Drain Options - Viking DFUD040 Manual

DRAIN: A drain hose 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 at a minimum of 20" from the flood.
If the hose provided is not long enough,
extend it with a 7/8" copper tube. Do
not use any fittings anywhere in the
drain line that are less than 7/8". If the
drain line is going to be connected to a
waste disposer, be sure to remove the
knock out pr plug from the fitting on the
disposer before connecting drain line. The dishwasher drain hose has a factory installed
check valve. Do not add an additional check valve.
Different ways to connect the drain line: (A) Typical drain connecting 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.
CAUTION: Failure to provide either the proper drain connection height above floor
level or a 20" 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 feet. Joints and
jointed tubes, if any must have an Inside Diameter (ID) of a least 7/8". No part of the
drain hose must have a position higher then 35" 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.
