Thank you for choosing the Matala HK25LP Hakko Linear Air Pump. This manual provides essential information for the safe and efficient operation, installation, maintenance, and troubleshooting of your air pump. Please read this manual thoroughly before operating the unit and keep it for future reference.

2. Safety Instructions

Always observe the following safety precautions to prevent injury or damage to the unit:

• Electrical Safety: Ensure the power supply matches the pump's requirements (voltage, frequency). Always connect the pump to a grounded outlet. Do not operate with a damaged power cord or plug.
• Water Proximity: This pump is not submersible. Always install the pump in a dry, well-ventilated area, protected from direct rain, splashes, and flooding. The pump must be placed above the water level to prevent back-siphoning.
• Ventilation: Ensure adequate airflow around the pump to prevent overheating. Do not cover the pump or block its ventilation openings.
• Handling: Do not lift or carry the pump by its power cord.
• Maintenance: Disconnect power before performing any maintenance or cleaning. Only use genuine Hakko replacement parts.
• Children and Pets: Keep the pump out of reach of children and pets.

3. Setup

3.1 Unpacking

Carefully remove the air pump and all accessories from the packaging. Inspect the unit for any signs of damage during transit. If damage is found, contact your supplier immediately.

3.2 Placement

Select a suitable location for the air pump:

• Dry and Protected: The pump must be installed in a dry, sheltered location, away from direct sunlight, rain, and excessive dust.
• Above Water Level: Always place the pump above the highest water level of your pond or application to prevent water from siphoning back into the pump. If this is not possible, install a check valve on the air line.
• Ventilation: Ensure the area has good air circulation to prevent overheating. Maintain at least 6 inches (15 cm) of clear space around all sides of the pump.
• Stable Surface: Place the pump on a flat, stable surface to minimize vibration and noise.

3.3 Air Line Connection

Connect the appropriate size air hose (typically 3/4 inch or 1 inch) to the pump's outlet nozzle. Secure the hose with a clamp if necessary. Run the air hose to your air diffusers or air stones in the pond or application.

3.4 Electrical Connection

Plug the power cord into a properly grounded electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for outdoor or wet environments.

4. Operation

4.1 Initial Startup

Once all connections are secure and the pump is properly placed, plug in the power cord. The pump should start operating immediately, producing air from the diffusers/stones.

4.2 Continuous Operation

The Hakko HK25LP is designed for continuous operation. Monitor the air output and ensure the pump is running smoothly. Periodically check for any unusual noises or vibrations.

4.3 Air Flow Adjustment (if applicable)

If your setup includes an air manifold with individual valves, you can adjust the airflow to specific diffusers as needed. Do not restrict the overall airflow excessively, as this can put strain on the pump.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your air pump. Always disconnect power before performing any maintenance.

5.1 Air Filter Cleaning/Replacement

The air filter sponge prevents dust and debris from entering the pump. Check and clean the filter sponge every 3-6 months, or more frequently in dusty environments. To clean, remove the filter cover, take out the sponge, wash it with clean water, and allow it to dry completely before reinserting. Replace the filter sponge annually or if it shows signs of deterioration.

5.2 Diaphragm Replacement

The diaphragms are wear-and-tear components and typically need replacement every 12-18 months, depending on usage and environmental conditions. Reduced airflow or increased noise are indicators that the diaphragms may need replacement. Refer to the specific diaphragm replacement kit instructions for detailed steps. It is recommended to use genuine Hakko replacement parts.

5.3 General Cleaning

Keep the exterior of the pump clean and free of dust and debris. Use a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
