Setup and Installation
Professional installation is recommended. Ensure all local plumbing codes are followed. The toilet is shipped in two separate boxes (bowl and tank). Verify all components are present before starting.
- Preparation: Turn off the water supply to the bathroom. Remove the old toilet if applicable and clean the flange area. Ensure the 10-inch rough-in measurement from the finished wall to the center of the floor drain is accurate.
- Install Floor Bolts: Secure the floor fixing bolts to the flange.
- Install Wax Ring: Place the wax ring around the horn of the toilet bowl.
- Set the Bowl: Carefully lower the toilet bowl onto the floor bolts, ensuring it is level and the wax ring creates a seal. Tighten the nuts onto the floor bolts evenly, but do not overtighten to avoid cracking the porcelain.
- Assemble Tank Components: Install the flush valve, fill valve, and tank screws into the toilet tank according to the included diagrams.
- Attach Tank to Bowl: Place the tank onto the bowl, aligning the tank screws with the holes in the bowl. Securely tighten the tank bolts, ensuring a watertight seal between the tank and bowl.
- Connect Water Supply: Connect the water supply line to the fill valve on the tank.
- Install Toilet Seat: Attach the soft-closing toilet seat using the provided seat bolts.
- Test: Turn on the water supply and check for leaks. Flush the toilet multiple times to ensure proper operation.
Operating Instructions
The WinZo WZ5088DS toilet features a dual flush system for water conservation.
- Partial Flush: For liquid waste, press the smaller button on the top of the tank lid. This uses less water.
- Full Flush: For solid waste, press the larger button on the top of the tank lid. This uses the full volume of water for a powerful flush.

Troubleshooting
If you encounter issues with your WinZo WZ5088DS toilet, refer to the following common troubleshooting steps:
- Toilet Leaks:
- Around the base: Ensure floor bolts are tightened evenly. Check the wax ring for proper seal.
- Between tank and bowl: Ensure tank bolts are tightened evenly and the tank-to-bowl gasket is properly seated.
- From water supply line: Check connections and ensure the supply line is securely tightened.
- Weak Flush:
- Check water level in the tank. It should be at the fill line.
- Ensure the flush valve flapper/seal is operating correctly and not obstructed.
- Inspect the rim jets under the bowl rim for clogs and clean if necessary.
- Toilet Runs Continuously:
- Check the fill valve for proper adjustment; the water level should not be too high.
- Ensure the flush valve flapper/seal is seating correctly and not worn or obstructed.
- Tank and Bowl Alignment Issues:
- During installation, ensure the tank is carefully aligned with the bowl's mounting holes before tightening. Slight adjustments may be needed to achieve proper fit. Verify that the rough-in measurement is precisely 10 inches from the finished wall to the center of the floor flange.
