6.1 Routine Inspection

Check periodically that ALARM signal is not output on the controller or remote output. When the
WARNING/ALARM display appears, take action in accordance with Section 8. "Troubleshooting".
!
Keep the power supply to the pump turned off until you have finished the wiring and
connecting work. Also remove the power connector and interrupt the Circuit Protector (CP)
during this.
!
Avoid contact and keep inflammable substances out of reach. Do not remove the outer
cover during operation. The pump unit and the inlet piping and exhaust piping will remain
at a high temperature during operation and for a short time after the pump has stopped.
Even when the cause of the WARNING/ALARM signal has been removed the signal will be
maintained until the RESET signal is entered. After you have taken the remedial action, press the
RESET button on the controller or enter the RESET signal from the control signal connector to reset
the WARNING.
!
Check the pump according to "8. Troubleshooting" before stopping suddenly. This pump
doesn't stop by signal "WARNING". But signal "ALARM" or serious trouble occurs in a pump
when pump driving is continued.
!
Do not start the pump when a WARNING/ALARM has been generated. After you have taken
the remedial actions, reset the pump.
If any abnormal symptoms other than those displayed on the LCD controller appear, take action in
accordance with the instruction of Section 8. "Troubleshooting".
