Connecting a high level alarm sump float to the Delta Battery Backup
4.4.1 Mounting a high level alarm sump float (Delta Foul V3, Delta 800 Series)
Please refer to the specific installation and operating guidelines for the chamber/sump when installing the float switch.
The sump float switch is supplied with a 10 m cable. Should you require more than 10 metres contact Delta Membranes on
01992 523 523 between 8am and 5pm, Monday to Friday or by email at info@deltamembranes.com for assistance.
1.
Please ensure you position the sump float switch higher than the primary pump activation point contained within, as shown
in Figure 11, 12 or 13.
2.
Install the sump float switch cable securely. The sump float switch should be installed using a float bracket. The Delta Foul
V3 chamber features an integral float bracket. 800 Series chambers feature a steel float bracket.
3.
Attach the counterweight approximately 70 mm from the top of the float switch. You must separate the counterweight
by removing the centre screw using a 6 mm Allen key, once separated you will see two grooves, using the smaller of the
grooves position the cable into place and put the counterweight back together ensuring the centre screw is tightened.
4.
Pull the float cable through the M20 cable gland on the float bracket. Position the sump float switch higher than the
primary pump activation point. Once the float has been positioned tighten the M20 gland.
5.
Fix the cable into position using a cable tie to ensure the float doesn't drop down.
6.
Cable to be drawn through cable duct between the chamber/sump and control panel location for removal at a later date.
