Preparing for Installation
Preparing the Drain
CAUtION
Keep the factory installed high loop drain hose in
place to ensure proper dishwasher operation. Do
not modify or move the mounting bracket in any
manner. If it is necessary to lengthen the hose,
install an aftermarket drain extension kit, available
at most home improvement stores.
IMPORtANt: Should a drain hose longer than the
one provided be required, use a hose extension
approved for detergents and high temperature water.
The drain hose supplied with the dishwasher meets
an AHAM DW-1 test standard. Total drain hose length
(including factory installed hose) must not exceed
10 feet. (304.8 cm) from the top of the drain loop on
the back of the unit. Joints and joint tubes must have
a minimum inside diameter of 7/8” (2.2 cm).
• The drain hose supplied with the dishwasher
must be connected to a minimum 1/2” inside
diameter drain connection.

Waste tee Installation with Air Gap
• The drain hose is equipped
with a cone-shaped connector
on the end that is ready to
be cut to the desired drain connection size. Only
a clamp (not provided) is required. It fits drain
connections with an internal diameter of 1/2, 5/8,
3/4 and 7/8 inches (1.3, 1.6, 1.8 and 2.2 cm).
• You must install an air gap in the drain system
if required by local codes. Plan for the air
gap in the sink or countertop area adjacent to
the dishwasher. A section of drain hose (not
provided) needs to be installed from the air gap
to the waste disposer inlet or waste tee.
• If an air gap is not required, the drain hose must
be installed to a disposer inlet or waste tee above
the sink trap in the household plumbing.
• For proper drainage, the drain line connection
must be a minimum of 20” (50.8 cm) above the
bottom of the dishwasher.
• No part of the drain hose can be lower than the
disposer or waste tee connection or higher than
35” (88.9 cm) from the bottom of the dishwasher.
