8.2 PT401 ANTI-SCALANT
Smaller AmeriWater MRO products have the PT401 antiscalant system equipped as an
option. The larger units, MRO3 & 4 ordinarily have a complete water pre-treatment system
(backwashing particulate filter, backwashing carbon filter, and water softener) installed ahead
of the MRO. This eliminates the need for the PT401 anti-scalant system within the MRO, and
is not a point of discussion in this manual. If your unit has been fitted with a PT401 anti-
scalant system due to a water pre-treatment system not being installed ahead of the MRO,
refer to the PT401 manual.
8.3 MEMBRANE MAINTENANCE INSTRUCTIONS
There are two options available for membrane maintenance on the AmeriWater Portable
MRO System:
•
Purchase the AmeriWater Clean In Place System (P/N 00CIP1) and clean the membrane
yourself.
•
Use the membrane to failure and replace.
8.4 EXCHANGE PREPERATION
1. Turn off the MRO.
2. Turn off the incoming tap water supply.
3. Put a container under the CHLORAMINE TEST PORT. Slowly open the sample port
to relieve the pressure and let the water drain.
4. Unplug the MRO from the electrical outlet.
5. Open the access panel.
8.5 MEMBRANE EXCHANGE
Removing/Replacing the membranes varies in complexity depending on which membrane is
to be removed. Position the MRO near a drain or container because some water may spill on
the floor during the exchange.
1. Follow the exchange preparation steps listed in section 8.4.
2. Disconnect the tubing from the color-coded fittings on the membrane assembly (Water
will spill - you may get wet).
3. Remove the clamp securing the membrane assembly to the unistrut in the MRO
cabinet and remove the membrane assembly from the cabinet. If membrane #1 or #2
must be repaired or replaced, then the outer tier of membranes must be removed to
gain access.
