SYSTEM SHUTDOWN
Ordinarily, an MRO2-5X is connected to a water use system that is used continually or very
frequently. Therefore, frequent shutting down is not necessary. Most usually, the MRO is
connected to a Direct Feed Loop or Storage Tank of a Central System. If so, the MRO should
be cycled using the “Membrane Flush” feature in the controller of the MRO. This will allow an
MRO connected to a Direct Feed Loop while in STANDBY to start and circulate Product Water
through the loop at some predetermined frequency for a predetermined amount of time (every 4
to 6 hours for 15 minutes, for example). Thi
s allows the water to be “freshened” in the MRO
and loop. When the MRO is connected to the storage tank of a central system, the MRO shall
remain in OPERATION. When the “Membrane Flush” feature is active, the MRO will cycle on
some predetermine frequency
to send the Product Water through the “Divert to Drain” feature of
the MRO to the drain. This will only occur when the “Tank Full High” limit switch indicates that
the tank is full for a long period of time (usually around 6 hours) since the last use of the MRO.
If the MRO must be shut down for an extended period, however, use the following instructions:
1. Before turning off the MRO by pressing the POWER key, turn the REJECT VALVE
counter clockwise to allow a full-
flow “FLUSH” 5 minutes. This will flush the concentrate
out of the system.
2. Press the POWER key (the display will show STANDBY).
3. Turn off the potable tap water supply to the system.
4. Disconnect the PRODUCT WATER hose from the Direct Feed Loop or Storage tank,
and the INCOMING TAP WATER hose from the potable tap water supply. The hoses
may be connected together to prevent dirt from entering the hoses.
5. Remove the REJECT WATER TO DRAIN HOSE from the sink. The hoses and power
cord may be secured by the hose strap on the side of the MRO for storage or transport
of the MRO.
6. Store the system until next use.
7. When transporting the MRO, push or pull the system carefully, because it may be top-
heavy and may easily tip over.
