TIGHTEN
– 1/4 turn after hand tight is usually sufficient. Repeat with one of the carbon
block cartridges in the middle housing (three-housing WR2 units only) and with the other
carbon block cartridge in the right hand housing.

Remove the membrane element from its wrapping. Disconnect the ¼” tube attached to the
membrane housing end cap. Unscrew the end cap from the membrane housing. The
membrane housing is mounted horizontally on the system’s mounting bracket. See Figure
1. Insert the membrane element into the housing, o-ring spigot first. Gently push until the
membrane seats snugly inside the housing. Re-install housing cap and poly tube.
Step 10. Starting Up the System
1.
Make sure that the Sani-purge valve (see figure 4.) is CLOSED.
Open cold water
supply valve and let RO system fill with water. Check for leaks and tighten any joints if
necessary
2. Model RO-4152H only: Insert the plug into a standard wall receptacle. System pump will
switch on and begin to operate
.
3. Let the system operate for about 10 minutes. Close the storage tank valve and open the
faucet until product water drips out. Check for leaks again and fix if necessary.
!
DO NOT USE ANY WATER FROM THE SYSTEM UNTIL THE NEXT STEP IS COMPLETE.
4. Open the storage tank valve and close the faucet. The system is now operating and filling
the storage tank. Allow the tank to fill completely and the system to automatically shut itself
off. This step may take 1-3 hours or more. Open the faucet and let the entire tank drain
completely. You will see dark carbon dust briefly flush from the carbon filer cartridge
– this
is harmless and normal for the first flow of water through the cartridge. Allow the system to
re-fill the tank. Once completed, your system is ready for use.
Section 3: Operation and Maintenance
Operation of your Reverse Osmosis System is simple and easy. This appliance is fully automatic
and can be enjoyed without complicated operating procedures. Be sure to follow the cartridge
replacement schedule to ensure peak performance and long membrane element life.
Changing Filter Cartridges and Sani-Purge Procedure
The filter cartridges should be changed, as a rule of thumb, every three months. It is critical that
this be done, to ensure that chlorine is not allowed to attack the membrane film. Always Sani-
purge the complete system at the same time that the cartridges are changed.
!
THOROUGHLY WASH HANDS BEFORE LOADING CARTRIDGES AND MEMBRANE
ELEMENTS.
