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 tank until 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.
Remove the connecting pipe.

Safety Precautions
WARNING!
To avoid personal injury, please carefully read and follow the
instructions in this manual.
Always wear goggles when handling air-conditioning refrigerant.
Do not contact the refrigerant directly! A personal injury may occur.
Hot surface! Do not touch the oil tank or pump casing while operat-
ing the pump.
Risk of electrical shock! Make sure all equipment is properly ground-
ed when connecting the power supply.
The pump is not allowed to operate for more than 3 minutes while
the inlet is exposed to the atmosphere.
The ambient temperature for proper operation is
5°C-40°C(41°F-104°F).
The voltage of the pump is 110V±10%~60Hz. The power socket must
be grounded.
The pump body will be damaged to take out the refrigerant when
the pump chamber is pressurized. It is recommended to use special
equipment to do this work.
Maintenance
1. Pump oil selection
It's important to select the proper vacuum pump oil to achieve the
desired ultimate vacuum. To ensure the best performance of the pump,
it is recommended to use vacuum pump oil with a low viscosity grade
of 32 - 46.
The pump oil must be repaced immediately while it is emulsified or
contaminated.
Operate the pump for about one minute to warm it up before chang-
ing the oil;
Open the inlet when the pump is running so that the oil in the pump
chamber is forced to flow out. Switch off the pump and remove the
drain plug to drain the oil. Keep the drained oil in a suitable vessel
and dispose of it properly;
Tilt the pump body towards the drain plug to completely empty the
pump chamber;
Tighten the drain plug;
Remove the filling plug and add new pump oil;
Tighten the inlet cap, operate the pump for one minute, and check
the oil level. In case the oil level is below the MIN position on the oil
sight gass, fill the oil to a level between the MAX and MIN positions.
Install the oil mist trap.
