4. FEATURES & TECHNICAL EXPLANATION

4-1. Product Features

If you raise the Upper Rack, you can load large dishes in the Lower Rack.(Max. 14 in.)The tall tub provides large dishes loading as well as large capacity.LG dishwashers let you load oversized items in the Lower and Upper Rack.

Newly introduced Slim Direct Inverter motor is inverter-controlled. Speed iscontrolled based on program selection. It also offers high energy efficiency tominimize energy loss.

This is one of the best performance solutions for drying dishes because itminimizes venting humid air to the outside of the dishwasher. In addition, thissystem ensures better drying results compared to the condensing dryingsystem.

Because of alternating water spray between the Upper and LowerRack, the water pressure allows superior performance and reducedconsumption of water and electricity.

For best wash results, the self-cleaning filter system continuously cleans thewater as it circulates. Your LG dishwasher has a self-cleaning filter that grindsfood into small particles before it goes down the drain.

9. INSTALLATION INSTRUCTION

Step 1: PREPARE CUPBOARD OPENING

1. This dishwasher is designed to fit a standard dishwasher opening as shown below.

2. Select a location as close to sink as possible for easy connections to water and drain lines.

3. The dishwasher should not be installed more than 10 ft. (3m) from the sink for properdrainage.

4. If dishwasher is to be installed in a corner, a minimum of 2 in. (50mm) is required betweenthe dishwasher and an adjacent a wall.

Ensure the floor under the dishwasher is at the same level as the rest of the room to

allow for any service requirements.

If dishwasher will sit directly onsubflooring, subfloor should besealed with a waterproof paint orsealer to prevent damage fromsteam.

Drill a 1-1/2 (38mm) dia hole or cutout for drain hose, inlet hose andelectrical cables on either side.

approx. 4 (100mm, W) X 4 (100mm, H)

These openings must be within 4(100mm) from the floor and 1-5/8(40mm) from the back wall. If there isa floor in the cabinet under the sink,it will also be necessary to drill or cutthrough the floor to connect thewater and drain under the sink.

- 43 -- 43 -

WARNINGFor personal safety, remove house fuse or open circuit breaker before installation. Do not use an extension cord or adapter plug with this dishwasher.Electrical and grounding connections must comply with the national electricalcode/provincial and municipal code and/or other local codes.

Figure A

Step 2: PREPARE THE ELECTRICAL WIRING

1. This appliance must be operated with correct voltage as shown in this manual and on therating plate, and connected to an individual, properly grounded branch circuit, protectedby time delay fuse. Wiring must be 3 wires including ground.

2. The wiring or cord should be in an accessible location adjacent to, and not behind thedishwasher and within 4 ft. (1.2m) of the dishwasher side.

3. The wiring or cord must be grounded properly, if in doubt, have it checked by a qualifiedelectrician. No other appliance shall be connected to the same outlet by a double adapteror similar plug.

4. The wiring or cord must be oriented as shown in Figure A below.

5. Check the dishwasher for any damage before trying to install it.

6. Make sure water line and Electrical line are oriented in the bottom channels as shown inthe figure below.If you find any damage to the dishwasher, Please contact your dealer or builderimmediately.

- 44 -- 44 -

Step 3: PREPARE THE WATER SUPPLY CONNECTION

1. This dishwasher may be connected to either hot or cold water. If the water can not bemaintained below 149 (65 ), the dishwasher must be connected to cold water.

2. When connecting the dishwasher water line, sealing tape or compound should be used toavoid leaks.

3. When connecting the dishwasher water line, the house supply should be shut off.

4. The Water Supply Tube must be oriented as shown in Figure A on page 6.

Step 4: PREPARE DISHWASHER FOR INSTALLATION

1. Adjust the legs to the required height to fit properly under the countertop as shown below.

2. Check the level of dishwasher by using level.

■■ Left side – turn theadjusting screwcounterclockwise to lowerthe leg and raise the rearof the dishwasher.

■■ Right side – turn theadjusting screw clockwiseto lower the leg and raisethe rear of the dishwasher.

■■ Front feet can be adjustedfrom the top using a 1/4〃square drive wrench.

- 45 -- 45 -

1. Remove the Lower Cover and orient dishwasher as shown below.

2. Before sliding the dishwasher into the cupboard opening, make all necessary heightadjustments using the legs.

3. Slide the dishwasher into the cabinet opening carefully. Make sure that the drain hoseinside the cabinet is not kinked.

4. Follow the instruction as in Figure B.

Step 5: INSTALL THE DISHWASHER IN CUPBOARD

- 46 -- 46 -

Step 6: DRAIN LINE CONNECTION

1. If the end of the drain hose does not fit to the drain line, use an adapter (not supplied) thatmust be resistant to heat and detergent and may be obtained from a plumbing shop.

2. There are 2 typical connections as shown in Figures C & D.

There may be other options than shown here for connection the drain hose. The drainconnection must meet local plumbing regulations.

The S trap spigot must be drilled out cleanly and free of obstruction to its maximuminternal diameter, if used for drainage.

To prevent syphoning, one of the following instruction methods must be followed:

Follow local codes and ordinances.

Do not exceed 10 ft. (3m) distanceto drain.

Do not connect drain lines fromother devices to the dishwasherdrain hose.

NOTE: It is not recommended to modify this part – replace part if installingnew drying system on semi model.

Appendix. C※ If it is necessary to retrofit an earlier model with the new drying system,

please follow the instructions below for modifying or replacing parts.

1) Remove front door panel & control panel.2) Remove old blower & vent.3) Cut the door liner white felt pad as shown*. Scissors work best for cutting the

felt. (See Appendix C for part number if felt is to be replaced.)*NOTE: The white felt can be marked with a felt pen using the new vent as a template.

Cut out areas as shownfor blower clearance

4) Assemble and m ount the new blower & vent.5) The control panel frame must be modified or replaced. If it is to be modified for

blower clearance, cut out areas shown in the photos below*. Test fit panel todoor liner prior to assembly to make sure panel does not touch blower motoror housing as this could cause excess noise.

*NOTE: It is not recommended to modify the semi- control panel or front door panel. Retrofit ofthe new drying system to LDS5811xx models s hould only be done by replacing the frontdoor panel and control panel. ( see Appendix C for parts)
