1.0 THEORY OF OPERATION
This system is designed to pretreat and purify water for use in health care applications. Below
is the sequence of the water progression as it goes thru the components of the MOBILE SPD
SYSTEM. Each component’s theory of operation is listed in order of water progression thru
the system.
RO:
The process of osmosis can be reversed by placing pressure upon the feed water side
(concentrated solution side) of the membrane. Water will be forced through the membrane
barrier to yield water that is purer on the lower pressure side of the membrane than on the
more concentrated solution side (higher pressure side) of the membrane. The feed water will
become more “concentrated,” and will be discharged through the reject port known as “reject
water” or “concentrate”. Liberation of purer water from its solutions is caused by the reversal
of the osmotic pressure; (the operation termed as “Reverse Osmosis”). Reverse Osmosis is
commonly referred to as “RO”.
DI:
Mixed Bed De-ionizer contains both the cation and anion resins in a single vessel. The
purpose of mixing the resins is to achieve a very high quality deionized water. As water
passes through the mixed bed, it has millions of chances to contact a cation resin bead, then
an anion, then another cation, another anion, and so on. An exchange takes place, of course,
only when a positive ion contacts a negative exchange site, and vice versa. With each
exchange, purity of the water improves because more ions are removed and held by resin
beads. Mixed bed deionizer is utilized as a polishing unit downstream of the RO.
STORAGE TANK:
The reverse osmosis unit makes a limited amount of water at a time. It is therefore necessary
to store it in a storage tank. The storage tank is equipped with float switches, which will turn
the reverse osmosis unit off and on when the water reaches a predetermined point in the
storage tank.
This tank is also equipped with a spray nozzle on the return loop side of the tank. This allows
disinfectant to reach all parts of the tank when it is applied to the tank, for faster disinfections.
The vent filter on the tank is designed to filter the air when water moves in and out of the
storage tank. Tanks are equipped with a “rupture disk”, which will break if the flow of air/water
becomes too much for the filter or tank to handle.
The storage tank is equipped with 2 float switches, which will turn the
reverse osmosis unit off when the water reaches the predetermined cutoff point and
turn the RO on when the tank is drained to the appropriate level float. The
distribution pump on the storage tank will cycle whenever there is a pressure drop
detected.

2 098-0003 Rev. B
ENDOTOXIN FILTER:
The Endotoxin-Retentive Filters are the final purification process prior to distribution of the
product water. They are sub-micron filters with the ability to remove bacteria and endotoxin.
The filters are enclosed in an opaque housing to inhibit the proliferation of algae. Water flows
through the filter, which traps bacteria and endotoxin.

2.0 SYSTEM INSTALLATION
CAUTION: Local plumbing and electrical codes must be observed.
2.1 SRO
1. The electrical source for the S100 controller must be a single phase, 3-conductor
receptacle with a ground fault interrupter (GFI) at 120V, 20amp, and 60Hz. The
proper polarity and ground integrity must be initially checked and thereafter
maintained. Failure to do so may result in electrical shock to the operator. The SRO
must only be plugged directly into a GFI receptacle. It must not be plugged into an
extension cord or power strip that could cause low amperage.
To avoid electrical shock, always unplug and disconnect the SRO system
power source before opening the back of the electrical controller.
2. Mount the SRO (level) on a wall near a drain that can handle the reject water flow. (It
is recommended to secure the frame to the wall with anchoring bolts.)
3. SRO is equipped with sediment and chlorine removal.
4. Connect the feed water supply to the inlet 1/2” fitting on the SRO prefilter.
5. The feed water supply requires a minimum dynamic pressure of 20 psi and maximum
of 50 psi (at the pre filter gauge). Feed water supply tubing should be large enough to
provide the required feed flow rate for the SRO. Connect the water supply from your
isolation valve to the INLET of the pre filter.
6. Connect the REJECT WATER to an open drain, maintaining a 2” air gap.
7. Connect a product line to the fitting marked PRODUCT WATER.
8. Remove and discard the 5 micron sediment filter (part number 20-1051) that has been
factory installed and Install the supplied 10 micron Carbon Block filter cartridge (part
number 20-5101).
9. Always maintain water flow and pressure to avoid damage to the RO pump.
CAUTION: To ensure proper assembly, all tubing extensions MUST be fully inserted
into fitting bodies, to the tube stops.
10. Plug the power cord into a dedicated 120-volt, 20-amp GFI receptacle.

3.0 SYSTEM START-UP
WARNING: This Reverse Osmosis System (RO) contains a preservative solution to
prevent microbiological growth and freezing. Discard all product water for
at least two hours of operation before placing the RO in service.
NOTE: As each component is started and flushed of any debris, make sure to divert
loop water to the drain to flush loop of any debris as well.
For 00SRO1095 RO, refer to Manual 98-0150
For 00MW200 Silex Wall Mount Deionizer, refer to Manual 98-0160
For 0185-8000 Healthcare Storage Tank, refer to Manual 098-0001
For 0021003 Loop Endotoxin Filter, refer to Manual 98-0033

10 098-0003 Rev. B
3.1 OPERATION
Once the system has been started, the SRO will continue to make water until the float switch
is tripped upon high water level in the storage tank. At this point, the SRO will be placed into
standby (tank full) until the water in the storage tank reaches a low-level to open the float
switch. Once the float switch opens, the SRO will re-initialize and begin to produce water
again. In the event that the TDS is above the pre-determined set-point, the alarm lamp will
light and the HI TDS warning message will show on the display. This warning will clear when
the TDS drops below the Setpoint.
The DI polishes the water from the RO. The DI continues to polish the water until the
resistivity light senses that the incoming water is above the threshold value of 200,000 ohm.
At which point, the resistivity light will turn red showing a warning of the water quality being
above the pre-determined set-point of 200,000 ohms.
The Endotoxin filter will remove endotoxins from the feed water, sending the filtered water to
the loop.

11 098-0003 Rev. B
4.0 MONITORING
Under AAMI TIR34 requirements, the below listed items need to be monitored on varying
intervals.
1. Ultra filters are to be monitored daily for a pressure drop. The pressure drop across
the filter that indicates the need for replacement is 15 PSI.
2. Reverse osmosis systems should be monitored in accordance with the facility’s quality
management system, using continuous-reading monitors that measure product water
quality (total dissolved solids). These measurements can provide a measure of
equipment performance.
3. Cartridge filters are to be monitored daily for a pressure drop. The pressure drop
across the filter that indicates the need for replacement is 15 PSI.
4. Water storage tanks are to be monitored monthly for the three listed specifications:
a. Bacterial count –Utility and critical of <10 cfu/mL
b. Tap, softened, deionized water of <200 cfu/mL ²
c. Endotoxin- Critical Water of <10 EU/mL²

12 098-0003 Rev. B
Fill out the monitoring log daily. Having this information available will help to quickly diagnose
issues related to performance. Failure to carry out the daily monitoring and maintenance at
the indicated intervals will result in reduced performance of the SRO system and may void
the warranty.

5.1 WINTERIZATION
Step 1 –
Disconnect all Power sources.
Filter housings- Open the sample ports to all filter housings in the system (i.e. RO prefilter,
Wall Mount DI, Endotoxin filters) to relieve water pressure. Open filter housings, remove
filters cartridges and discard cartridges. Undo any plumbing connections to the filter housing
that will not allow water to freely drain from the fitting.
Step 2 –
Drain water from system. Open all plugs. Disconnect all joints. Save all plugs and O-rings /
gaskets. (Fig. 5.1)
Step 3 –
Gages –Because gages are liquid filled. Remove from RO, Storage Tank and from
Endotoxin Filter. Store in an area above 34 degrees F. Gages are located on face plate of the
RO and top of the Pre filter housing, Return on the Storage Tank and the inlet and outlet of
Endotoxin filter. (Fig. 5.1)
Step 4 –
Membranes –Remove membranes from housings and discard. Disconnect joints to
membrane. Remove all water pooling in any joints. Remove any connection that will not allow
water to free flow out of it. Uncouple the product line and drain all water. Remove any fitting
that will not allow water to flow freely out of it. (Fig. 5.1)
Step 5 –
