1. Cleaning and preparation. Before starting the installation, make sure that all fittings are clean and that the original fittings on the pressure cooker lid (e.g. seals, safety valves, etc.) have been properly disassembled or removed.

2. Install the seal. Lay the new sealing ring on the bottom of the lid, make sure it fits evenly on the bottom of the lid, do not twist or pull it flat, then place the lid on the cooker and tighten the screws from top to bottom, make sure that each screw is tightened equally.

3. Install the safety valve and other valves. Insert the safety valve into the hole on the lid of the pressure cooker, screw the bonnet tightly so that it fits tightly with the mounting hole, then place the rubber gasket ring next to the safety valve on the bonnet and press gently with your fingers to make it fit solidly on the bonnet.

4. Install the handle and pressure limiting valve. Combine the handle and handle together and fix them together with screws, then put the fixed handle opposite to the hole on the lid of the pressure cooker, put the screws into the holes and screw them tightly, pick up the pressure limiting valve and then put it on the corresponding position on the lid, and then press it down firmly, and it will be installed.

5, install other accessories. Depending on the specific model and design of the pressure cooker, you may also need to install fusible links, cams, water level gauges, exhaust valves, etc. The installation of these accessories varies, but usually involves inserting the accessories into the corresponding holes and fixing them with screws or similar tools.
