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.
Installation Preparation
• The rough cabinet opening must be at least 24”
deep. The opening should be 35” max. height.
CLEARANCES:
When installed into a corner, allow 2”
min. clearance between dishwasher

appliances. Allow 25-5/8” min. clear-
ance from the front of the dishwash-
er for door opening. Figure B

Dishwasher
Countertop
• The dishwasher must be installed so that drain hose is no more
than 10 feet in length for proper drainage.
• The dishwasher must be fully enclosed on the top, sides and
back, and must not support any part of the enclosure.
Method 1 - Air Gap with Waste Tee or Disposer
Method 2 - High Drain with Waste Tee Disposer

CABINET PREPARATION
• Drill a 1-1/2” dia. hole in the cabinet wall within the shaded
