Removing the Freezer Drawers

For models with two freezer drawers, remove both drawers in the same way.

The Pullout Drawer located above the freezer drawer is not shown for clarity.

WARNING

To reduce the risk of electric shock, injury to persons, and death, follow basic precautions, including the following:

••Use two or more people to remove and install the refrigerator doors and freezer drawer.

••Be careful of sharp hinges on both sides of the drawer.

••When you lay the drawer down, be careful not to damage the floor.

••Do not sit or stand on the freezer drawer.

Aligning the Doors

If the door is too low, lift the door up and screw on a door hinge bolt in the manner shown below using a spanner and a pair of long nose pliers.

Adjusting the Left Fridge Door

Open the fridge door and use the spanner to rotate the door hinge bolt as shown below.

Refitting the Doors and Drawer

Mount the doors in the reverse sequence of their removal once the appliance has been passed through all access doors.

Leveling the appliance

If the door of the appliance is not level, adjust the difference in the height of appliance door using the following method.

Open the door and use the supplied spanner to adjust the level of the lower side, using the nut on the adjustable round foot as per the below diagram.

NOTE

••Because the hinge pin may fall out, do not adjust the height of the appliance door more than 3 mm.

Adjusting the Right Fridge Door

<Type1>

If the door is too low, use the spanner to rotate the door hinge bolt as shown below.

<Type2>

If the door is too low, lift the right door up and insert use a pair of long nose pliers to insert ring sheets until both doors are level.

Connecting the Water Line

Water Supply Requirements

A cold water supply with water pressure between 138 kPa and 827 kPa (1.4-8.4 kgf/cm²) is required to operate the water dispenser. If the refrigerator is installed in an area with low water pressure (below 138 kPa), you can install a booster pump to compensate for the low pressure.

If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 138 kPa to 827 kPa (1.4-8.4 kgf/cm²)

WARNING

••Unplug the appliance before carrying out any work on connecting the water line. Failure to do so may cause electric shock.

••Only connect the water line to a cold water supply. Failure to do so may cause the water filter to malfunction. Water hammer (water banging in the pipes) in house plumbing can cause damage to appliance parts and can lead to water leakage or flooding.

••Connecting the water line must only be installed by a qualified plumber and in accordance with local legislation and regulations governing water quality.

NOTE

••This water line installation is not covered by the appliance warranty.

Connecting to the Appliance

1	Unscrew the metal threaded collar nut at
	the back of the appliance and place it over
	one end of the water tube.
2	Firmly push the water tube onto the water
	inlet valve and tighten up the collar nut.

Connecting the Appliance

After installing the appliance, connect the power plug into a socket outlet.

NOTE

••After connecting the power supply cord (or plug) to the outlet, wait 2 or 3 hours before you put food into the appliance. If you add food before the appliance has cooled completely, your food may spoil.

Checking the Water Connection

1	Turn on the water supply and switch on the
	appliance. Carefully check all fittings for
	possible leaks due to poorly fitted hoses.
2	Press and hold the Water Filter button for
	three seconds. That resets the Replacement
	Filter icon. The new water filter has been
	activated.
3	Place a cup under the water dispenser to
	verify that water is flowing through the
	appliance.
4	Check the connecting tube and joints for
	leaks once again.
5	The water filter should be fixed at a
	appropriate place where it is easy to reach

for replacement purposes.

Moving the Appliance

1	Remove all food from inside the appliance.
2	Pull the power plug out, insert and fix it into
	the power plug hook at the rear or on top of
	the appliance.
3	Tape parts such as shelves and the door
	handle to prevent from falling off while
	moving the appliance.
4	Move the appliance with more than two
	people carefully. When transporting the
	appliance over a long distance, keep the
	appliance upright.
5	After installing the appliance, connect the
	power plug into a socket out to switch on

the appliance.
