Input line fusing: type T2,5A H 250V
20mm time-delayed fuse, located in a
fuseholder in the centre of the switch-
plate at the rear of the pump.
Power interruption: This pump has
an auto-restart feature which, when
active, will restore the pump to the
operating state it was in when power
was lost. See 18.12 Auto-restart.
Stop / start power cycles: Do not
power up/power down for more than
100 starts per hour, whether manually or
by means of the auto-restart facility. We
recommend remote control where a high
frequency of power cycles is required.
