User Manual

This instrument is designed for laboratory usage only. Please read this manual
carefully before installing and operating. The instrument shall not be modified in
any way. Any modification will void the warranty and may result in potential hazard.
We are not responsible for any injury or damage caused by any non-intended
purposes and modifying the instrument without authorization.
1. Check the voltage specified on the name plate and ensure it matches the line
voltage in your location.
2. Install the instrument in a clean, dust-less and ventilated area under 40℃.
3. Never use the pump with any flammable gas or toxic material.
4. The pump is not designed to start against applied vacuum. To prevent
damage, verify that the pump inlet is at atmospheric pressure before each
start. If necessary, the inlet can be vented to atmosphere by partially
unscrewing the vacuum regulator knob.
5. When finish pumping, please do not turn off the pump at once and continue
to run the vacuum pump for at least two minutes in order to draw out the
mist and tiny liquid to prolong the service life of the pump.
6. This pump has a thermal protection device that automatically shuts-off when
it becomes overheated.
7. The temperature of the surface of pump is very high after use or during work,
please don’t touch it to avoid being burnt.
8. Do not use any lubricant, which may damage the pump.
9. If the supply cord is damaged, please contact the manufacturer or your
service agent for replacement to avoid hazard.
* Warning: The PTFE-coated diaphragm and chamber can offer good resistance
to a wide range of chemicals except strong acid and alkali.
