CONNECTING THE
DRAIN LINE
The manufacturer recommends the installation of a pressure regulating valve (PRV)
in the incoming water line to ensure proper owrate at all times and oers these
devices as options (see the Plumbing Options page).
Do not confuse static pressure with ow pressure. Static pressure is the line pressure
in a “no ow” condition (all valves and services are closed). Flow pressure is the
pressure in the ll line when the ll valve is opened during the cycle.
The manufacturer also recommends the installation of a shock absorber in the
incoming water line and oers these devices as options (see the Plumbing Options
page). This prevents line hammer/hydraulic shock—induced by the solenoid valve as
it operates—from causing damage to the equipment.
The machine's drain is a gravity-discharge drain. All piping from the 1 1/2” NPT
connection on the wash tank must be pitched (1/4” per foot) to the oor or sink drain.
All piping from the machine to the drain must be a minimum 1 1/2” NPT and must not
be reduced. There must also be an air-gap between the machine drain line and the
oor sink or drain. If a grease trap is required by code, it should have a ow capacity
of 5 GPM.
