to 18" wide and approximately 34-1/2" high from fl oor to 
underside of the countertop.

• The dishwasher must be installed so that drain hose is no 

more than 10’ in length for proper drainage.

installer must ensure that the dishwasher is completely enclosed 

at the time of installation.

CLEARANCES: 

When

installed into a corner,
allow 2” min. clearance
between dishwasher and

other appliances. Allow
25-5/8" min. clearance

DRAIN REQUIREMENTS

• Follow local codes and ordinances.
• Do not exceed 10’ distance to drain.
• Do not connect drain lines from other devices to the 

dishwasher drain hose.

NOTE:

 Air gap must be used if waste tee or disposer connection 

is less than 18" above floor to prevent siphoning.

DETERMINE DRAIN METHOD

The type of drain installation depends on the following
questions.

  Do local codes or ordinances require an air gap?

  Do local codes or ordinances require an air gap?

  Is waste tee less than 18" above floor?

  Is waste tee less than 18" above floor?

If the answer to either question is YES, Method 1 MUST

be used.

• If the answers are NO, either method may be used. 

CABINET PREPARATION

• Drill a 1-1/2" diameter hole in the cabinet wall within 

the shaded areas shown in Figure A for the drain hose 
connection. The hole should be smooth with no sharp edges.

IMPORTANT:

 When connecting

sure that drain plug has been
