 Installation Step 5
Drain Saddle Valve

A Drain Saddle Valve is used to connect the waste water line to the drain
pipe under the sink, and is designed to fit around a standard 1 1/2-inch OD
drain pipe. The drain saddle valve should always be installed before (above)
the p-trap and on a vertical or horizontal drain pipe. To avoid clogging the
drain line with debris, do not install the drain saddle near a garbage disposal.

1. Position the drain saddle valve at selected

location and mark for the opening.
2. Drill ¼ -inch (6.3mm) hole at mark through
one side of pipe.
3. Remove backing from gasket and place
adhesive side to the fitting half of drain clamp
around hole.
4. Position both halves of drain saddle on
drain pipe so the opening aligns with drilled
hole. Use a small drill bit to verify that drain
clamp is properly aligned.
5. Secure drain saddle clamp on valve with
bolts and nuts provided. (Do not over tighten,
and make sure there is equal space between
saddle halves on each side.)

 Installation Step 6
RO Faucet

(If Applied)

14

Downloaded from www.Manualslib.com manuals search engine

 The RO Faucet may be installed on any flat surface. Check the underside of
the location for interference. You may use the existing hole on the sink or
drill a new hole.

Make sure the washer is big enough to cover the hole. If you drill a new
hole on the countertop or sink, make sure that drilling the hole will not
damage any pipe or wiring underneath the countertop or sink.

Stainless Steel Sink

1. Determine the desired location for your RO faucet on your sink surface.
2. Place masking tape or duct tape on the determined location for the hole
to be drilled.
3. Use a variable speed drill set on slow speed and drill with a 1/8 inch
(3mm) drill bit to make a center hole at the select location.
Note!
Use water or lubricant to keep the drill bit cool while drilling.
4. Enlarge the hole using a ¼ inch (6.4mm) drill bit. Use factory approved
method or approved plumbing practice to drill hole in sink.
5. Enlarge the hole to 1/2-inch diameter. Keep bit well lubricated and drill
slowly.
6. On top of the sink, insert the chrome base plate (Escutcheon plate), and
the large rubber washer in that order over the threaded mounting tube at
the base of the faucet (If Applied).
7. Under the sink, install the large metal (or plastic) washer and the star
washer (or lock washer) over the threaded stem. Screw on the nut and
tighten.
8. Connect the freshwater line sleeve over the brass compression nut and
the white plastic ferrule (do not use the brass ferrule) over blue tubing, then
push to the end of the threaded stem. Screw on thecompression nut and
tighten or use the quick connection adapter (PLEASE REFER TO PAGE 14)

Porcelain Sink
To drill on a porcelain sink, a spring-loaded Relton style drill set is strongly
recommended to prevent chipping. Avoid high speed drilling during the initial
cutting of porcelain as this can cause chipping.

 Installation Step 7
RO Tank Assembly

NOTE!
Do not tamper with the air valve on low side of storage tank.
It has been preset at 7–10 psi by the manufacturer.

1. Open the box and remove the stand from the top of the tank.
2. Wrap the thread 6-8 times with plumbers (Teflon) tape only.
3. Connect the ball valve to the thread. Make sure it is tight but not overly
tight.
4. Place the storage tank in desire location. Since it is the pressure storage
tank, it can stand up straight or lie down.
5. Connect the (yellow) tubing from the T connection of the post carbon inline
filter (10th stage) to the tank ball valve. (See Alkaline system diagram page 6)
6. Turn the tank ball valve on.

 System Startup
1. Turn on both the cold water supply and the under sink feed-water valve,
but close the tank ball valve. If any leaks are noted, turn off valve and
correct before proceeding.
2. Open RO faucet for continuous flow (flow rate may vary).
3. Check system for leaks; tighten when necessary.
4. After 5 minutes, the water will start to drip out of the RO faucet. Let it
drip for about 10 minutes and then flip the handle to the closed position.
Turn on the tank ball valve. It will take several hours (2-3) for the storage
tank to fill, depending on the incoming water pressure.

DO NOT DRINK THE WATER FROM THE FIRST TANK PRODUCED BY

YOUR NEWLY PURCHASED SYSTEM.

5. After the tank is full (you will hear the water stop), flush the system by
placing the RO faucet in the open position until the water is completely
discharged.
WATER FLOW WILL CHANGE TO (DRIPPING) DEPENDING ON YOUR
WATER PRESSURE.

6. Upon complete discharge of storage tank, turn handle to closed position

on RO faucet and let the refilling process begin.
This process could take 2-3 hours to complete.
*******(REPEAT STEP 5 & 6 THREE TIMES)*******

7. After the fourth tank is filled, you may drink the water.
8. Check for leaks daily during the first week of use and periodically
thereafter.
9. You may notice that the water may be milky colored during the first
week. This is an indication of air bubbles in the water; it is normal and safe.

 System Maintenance
This recommendation is intended for maximum efficiency of RO SYSTEM.
1. Filter maintenance
a. It is OK to store filters for several years.
b. To keep the unopened filter sealed, place it into an airtight container,
preventing it from absorbing air. This prolongs the shelf life of the carbon
filter and avoids any possible odor from the air.
2. Membrane maintenance
a. The dry-packed membrane usually has a two-year shelf life. To prolong the
shelf life, keep unopened dry membrane in the refrigerator.
b. Once used, run the RO system every day for at least 10–15 minutes (about
1 gallon or 4 liters of drinking water). This helps maintain the membrane
performance.
c. If you will not be using the RO system for weeks, drain the storage tank
completely. Fill the tank and drain it twice before using the RO system again.

THIS RO SYSTEM CONTAINS FILTERS THAT MUST BE REPLACED AT

REGULAR INTERVALS TO MAINTAIN PROPER PERFORMANCE.
USE ONLY FACTORY-APPROVED FILTERS.

How to sanitize your drinking water system (Recommended once a year).

1. Close the incoming water (Feed Valve)

2. Open drinking water faucet and drain the system completely and then
close the faucet.
3. Remove ONLY the following filter cartridges:
(Stage 1,2,3 Bottom Filters + Stage 4. Membrane)
Stage 1 Sediment
Stage 2 GAC
Stage 3 Carbon
Stage 4 RO Membrane
4. Mix 1 gallon of water with 2 tbsp of household bleach.
5. Fill up the bottom filters housing with the solution and close them.
6. Open the incoming water to the system (Feed Valve) and let it run for 10
minutes.
7. Open the drinking water faucet and let it drain for 10 minutes.
8. Close the drinking water faucet and wait for 10 minutes and then open
the drinking water faucet again and completely drain. (If you smell the
household bleach from the drinking water faucet, repeat steps 7 and 8)
9. Now you are ready to replace the filter cartridges.

 Filter Change

How to change the 1st, 2nd and 3rd stage fitlers

1. Turn off the water supply connected to the Reverse Osmosis system and
Tank Valve (if applicable) -- then open the dispensing tap downstream to
release pressure.
2. After releasing pressure, place the filter manifold in a bucket and unscrew
the filter sumps using the filter wrench to loosen the housings. Keep track of
which filter came from which housing.
3. Throw out the old filters and wash the filter housings with dishwashing
soap then proceed to rinse well with cold water. Ensure your hands are
washed and clean before unwrapping the new filters. Place filters inside the
correct housings, making sure the O-Rings are in their proper location
(within the ridges of the housing) before you tighten the housings.
Do not overtighten.

Turn Left to OPEN

Turn Right to CLOSE

How to change the RO Membrane and top filters

1. Open the membrane housing by unscrewing the cap, then pull out the
membrane with a pair of pliers. Be sure to note which side is the front and
which side is the back. Wash out, rinse and refill housing with new membrane
making sure to push it in firmly then close the housing by tightening it hand
tight.
2. Replace the Alkaline Filter by removing the 2 elbows from both sides of the
filter. Detach the filter from the holding clips and push the new filter into the
clips. Connect both elbows back (check the direction of flow).
3. Top filter (Inline Carbon) please remove the locking clip (if any) from the
two ends. Using your fingernail, push the collet in while pulling the

20

 connection to disconnect the fitting from the two ends of the filter. Discard
the old filter and connect the fitting to the new post carbon filter.
4. Now you can fully open the inlet tap and the tank valve (if any) and
empty the tank. Then, let the system refill with water, this process typically
takes 2 to 4 hours. You can open the dispensing tap briefly to release any
air trapped inside the system while it’s filling. Note: the first few cups of
water may be black in color due to carbon fines. (Be sure to check
for leaks in the first 24 hours.)
5. After it has filled for 2-4 hours, drain the entire system by opening the
faucet until water flow is reduced to a slow trickle, then, close the faucet
and repeat the procedure 3 more times. If the system is connected to a
refrigerator, do not drain the system through the refrigerator water
dispenser, the carbon fines from the new carbon filter will clog the internal
fridge filter.

Make sure the O Ring is in place before

you tighten the Membrane Housing Cap
