2. Remove the wrapping from the membrane element(s). Lightly lubricate the membrane brine seal
and all o-rings located in the membrane housing caps with a good quality, silicone o-ring lubricant
(do not use petroleum-based lubricants). Disconnect the connections on the membrane housing’s
top end cap. Remove the end cap from the membrane housing by loosening the band clamp
nuts and bolts. The membrane housing is mounted vertically on the system’s stand. See Figure
1. Insert the membrane element into the housing, so that the brine seal of the membrane will
seat at the inlet side of the membrane housing (this is indicated by the direction of flow label on
the housing). See Figure 3. Gently push and slowly twist until the membrane product adapter
seats snugly inside the housing cap still in place at the bottom of the housing. Re-install the
disassembled housing cap - be sure that o-rings do not roll out of their grooves, get pinched or cut.
Re-install the band clamp snugly and reconnect the connections to the cap.
3. To remove the membrane from the housing, remove the top housing end cap and gently pull the
membrane out of the housing body. You may need to lightly grip the membrane cage with needle-
nose pliers to free it from the housing, after extended use. With each disassembly, always check
the end cap o-rings and the membrane brine seal to make sure that they are in good condition
and are secure in their seating grooves. While the housing is disassembled, clean all components
thoroughly to remove any debris or scaling. When re-assembling, make sure that the membrane
element is installed with the brine seal facing in the same direction as it was previously. See
direction of flow label on each membrane housing. In order to monitor TDS reduction a TDS monitor
is available. Order Part # RSXTDS
Step 6. Install the Feed Water Supply Connection
1. Inspect the cold water supply line and the condition of the pipe. Ensure that the supply pipe is in
good overall condition and is capable of delivering the system’s necessary feed water flow rate.
See Section 8 for specified feed water flow rate requirements.
2. Turn the water supply line to your plumbing OFF.
3. Plumb a connection from the COLD water supply line, ensuring that the feed line is at least 1/2” in
diameter. Install a shut off valve on the connection, so that the RO system can by isolated from the
main water supply. Note that the inlet connection to your RO system is 3/8” push in fitting. Push
the 3/8” tube into the fitting following directions in the previous section. You may now turn the water
supply to the plumbing system ON. Check for leaks around the RO connection. Purge air from the
filter bowl by pressing the red button on top of the filter housing until no more air comes out. Correct
any leaks, if necessary.
