WARNING

Avoiding General Hazards

Do not use the dishwasher until it is completely installed. When opening the door on an uninstalled dishwasher, carefully open the door while supporting the rear of the unit. Failure to follow this warning can cause the dishwasher to tip over and result in serious injury.

Before installing the supplied counter top mounting brackets, decide which method will be used to secure the dishwasher into its opening. Once these mounting brackets are installed on the dishwasher, removing them is difficult and will damage the mounting brackets and the dishwasher.

In some conditions, hydrogen gas can form in a hot water system that has not been used for weeks. Hydrogen gas is explosive. Before filling a dishwasher from a system that has been off for weeks, run the water from a nearby faucet in a well ventilated area until there is no sound or evidence of gas.

Temperatures required for soldering and sweating will damage the dishwasher’s base and water inlet valve. If plumbing lines are to be soldered or sweated, keep the heat source at least 6″ (152.4 mm) away from the dishwasher.

Removing any cover or pulling the dishwasher from the cabinet can expose hot water connections, electrical power and sharp edges or points. Handle with care.

Avoiding Electrical Shock/Fire Hazards

Do not work on an energized circuit. Doing so could result in serious injury or death. Only qualified electricians should perform electrical work.

Do not attempt any work on the dishwasher electric supply circuit until you are certain the circuit is de-energized.

Make sure electrical work is properly installed. There should be no loose electrical connections. Ensure all electrical connections are properly made.

The customer has the responsibility of ensuring that the dishwasher electrical installation is in compliance with all national and local electrical codes and ordinances. The dishwasher is designed for an electrical supply of 120V, 60 Hz,AC, connected to a dishwasher-dedicated, properly grounded electrical circuit with a fuse or breaker rated for 15 amps.

Electrical supply conductors shall be a minimum #14 AWG copper only wire rated at 75°C (167°F) or higher.

2

This appliance must be connected to a grounded metal, 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. Do not use extension cords.

Avoiding Plumbing/Scalding Hazards

Do not perform any work on a charged hot water line. Serious injury could result. Only qualified plumber should perform plumbing work. Do not attempt any work on the dishwasher hot water supply plumbing until you are certain the hot water supply is shut off.

Properly tighten all water connections. Not doing so could result in a leak.

Check local plumbing codes for approved plumbing procedures and accessories. All plumbing should be done in accordance with national and local codes.

If using copper tubing or other material not depicted in this manual for water supply, defer to a licensed plumber for proper installation.

Water Inlet Connections

WARNING

Avoid Scald Hazard

Do not perform any work on a charged hot water line. Serious injury could result. Only qualified plumbers should perform plumbing work.

Do not attempt any work on the dishwasher hot water supply plumbing until you are certain the hot water supply is shut off.

CAUTION

Temperatures required for soldering and sweating will damage the dishwasher. If plumbing lines are to be soldered or sweated, keep the heat source at least 6 inches (152.4 mm) away from the dishwasher.

Hot Water Supply

The hot water heater should be set to deliver approximately 120° F (49° C) water to the dishwasher. Water that is too hot can cause some detergents to lose effectiveness. Lower water temperatures will increase run times.

The hot water supply pressure must be between 15 - 145 psi (1 - 10 bar).

IMPORTANT NOTES:

If using a solder joint instead of a compression fitting, be sure to make all solder connections before connecting the water supply line to the dishwasher.

Make sure there are no sharp bends or kinks in the water line that might restrict water flow.

Always use the appropriate seal when making plumbing connections.

Before connecting the water supply line to the dishwasher, flush the incoming water line for approximately 5 minutes to clear any foreign material.

Turn on the water supply and check for leaks after connections are made.

21

23

Connect the dishwasher water supply line to the water shut off valve.

You will need to use an approved dishwasher water supply line with the correct fittings for this connection. Always use the appropriate seal when making plumbing connections.

After all connections are made, turn on the hot water and check for leaks.

Drain Connections

IMPORTANT NOTES about your drain connection:

If local ordinance require an air gap, install it according to the manufacturer’s instructions.

If the dishwasher drain hose is to be connected to a disposer dishwasher drain connection, remove the plug from the disposer’s dishwasher drain connection.

The dishwasher drain hose must have one place along its length that is securely attached 20″ (508mm) above the cabinet floor.

The drain hose length can be extended if necessary. The maximum length of the drain hose, including the hose leading to the air gap, is

150″ (3800mm).
