Problem
TMP doesn't reach
NORMAL
OPERATION
System will not start
Poor ultimate
pressure
Hammering noise
Internal Scroll Pump
runs intermittently
Overtemperature
* The internal Scroll Pump is equipped with an auto-reset thermal motor protector.
This protector automatically shuts down the pump when it detects an overload
condition, and automatically restarts the pump when the motor has cooled to
within an acceptable temperature range.
Overtemperature:
CAUTION
To prevent damage to the pump when the temperature exceeds 60 °C,
the sensor automatically cuts off the power supply.
