Drain Hose
The dishwasher comes with a seven (7) foot drain hose.
•A 1.25” access hole must be made to allow the drain hose to be run to the drain connection location.
CAUTION
To protect against possible rupture of the fill valve, water lines leading to the dishwasher, as well as water lines in the dishwasher MUST be protected against freezing. If the valve or water line freezes, flooding may occur. Such ruptures are not covered by the warranty.
Hot Water Supply
•The hot water line to the dishwasher must provide between 5 - 120 psi (0.3- 8.27 bars) water pressure.
•The hot water heater should be set to deliver 140°F (60°C) water temperature to the dishwasher.¹
•A 3/8” minimum O.D. copper tubing inlet line is recommended.
•All solder connections must be made before water line is connected to the dishwasher’s inlet water valve. Do not solder within 6 inches (152.4 mm) of the dishwasher’s inlet water valve.
•Drill a 1” (25.4 mm) diameter access hole in the cabinet for the water supply line (Figure 9A).
•Run the line to the approximate fill valve location, as shown in Figure 9A.
It is recommended that a

If no air gap is used and the drain line is run into a sink or disposer, the drain line must be elevated to a point higher than the highest water level of the sink to prevent back siphoning into the dishwasher.
NOTE: If connection to an air gap is required by local code, air gap kits are available from local plumbing sources. Install the air gap according to the manufacturer’s instructions.
