Plumbing Requirements
Drain Connection
IMPORtANt:
A 72” drain hose is supplied with the product.
Should a longer drain hose be required, use a hose
approved for detergents and high temperature water. The
drain hose supplied with the dishwasher meets an AHAM
DW-1 test standard. Longer drain hoses should not be
longer than a total of 10 ft. in length.
Review the different ways shown to connects the
•
dishwasher to the drain system. Choose the method
that best suits your need and meets local codes and
ordinances.
You must install an air gap in the drain if the drain hose
•
is connected to household plumbing lower than 20 in.
(50.8 cm) from the floor or if required by local codes.
Plan for the air gap in the sink or countertop area
adjacent to the dishwasher. A section of drain hose (not
provided) needs to be installed from the air gap to the
disposal or waste tee. The drain hose is routed from
the dishwasher to an air gap inlet as shown. Air gap
kits are available from a plumbing supply store.

If an air gap is not required, the drain hose must be
•
installed to an inlet or waste tee above the drain trap in
the household plumbing. If you connect to a sink drain,
entry will need to be above the trap. Use a “Y” branch
tailpiece and connector kit (not include) for this method.
It includes all needed fittings and instructions.
Hot Water Supply
The water pressure must be between 20 and 120 p.s.i.
•
(138-827 kPa). The household hot water heater must
supply a minimum of 120 °F water to the dishwasher
location for best results.
Install a valve for the hot water supply line where it is
•
easily accessible after the dishwasher is installed.
Be sure the water inlet is protected from freezing. If the
•
valve freezes and ruptures, flooding may occur.
Determine the amount of tubing needed to connect
•
the hot water supply to the unit’s water inlet valve.
Copper tubing must have a minimum of 3/8” OD. High-
pressure and high-temperature rated plastic tubing with
a minimum inner diameter of 1/4” may be used.
