Connecting a high level alarm mini float to the Delta Battery Backup
4.3.1 Mounting a high level alarm mini float (Delta Dual V3/V4/V6)
Please refer to the specific installation and operating guidelines for the chamber/sump when installing the float switch.
The mini float switch is supplied with a 5 m cable. If you require more than 5 metres please contact Delta Membranes on
01992 523 523 between 8am and 5pm, Monday to Friday or by email at info@deltamembranes.com for assistance.
1.
The mini float switch should be positioned between the activation points of the two pumps, as shown in Figure 7. This will
cause the alarm to trigger if Pump 1 has failed, before Pump 2 empties the chamber. This periodic triggering is a useful
indicator that there is a fault in the pumping station.
2.
The mini float switch should be installed in the float shroud. The float shroud should be positioned on the vertical pipework
of the rear pump so that it butts up to the base of the elbow and secured with cable ties. See Figure 8.
3.
When positioning the mini float switch insert the float cable through the green washer.
4.
Place the mini float switch into position with the activation arm located in the downwards position as shown in Figure 9.
5.
Insert the mini float cable through the blue plastic washer and nut and tighten fully.
6.
Cable to be drawn through cable duct between the chamber/sump and control panel location for removal at a later date.
