DRAIN SUPPLY (Proper installation)
Viking provides a 7/8” drain hose which is connected
to the back of the unit to form a high loop. If additional
drain hose is needed, please purchase an additional
Viking drain hose and join it to the provided hose with
a 7/8” copper tube. (Do not use any fittings anywhere
in the drain line that are less than 7/8” ID).
The access hole for the drain line should be 1 ½”.
The end of the drain line is ½”, but it is adjustable to
7/8”, ¾” 5/8”. If the drain connection is larger than ½”,
you can easily cut the drain line to fit the connection.
The illustration to the left show three different ways to
connect the drain supply line.
THE HIGH LOOP
All Viking dishwashers have drain hoses attached to the
drain pump and fastened to the back of the unit. This
gives the drain hose an automatic high loop, which is
necessary for proper draining. The drain hose is
fastened at the best loop height with a plastic zip tie.
To eliminate potential drain problems, simply leave this
hose in place.
IMPORTANT THINGS TO REMEMBER
• Failure to provide the proper drain connection
height (minimum of 20” above the bottom of the
dish washer base) lower than a 20” high loop will
result in improper drainage, which will damage
the machine.
• No part of the drain hose should be higher than
35” from the bottom of the dishwasher.
• The hose must be drawn straight to a floor well or
its equivalent because it might function as a
siphon and empty the machine.
• The drain hose can be extended to a maximum
length of 10 feet. Joints and jointed tubes, if any,
must have an ID of at least 7/8”.
• 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 the drain line.
• Don’t use fittings smaller than 7/8”, otherwise the
water may not drain properly.
