3. Setup
3.1 Unpacking
Carefully remove the dosing pump and all accessories from the packaging. Inspect the unit for any signs of damage. Retain the packaging for future transport or storage.
3.2 Component Identification
- Dosing Pump Unit (DP-2)
- AC Power Adapter
- (Dosing tubing is not included and must be purchased separately.)
3.3 Initial Placement
Place the dosing pump on a stable, dry surface. Ensure it is positioned above the liquid reservoirs to prevent siphoning and below the aquarium water level if dosing directly into the tank. Avoid placing the unit in direct sunlight or areas with high humidity.
3.4 Power Connection
- Connect the AC power adapter to the dosing pump's power input port.
- Plug the power adapter into a suitable electrical outlet (110V-240V, 50/60Hz).
- The unit will power on, and the display will illuminate.
3.5 Tubing Installation
Dosing tubing is not supplied with the unit. Acquire appropriate aquarium-grade dosing tubing (e.g., silicone or PVC). Cut the tubing to the required lengths for your setup.
- Connect one end of the tubing to the inlet port of each pump head (P1 and P2). Ensure a secure fit.
- Place the other end of the inlet tubing into your liquid supplement reservoirs.
- Connect tubing to the outlet port of each pump head.
- Route the outlet tubing to your aquarium, securing it to prevent accidental displacement. Ensure the tubing ends are above the water level to prevent back-siphoning when the pump is off, or use check valves.
3.6 Calibration
Accurate calibration is crucial for precise dosing. A 100ml graduated cylinder or measuring cup (not included) is required for this step.
- Fill a graduated cylinder with 100ml of the liquid you intend to dose.
- Place the inlet tubing into the liquid in the cylinder and the outlet tubing into a waste container.
- Access the calibration menu on the pump (refer to the "Operation" section for navigation).
- Initiate a calibration cycle for the desired pump (P1 or P2). The pump will run for a set period.
- Measure the actual volume dispensed. Adjust the calibration setting on the pump until the dispensed volume matches the target (e.g., 100ml).
- Repeat for the second pump head.
4. Operation
4.1 Control Panel Overview
The control panel features an LCD display and several buttons for navigation and programming. Familiarize yourself with the button functions:
- Up/Down Arrows: Navigate through menu options and adjust values.
- Left/Right Arrows: Move cursor or select different parameters.
- Enter/Set Button: Confirm selections or enter programming mode.
- ESC Button: Exit current menu or cancel an action.
4.2 Programming Dosing Schedules
The DP-2 allows for highly customizable dosing schedules for each pump.
- From the main screen, press the Enter button to access the main menu.
- Navigate to the "Program" or "Setting" option using the Up/Down arrows and press Enter.
- Select the pump you wish to program (P1 or P2).
- Set the current time and date if prompted.
- For each dosing event (up to 24 per day):
- Set the desired time for the dose.
- Set the volume to be dispensed (1ml to 9999ml).
- Set the frequency (e.g., daily, every other day). Note: Some models may interpret '0' as daily and '1' as every other day. Consult the on-screen prompts.
- Save your settings before exiting the programming menu.
- Repeat the process for the second pump if needed.
Note: It is recommended to start with small dosing volumes and gradually increase as needed, monitoring your aquarium parameters closely.
4.3 Manual Dosing
The pump may offer a manual dosing function for testing or immediate dispensing. Refer to the on-screen menu for this option, typically found under a "Manual" or "Test" setting.
5. Maintenance
5.1 Routine Cleaning
Regular cleaning helps ensure optimal performance and extends the life of your dosing pump.
- Wipe the exterior of the unit with a damp cloth. Avoid using harsh chemicals.
- Periodically check tubing for blockages, kinks, or algae buildup.
- If dosing solutions are prone to crystallization, flush the tubing with distilled water regularly.
5.2 Pump Head Inspection
Inspect the peristaltic pump heads for wear and tear. The rollers and tubing inside the pump head are consumable parts and will require replacement over time.
5.3 Tubing Replacement
Dosing tubing can harden or become brittle over time, affecting dosing accuracy. Replace tubing as needed, typically every 6-12 months depending on usage and solution type.
