Chapter 3 Matters needing attention
3-1. Safety
BEFORE SWITCHING THE APPLIANCE ON FOR THE FIRST TIME
DO ...
... Make sure that the transportation bolt(T1,T2&T3) are
removed.
... Use a separate earthed socket for the power supply.
... Make sure that the plug is accessible.
... Hold the plug and not the electric cable when
unplugging the power supply.
... Make sure that the fuses in the power circuit are rated
for 13A.
... Keep away from heat sources and direct sun light to
prevent plastic and rubber components from aging.
... Make sure that the power cord is not caught under or
in the appliance and avoid damage to the power cable.
... Check that hose joints and connections are firm and no
water can leak. If joints are loose or there is leakage,
turn off the water supply and refix. Do not use the
washing machine until the hoses are properly fixed.
１２
DO NOT ...
... Touch or use the appliance when barefoot or with wet or
damp hands or feet.
... Use flammable detergent or dry cleaning agent.
... Use any flammable sprays in close vicinity to the
appliance.
... Remove or insert the plug in the presence of flammable
gas.
... Allow children or infirm persons to play with the appliance
or packing materials.
... Install the appliance outdoors in a damp place, or in an
area which may be prone to water leaks such as under or
n
ear a sink unit. In the event of a water leak allow the
machine to dry naturally.
... Place the washing machine directly on a carpet, or close to
a wall or furniture.

SERVICE MANUAL
HW70-1202D HW60-1202D
HW60-1002D HW50-1202D
DURING DAILY USE OF THE APPLIANCE
DO ...
... Pull up zips and fix loose threads to prevent the items
from being entangled. If necessary, put small items into
a net bag or pillow.
... Turn off the machine after each wash program and switch
it off at the mains to save electricity and for safety. Wipe
clean the lower part of the porthole.
... Keep the door slightly open when the washing machine is
not in use to prevent formation of odours.
... Let the power cord be replaced by the manufacturer, his
service agent or other accordingly qualified persons, in
case it is damaged.
... Ensure that the appliance is not used by
persons(including children) with reduced physical,
sensory or mental capabilities, lack of experience
and knowledge without supervision or instruction by a
person responsible
for their safety.
... Supervise children to ensure that they do not play with the appliance.
13
DO NOT ...
... Touch the washer door during the washing process - it
gets hot!
... Place heavy objects or sources of heat or damp on top of
the appliance.
... Hot wash foam rubber or sponge-like materials.
... Open the detergent distribution drawer during the wash
cycle.
... Force the washer door open. The door is fitted with a
self-lock device and will open shortly after the washing
procedure is ended.
... Open the washer door if the water level is visibly over the
porthole.
... Cover the washing machine with plastic cover so that
inside dampness cannot be kept in.

_Touch this button lightly, the washing machine will start operation after a
period of time
and the corresponding indicator will go on. The range is 0.5-24 hours; each
touch of this
button increases a half hour. After the button is set, press the Start/Pause

Compartment 1: Prewash detergent
Compartment 2: Detergent for programs 1 to 10.
Compartment 3: Softener, conditioning agent, perfume, etc.
here.
Note: After power is switched on, the display will go on and the remaining
wash time decreases. As the water pressure and temperature may differ,
the remaining time maybe adjusted accordingly. When the laundry is not
balanced during spinning, the time may be automatically prolonged. These
are normal phenomena.
_If the laundry is heavily soiled, press this button before starting the
program. When the button is pressed, the washing time increases.
J ¬ Extra rinse
