4.1 Cautions for Operation
See Danger (1)(2), P04
See Warning (8), P04 (12)(13)(14), P05
See Caution (5)(7)(8), P06
See Note (2)(3)(4)(5)(6)(7)(8)(9), P07
4.2 Operation of the Thermal Protector
1) When the thermal protector operates, switch the pump power supply OFF (set to O),
remove the power cord from the outlet, and contact the manufacturer. Note that the motor
will be very hot and should not be touched.
2) Once the cause of the fault has been removed, wait until the motor cools and restart
operation.
See Caution (6), P06
4.3 Starting in Cold Weather
Cold weather will increase the viscosity of bearing grease and harden diaphragms, resulting in
the pump being difficult to start. Follow the procedure below in such conditions.
1) Turn the switch ON/OFF 2~3 times with the inlet open to atmosphere until the pump starts.
If the pump still does not start, raise the ambient temperature to beyond 0°C.
2) With the inlet open to atmosphere, run the pump for a few minutes to warm it.
3) Commence normal operation once the pump has warmed.
