INSTALLATION
GARBAGE WITH AN AIR
DISPOSAL
• A Air gap
• B Drain hose
• C Hose clamp
3) Check the size of the sink drain hose connector. If
needed, cut the drain hose so its end fits onto the sink
connector (5/8", 3/4". or 1". - as shown in Fig. 18 ). If the
end of the drain hose does not fit onto the drain hose
connector of the sink, use an adapter purchasable at a
plumbing/hardware supply store.
If necessary, cut off the dotted line of the drain hose to fit
the size.
4) Slide a hose clamp over the end of the drain hose.
Attach the drain hose to the sink connector, slide the
hose clamp to the end of the hose, and then tighten the
hose clamp.
NOTE
You must use a hose clamp. Failure to do
so may cause water leakage.
Use a hose clamp as shown in Fig. 19 for assembling the
drain hose to the sink.

5) If there is no air gap, make sure to suspend the middle of
the drain hose well above the sink cabinet base to
prevent back flow (see Fig. 20 ).

6) When drilling a hole for the drain hose on the cabinet
wall, make sure the drain hose is not damaged by the
Fig. 18
sharp edges of the hole. On wooden walls, sand the hole
to soften the edges. On metal walls, use insulation tape
or duct tape to cover the sharp edges around the hole.
7) Take care not to damage the drain hose when installing
the dishwasher on the floor, wall, or cabinet. To prevent
leaks or drainage problems, make sure the drain hose is
not damaged, kinked, or twisted.
8) Do not cut the wrinkled area of the drain hose to fit the
size. When arranging the drain hose, make sure not to
touch the sharp edges of the cabinet or under-sink.
• Be careful when cutting off the end of the drain hose as
there is a risk of injury. Clean around the sink drain
