MP-129 Series Water-Saver
350545 1–7
All Models Solenoid valve 6SV, which supplies water to activate the standard ejector, is
still active in the sterilizer piping system. However, 6SV is only energized
during negative pulses and during the purge above the water-saver pres-
sure setpoint.
The cooler the water used for the ejector, the more efficiently the ejector
operates. To keep the water in the reservoir below 120°F (49°C), tempera-
ture control switch 1S controls the flow of cold water through solenoid valve
1SV.
When the water temperature rises above 115°F (46°C), temperature control
switch 1S signals solenoid valve 1SV to open, allowing cold water to enter
the reservoir and cool the stored water. Temperature control valve 1S con-
tinually monitors the water temperature within the reservoir. When the reser-
voir water cools (temperature is below 96°F [36°C]), temperature control
switch 1S outputs signals to solenoid valve 1SV and the solenoid valve
closes. This maintains the desired water temperature.
Any excess water, such as when cooling water is added to the reservoir,
drains through the overflow drain port.
When the pump motor turns on, it draws water from the bottom of the reser-
voir into the pump. The pump forces the water through the ejector and then
recirculates it to the reservoir. This creates the required vacuum.
