Inlet Water Connections 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. 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. 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. Connecting the Hot Water Supply There are two plastic corrugated hoses that exit the back of the dishwasher. The larger hose, with the brass fitting on the end, is the water supply hose to the dishwasher (the other hose is the dishwasher drain hose). You will need a 3″ x 13/4″ (76 x 45 mm) opening through the cabinet to pass the dishwasher water supply line through toward the shut off valve. Figure 6     
    
 To connect the hot water supply: 1. Assemble the water supply adaptor fitting (H) from the parts bag onto the dishwasher water supply hose. This connection does not require Teflon brand tape. 2. Pass the dishwasher water supply line with attached adaptor through the opening toward the water shut off valve. Take care not to allow the hose to kink or twist behind the dishwasher. 3. Connect the dishwasher water supply line with adaptor 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. NOTE: The end of the dishwasher water inlet hose is heavy and will need to be supported. It is best to lay the end on the cabinet floor as shown in Figure 6. 4. After all connections are made, turn on the hot water and check for leaks. Water Supply Shut Off Valve Install an easily accessible shut-off valve (not supplied) in the hot water supply line, as shown in Figure 9. All solder connections must be made before the water line is connected to the dishwasher. 9 9
