TOTO Manual Bidet Seat Usage Instructions

How to adjust the wash mode

• Push the valve up → Rear wash mode (after bowel movements)

• Push the valve down → Front wash mode (only available on E4)

⚠️ Important notes:

• Push the valve slowly

• Push it further in → stronger water pressure

• Do not open the valve suddenly to avoid discomfort

Water Pressure Requirements When Using a TOTO Manual Bidet Seat

Manual bidet seats do not have a booster pump, therefore:

• They should only be used in areas with high water pressure

• Recommended water pressure: > 0.7 kgf/cm²

👉 If the water pressure is weak, consider a Washlet electronic bidet seat
