1. WHAT IS DRUM ?

1. WHAT IS DRUM WASHER?

One of the famous washers in the globe which uses laundry falling energy.

2. Sales point of our washer

◈ The biggest capacity with compact size

◈ No damage and entanglement but excellent washability

◈ 4way savings-noise, vibration, washing times, energy

◈ Self-cleaning course of Drum

◈ Good washing performance with heating system

◈ Condensing dry system with saving energy

◈ Big door glass with easy laundry take-in/out

◈ The higest spin speed

1) Deciding the water level

① Normal, Cotton, Whites course will be followed by this process.

② Check the water level with dry laundry at the starting wash.

③ Check the water level by using motor output data during 10 sec, 75 rpm.

2) Balancer Spin

① Check after finishing washing step with wet laundry.

② Checking by using motor output data during 10 sec, 75 rpm.

③ The decided data is different depending on loading condition.

2 -2 LA NC E S N

1) Motor running during balance spin.

① Spreading the laundry : Rotating the same 45 rpm with left and right direction alternatively.

② Attaching stop : Attaching the laundry to drum inside with constant speed.

③ Unbalance checking point : First step, check the U.B at 95 rpm, 160 rpm.

Second step, check the U.B at 95 rpm, 350 rpm.

Third step, at 300 rpm. if the unbalance data is over the criterion,

This process will be repeated.

④ Drain step : Drain at water around 160 rpm.

⑤ After drain, check the unbalance data again. This is so-called balance spin step.

2) Property of balance spin.

① Conducting 10 times maximum.

② If the washer can not pass balance spin step during 10 times, then water will be supplied.

③ If the washer can not pass 20 times of balance spin, UE error mode will be displayed on PCB.

③ After door locking, all parts can work normally.

④ After pressing power button, if the temperature of wash thermistor is over 55℃ or the water level is over the safety level, the door will be locked.

⑥ The door the will be unlocked immediately after all processes are finished.

⑦ The door can be opened during processing if there is no problem to unlock.
