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.
2.6 WATER DRAINAGE
Attach the drain hose as shown in Fig. 5. It is recommended to affix a siphon pipe to prevent odors.
All piping from the machine to the drain must be a minimum 1-1/2” I.P.S. There should also be an air
gap between the machine drain line and the drain. For natural overflow efficiency use floor drain.
