• Due to the high wattage of the iron, only the specified cord set must be used.
• Should damage be observed on the POWER CORD 23, it must be replaced.
Continued usage is not allowed.
• If STAND BOTTOM 12 is provided without type plate information eg. Type number, voltage etc. When replacing the cover,
engrave the type number & voltage on the type plate with a sharp object.
• After the product has been repaired, it should function properly and has to meet the safety requirements & legal regulation
as laid down & officially established at this moment.
• The following tests are common checks that are conducted on a repaired product before it is returned to the consumer.
1. Soleplate temperature
Check the soleplate temperature is within IEC requirement.
Soleplate temperature (Deg C)
Minimum
120
2. Leakage current
Check that leakage current is within IEC requirement.
Measure leakage current between LIVE/NEUTRAL & EARTH.
IEC requirement is that at 230 V supply, the EARTH leakage current must be less than 0.75 mA.
3. Water leakage / Functionality
Check that there is no water leakage from any part of product during operation.
Check that the functionality of the product (product dependent) eg. Steaming, steam trigger, variable steam, SOS, PCBA
etc is working properly.

Self-Check mode is facilitated by a built-in diagnosis program, which tests and activates all hardware inputs and
outputs sequentially, with the aid of testing personnel's interaction and observation.
Self-Check mode is NOT an exhaustive diagnosis, but a quick preliminary check on all the hardware function.
Further test and troubleshooting may still be required to identify the root cause.
8.2. Before start Self-Check mode, please do the following checking
1. Make sure Soleplate is cold (< 100 °C)
2. Power meter in place to monitor system power
