Preparing Cabinet Opening
This dishwasher is designed to fit a standard
dishwasher opening. An opening may be needed
on both sides to route plumbing and electrical
connections.
• To ensure proper drainage, install the
dishwasher no more than 12 ft. (3.65 m) from
the sink.
• The location must have sufficient space for the
dishwasher door to open easily and provide at
least 0.1” (2 mm) between the dishwasher and
the cabinet sides.
• If installing the dishwasher in a corner, leave a
minimum of 2” (50 mm) between the dishwasher
and the adjacent wall.
• The adjacent wall must be free of obstructions.
• For flush installations only, you may remove the
cabinet brace
a inside the cabinet.
Side View
For easiest installation, see marked areas a for
water and electrical clearances in base of
dishwasher. Water supply hose, drain hose and
electric cable should be passed through this area.
Choosing the Proper Location
1 Select a location as close to the sink as
possible for easy connections to water supply
line, drain hose and electrical connection.
2 To allow for proper clearance of plumbing
and electrical, use the template included with
the literature to determine the clearance on
the side of the cabinet where the cabinet
meets the back wall. Using a 2 1/2” diameter
hole saw, drill a hole in the target area as
shown on the template.

warranty, and leaks caused by improper
installation may result in property damage.
• Do not use existing holes unless they are in the
target area.
• Failure to properly locate the hole for the water
and drain lines may prevent the dishwasher
from installing flush with the cabinets and could
result in kinked, pinched, crushed, stressed or
damaged lines.
- Do not use an extension cable or adapter with
this dishwasher.
- Do not overload the outlet with more than one
appliance.

used on compression fittings.
• Connect the dishwasher to a hot water supply
with a temperature range between 120 °F (49 ℃)
and 149 °F (65 ℃). This temperature range
provides the best washing results and shortest
cycle time. To prevent damage to dishes, the
temperature should not exceed 149 °F (65 ℃).
• Water supply pressure must be between 20 psi
and 80 psi (140–550 kPa). If the water supply
pressure exceeds 80 psi, a pressure reducing
valve must be installed. Otherwise premature
failure of the inlet valve may occur.
