KitchenAid KUD-22 Serie Instructions D'installation page 7

To prevent heat damage to the fill valve, ALL solder connections must be made BEFORE the water line
is connected to the dishwasher.
.
DRAIN LINE
The drain line should be 9/,6" (14 mm) ID (minimum) flexible hose or 5,'~" (16 mm) OD copper tubing. Flexible
hose must be resistant to heat and detergent and may be obtained from a plumbing, hardware, or automotive
supply outlet. DO NOT use any fittings anywhere in the drain line that are less than
l/2"
(13 mm) ID. The
access hole for the drain line should be 1' (25 mm).
If drain line is copper, clamp a 12" (305 mm) length of g/ 16" (14 mm) ID flexible hose (heat and detergent
resistant) to the end of the copper tubing. This will facilitate connection of the drain line to dishwasher check valve.
If the drain line is going to be connected to a food waste disposer, BE SURE to remove the knockout or plug
from the fitting on the disposer before connecting drain line. Rubber adapter fitting may be required.
(KitchenAid part number 115739 or available from local hardware or plumbing stores.)

local code) IS shown in

IF DRAIN IS ROUTED TO A CONNECTION POINT LESS THAN 20" (508 mm) ABOVE THE FLOOR,
THE DRAIN LINE MUST BE MADE TO FORM A HIGH LOOP TUBE (SHOWN IN FIG. 7).
FAILURE TO PROVIDE EITHER THE PROPER DRAIN CONNECTION HEIGHT (20" (508 mm) ABOVE
FLOOR LEVEL) OR A 20" (508 mm) HIGH LOOP WILL RESULT IN IMPROPER DRAINING OF THE
MACHINE WHICH MAY CAUSE DAMAGE TO THE MACHINE.
TO FORM THE HIGH LOOP TUBE, SEE INSET ON FIG. 7. MAKE SURE THAT NO KINKS DEVELOP
IN THE HOSE OR COPPER TUBING.
