Do you have a question about the Whirlpool DU1055XTV and is the answer not in the manual?

Overview

This document provides installation and usage information for Whirlpool Undercounter Dishwashers, covering various models including DU1055XTV, DU1100XTP, DU1101XTP, DU1145XTP, DU1148XTP, GU2275XTV, GU2300XTV, GU2475XTV, and GU2800XTV. It outlines the necessary electrical, water, and drain requirements for proper installation and operation, ensuring the dishwasher functions efficiently and safely within a home environment. The manual also details crucial cabinet cutout dimensions and clearances to facilitate a smooth installation process.

Electrical Requirements

The dishwasher requires a 120-volt, 60-Hz, AC-only electrical supply, protected by a 15- or 20-amp time-delay fuse or circuit breaker. It is essential to use copper wiring exclusively for the electrical connection. A separate circuit for the dishwasher is highly recommended to prevent overloading other household circuits.

For direct wiring, flexible, armored, or non-metallic, sheathed copper wire with a grounding wire must be used. This wiring must comply with all local codes and ordinances, as well as the specific wiring requirements for your home. A U.L.-listed or CSA-approved conduit connector is necessary to ensure a secure and compliant connection.

If connecting the dishwasher with a power supply cord, it is imperative to use a Power Supply Cord Kit (Part No. 4317824) specifically marked for use with dishwashers. The kit includes detailed instructions for proper installation, which must be followed meticulously. The power supply cord must plug into a grounded three-prong outlet. This outlet should be located in the cabinet adjacent to the dishwasher opening and must also meet all local codes and ordinances to ensure safety and compliance.

Water Supply Requirements

The dishwasher necessitates a hot water line with a pressure range of 20 to 120 psi (138 to 862 kPa). The water temperature at the dishwasher inlet must be 120°F (49°C) for optimal performance. For the water supply connection, 3/8" O.D. copper tubing with a compression fitting is recommended. While flexible braided water supply lines can be used, 1/2" minimum plastic tubing is not advised.

A 90° elbow with 3/8" N.P.T. external pipe threads on one end is required for the connection. It is crucial not to solder any connections within 6" (15.2 cm) of the water inlet valve to prevent damage from heat. Adhering to these specifications ensures a reliable and safe water supply to the dishwasher.

Drain Requirements

A new drain hose is provided with your dishwasher. If this hose is not long enough for your specific installation, a new drain hose with a maximum length of 12' (3.7 m) (Part No. 3385556) can be used. This replacement hose must meet current AHAM/IAPMO test standards, be resistant to heat and detergent, and fit the 1" (2.5 cm) drain connector of the dishwasher.

The drain hose must be connected to a waste tee or disposer inlet located above the drain trap in the house plumbing. This connection point must be a minimum of 20" (50.8 cm) above the floor. To prevent backflow and ensure proper drainage, it is recommended that the drain hose either be looped up and securely fastened to the underside of the counter, or connected to an air gap.

If the drain hose is connected to house plumbing lower than 20" (50.8 cm) above the subfloor or floor, an air gap must be used. The air gap ensures that wastewater does not siphon back into the dishwasher, maintaining hygiene and preventing contamination. For drain line fittings, a 1/2" (1.3 cm) minimum I.D. is required. If an air gap is necessary, it should be installed according to its specific installation instructions. When connecting the air gap, a rubber hose (not provided) will be needed to connect it to the waste tee or disposer unit.

Cabinet Cutout Dimensions

Accurate cabinet cutout dimensions are essential for a proper dishwasher installation. Corner locations require a 2" (5.1 cm) minimum clearance between the side of the dishwasher door and the adjacent wall or cabinet. This clearance ensures that the door can open and close freely without obstruction.

The shaded areas on the cabinet walls in the diagrams indicate where utility connections, such as electrical and plumbing, may be installed. It is important to check that all surfaces within the cabinet cutout have no protrusions that would prevent the dishwasher from being installed correctly. The minimum height from the lowest point on the underside of the countertop is 34" (86.4 cm). This height can be reduced to 33-7/8" (86 cm) by removing the wheels from the dishwasher, if necessary. The minimum width of the opening, measured from the narrowest point, is 24" (61 cm).

The overall product dimensions are 25-1/4" (64.1 cm) in depth, 24-1/2" (62.2 cm) in width, and 33-7/8" (86 cm) in height with wheels removed. The depth from the back to the front of the door is 23-7/8" (60.6 cm), and the depth of the base is 21" (53.3 cm). There is also a 3/4" (1.9 cm) dimension indicated, which refers to insulation that may be compressed and is not used on all models.

For utility connections within the cabinet, specific clearances are provided. A clear area of 6-1/4" (15.9 cm) in height and 10-1/2" (26.7 cm) in width is designated for utility access. The distance from the back wall to the utility access area is 1-3/4" (4.4 cm). The height from the floor to the bottom of the utility access area is 3" (7.6 cm), and the height of the utility access area itself is 4" (10.2 cm). These dimensions ensure adequate space for routing electrical wires and plumbing lines without interference.
