VB Series vacuum pumps are used to create a vacuum by evacuating
gas from a sealed vessel. The pumps are applicable for refrigeration
maintenance to charge CFC, HCFH, and HFC refrigerants such as
R12/R22/R134a (the R32 version can be used for R32 and 1234yf) and air
extraction in printing machines, food processing, gas analysis, thermo-
pastic molding, etc. In some cases, they can be used as fore pumps for
high vacuum equipment.
1. High Ultimate Vacuum and High Pumping Speed
High ultimate vacuum and high pumping speed are achieved by taking
integral cylinder construction with high precision.
2. High-Efficiency Filtration
A high-quality filter element is used to reduce oil mist effectively.
3. Comfortable, Robust Handle
Made with a softened rubber-lined handle, this device is comfortable
to carry and use.
4. Elegant Appearance
Unique and elegant appearance with square-shaped pump casing and
fan cover.
Preparation
Operation
Make sure the power supply matches the voltage and frequency
marked on the pump data pate.
Make sure the switch is in the OFF position before connecting elec-
trical power to the pump.
Fill the oil till the oil level reaches the middle position on the oil
sight gass. A low oil level will cause pump performance loss while a
high oil level may result in oil spraying.

Before using the vacuum pump, remove the inlet cap and connect
the pump to the sealed vessel (Check and make sure the thread of
the pipe fits that of the inlet port). The length of the connecting pipe
shall be as short as possible.
Check and make sure the air inlet is well-sealed and without any
leakage.
Switch on the pump to start operation.
Close the valve between the pump and the sealed vessel when the
operation is finished.
Switch off the pump and remove the power plug.
