4. Installation
Proper installation is crucial for the optimal performance and longevity of your MixBubole FLO900-DS Pro pump. If you are unsure about any step, consult a qualified plumber or electrician.
4.1 Placement
- The pump is designed for compact spaces and can be installed under basins, inside cabinets, or near shower rooms and laundry areas.
- Ensure the pump is placed on a stable, level surface.
- Allow sufficient space around the unit for ventilation and future maintenance access.

4.2 Connecting Wastewater Inlets
- The pump features four Ø40mm universal wastewater inlets. Connect your sink, shower, washing machine, or other fixtures to these inlets using the provided plastic inlet hoses and hose clamps.
- Ensure all connections are tight and sealed to prevent leaks.
- Unused inlets must be securely capped with the provided plugs.
4.3 Connecting Discharge Outlets
- The pump has two discharge outlets. Connect the discharge pipe to one of these outlets. The other outlet should be capped if not used.
- The discharge pipe should have a minimum diameter of 1 inch (25mm) to 1-1/2 inches (38mm).
- Ensure the discharge pipe has a slight downward slope (at least 2%) towards the main sewer line to facilitate flow.
- The pump can lift wastewater vertically up to 39.4 feet and horizontally up to 394 feet.

4.4 Ventilation
- The pump includes an external exhaust valve to trap odors.
- If necessary, a 1/2-inch venting pipe can be connected to ensure proper air circulation and odor control.
- The installed activated carbon filter helps maintain an odor-free environment.
4.5 Electrical Connection
- Connect the pump to a grounded 110V-120V/60Hz power outlet.
- Ensure the electrical circuit is protected by a Ground Fault Circuit Interrupter (GFCI) for safety.
- The innovative switch system keeps all electrical components safely above the water, minimizing the risk of electrical leakage and short circuits.
5. Operation
The MixBubole FLO900-DS Pro pump operates automatically once properly installed and connected to power.
5.1 Automatic Activation
- The pump features a fully automatic ON/OFF mechanism. It will activate when the water level inside the unit reaches approximately 3 inches.
- The pump will continue to run until the water level drops to approximately 2 inches, at which point it will automatically shut off.

5.2 PCB Delay Function
- The integrated PCB (Printed Circuit Board) provides a time delay function. This prevents the pump from cycling too frequently, especially with minor water inflows, leading to quieter operation and energy savings.
5.3 Manual Switch
- A manual button is available for drainage if needed, typically for testing or specific maintenance procedures. Refer to the 'Product Details' diagram in the Installation section for its location.
6. Maintenance
Regular maintenance ensures the efficient and reliable operation of your pump.
6.1 Blade Agitation and Foreign Object Removal
- In case of clogging, the cover on the top of the unit can be opened to access and agitate the blades. This allows for the removal of foreign objects without requiring complete dismantling of the pump.
- Always disconnect power before opening the cover or performing any maintenance.

6.2 Activated Carbon Filter
- The activated carbon filter helps neutralize odors. Periodically check and replace the filter as needed to maintain optimal odor control.

6.3 Cleaning
- The polypropylene (PP) outer shell is resistant to aging and scratches, making it easy to clean with a damp cloth.
7. Troubleshooting
Before contacting customer service, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power, float switch stuck, motor issue. | Check power connection and circuit breaker. Ensure float switch moves freely. Contact customer service if motor issue is suspected. |
| Pump runs continuously. | Float switch stuck, check valve issue, continuous water inflow. | Check float switch for obstructions. Inspect check valve for proper function. Verify no constant water source is feeding the pump. |
| Pump is noisy. | Foreign object in macerator, pump vibrating. | Disconnect power and check macerator for foreign objects (refer to Maintenance). Ensure pump is on a stable surface. |
| Pump is leaking. | Loose connections, damaged seals. | Inspect all inlet and outlet connections and tighten hose clamps. Check for visible damage to the unit. |
| Pump is clogged. | Excessive debris, non-maceratable items. | Disconnect power. Open the top cover and agitate blades to clear debris. Remove any non-maceratable items. |
