4.5 Thermal protector
A automatic reset thermal protector is incorporated in the motor in order to
interrupt the power circuit of the motor and prevent damage to the motor when
an over current flows through the motor due to a stop in rotation or overload
resulting from the pump malfunctioning during operation.

When the thermal protector has been actuated, turn off the switch
and contact us.
The motor is very hot when the thermal protector has actuated. Never touch it
with your hand.
When the cause of the malfunction has been eliminated, check that the motor
has cooled down, turn on the switch to restart operation (see ｢6.5 Trouble
shooting list｣).
Firing hazard. As the surface of the pump body is higher temperature(70～
80℃) during operation, do not touch it until cooled down after stopping the
pump.
4.6 Set up oil mist trap (option)
Oil mist trap OMT-050A for G-5DA,G-10DA can be equipped for trapping oil mist
out of the pump. After eliminating the standard exhaust port, equip the oil mist
trap to the exhaust port. This can reduce oil mists and exhausting noise. Read
the instruction manual of the oil mist trap in detail.
