Product Overview
Familiarize yourself with the components of your JK-300L steam iron:

- Base Plate: The heated surface that comes into contact with fabric.
- Temperature Control Knob: Used to select the desired ironing temperature for different fabric types.
- Switch: Main power on/off switch for the iron.
- Spray Switch: Activates the steam function.
- Electromagnetic Valve: Controls the release of steam.
- Power Cable: Connects the iron to the electrical outlet.
Setup
- Position the Iron: Place the iron on a stable, heat-resistant ironing board or surface. Ensure adequate space for movement and safety.
- Assemble Water System:
- Connect one end of the water hose to the water inlet on the iron.
- Connect the other end of the water hose to the gravity feed water bottle.
- Hang the water bottle above the iron, ensuring it is securely placed and the hose is not kinked. The water level in the bottle should be above the iron for proper gravity feed.
- Fill Water Bottle: Fill the gravity feed water bottle with distilled or demineralized water. Do not exceed the "MINIMUM WATER LEVEL" mark (as seen in image S640694e22c1c48f39275f23f283caf37h.jpg). Using tap water may lead to mineral buildup and damage over time.
- Connect Power: Plug the power cable into a suitable 220V-50/60Hz grounded electrical outlet.
Operating Instructions
- Power On: Flip the main power switch on the iron to the "ON" position. The indicator light (if present) should illuminate.
- Set Temperature: Turn the Temperature Control Knob to the desired setting based on the fabric type you are ironing. Refer to garment care labels for guidance. Allow the iron to heat up completely; this may take a few minutes.
- Steam Ironing:
- Ensure the water bottle is filled and properly connected.
- Once the iron reaches the set temperature (indicator light may turn off or change color), press the Spray Switch to release steam.
- Move the iron smoothly over the fabric, applying steam as needed to remove wrinkles.
- Dry Ironing: For dry ironing, simply do not press the Spray Switch.
- After Use:
- Flip the main power switch to the "OFF" position.
- Unplug the iron from the electrical outlet.
- Allow the iron to cool down completely on the iron rest before storing.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your iron.
- Cleaning the Soleplate:
- Ensure the iron is unplugged and completely cool.
- Wipe the soleplate with a damp cloth and a mild, non-abrasive cleaner. Do not use harsh scouring pads or metallic cleaners.
- For stubborn residue, specialized iron soleplate cleaners can be used following their instructions.
- Draining Water: After each use, it is recommended to empty any remaining water from the gravity feed bottle to prevent stagnation and mineral buildup.
- Storage: Store the cooled iron upright on its heel rest or the provided iron rest in a dry, safe place. Ensure the power cord is neatly wrapped and not kinked.
- Descaling (if necessary): If you notice reduced steam output or mineral deposits, descaling may be required. Consult a qualified technician or refer to general steam iron descaling procedures, using appropriate descaling solutions.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Iron does not heat up. | Not plugged in; power switch off; faulty outlet; internal fault. | Check power connection; ensure switch is ON; test outlet with another appliance; contact service. |
| No steam or insufficient steam. | Water bottle empty; temperature too low; mineral buildup; hose kinked. | Fill water bottle; increase temperature setting; descale iron; check hose for kinks. |
| Water leaks from soleplate. | Temperature too low for steam; overfilling water bottle; mineral deposits. | Allow iron to heat fully before steaming; do not overfill bottle; descale iron. |
| Iron leaves marks on fabric. | Soleplate dirty; temperature too high for fabric. | Clean soleplate; adjust temperature according to fabric type. |
If the problem persists after attempting these solutions, please contact customer support.
