2. WATER SUPPLY (feed) - Turn off the water supply. Place the 3/8” brass compression valve
in the cold-water line. Attach one end of the 3/8” tubing to the valve using the brass insert and
nylon sleeve provided and attach the other end to the RO unit filter connection marked
“FEED”. See the SYSTEM LAYOUT drawing.
3. DRAIN LINE (concentrate or reject) - Attach the drain saddle tee to the 1-1/2” outside
diameter drain pipe. Drill a 3/8” hole into the pipe. Insert the 1/2” npt x 3/8” compression
fitting into the saddle tee. Attach the 3/8” tube and connect it to the reject fitting. See the
system layout drawing.
4. SERVICE LINE (permeate or product) - Drill a 5/8” hole in the sink top (use a carbon tungsten
drill bit) and attach the chrome faucet. Attach the 1/4” outside diameter tubing from the tee
(marked permeate) to the compression tee on the pressure tank and then to the compression
nut on the bottom of the faucet. See the system layout drawing.
5. ON CHLORINATED WATER - You
must rinse
the activated carbon cartridges. Do this by
placing a container under the sample port, (see the system layout drawing, item 21) open the
valve 4 or 5 turns and turn on the water supply. Continue this procedure until no more black
color appears in the water.
The unit is factory tested at a 5 to 1 recovery ratio. Rejection of the TDS (Total Dissolved Solids) is at
least 90% at 185 PSI, 78° F and 1000 PPM TDS.
NOTE: If the RO pump pressure exceeds 190 PSI:
1. Remove the acorn nut on the right side of the pump
2. Using a common screwdriver, turn the slotted screw counter-clockwise to decrease pressure.
3. Replace the acorn nut.
WARNING: PUMP WARRANTY IS VOIDED IF THE PRESSURE EXCEEDS 190 PSI
NOTE:
Pump model units will automatically shut down when the pressure in the holding tank reaches 40
PSI. Back pressure on the holding tank should not exceed 40 PSI. The RO pump will start automatically
when the product pressure drops below 20 PSI.
V OPERATION
NOTE:
On new installations, do not allow any product water to flow into the storage tank until the RO unit
has run for one hour and is thoroughly flushed. This will insure the removal of all traces of the
preservative from the membranes. Do this by shutting down the storage tank valve and opening up the
faucet and let the water run into the drain. Be sure to re-open the storage tank valve for normal operation.
1. After all water hook-ups are complete, turn the water supply on and check for leaks.
2. To start the RO unit, plug in the RO unit using the 3 prong plug in a standard 115 volt outlet or
220 volts if designated for 220 volt power.
3. The unit will not operate unless the feedwater pressure is 20 PSI or higher.
4. The system is equipped with a preset reject water flow controller. No adjustments are
required for setting flow rates.
