DRAIN REQUIREMENTS
• Follow local codes and ordinances.

• Do not connect drain lines from other devices
to the dishwasher drain hose.
• Dishwasher must be connected to waste line with an
air gap (not supplied) or 32" minimum high drain loop, depending
on local codes and ordinances to prevent back flow into the
dishwasher.
• Air gap must be used if waste tee or disposer connection is less
than 18" above the floor to prevent siphoning.
DRAIN PREPARATION
The type of drain installation depends on answers to
the following questions:
■ Do local codes or ordinances require an air gap?
■ Will waste tee or disposer connection be less than
18" above the floor?
■ Will installation have a drain loop less than 32"
above floor?
If the answer to ANY of the 3 questions above is YES,
Method 1 MUST be used. Otherwise either Method 1
or Method 2 may be used. Figure C or Figure D.
CAUTION:
An air gap MUST BE USED if the drain hose is connected to waste
tee or disposer lower than 18" above the floor.
Failure to provide the proper drain connection height with air gap or
32" minimum, high drain loop will result in improper draining of the
dishwasher.
