Connecting the Drain Hose
Before continuing with this section, be certain that your drain meets the
requirements detailed in Drain Requirements in Chapter 2: Prerequisites.
Be certain you conform to all local plumbing codes when you route and connect
the drain.
The drain hose is installed at the factory. The hose provides a flexible coupling to
the drain piping and can be secured with a spring or band hose clamp. (A band
hose clamp is provided with your washer.)
Tubing or pipe 5/8" (1.6 cm) ID or larger should be used for the drain.
Do not route the drain to an elevation more than 36" (91 cm) above the pump
discharge. Do not reduce the size of the drain plumbing.
Do not remove the hose from the clamp on the rear of the glassware washer.
The use of an air gap is strongly recommended for all installations to prevent the
siphoning of wastewater into the washer.
The drain piping can be routed to either a sink or a floor drain. If you route the
drain piping to a sink drain without using an air gap, the highest point of the drain
pipe must be above the highest water level in the sink, as shown below.
If an air gap is not
used, the drain line
must be elevated
above the water
level of the sink.
