Step 4: Mounting the Drain Saddle Valve
1.
The drain saddle valve will fit most 2" standard plastic drain pipes. It should be installed above the trap and on the
vertical or horizontal pipe under the sink drain.
2.
Remove the nuts and bolts from the front half of the saddle valve. Position and hold it in the desired location on
the drain pipe above the trap and water line. Mark the spot for drilling with a 5/32" drill bit or awl through the
hole in the clamp. Do not mount the saddle valve next to a garbage disposal, as this may cause the drain line to
clog. You should carefully consider the route and available space for the ¼" poly drain line tubing before you drill
the ¼" hole.
3.
Where you marked the location in Step 1, drill a ¼" hole into the drain pipe and clean the surface of the pipe.
4.
Align the drilled hole in the drain pipe with the front half of the saddle valve using the 5/32" drill bit or a narrow
screwdriver.
5.
Locate the complementary piece of the saddle valve assembly clamp and join them together with the two bolts.
Tighten the bolts evenly.
6.
Connect ¼" tubing to drain saddle valve and the other free end to the flow restrictor valve. Please refer to
connection diagrams at the end of this manual for appropriate connection.
Step 5: Pressure Testing and Purging
1.
Check all tubing to be sure there are no kinks or obstructions.
2.
Turn the storage tank valve to the OFF position.
3.
Turn RO faucet lever to continuous flow ON position (handle pointed up).
4.
Turn the cold water supply valve on slowly. When the system is pressurized, check for leaks.
5.
You will hear the air purging from the system. Within 5 minutes the water should start dripping from the RO
faucet. Once the water starts to drip, allow 20 more minutes for the water to flow through the system and purge
trapped air.
6.
After 10 minutes, turn the storage tank valve to the ON position (handle is parallel to the tubing).
7.
Turn the RO faucet handle to the OFF position. Now the purified water will start going into the storage tank.
8.
CAUTION! You must purge the first two tanks of water from the system prior to consumption of the product
water. Do not drink the first 2 tanks of water produced by the system!
9.
Allow the storage tank to fill for 2 hours. Then open the faucet until the tank is empty and the flow just drips from
the faucet.
10.
Close the faucet and allow the storage tank to fill again for 2 hours. Then open the RO faucet and empty the tank
again. After discharging the contents of the storage tank twice, you can start enjoying the pure water.
11.
NOTE: Check for leaks daily for the first week after installation.
