Prepare the site and plumbing connections: Clear the installation area, ensure the floor is level, and check that plumbing and drainage pipes are ready. Install the floor flange and wax ring: Secure the flange over the drain pipe, then place a wax ring on it to create a watertight seal between the toilet pan and the drainage system. Set and secure the Indian toilet pan: Carefully lower the toilet pan onto the flange, align bolt holes, and tighten bolts evenly to fix the pan firmly to the floor without cracking it. Connect the water supply and install the cistern (if applicable): Attach the water tank to the pan, connect the water supply line using flexible hoses and Teflon tape, and check for leaks. Seal joints and test the toilet: Use cement or mortar to seal gaps around the pan and trap to prevent leakage, then flush and check for proper drainage and water tightness
