A rubber drain hose (7/8” [2.2 cm]) is provided with the dishwasher which is connected to the back of the unit to form a
high loop. The access hole for the drain line should be 1 1/2” (3.8 cm) at a minimum of 20” (50.8 cm) from the floor. If
the hose provided is not long enough, extend it with a 7/8” (2.2 cm) copper tube. Do not use any fittings anywhere in
the drain line that are less than 7/8” (2.2 cm) ID. If the drain line is going to be connected to a waste disposer, be sure
to remove the knockout or plug from the fitting on the disposer before connecting drain line. The dishwasher drain
hose has a factory installed check valve.

o Not
add an additional check valve. NOTE: The end of the drain hose is
1/2” (1.3 cm), but is adjustable to 7/8” (2.2 cm), 3/4” (1.9 cm), or 5/8” (1.6 cm). If the drain connection is larger than
1/2” (1.3 cm), the hose can be cut to fit the connection.
Different ways to connect the drain line:
A. Typical drain connections to sink plumbing before trap (high loop drain).
B. Connection to an air gap, then to the trap.
C. Connection to a waste disposer with air gap.
DRAIN
CAUTION: Failure to provide either the proper drain connection height (20” [50.8 cm] above floor level) or a 20”
(50.8 cm) high loop will result in improper draining of the dishwasher, which will cause damage to the dishwasher.
NOTE: The drainage hose can be extended to a maximum length of 10 ft. (3 meters). Joints and jointed tubes, if
any, must have an ID of at least 7/8” (2.2 cm). No part of the drain hose must have a position higher than 35” (88.9
cm) above the floor. The hose must not be drawn straight to a floor well or its equivalent. The hose might then
function as a siphon-emptying the dishwasher. When the installation is ready, open the supply valve and let the
pressure become equalized. Then check that all connections are tight and there are no leaks. The drain hose is
attached to the drain pump and fastened to the back of the unit. The drain hose is fastened to the back of the unit at
the best high loop height. To eliminate potential drain problems, leave this hose in place.
