRAIN cap. Remove the
exhaust filter and fill the reservoir with new
vacuum pump oil until the oil just shows at the
bottom of the sight glass. The approximate oil
1
capacity of the pump is 488 milliliters (16
/
2
ounces).
5. Be sure the inlet ports are capped, then turn
ON the pump. Allow it to run for one minute,
then check the oil level. If the oil is below the
sight glass OIL LEVEL line, add oil slowly
(with the pump running) until the oil reaches
the OIL LEVEL line. Replace the exhaust filter
(hand tighten), making sure the inlet is
capped and the drain cap is tight.
6. If the oil is badly contaminated with sludge
that forms when water is allowed to collect in
the oil, you may need to remove the oil
reservoir cover and wipe it out.
Repeat this procedure as required until the
contamination is removed. Replace the OIL
DRAIN cap and refill the reservoir to the proper
level with fresh pump oil (see Step 4).
Cleaning your pump
Clean the pump with soap and water only. Do not
use commercial cleaners that contain degreasing
agents that can damage polycarbonates. The
pump handle and base are made of Lexan*, one
of the toughest polycarbonate plastics available.
However, it is sensitive to degreasing agents.
*Lexan is a registered trademark of General Electric
Motor lubrication
After three years of normal service or one year of
heavy-duty service, add oil annually. Use electric
motor oil or SAE 10 oil.
Troubleshooting guide
Your VacuMaster pump has been designed for dependable use and long life. If something should go
wrong, however, the following guide will help you get
the pump back into service as quickly as possible.
If disassembly of the pump is required, please
check your warranty. The warranty may be voided
by misuse or customer tampering which results in
the pump being inoperable.
Failure to start
Check the line voltage. Robinair pumps are designed to start at +
At extremes, however, switching between the start
and run windings may occur.
Oil leakage
1. Be sure the oil is not a residual accumulation
from spillage, etc.
2. If leakage exists, the module cover gasket or
the shaft seal may need replacing. Follow the
instructions in the seal replacement kit, part
number 15367. If leakage exists in the area of
the oil drain plug, you may need to reseal the
plug using a commercial pipe thread sealer.
10% line voltage at 0oC (32oF).
Failure to pull a good vacuum
1. Be sure the Iso-Valve is in the OPEN position.
2. Be sure the vacuum gauge and all connections
are in good conditon and leak-free. You can
confirm leakage by monitoring the vacuum
with a thermistor gauge while applying vacuum
pump oil at connections or suspected leak
points. The vacuum will improve briefly while
the oil is sealing the leak.
3. Be sure the pump oil is clean. A badly
contaminated pump may require several oil
flushes. See OIL CHANGE PROCEDURE.
NOTE: Use only high vacuum pump oil such as
Robinair’s Premium High Vacuum Pump Oil. Other
oils will prevent pull-down to a deep vacuum.
4. Be sure the gas ballast knob is tightly closed.
5. Be sure the oil is at the proper level. For
maximum pump operation, the oil must be
even with the OIL LEVEL line on the sight
glass when the pump is running. Do not
overfill. To check the oil level, start the pump
with the inlet capped. Add oil if necessary.

conectada todavía al sistema de A/C-R, lo cual es
conveniente para controlar el ritmo de aumento.
Con el mango de la válvula en la posición “Open,”
la bomba está abierta al sistema que está siendo
evacuado. En la posición “Close,” la bomba está
aislada del sistema.
Alto vacío nominal
El diseño del álabe rotatorio compensado de dos
etapas ofrece una capacidad de alto vacío
poderosa, pero silenciosa, y asegura la
eliminación de la humedad, mientras que la fuerte
capacidad de bombeo reduce el tiempo de
evacuación.
Filtración durante la Vida Util
El filtro de entrada evita que materias extrañas
entren a la cámara de bombeo, y un filtro de
escape separa el vapor de aceite del flujo de
escape.
Balasto de gas
Una cantidad precisa de aire atmosférico se
introduce en la bomba, previniendo la condensación del vapor de humedad y ayudando a mantener la pureza del aceite de la bomba. Al utilizar
el balasto de gas, la bomba opera con mayor
eficiencia y se extiende la vida de la bomba.
Mango de agarre seguro
El mango moldeado de una sola pieza hace que
sea fácil de transportar la bomba a diferentes
lugares de trabajo, y no se calienta durante la
operación.

Manual del Operador
Antes de utilizar
su bomba de vacío
En todos los casos, los motores están diseñados
para voltajes de trabajo con una variación del +
del valor nominal (ver ESPECIFICACIONES).
Los motores de voltaje sencillo se suministran
completamente conectados y listos para functionar.
1. Asegúrese de que el voltaje y la frecuencia
en la salida se conformen con las especificaciones en la calcomanía del motor de la
bomba. Revise el interruptor (ON-OFF) para
asegurar que está en la posición de OFF
antes de enchufar la bomba. Verifique que la
válvula de balasto de gas esté cerrada.
Saque y bote el tapón de plástico del extremo
del filtro de escape.
2. La bomba se envía sin aceite en el
reservorio; antes de arrancarla, hay que
llenarlo de aceite. Saque el filtro de escape
(un tapón hecho de plástico negro que está
directamente al frente al mango) y agregue
aceite justamente hasta que aparezca en el
fondo del tubo indicador. La bomba tiene una
capacidad aproximada de aceite de 375 ml.
3. Reemplace el filtro de escape (apriete a
mano), y remueva la tapa de uno de los
puertos de entrada. Ponga la Iso-válvula en
la posición ABIERTO (Open). Gire el
interruptor de motor a ENCENDIDO (On).
Cuando la bomba funcione suavemente,
ponga la Iso-válvula en la posición
CERRADO (Closed) y reemplace la tapa del
puerto de entrada. Esto puede requerir de
dos a 30 segundos dependiendo de la
temperatura ambiente. Después de que la
bomba funcione por aproximadamente un
minuto, verifique el nivel adecuado del aceite
en el cristal visor — el aceite debe estar
nivelado con la línea de NIVEL DE ACEITE
(Oil level) del cristal visor. Añada más aceite
si es necesario.
Cuando la bomba está funcionando, el aceite debe
estar al nivel de la línea de NIVEL DE ACEITE
(Oil level). Una cantidad demasiado baja resultará
en un vacío deficiente. Una cantidad demasiado
grande resultará en la salida de aceite por el escape.
Ahora su bomba está lista para evacuar sistemas de
aire acondicionado y refrigeración. Para conectar la
bomba al sistema, siga los procedimientos normales
de servicio y las instrucciones del fabricante.
CUIDADO! Antes de conectar la bomba de vacío
al sistema de A/C-R, elimine el refrigerante del
sistema de una manera aceptable. Pueden
producirse daños en la bomba si se inicia la
evacuación mientras el sistema está bajo mucha
presión. La Robinair recomienda el uso de
nuestros equipos de Recuperación y Reciclaje de
Refrigerantes.
