1) This motor houses an automatic returning thermal protector, which may be activated in case of trouble. Motor will restart automatically when temperature goes down. If the thermal protector is activated, switch off the power immediately for safety purpose.

2) Never block the outlet or operate the pump with equipment mounted at the outlet side that blocks the passage of gas.
Otherwise, the internal pump pressure will increase causing the oil level gauge to protrude, the motor to be overloaded, or eventhe pump to explode.
