Setup and Installation
Installation of the WinZo WZ5311-P system requires basic plumbing and electrical knowledge. If you are not confident in your abilities, it is recommended to hire a qualified professional.
1. Site Preparation
- Choose a suitable location for the toilet system. Ensure there is adequate space for the unit and access for maintenance.
- Verify that a grounded 110V-120V/60Hz electrical outlet is available within reach of the pump's power cord.
- Plan the discharge pipe routing to the main sewer line. The pump can handle vertical lifts up to 26 feet and horizontal runs up to 262 feet.
2. Connecting the Macerator Pump
The macerator pump is designed to connect to the toilet and can also accept waste from up to three additional sanitary devices (e.g., bathroom sink, shower, laundry, kitchen sink).

- Connect the toilet outlet to the designated inlet on the macerator pump using the provided connectors and clamps.
- If connecting additional fixtures, use appropriate plumbing fittings to connect their waste lines to the available inlets on the pump. Ensure all connections are sealed properly.
- Connect the discharge pipe from the pump to your main sewer line. Install a non-return valve on the discharge pipe to prevent backflow.
3. Water Supply Connection
- Connect the toilet's water supply line to a cold water source using a flexible connector. Ensure the connection is tight to prevent leaks.
- Slowly turn on the water supply and check for any leaks at all connection points.
4. Electrical Connection
- Plug the macerator pump's power cord into the grounded electrical outlet.
- The system is now ready for initial testing.
Operating Instructions
The WinZo WZ5311-P features a dual flush system for water efficiency.
Dual Flush Operation
- The toilet is equipped with a dual flush button located on the right side of the tank.
- Press the smaller button for a 1.1 GPF (Gallons Per Flush) flush, suitable for liquid waste, to conserve water.
- Press the larger button for a 1.6 GPF flush, suitable for solid waste, ensuring powerful and efficient removal.
Upon flushing, the macerator pump will automatically activate to grind and pump the waste to the main sewer line. The pump operates quietly and efficiently.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your WinZo macerating toilet system.
Cleaning the Toilet
- The skirted design and high-quality porcelain make the toilet easy to clean. Use mild, non-abrasive bathroom cleaners and a soft cloth or sponge.
- Avoid using harsh chemicals, bleach, or abrasive pads, as these can damage the porcelain finish and the soft-close seat.
- For the soft-close seat, clean with mild soap and water. Do not use strong chemical cleaners.
Macerator Pump Care
- Do Not Flush Inappropriate Items: To prevent clogs and damage to the macerator blades, never flush items such as sanitary products, wet wipes, paper towels, dental floss, or excessive amounts of toilet paper.
- Regular Inspection: Periodically check the pump and connections for any signs of leaks or unusual noises.
- Descaling (if necessary): In areas with hard water, mineral deposits may accumulate. Consult a plumbing professional for descaling procedures if you notice reduced pump performance.
