GROUNDING INSTRUCTIONS
For a permanently connected appliance:
This appliance must be connected to grounded metal, a permanent wiring system, or an
equipment-grounding conductor must be run with the circuit conductors and connected to
the equipment-grounding terminal or lead on the appliance.
The dishwasher is very heavy. Do not attempt to move or carry a dishwasher alone. Two or
more people are needed to move a dishwasher and avoid potential injuries.
Ifthe power cable is damaged, it must be replaced by the manufacturer, a service agent or
similarly qualified person in order to avoid a hazard.
Do not touch the power cable with wet hands.
Do not connect another appliance to the same power outlet as the dishwasher.
Make sure to use a new water supply line. Old lines are susceptible to breakage because
they become hardened and may cause property damage due to a water leakage.
Ifthe temperature of the water supplied to the dishwasher is higher than 149 °F(65 °C),
control the heater so that it drops below 149 °F(65 °C). If it does not drop below 149 °F
(65 °C),connect the water supply line to a cold water supply.
Ensure that the water supplied to the dishwasher does not freeze. Frozen water can
damage the hoses, valves, pump, or other components.

2. Ensure that the water supply valve is turned off before connecting the water supply line to the
dishwasher.
3. Seal the water supply line connections using teflon tape or sealing compound to stop any
water leakage.
4. The water supply line should be placed in the channels at the base of the dishwasher as
shown in Figure 2. Do not place the dishwasher on the water supply line.
5. The drain hose connected to the dishwasher must be run through the hole in the side wall so
it can be connected to the drain outlet of the sink. Ensure that there is nothing on the drain
hose and be careful not to tear it during the installation process.

STEP 8 SECURING THE DISHWASHER
The dishwasher should be fixed to the countertop or side walls for additional stability and safety.
1. When the countertop is made of wood or the material will not be damaged by drilling, follow
the instructions in 2-1 below.
When the countertop is made of granite, marble or any other kind of material that can be
damaged by drilling, follow the instructions in 2-2 below.
2-1. Check to connect the Installation brackets to the front top of the dishwasher as shown in
Figure 8. (If the Brackets are exposed under the countertop, cut them using a tool as shown
in Figure 8. Be careful that you are not hurt by the cutting plane.)
Attach the dishwasher to the countertop by fastening the screw through the hole.
2-2. Open the door and remove the tub spacer caps on both sides of the tub. Insert the screws
into both sides of the tub except for the tub spacer cap and secure the dishwasher to the
side walls by fastening them as shown in Figure 9. At this time, fasten the screws and ensure
that the tub is not distorted.
After fastening the screws, place the tub spacer caps into original location of the dishwasher.
The screws or tub spacer cap may fall into the dishwasher while you are working
with the door open. Cover the interior of the dishwasher with a towel to prevent any
screws from falling into the dishwasher. If any foreign items such as a screw get into
the dishwasher, it may cause noise, an abnormal operation, damage, or a product
malfunction.
Use a magnetic screwdriver to help prevent screws from falling into the dishwasher.
If a foreign item such as a screw gets into the dishwasher and you are unable to remove
it, it needs to be disassembled. Contact a qualified service technician for this.

3. Check the size of the sink's drain hose connector. Ifneeded, cut the drain hose so its end
fits into the sink connector (1/2 in., 3/4 in. or 1 in. - as shown in the Figure below). Ifthe
end of the drain hose does not fit into the drain hose connector of the sink, use an adaptor
purchasable at a plumbing/hardware supply store.
4. When connecting the drain hose, make sure to fasten it using a hose clamp. Failing to do so
may cause water leakage.
5. If there is no air gap, make sure to hang the middle of the drain hose in a high location to
prevent backflow (see the figure below).
ABe careful when cutting off the end of the drain hose as there is a risk of injury. Clean
....... around the sink's drain connection so that it does not damage the hose. Check for any
foreign items in the drain hose and remove them.
