Error
The product features the detection function for breakages of the pressure sensor.
｢Er01｣ appears blinking on the indicator(and two japanese
letters appear on the blind window) when breakages of the
pressure sensor occurred. The solenoid valve for control
shuts, the leak valve opens.
During Power Failure
In case of power failure, the leak valve opens, the atmosphere in the system of the rotary
evaporator is released, and the solenoid valve for control is shut. It prevents spout of organic
solvent in distillation, and back-flow of water from the aspirator.
After Power Failure
After power failure was repaired, the set mode is automatically switched to the fixed value
control. The indicator displays the set pressure blinking. The leak valve opens and the leak
lamp is on. The solenoid valve for control shuts. The fixed value control lamp blinks and the
set lamp is on.

Make sure that the cooling circulating device or others are working properly when the vacuum control is

Caution Caution Caution Caution
The product is not interlocked with neither the rotary evaporator nor bath. Care should be
taken that each movement of them are not the same after the power failure. If power fails
while the evaporator is revolving, it starts to revolve after power failure was repaired.
