WATER INSTALLATION
Water installation is carried out as shown in figures 3 and 4. The hot water line to the dishwasher must
provide between 20
±5
psi of water pressure. The hot water heater should be set to deliver
≥
140
°
F water
temperature to the dishwasher for best results. Use ¾” copper tubing inlet line.

CAUTION:
Do not confuse static pressure with flow pressure. Static pressure is the line pressure in a
“no flow” condition (all valves and services are closed). Flow pressure is the pressure in the fill line
when the solenoid valve is opened during the cycle
THE DISPLAY OF THE PRESSURE GAUGE SHALL BE CLEARLY VISIBLE OF THE
OPERATOR OF THE MACHINE. THE GAUGE SHALL HAVE INCREMENTS OF 1 psi (7 kpa)
OR SMALLER AND SHALL BE ACCURATE TO ±2 psi (±14 kpa) IN THE 15-25 psi (103-172 kpa)
RANGE. IF THE GAUGE IS LOCATED UPSTREAM OF THE CONTROL VALVE, IT SHALL BE
MOUNTED IN AN ACCESSIBLE VALVE WITH A ¼ IN IRON PIPE SIZE CONNECTION.
.
If the
water pressure is less than 20 psi (1.4 kg/cm
2
), installation of a water pump is required as shown
in Fig. 4. In areas where the pressure fluctuates or is greater than the recommended pressure, it is
suggested that a water pressure regulator be installed.

It is necessary to remove all foreign debris from the water line that may potentially get trapped in the
valves or cause an obstruction, prior to connecting to the machine.
Use only the supplied hoses (3/4” Female hose connector) at the water connections. Failure to do so
may result in damage to the solenoid valve threads and leaking. Tighten by hand. Connect the bent
side of the hose to the machine. Adaptor supplied for ¾” female garden hose connection.
FOR HARD WATER SUPPLIES WITH A HARDNESS OF OVER 2 GRAINS OR 10ºF AND PH
BEYOND THE RANGE OF 7.0 – 8.5, A WATER CONDITIONER MUST BE INSTALLED.
Slowly turn on the water supply to the machine after the incoming fill 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.
