2. Important Safety Information
WARNING: Failure to follow these safety instructions may result in serious injury or property damage.
- Always ensure the lid is properly sealed before applying heat.
- Never force the lid open while the cooker is under pressure. Allow pressure to release completely before attempting to open.
- Do not fill the pressure cooker more than 1/2 full when cooking foods that expand during cooking, such as chickpeas, beans, grains, or dried vegetables. For other foods, do not exceed 2/3 full.
- Never use your pressure cooker for deep-frying.
- Regularly inspect the gasket and all valves for wear or damage. Replace components as needed.
- Keep hands and face away from the steam vent during operation and pressure release.
- Ensure the pressure cooker is stable on the stovetop during use.

3. Components Overview
Your Universal Pressure Cooker is equipped with the following key components:
- Pot Body: The main aluminum vessel.
- Inner Lid: Designed for secure sealing from within the pot.
- Main Steam Regulator Valve: Located on top of the lid, it maintains pressure levels and releases excessive pressure, producing a characteristic whistling sound when optimal pressure is reached.
- Auxiliary Safety Valves (2): Rubber and metallic plugs that activate to release pressure if the main valve becomes blocked.
- Practi-Press System: A manual pressure release mechanism integrated into the lid handle.
- Pivot System: Allows for precise lid adjustment and secure locking.
- Ready-to-Cook Indicator System: Provides visual confirmation when the cooker is pressurized.
- Heat-Resistant Handles: For safe handling of the pot and lid.

4. Setup and First Use
4.1 Initial Cleaning
Before first use, wash all parts of the pressure cooker (pot body, lid, gasket, and valves) with warm, soapy water. Rinse thoroughly and dry completely.
4.2 Assembling the Lid
Ensure the rubber gasket is correctly seated around the inner rim of the lid. The main steam regulator valve and auxiliary safety valves should be securely in place.
5. Operating Instructions
5.1 Filling the Pressure Cooker
Add your ingredients and liquid to the pot. Observe the maximum fill lines:
- For foods that expand (e.g., beans, rice, chickpeas): Do not fill more than 1/2 full.
- For other foods: Do not fill more than 2/3 full.

5.2 Closing the Lid
To securely close the inner lid:
- Align the arrow on the lid with the body handle.
- Tilt the lid slightly and slide it into the pot.
- Turn the lid handle until it aligns with the pot's handle.
- Place the lid handle onto the pivot point on the pot's handle.
- Squeeze the lid and body handles together firmly.
- Push the locking loop to secure the handles, ensuring a tight seal.

5.3 Heating and Pressure Building
Place the pressure cooker on a suitable stovetop (gas, electric, or glass-ceramic). Note: Not suitable for induction cooktops. Heat on high until the main steam regulator valve begins to whistle, indicating that optimal pressure (11.60 PSI / 80 kPa) has been reached. Reduce heat to maintain a steady whistle or steam release.

5.4 Pressure Release
There are two primary methods for releasing pressure:
- Natural Release: Remove the pressure cooker from heat and allow it to cool down naturally. Pressure will gradually decrease, and the ready-to-cook indicator will drop. This method is ideal for foods that benefit from continued cooking.
- Quick Release (Practi-Press System): For faster pressure release, manually activate the Practi-Press system by pressing the designated lever on the lid handle. Direct steam away from your face and hands. Use this method for foods that require precise cooking times.
5.5 Opening the Lid
Only open the lid once all pressure has been released and the ready-to-cook indicator has dropped. To open:
- Press both handles to release the hook from the body handle.
- Take the handle of the lid with one hand and the handle of the body with the other.
- Turn the lid 90 degrees until the arrow marked on the lid points to the handle body.
- When the lid handle is horizontal, slightly tilt the lid down.
- Remove the lid.

6. Maintenance and Cleaning
6.1 Cleaning After Each Use
After each use, allow the pressure cooker to cool completely. Disassemble the lid components (gasket, valves) and wash all parts with warm, soapy water. Use a soft brush or sponge to clean the pot body and lid. Ensure all food particles are removed from the valves and steam vent. Rinse thoroughly and dry immediately to prevent water spots and corrosion.
6.2 Dishwasher Safety
The Universal Pressure Cooker is dishwasher safe. However, hand washing is recommended for the lid components to ensure thorough cleaning of the valves and gasket, which can prolong their lifespan.
6.3 Gasket and Valve Inspection
Regularly inspect the rubber gasket for cracks, hardening, or any signs of wear. A worn gasket can prevent proper sealing and pressure buildup. Also, check the main and auxiliary valves for any blockages or damage. Replace any worn or damaged parts with genuine Universal replacement parts.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pressure not building or escaping excessively | Lid not properly sealed; gasket worn or misplaced; valves blocked. | Ensure lid is correctly closed and locked. Check gasket for proper placement and condition. Clean all valves. |
| Lid difficult to open after pressure release | Residual pressure; food particles obstructing mechanism. | Ensure all pressure is released (indicator dropped). Check for food debris around the lid mechanism and clean if necessary. |
| Whistling sound is inconsistent or absent | Insufficient liquid; valve blockage; low heat. | Ensure adequate liquid is in the pot. Clean the main steam regulator valve. Increase heat if necessary. |
