green "RUNING" indicator light is on, during the correct work of the regulator. The "RUN", "STOP" and "PROTECT" indicator lights
come on, while new settings are being made. When programming the controller, it is possible to set the parameters:
RUN value - this is the pressure value in the tank, above which the pump will run.
STOP value - this is the pressure value in the tank, after reaching which the pump will stop working. The lowest relative
pressure that can be achieved by the pump is: - 0.98 bar. This corresponds to 20mbar absolute pressure. If the device is
set to a lower value (e.g. -0.99bar), the vacuum pump will run continuously.
PROTECT value - this function is inactive in vacuum piston pumps.
By switching the vacuum pump on and off, the regulator keeps the pressure in the expansion tank constantly between the
RUN and STOP values. When the pressure in the tank rises above the RUN value, the pump starts. When the STOP value is
exceeded, the vacuum pump is stopped.
The operating and programming instructions for the controller can be found in the next chapter of this manual.
WARNING! Points 3-8 only apply to a vacuum piston pump with an expansion tank and a digital vacuum controller.
1) Connect the vacuum piston pump to the vacuum set with which it is to be used.
2) Start the pump by connecting the pump's power cord to the mains supply.
3) When the pump is connected to the mains supply, the pressure regulator is started. After a while, the display will show the
pressure value inside the expansion tank.
a. If the pressure is less than or equal to the RUN value, the pump will not start.
b. If the pressure is higher than the RUN value, pump will run, reducing the pressure to the STOP value. When the STOP
value is exceeded, the pump will be turned off.
4) If the vacuum set is untight or not connected, close the intake air valve (position the valve handle perpendicular to the valve).
This will allow to obtain or maintain the set vacuum pressure inside the expansion tank.
5) Remember to open the intake air valve (position the valve handle parallel to the valve) in order to degassing the components
connected to the tank valve.
6) Pressure is maintained in the expansion tank and controlled by a vacuum controller. When the pressure rises above the RUN
value, the pump starts and runs until the pressure is reduced below the STOP value. If the pressure is equal to or lower than
RUN value, the pump will not start.
7) Use vacuum controller to set or check the RUN and STOP values.
a. Select the parameter to be set / displayed using the "SET" button.
b. The selection of the parameter will be confirmed by the lighting of the red control lamp above the relevant inscription
("RUN", "STOP" or "PROTECT").
c. The display will show the programmed value of the selected parameter.
d. To change the parameter value, use the "+" and "-" buttons.
e. In order to set / display another parameter, perform steps a-d again.
f. The controller automatically remembers the set / displayed value.
8) To disconnect the vacuum set from the expansion tank, first close the intake air valve (position the valve handle perpendicular
to the valve). This allows to maintain the pressure in the expansion tank. To start degassing a new vacuum set, remember to
open the intake air valve after connecting it (position the valve handle parallel to the valve).
9) To turn off the pump, disconnect it from the mains supply.
The vacuum pump should stand on its feet on a horizontal and stable surface, in a dry, clean, low-dust and well-ventilated
place. The distance of the side surfaces of the pump from other objects should not be less than 5cm. The distance between
the front and back of the pump from other objects should not be less than 10cm. If the pump will be installed inside any
device or furniture, provide air inlet to the device from the pump fan side.
Do not allow the vacuum pump to overheat. Exceeding the temperature of 75°C on the motor housing significantly shortens
the life of the pump, and in some cases can lead to its complete damage.
Vacuum piston pumps are not intended for continuous operation. The recommended mode of use is S3 50% intermittent
operation. The maximum time of continuous operation of the pump is 8 hours.

If the pump will not be used for an extended period of time, cover the suction and exhaust gas connections and then put the
pump away in a dry and safe place.
The pump works without oil. Do not fill the pump with oil or lubricate it, as this may damage it.
To protect the inside of the expansion tank from corrosion, open the bottom drain valve every day to get rid of moisture and
water that may have entered it.
The accumulation of fine solid contaminants in the polycarbonate housing of the intake air filter is a natural result of filtration.
The rate of pressure drop during venting gradually decreases. However, if it is not possible to achieve a negative pressure at
the level declared by the distributor, it may indicate the vacuum set untightness.
Read the operating instructions before use.
There are warning decals on the vacuum pump and the expansion tank, read them before starting work and
follow them.
Before each use of the vacuum pump, it is necessary to check its technical condition, in particular the supply
cable of the vacuum pump.
Perform servicing and maintenance of the vacuum piston pump periodically.
Carry out all maintenance work when the pump is not hot and is not running.
The general rules for the use of equipment working under voltage must be observed.
Before starting work, make sure that the parameters of the power source correspond to the pump requirements specified
on the pump.
Make sure that the pump complies with the technological requirements, processes and purposes for which it is to be used.
Make sure that the pump is not exposed to chemicals that could damage it. The customer is solely responsible for selecting
the appropriate pump for the working conditions.
Do not pump flammable, explosive and toxic gases. Do not pump gases that are extremely moist or contain deposits or
dust. If the pumped gases have a harmful effect on health or have a bad effect on the environment, an extension pipe can
be installed at the pump outlet and the gases handled in accordance with environmental standards.
The temperature of pumped gases should not be higher than + 70 °C.
Use the pump in a safe, well-ventilated place, on a flat, stable surface.
Avoid excessive pollution of the working environment by dust, powders, small solids or water, as heavy contamination can
damage the pump.
Do not expose the device to rain or excessive moisture.
Some parts of the vacuum pump get very hot during operation. To prevent burns, never touch the body and pump motor.
Never place in close proximity to the vacuum pump objects flammable, explosive, and susceptible to high temperature.
Do not repair the vacuum pump by yourself.
Never put fingers or other objects inside the pump impeller cover. Keep your hair, clothing, gloves and other objects that
could get into the impeller, away from moving parts.
Do not subject any parts of the human body to under pressure.
The device should be operated by trained technicians, mentally and physically able to operate the vacuum pump.
Keep children and animals away from operating area of the device.
Be foreseeable, watch what you are doing, and be reasonable when using the device. Do not use the device when you are
tired or under the influence of drugs, alcohol or medication.
Do not use the device or any of its parts for purposes other than those for which it was intended. Do not make any
modifications or changes to pump or its individual components. Any modifications and changes are made by the customer
under his sole responsibility and will void the warranty.
Keep the vacuum pump clean. Disconnect the pump from the power supply before cleaning. Cleaning should be done at least
once a month or more frequently if necessary. Pay particular attention to the cleanliness of the intake filter and the muffler filter,
as contamination may adversely affect the flow rate and shorten the life of the pump.
Do not clean the vacuum pump with flammable liquids, solvents or with a stream of water. The pump housing and
components should be cleaned with a dry, soft cloth. If any dirt gets inside the housing, it can be removed with compressed air.
The expansion tank can be cleaned with a damp cloth and a mild detergent. Digital vacuum controller should be cleaned with dry,
soft cloth.
