SAFETY PRECAUTIONS
If the power cord is bad, to avoid risk it is required to replace it by the technicians
of our special shop or the after-sale service department. Keep the pin of the power
plug clean.
Do not share one receptacle with other
electric appliances. Do not use it in
case that the power plug is damaged
or the inserting into the receptacle is
loose.
Earth
Do not wash water-proof laundries such
as the raincoat, bicycle shelter etc. To
avoid abnormal vibration during spinning.
If the power cord is bad, to avoid risk it is required to replace it by the technicians
of our special shop or the after-sale service department. Keep the pin of the power
plug clean.
Be sure to earth the earthing wire reliably.
Do not put the machine at damp place like
the bathroom. Never wash it with water.
Do not let the machine share one receptacle
with other electric appliances. If the power
plug is damaged, or the plugging into the
receptacle is loose, do not use the plug any
more.
Do not install or store the washer where
it will be exposed to the weather.
The power cord plug should be convenient
to be pluged in or pluged out with hand
while the washing machine runs normally.
Be sure to pull the plug out and close the
water tap when the machine is idle,when
moving the machine,or when cleaning
the machine.Do not use wet hand to ins-
ert or pull out the power plug.

WARNING AND CAUTIONS
Do not decompose, repair or alter the
machine by yourself.
Do not stretch hands into the working
machine. It is dangerous even if the
rotation is slow. Take special care of
the children.
Do not put any hot or heavy items (such
as the kettle with hot water ) on the
washing machine.
The handicapped or children without
care shall not use the machine.
Under certain conditions, hydrogen gas may be produced in a hot water system that has
not been used for 2 weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot water
has not been used for such a period, before using the washing machine, turn on all hot
faucets and let the water flow from each for several minutes.
This will release any accumulated hydrogen gas. As the gas
is flammable, do not smoke or use an open flame during this time.
Keep the machine away from direct
sunlight and heat source like the heater.
Do not wash articles that have been
previously cleaned in, washed in, soaked
in, or spotted with gasoline, dry-cleaning
solvents, other flammable, or explosive
substances as they give off vapors that
could ignite or explode. Do not add
gasoline, dry-cleaning solvents, or other
flammable, or explosive substances to
the wash water. These substances give
off vapors that could ignite or explode.

1. Attach the water inlet hoses to the hot water faucet and the cold water
faucet. Using pliers, tighten the coupling. ( As figure 1)
4. Check for leaks
(1). Swing the water inlet hose gently to confirm if it is suitable.
(2). Turn on the water faucets and check for leaks. A small amount of water might
enter the washers. You will drain this later.
3. Attach the hose connected with hot water faucet to the HOT water inlet valve(sign
with "H'). Attach the hose connected with cold water faucet to the COLD water
valve(sign with C ). ( As figure 2)
NOTE: Do not over-tighten.
2. Run water through both faucets and inlet hoses, into a bucket or laundry tub, to get
rid of particles in the water lines that might clog the inlet valves screens.
Install the drain hose
First install the drain hose hook on the parts of
outer drain hose component.
Put the drain hose clamp on the outer drain hose,
insert the outer drain hose into the joint for it, and
then clutch tightly with drain hose hoop.
