GENERAL DESCRIPTION
Section 1 Introduction
The water-saver is an add-on system that incorporates a water ejector with
a pump and a water reservoir to recirculate the water that creates the
vacuum necessary for part of the sterilization cycle. The water-saver can
typically save 70% of the total water used during a cycle.
Compatible sterilizer models are listed in Table 1–1.

• The MP-129A can be installed on the 400/500 Series sterilizers, but the
MP129F is preferred because it does not require a pressure switch.

MP-129 Water-Saver The operation of the MP-129 Water-Saver (see Figure 1–1) is controlled by
an electromechanical pressure switch (1PS) that monitors the pressure in
the sterilizer chamber. See Theory of Operation — “MP-129 Water-Saver”

Introduction
TECHNICAL DATA
NOTE
The water-saver should not be used with a sterilizer with Sealing Flange—
for example, those installed in an area that may process Bio Hazard
material or Bio-contaminated waste. If installed in a sterilizer of this type, the
water-saver could become a breeding ground for bioburden, which would
then be constantly recirculated through the system. Additionally,
decontaminating the components would be difficult at best.
The dimensions and weight, utilities requirements, and electrical supply for
the water-saver are listed on installation drawing HS3472, included in the
water-saver package.
The capacity of the reservoir tank is approximately 6 gallons (22.7 liters).

THEORY OF OPERATION
MP-129 Water-Saver Water-saver Pressure Switch 1PS determines whether the water-saver or
the standard ejector in the sterilizer provides the vacuum. While the
pressure in the sterilizer chamber is above 1 PSIG, Pressure Switch 1PS
selects the standard ejector. But when the sterilizer chamber pressure drops
to 1 PSIG or lower, Pressure Switch 1PS instead turns on the recirculating
pump to activate the ejector in the water-saver system.

MP-129F Water-Saver Pressure values are evaluated by the sterilizer software to determine
whether the water-saver or the standard ejector in the sterilizer provides the
vacuum. The water-saver configuration dipswitch (DS14 on the sterilizer’s
DISPSWITCHES menu) must be set to 1 in order for the water-saver to
operate. While the pressure in the chamber is above -5 psig for vacuum
cycles, or above atmospheric pressure for gravity cycles, the sterilizer
software selects the standard ejector. When below these values, the
software turns on the water saver.

MP-129 Series Water-Saver
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 pressure 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), temperature 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 continually monitors the water temperature within the reservoir. When the reservoir 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 reservoir into the pump. The pump forces the water through the ejector and then
recirculates it to the reservoir. This creates the required vacuum.

BYPASS SWITCH
MP-129 The toggle switch on Water-Saver I/F Box 47A permits hospital
maintenance or Getinge USA service personnel to switch off the watersaver as a vacuum source and use the sterilizer’s standard ejector with
external water supply.

MP-129F The water-saver can be turned off from the display panel on the sterilizer.
The Water Saver configuration switch (DS14) is located on the
DIPSWITCHES branch of the SERVICE menu tree. Refer to the sterilizer
Service Manual for instructions on how to navigate the menu tree.
MANUAL DRAIN VALVE
Located in the feed water line to the pump, this manual valve permits easy
draining of the water-saver reservoir when required.

Section 2 MP-129 Installation
Follow the instructions in this user manual when installing an MP-129
Water-Saver to any of the following sterilizers:
• 100 and M/C 3500 Series (MP-129A)
• 200 and M/C 3600 Series (MP-129B)
• M/C 4233 (42") (MP-129C)
• M/C 4233 (76") (MP-129D)
CAUTION
NOTES
If you are installing a MP-129F Water-Saver to a 400/500, 700
or 800 Series sterilizer, follow the instructions in Section 3.
High-vacuum sterilizers (x33 or xx33 models) benefit most from the use of
the water-saver. However, the water-saver can be installed on any Getinge
USA sterilizer that uses a water ejector as its vacuum source.
Bills of Materials (BOMs) and drawings necessary for assembling this kit are
included with the parts.
• Use the BOMs as a checklist to verify receipt of all parts.
• Use the BOMs and the drawings to assemble the parts per these
instructions.
• Retain all BOMs and drawings with the unit for future reference
