7. Now connect the pump plug to the "OUTPUT 1 DC 18V" socket on the battery box.
8. Turn the "SYSTEM ON/OFF" switch to "ON". The "SYSTEM" LED indicator lights up GREEN when the battery is charged and the pump can be switched on.
Note: the "SYSTEM" LED indicator is a dual-colour LED. If the display lights up RED then the pump is not working, because the residual charge is insufficient or the battery is being
charged for the first time. The battery is charged after less than one day of sunshine. During charging phase, the "CHARGING" LED indicator shows YELLOW, regardless of whether the
system is switched on or off. The charging process ends automatically once the battery has been charged to its maximum capacity. The charging of the battery always has priority
over operating the pump.
9. Activate the output jack 1 (OUTPUT 1) by pressing the ON/OFF button. If the output
is switched on (ON) the LED indicator shows GREEN and the pump starts working.
To stop the pump, switch off the output jack 1 by pressing the ON/OFF button.
10. The pump connected to the output jack 1 can be operated either in continuous
mode or interval mode with the "TIMER ON/OFF" button.
- TIMER OFF continuous mode, i.e. interval mode is deactivated and the pump runs
continuously. This mode is only available when the SYSTEM LED indicator is
showing green.
- TIMER ON interval mode, i.e. the pump operates for 10 minutes per hour.
This mode is useful for saving battery capacity, e.g. on cloudy days.
11. Output jack 2 (OUTPUT 2) provides of 6 volt DC supply for optional
ancillary devices, for example, LED lighting. This jack does not have a timer function.
12. Place the solar module in a sunny, shadow-free place.
13. Ensure that the solar pump is always fully submerged in the water.
14. The SolarMax 2500 Accu fountain set is now ready for operation.
Note
The pump has a built-in dry running protection function. Two sensor points are provided
on one side of the pump body (not visible from the outside). If one or both of the sensor
points is not under the water, the pump will stop working.
Care and maintenance
Solar module
Dust, dirt and leaf deposits can build up on the solar module. You can remove these with a microfibre cloth and glass cleaner.
Solar pump
Should the pump start to lose pumping capacity or after a period of time stop working, then please clean the pump as follows.
1) Disconnect the pump cable from the solar module.
2) Unlock the top and bottom parts of the pump housing by pressing the clasps on the two opposite sides of the housing and then lift off the top part of the housing (see Figs. 1 and 2)
3) Take out the pump and open the rotor cover by turning it anticlockwise (see Fig. 3)
4) Pull out the rotor from the rotor bay (see Fig. 4)
6) Clean and wash the individual components.
7) Reassemble the pump in reverse order
Caution! During cleaning, please be careful not to damage the ceramic shaft. It can be easily broken.
Protect the pump and battery box from frost!
The pump should not be operated during the cold winter months. Clean the pump with warm water and store the whole system in a frost-free place. The battery box should ideally be
stored in a fully charged state.
