When you keep it, without using a pump for a long period of time, please put
pump oil into a pump and seal a inlet port.
Oil is not put into a pump, but
if it is kept where a inlet port is opened wide, water absorption may expand
vanes of a pump and a pump may stop rotating.
Please do not leave it, where moisture is sucked. If it is left with moisture
sucked, since water absorption expansion of vanes and the corrosion of pump
parts will be promoted, a pump may stop rotating.
0.5 Protective device
The pump is equipped with a single-phase 100-120 V (50/60 Hz) and 200-240 V (50/60 Hz)
motor.
An overload protector (Auto reset thermal protector) is incorporated.
The use of another protective device (such as an earth leakage breaker) in addition to the
overload protector is recommended.
This motor houses an automatic returning thermal protector, which may be
activated in case of trouble. The motor will restart automatically when the
temperature goes down to 78
±
9℃.
If the thermal protector is activated, switch off the power immediately for safety
reason.
Use the pump only at the rated voltage. Use at other than the rated voltage
will interfere with correct operation of the overload protector, and result
in the motor burning out, or fire.
