3. Components and Parts
Familiarize yourself with the main components of your LONDAFISH Pond Feeder:
- Control Panel: Located inside the lid for easy access to programming buttons and LCD display.
- Feeder Container (Hopper): The main compartment for storing fish feed. It has a built-in baffle that can be adjusted based on feed size.
- Discharge Port: Where the feed is ejected from the storage box.
- Battery Compartment: Located at the bottom of the unit, requiring four C-type alkaline batteries (not supplied).
- Solar Panel: Integrated on top for charging the internal battery (if applicable) or supplementing power.

4. Setup
- Battery Installation: Open the battery compartment at the bottom of the feeder. Insert four new C-type alkaline batteries, ensuring correct polarity. Close the compartment securely.
- Fill the Hopper: Open the lid of the feeder and fill the hopper with dry pellet fish feed. This feeder is designed for pellet feed up to 5mm in diameter. Do not use sticks or flake food as they may cause blockages.
- Placement: Place the feeder on a stable surface at the edge of your pond or quarantine tank. Ensure the discharge port is positioned to allow feed to disperse into the water. For optimal solar charging, place the feeder where the solar panel receives direct sunlight for several hours a day. Avoid locations with prolonged direct sunlight if the unit is prone to overheating in extreme heat.
- Secure Mounting: Ensure the feeder is securely mounted or placed to prevent it from being dislodged by wind or animals.

5. Operating Instructions
The feeder allows for precise programming of local time and feeding schedules.

5.1. Programming Local Time:
- Press the 'SET' button. The hours display will blink.
- Press the '+' button to set the correct hour.
- Press the 'SET' button again. The minutes display will blink.
- Press the '+' button to set the correct minutes.
5.2. Programming Feeding Time:
The feeder supports up to 4 feeding times per day.
- Press the 'FEED' button. The LCD will display '1---'. This indicates you are entering Program Feeding Time 1.
- Press the 'SET' button. The hours display will blink.
- Press the '+' button to set the desired feeding hour.
- Press the 'SET' button again. The minutes display will blink.
- Press the '+' button to set the desired feeding minutes.
- After setting Feeding Time 1, press the 'FEED' button sequentially to cycle through and program Feeding Times 2, 3, and 4. The procedure for setting subsequent feeding times is the same as for Feeding Time 1.
5.3. Adjusting Dispensing Amount:
The feeder has a dial control for adjusting the amount of feed dispensed per feeding. Refer to the included feeding guide for recommended amounts based on your fish species and pond size. Adjust the dial to increase or decrease the quantity.
5.4. Cancelling a Programmed Feeding:
If you wish to cancel a specific programmed feeding time, navigate to that feeding time (e.g., '1---') using the 'FEED' button, then press the '+' button until '----' appears on the LCD for that specific feeding time.
6. Maintenance
- Cleaning: Regularly clean the feeder, especially the hopper and discharge port, to prevent feed buildup and blockages. The manufacturer recommends hand washing. Ensure the unit is completely dry before refilling with feed.
- Battery Check: Check the battery level periodically. Replace all four C-type alkaline batteries when the power is low or if the feeder's performance declines. Do not use rechargeable batteries, as they may not provide sufficient power. A single set of batteries typically lasts about 3 months.
- Feed Inspection: Ensure the feed used is dry and free of moisture to prevent clumping and blockages. Only use pellet feed up to 5mm in diameter.
- Environmental Check: Periodically inspect the feeder's placement to ensure it remains stable and free from obstructions. Clear any debris from the solar panel to ensure efficient charging.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Feeder not dispensing food. | Low batteries; Feed blockage; Incorrect programming. | Replace all four C-type batteries. Clean the discharge port and hopper for any clogs. Re-check programming steps carefully. |
| Feed dispenses all at once or too much. | Incorrect dispensing amount setting; Programming error. | Verify the dial control for feed amount is set correctly. Double-check all programmed feeding times and ensure no accidental continuous feeding is set. |
| Timer not working or inconsistent feeding. | Low batteries; Programming error; Internal electronics issue. | Replace batteries. Re-program the local time and feeding schedules from scratch, following instructions precisely. If issues persist, contact customer support. |
| Feeder falls over or is dislodged. | Insecure placement; Strong winds. | Ensure the feeder is placed on a very stable, level surface. Consider securing it with additional weights or a more robust mounting solution if in a windy area. |
| Unit overheats in sunlight. | Prolonged direct exposure to intense sunlight. | Relocate the feeder to a shaded area or provide some form of overhead cover to protect it from direct, intense sunlight, especially during peak heat hours. |
| Pests (e.g., mice) accessing feed. | Feeder accessible to pests. | Ensure the feeder is placed out of reach of common pests. While designed to be rat-proof, determined animals may find ways. Consider elevated placement. |
