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.
Air gap must be used if waste tee or disposer connection
is less than 18" above floor to prevent siphoning.
Figure C
Method 1 – Air Gap with Waste Tee or Disposer
An air gap must be used when required by local codes and ordinances.
The air gap must be installed according to manufacturer’s instructions.
The type of drain installation depends on the following
questions.
■ Do local codes or ordinances require an air gap?
■ Is waste tee less than 18" above floor?
If the answer to either question is YES, Method 1 MUST
���
����
���
����
• If the answers are NO, either method may be used.
Figure D
Method 2 – Drain Hose Routing
When not using an air gap, the drain hose must be routed to form a high
loop of at least 32" to prevent siphoning. See Step 15 on page 10.
• 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.
When connecting
drain line to disposer, check to be
sure that drain plug has been
removed. DISHWASHER WILL NOT
DRAIN IF PLUG IS LEFT IN PLACE.
������
������
����
An air gap MUST BE USED if the drain hose is connected to
waste tee or disposer lower than 18" above the floor level.
Failure to provide the proper drain connection height with an
air gap or 32" minimum high drain loop will result in improper
draining of the dishwasher, which may cause damage.

connected to an individual properly grounded branch circuit
protected by a 15 or 20 ampere circuit breaker or time delay

• Wiring must be 2 wire with ground and rated for 75°C (176°F).
• If the electrical supply does not meet the above
requirements, call a licensed electrician before proceeding.
Ground
Black
Figure E
White
For models equipped with power cord: Do not modify the plug
provided with the appliance; if it will not fit the outlet, have a
proper outlet installed by a qualified technician.
Grounding Instructions–Cable Direct
This appliance must be connected to a grounded metal,
permanent wiring system, or an equipment grounding
conductor must be run with the circuit conductors and be
connected to the equipment grounding terminal or lead on the
appliance.
Cabinet Preparation and Wire Routing
• The wiring may enter the opening from either side, rear or the
floor within the shaded area.
• Cut a 1-1/2" max. diameter hole to admit the electrical cable.
Cable direct connections may pass through the same hole
as the drain hose and hot water line, if convenient. If cabinet
wall is metal, the hole edge must be covered with a bushing.
Note: Power cords with plug must pass through a separate
hole.
Grounding Instructions–Power Cord Models
This appliance must be grounded. In the event of a malfunction
or breakdown, grounding will reduce the risk of electric shock
by providing a path of least resistance for electric current.
This appliance is equipped with a cord having an equipment
grounding conductor and a grounding plug. The plug must
be plugged into an appropriate outlet that is installed and
grounded in accordance with all local codes and ordinances.
Electrical Connection to Dishwasher
Electrical connection is on the right front of dishwasher.
• For cable direct connections the cable must be routed as
shown in Figure E. Cable must extend a minimum of 24" from
the rear wall.
• For power cord connections, install a 3-prong grounding type
receptacle in the sink cabinet rear wall, 6" min. or 18" max.
from the opening, 6" to 18" above the floor.
WARNING
The improper connection of the equipment
grounding conductor can result in electric
shock. Check with a qualified electrician or
service representative if you are in doubt that
the appliance is properly grounded. Do not
modify the plug provided with the appliance;
if it will not fit the outlet, have a proper outlet
installed by a qualified technician.

• The line may enter from either side, rear or floor within the
shaded area shown in Figure F.
Locate and set aside the package containing
2 Phillips head countertop mounting screws
and 2 additional toekick screws (located in
the literature package).
• The line may pass through the same hole as the electrical
cable and drain hose. Or, cut an additional 1-1/2" dia. hole to
accommodate the water line. If power cord with plug is used,
water line must not pass through power cord hole.
• To check the door balance, hold the top of the dishwasher
firmly.
The hot water supply line pressure must be at least 20 psi.
Lower pressures could cause the water valve to leak and
cause water damage.
• Open the door slowly. If the door drops when released, you
will need to increase spring tension. If the door closes when
released, you will need to decrease tension.
• If adjustments are needed, see Step 1A. If no adjustments are
