Setup and Installation
Proper installation is crucial for the optimal performance of your bidet seat. Follow these steps carefully.
1. Pre-Installation Steps
- Remove Existing Toilet Seat: Carefully detach your current toilet seat and thoroughly clean the toilet bowl and surrounding area.
- Turn Off Water Supply: Locate the shutoff valve on the wall behind your toilet and turn it clockwise to stop the water flow.
- Flush Toilet: Hold down the flush handle until the toilet tank is completely drained of water.
- Disconnect Water Line: Unscrew the flexible water supply line from the fill valve beneath the toilet tank. Have a small bucket or towel ready to catch any residual water.
2. Installing the T-Valve
- Insert Rubber Washer: Place the provided rubber washer into the T-valve, ensuring the raised lip faces upwards.
- Connect T-Valve: Connect the T-valve to the fill valve located under the toilet tank.
- Reconnect Supply Line: Reconnect the flexible water supply line to the bottom of the T-valve.
3. Mounting the Bidet Seat
- Place Mounting Plate: Position the mounting plate over the bolt holes on your toilet, with the arrow pointing towards the toilet tank.
- Insert Brackets and Bolts: Place the adjustable brackets inside the mounting plate, aligning them with the toilet seat bolt holes. Slide the mounting bolts through the mounting plate and the holes in the toilet.
- Secure Bolts: Secure the bolts with the provided washers and nuts. Keep them loose enough to allow for seat position adjustment later.
- Position Swash Seat: Place your Swash bidet seat flat onto the toilet, in front of the mounting plate.
- Slide into Place: Slide the bidet seat towards the tank onto the mounting plate until it clicks securely into place.
- Adjust and Tighten: Adjust the seat position for the best fit, then tighten the nuts under the toilet to secure it.
4. Electrical Connection
- Turn On Water Supply: Slowly turn on the water supply at the shutoff valve and check for any leaks.
- Plug In: If there are no leaks, plug the Swash bidet seat into the nearest Ground Fault Circuit Interrupter (GFCI) outlet. The bidet will immediately power on, and the nozzle will extend and retract as part of its self-test.
