WATER SUPPLY
CONNECTION
PLUMBING THE
DISHMACHINE
CONNECTING THE
DRAIN LINE
All plumbing connections must comply with all applicable local, state, and national
plumbing codes. The plumber is responsible for ensuring that the incoming water line
is thoroughly fl ushed prior to connecting it to any component of the dishmachine. It
is necessary to remove all foreign debris from the water line that may potentially get
trapped in the valves or cause an obstruction. Any valves that are fouled as a result
of foreign matter left in the water line and any expenses resulting from this fouling are
not the responsibility of the manufacturer.
The drain for the dishmachine is a gravity-discharge drain. Remove the overfl ow
strainer stopper from the tub and the unit will drain itself. There must also be an air
gap between the machine drain line and the fl oor sink or drain. If a grease trap is
required by code, it should have a fl ow capacity of 5 gallons per minute (GPM).
Ensure that you have read the section entitled “PLUMBING THE DISHMACHINE”
above before proceeding. Install the water supply line (3/4” pipe size minimum) to the
end of the Y-strainer. It is recommended that a water shut-off valve be installed in the
water line between the main supply and the machine to allow access for service. The
water supply line is to be capable of 25 pounds per square inch (PSI) “fl ow” pressure at
the recommended temperature indicated on the data plate. In areas where the water
pressure fl uctuates or is greater than the recommended pressure, it is suggested that
a water pressure regulator be installed. The Model 10 does not come with water a
pressure regulator as standard equipment.
Do not confuse static pressure with fl ow pressure. Static pressure is the line pressure
in a “no fl ow” condition (all valves and services are closed). Flow pressure is the
pressure in the fi ll line when the fi ll valve is opened during the cycle.
It is also recommended that a shock absorber (not supplied with the dishmachine) be
installed in the incoming water line. This prevents line hammer (hydraulic shock)—
induced by the solenoid valve as it operates—from causing damage to the equipment.
Slowly turn on the water supply to the machine after the incoming fi ll line and the drain
line have been installed. Check for any leaks and repair as required. All leaks must be
repaired prior to placing the machine in operation.
Take care not to confuse
static pressure with
fl ow pressure.
