1. Warning and precautions for safety
Please observe the following safety precautions in order to use safely and correctly the
refrigerator and to prevent accident and danger during repair.
1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more
than three minutes before replacing PCB parts. Shut off the power whenever replacing
and repairing electric components.
2. When connecting power cord, please wait for more than five minutes after power cord
was disconnected from the wall outlet.
3. Please check if the power plug is pressed down by the refrigerator against the wall. If
the power plug was damaged, it may cause fire or electric shock.
4. If the wall outlet is over loaded, it may cause fire. Please use its own individual
electrical outlet for the refrigerator.
5. Please make sure the outlet is properly earthed, particularly in wet or damp area.
6. Use standard electrical components when replacing them.
7. Make sure the hook is correctly engaged. Remove dust and foreign materials from the
housing and connecting parts.
8. Do not fray, damage, machine, heavily bend, pull out or twist the power cord.
9. Please check the evidence of moisture intrusion in the electrical components. Replace
the parts or mask it with insulation tapes if moisture intrusion was confirmed.
10. Do not touch the ice maker with hands or tools to confirm the operation of geared
motor.
11. Do not let the customers repair, disassemble and reconstruct the refrigerator for
themselves. It may cause accident, electric shock, or fire.
12. Do not store flammable materials such as ether, benzene, alcohol, chemicals, gas, or
medicine in the refrigerator.
13. Do not put flower vase, cup, cosmetics, chemicals, etc., or container with full of water
on the top of the refrigerator.
14. Do not put glass bottles with full of water into the freezer. The contents shall freeze
and break the glass bottles.
15. When you scrap the refrigerator, please disconnect the door gasket first and scrap it

4.2 Using the appliance
●
This section tells you how to use most of the useful features. We recommend that you read
through them carefully before using the appliance.
Getting cold water
The water dispenser is located in the left side of fridge room. Open the refrigerator doors,
and push the water dispenser button to get water,. Then move your glass down the
dispenser lever in the suggested position and press it.
Hold the glass underneath the dispenser for 2~3 seconds after releasing the dispenser
button. Water may continue to dispense after the button is released.
Water clouding phenomenon
●
All water provided to the refrigerator flows through the filter which is an alkaline water filter.
In the filtering process, the pressure of the water that has flowed out of the filter is increased,
and the water becomes saturated with oxygen and nitrogen. When this water flows out into
the air, the pressure plummets and the oxygen and nitrogen get supersaturated, which
results in gas bubbles. The water may temporarily look misty or cloudy due to these oxygen
bubbles. After a few seconds, the water will look clear.
.
1. Changing the water filter
To drink the freshest and cleanest water from your refrigerator, change the filter on time.
To change the water filter, follow these steps:
1. Shut off the water supply. Then turn out the water filter (A) about 1/4 turn, counter-
clockwise.

11
Hisense Refrigerator
2. Pull the water
●filter (A) from the filter holder (B).
Note:
To change the water filter more
●easily, shut off the water supply valve.
Sometimes, it is hard to disassemble the water filter because impurities in the water cause
it to stick. If you are having difficulties, grip the water filter firmly and pull it out.
When you pull the water filter, a little water can leak from the opening. This is normal. To
minimize the water leaks, keep the filter cartridge horizontal when pull it.
To prevent overflow, empty the water filter tray (C) and dry around the filter case.
You should re-install the water filter tray before inserting the new filter followed the
direction below.
3. Insert the new filter into the filter holder.
4. Push the filter, and then turn it clockwise until it locks.
If you have trouble inserting the water filter because of high water pressure, shut off the

12
Hisense Refrigerator
water supply valve.
5. If you turned off the water supply, turn it back on.
Removing any residual matter inside the water supply line after installing the water
●
filter
1.Turn on the main water supply and supply water from water supply line.
2.After the water filter is replaced, dispense 2.5 gallons of water (flush for approximately 5
minutes) to remove trapped air and contaminants from the system.
3. Additional flushing may be required in some households.
4. Open the refrigerator door and make sure there are no water leaks coming from the
water filter.
Note:
Be sure to flush the dispenser thoroughly, otherwise water may drip from the dispenser.
This means that there is still air in the line.
Do not dispense the entire 2.5 gallon amount continuously. Depress and release the
dispenser pad for cycles of 30 seconds ON and 60 seconds OFF.
Reverse osmosis water supply important:
The pressure of the water supply coming out of a reverse osmosis system going to the
water inlet valve of the refrigerator needs to be between 30 and 125 psi (207 and 862
kPa).If a reverse osmosis water system is connected to your cold water supply, the water
pressure to the reverse osmosis system needs to be a minimum of 40 to 60
●psi (276 to
414 kPa).If the water pressure to the reverse osmosis system is less than 40 to 60 psi (276
to 414 kPa):
Check to see whether the sediment filter in the reverse osmosis system is blocked.
Replace the filter if necessary.
Allow the storage tank on the reverse osmosis system to refill after heavy usage.
If your refrigerator has a water filter, it may further reduce the water press when used in
conjunction with a reverse osmosis system. Remove the water filter.
2. Using your fridge compartment
The refrigerator compartment is suitable for storage of vegetables and fruit. Food inside
should be packed to store in order to avoid losing moisture or flavor permeating into other
foods.
Caution! Never close the refrigerator door while the shelves, crisper and/or telescopic
slides are extended. It may damage both them and the refrigerator.

The refrigerator compartment is provided with six same door baskets, which are suitable
for the storage of canned liquid,
bottled drink sand packed food.
To remove the door baskets, simply lift the racks up and pull straight out.
To relocate the door baskets, slide it in above the desired location and push down until it
stops.

it up vertically (2).Pull the shelf out.
To re-install the glass shelves, tilt the front of the shelf up and guide the shelf hooks into
the slots at a desired height (1). Then lower the front of the shelf so that the hooks can
drop into the slots (2).
Vegetable and fruit crispers
The crispers are suitable for storage of vegetable and fruit. To take them out, open the door
to the final location first.
Then pull out the draw and tilt up the front of the crisper after moving slightly in the directing
of the arrow.
