Water advice

If the tap water in your area is very hard, it is advisable to mix

the tap water with an equal amount of demineralised water.

Easy to rinse

The new design of the rinse cap makes it very easy to rinse

the boiler regularly. Simply unscrew the cap and pour out the

“dirty” water into the sink.

No hassle with coins, extra tubes or anything of this sort.

Fixed water tank

The ﬁxed water tank that is incorporated into the stand allows

re-ﬁlling anytime during ironing. Since water is not re-ﬁlled

directly into the boiler, there is no waiting time for boiler to

cool down.

- Due to the high wattage of the iron, only the specified cord set must be used.

- Should damage be observed on the HOSE-CORD ASSY or CORDSET 55, they must be replaced.

Continued usage is not allowed.

- When replacing the MICROSWITCH ASSY 9, please dress the 2 attached wires such that they are free of tension. Pulling force

on the wires may affect the steam triggering.

- To avoid damage to the sealing & components of the BOILER ASSY 38, NEVER clean the boiler assy with vinegar, descaling

agent or other corrosive chemicals.

- When replacing ELECTROVALVE 40 or PUMP ASSY 45, please be reminded to apply loctite at the joints for good sealing.

- After the product has been repaired, it should function properly and has to meet the safety requirements & legal regulations 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 that soleplate temperature is within IEC requirement.

Measure the temperature of the soleplate after the iron has reached steady state i.e connected to the mains for at least 15 minutes.

The table below shows the temperature requirement.

Marking

Soleplate temperature (Deg C)

Material, for example

Test-

point

Minimum Maximum Nominal + Tolerance

•(1 dot) 70 120 95 ± 25 Acetate, elastane, polyamide, polyproylene

•• (2 dots) 100 160 130 ± 30 Cupro, polyester, silk, triacetate, viscose, wool

••• (3 dots) 140 210 175 ± 35 Cotton, linen

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 the product during operation.

Check that the functionality of the product (product dependent) eg. steaming, variable steam, SOS, ASO etc is working properly.

4. Loose part

Check that there are no loose parts eg. extra screw in the product that can cause short-circuit or product malfunction.
