4. Setup and Installation
The GROHE PureGuard 3920800H bidet is designed for wall mounting. Proper installation is crucial for stability and functionality. It is strongly recommended that a qualified plumber performs the installation.
4.1 Pre-Installation Steps
- Turn off Water Supply: Locate the main water shut-off valve for your home or the specific bathroom and turn it off.
- Prepare Wall: Ensure the wall where the bidet will be mounted is structurally sound and reinforced to support the bidet's weight. An in-wall carrier system is typically required for wall-mounted fixtures.
- Review Dimensions: Carefully review the technical drawing below for precise measurements and mounting hole locations.
4.2 Mounting the Bidet
- Mark Mounting Points: Using the provided mounting set and the technical drawing, accurately mark the drilling points on the wall for the bidet and the water supply/drain connections.
- Drill Holes: Drill holes at the marked locations according to the size specified in the mounting instructions.
- Install Mounting Frame/Bolts: Secure the mounting frame or bolts into the wall as per the mounting set instructions. Ensure they are level and firmly anchored.
- Connect Plumbing: Connect the water supply lines and the drain pipe to the bidet. Ensure all connections are tight and leak-free.
- Mount Bidet: Carefully lift the bidet and slide it onto the mounting bolts. Secure it in place using the washers and nuts provided in the mounting set. Do not overtighten, as this can crack the ceramic.
- Seal Edges: Apply a bead of silicone sealant around the edges where the bidet meets the wall to prevent water ingress and provide a finished look.
