7.7
7.9 Starting
Select the desired operating mode with the switch on the control panel.
– Continuous operation
Turn the switch on the control panel to the left (position 2). Due to the built in start-
up delay, it may take a moment before the motor actually starts.
– Level protection
Turn the switch on the control panel to the right (position 3). The pump will cycle on
and off depending on the level of the liquid being pumped.
Check the level of both float switches before doing this.
Note
When float switches are used it is important that the pump unit cycle on and off no
more than four times per hour. Keep this in mind when positioning the float
switches.
Note
The pump must always be at a complete standstill when the position of the switch is changed.
7.10 Stopping
1. Turn the switch on the control panel to position (1).
2. Observe whether the system comes to a gradual, smooth stop.
3. Perform the general steps for shutting down the pump (see chapter 7).
