PLUMBING PREPARATION

To avoid being scalded, 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.

WARNING

Scald Hazard

Figure 6

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 inches (152.4 mm) away from the dishwasher’s base and water inlet valve.

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 bars).

Hot Water Supply Plumbing Install an easily accessible shut-off valve (not supplied) in the hot water supply line, as shown in Figure 6. All solder connections must be made before the water line is connected to the dishwasher’s water inlet valve. Water may also be supplied to the dishwasher by using a stainless steel braided hose approved for dishwasher use. Check with your local plumbing supply sources for the proper hose and 90° elbow fitting.

NOTE: Regardless of where the hot water supply line

enters the enclosure, position the line 14” (355mm) from the enclosure’s left side, as shown in Figure 6.

NOTE: Decide whether stainless steel braided hose approved for dishwasher use or copper tubing will be used for the hot water supply plumbing, and purchase the correct type of hot water supply shut-off valve, 90° elbow, and necessary fittings for the hot water supply plumbing.
