PT401 ANTI-SCALANT
Smaller AmeriWater MRO products have the PT401 antiscalant system equipped as an option.
The larger units, MRO2-5X4 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.

MEMBRANE REPLACEMENT PROCEDURE:
Turn off the incoming tap water supply to the MRO and unplug the device from the GFI
receptacle. Power down the disconnect for the motor starter. (The following procedure will
cause water to leak and spill

may get wet.)
1.
Place a container under the CHLORAMINE SAMPLE (TEST) PORT and slowly open the
port to relieve the pressure on the MRO system.
2.
Place a container under the PRODUCT SAMPLE (TEST) PORT on the front panel and
open to allow to drain.
3.
