BEFORE POWER TURN ON
The controller circuit board 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 start-up.
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)
A.
U.S. Filter RO units are normally shipped with the membranes installed and
preserved in sodium bisulfite solution. However, should the need arise, the
following procedure may be followed to install membranes.
B.
See the Appendix for a diagram of the individual components of the membrane
assembly. Before sliding the membranes into the fiberglass housing, lightly
lubricate the chevron seal and o-rings with glycerin. Be careful not to damage
the o-rings when inserting.
C.
Load the RO membrane housings from the direction in which the feed will enter,
inserting the end without an o-ring first. They should be removed from the
opposite end.
WARNING
Never engage or disengage retaining rings without wearing safety
glasses.
D.
Place an end cap into the RO housing end opposite from loading end. Hoses
should be connected to end cap before insertion into the housing. Secure the
end cap with the retaining ring. Snap ring pliers are very helpful for this
operation.
E.
Install the adapter and end plug on the feed end and secure it with a retaining
ring.
CAUTION
Never allow the RO membrane to dry out once it has been wet, or
irreversible damage will result.
