BEFORE POWER TURN ON
The controller should be installed in the controller housing before connecting electrical
power to the unit.
WARNING
Personal injury and permanent damage to the controller can result if the
controller is installed with power on the unit.
Once the inlet water is plumbed to the system and the electrical power is connected, the
electrician should verify correct motor rotation. Please refer to
the Pump Information
included in the Appendix.
CAUTION
Verify that all retaining rings are in place on the RO membrane housings
before turning on the pump.
CAUTION
Be sure the product water will not enter the user system during startup.
The RO system must be operated for four hours to flush out the
preservative solution before connecting to the user system.

INSTALLATION OF REVERSE OSMOSIS MEMBRANE(S)
RO units are normally shipped with the membranes installed and preserved in sodium
bisulfite solution. However, should the need arise, the following procedures may be
followed to install membranes:
A.
See the Appendix for a diagram of the individual components of the membrane
assembly. Before sliding the membranes into the fiberglass housing, install the
proper product tube adapters on/in the product tube. Lightly lubricate the o-rings
with glycerin.
B.
Load the RO membrane into the fiberglass housing from the direction in which
the feedwater will enter, inserting the end without the chevron seal first. Before
the chevron seal enters the housing lightly lubricate the chevron seal with
glycerin before it enters the housing and press the membrane to the end of the
housing.
C.
Place an end plug into the RO housing end opposite from loading end. Using
snap ring pliers secure the end plug with the retaining ring. Press the membrane
into the end plug to seat. Hoses should be connected to end cap before
insertion into the housing.
WARNING
Never engage or disengage retaining rings without wearing safety
glasses.
D.
Install the adapter and end plug on the feed end and secure it with a snap ring.
CAUTION
Never allow the RO membrane to dry out once it has been wet, or
irreversible damage will result.
