The battery back-up system is designed especially for where the consequence of a primary pump failure through either mechanical failure or loss of mains power would be a flooding situation.
The system comprises of a control panel, 24V back-up pump, 3 no. float switches and a non-return valve.
1. Select a suitable location for the control panel, taking into account that the panel must be located within 4 metres of the pump. It is important to bear in mind access to the control panel for maintenance, ensuring it is located in a dry area and the alarm is audible to the end user.
2. Mount the panel to a wall or backboard using the mounting points at the back of the panel and appropriate screws and wall plugs (not supplied).
3. The pump is suitable for connection to 1¼” PVC pipework. All joins in the discharge line must be made with solvent cement, under no circumstances should push fit or compression fittings be used.
4. Once the primary and back-up pumps are connected to the discharge line ensuring that a separate non-return valve is used on both pumps.
5. The three float switches need to be fixed to the metal bracket (supplied) using the fittings provided (plastic washer and nut). Place the float switches into position ensuring that the activation arm is down and fixed into position using the plastic washer and nut.
6. The float switches should be located within the tank ensuring that the following configuration is adhered to:
7. The electrical/float cables should be drawn through a cable duct back to the control panel and the appropriate wiring connections should then be made from the 24V pump and float switches to the panel in accordance to the wiring diagram provided. (Please refer to Section 6.0 of this document).
8. The control panel should be connected to a 240V, 13 amp fused spur by a suitably qualified person in accordance with the Institute of Electrical Engineers Regulations.
9. For connection to the mains supply it is imperative that the panel is connected to a separate power supply to that of the primary pump. This is because should a fault occur with the primary pump and blow its fuse, then the back-up system can still operate.
10. Please ensure that there is suitable slack on the cable to allow for the pump to be removed for maintenance.
To commission the control panel you must connect both the batteries using the connectors provided, a red indicator on the battery charger will inform you that the batteries are now charging, once fully charged the red indicator will turn green. To test the system, disconnect the primary pump from the mains power and fill the tank with water until the back-up pump activates. Please note that prior to the back-up pump activating the high level alarm should sound.
Control Panel Operation
The most important element of the battery back-up system is the control panel as it controls and monitors the status of the complete system.
The panel consists of both visual and audio indicators that are imperative for both the installer and end user to fully understand.
The battery back-up system comes complete with an audio alarm to alert the user when there is a high level situation within the tank. Also located on the front of the panel is an alarm mute button to silence the alarm in a high level situation.
It is advised that the operation of the battery back-up pump system is checked every 6 months; this can be done by removing the power supply to the primary pump and allowing the tank to fill with water until the back-up pump activates.
It is also advised that every 6 months the system is allowed to operate using only the back-up pump, this is to allow the batteries to run down and fully recharge which in turn will help to extend the life of the batteries.
Is also recommended that the battery back-up pump be removed every 6 months to ensure that there is no build up of debris around the pump and float switches.
