Warning
Tubing may have crack due to wear. It results in the overflow of
fluid from tubing. In that time human body and instruments may be hurt. Must
check usually and change tubing in time.
Please connect directly the power line to the wall socket, and avoid
using the extension electric line.
If power line or plug have wear and other damage, please unplug it.
If following situations happened, please turn off the pump, take off
the power plug.
1. Fluid splash on the pump.
2. You think the pump need to maintain or repair.
The user’s power socket must have ground wire, and have reliable
grounding.
Note: When connect foot pedal switch or external control, must turn off the
pump.

maximum speed is 600rpm, the analog signal voltage range has a linear relationship
with the motor speed.
If the maximum speed is not 600 rpm, the motor speed will be limited by the analog
signal. When the motor speed and the analog signal amount reach the set maximum
speed according to the corresponding proportional relationship, then when the analog
signal amount is increased, the motor speed is set by The operation at a fixed
maximum speed does not follow the increase of analog signal quantity. For example:
