2. Metal compression nut fitting:

(comes with 1 insert, 1 sleeve, 1 nut) This is for feed water adapter

-needle valve only.

Fitting Types: There are 2 types of fittings provided for connecting the system

Important! Use plastic sleeve and inserts on the plastic tubing we

provide. Do Not use metal sleeve or insert on plastic tubing or the

connection will leak!

How to connect: - See Fig.1B. Slide the compression nut onto the tubing.

- Slide the

plastic sleeve onto the tubing.

- Insert the “insert” into the tubing.

- Insert the tubing into the opening of the fitting.

- Slide the brass nut up, then tighten nut with a wrench. No Teflon tape!

(An extra metal sleeve is provided in case you need to connect your own metal

tubing. Use Teflon tape if connecting metal tubing.)

1. Quick-Connect (QC) fitting: (no insert, sleeve, or nut) Most of the fittings on the RO unit are this

type.

How to Connect: - See Fig.1. Push the tubing into the Quick-Connect fitting, then gently

pull back on the tubing to make sure connection was secure.

- No inserts, sleeve, or nuts are needed to secure the connection.

- No Teflon tape is needed!

To Disconnect: - See Fig.1A. Push in and hold down on the collet ring square against

the fitting. With the collet held in this position the tube can be removed.

THERE ARE TWO PARTS TO INSTALLING THE RO SYSTEM:

Part I. Assemble the filters and housings onto the main system

Part II. Installing the system

Note: The RO Membrane Element has already been pre-installed.

PART I. ASSEMBLE THE FILTERS AND HOUSINGS ONTO THE MAIN SYSTEM

Remove plastic/paper wrappings on the 3 filters, put them into the 3 housings, and assemble the

housings onto the main system as follow:

1. See

Fig. 2 Stand the 3 housings upright. Make sure each housing has a rubber O-ring in its

groove.

Put the APEC Sediment filter (1-SED10) into the “1

st

stage” housing on the right.

Put the APEC Carbon filter (23-CAB10) into the “2

nd

stage” housing in the middle.

Put the APEC Carbon filter (23-CAB10) into the “3

rd

stage” housing on the left.

2. See

Fig. 3 Starting from the 3

rd

stage housing on the left, hand twist the housing onto the main

system turning counterclockwise, one by one, for all 3 housings.

3. See

Fig. 4 Use the wrench provided to completely tighten the housing starting from 1st-stage.

Repeat this step for the 2

nd

stage housing in the middle, and for the 3

rd

stage housing

on left.

Note: For some people it is easier to use the wrench with the system laid down

(face up).

4. See Pg. 3 Remove 2 end plugs (white color) from Point 10 & 12

PART II. INSTALLING THE SYSTEM

Space: Make sure there is sufficient space under the counter for installation (an area of about

17”L x 6”W x 18”H for the system, 11”D x 18”H for tank).

The RO system is best installed under the kitchen sink. But if that is not feasible you

can install the system anywhere where there is a cold water supply with sufficient

water pressure for the chosen RO model, and an outlet to drain off the waste water

from the system.

Mounting: No need to mount the RO system on the wall. The RO system can stand in the sink

cabinet without mounting, this makes future filter change easy and convenient. If

you prefer to mount the system to the wall, please make sure it can be taken down

easily for filter replacement.

Feed Water: RO systems are designed to treat both hard and soft water and can handle incoming

TDS levels up to 2000ppm.

Step 1: Feed Water Connection

The RO system must be connected to the COLD water supply only!

1. Locate the Cold water supply valve under the kitchen sink (the round or oblong handle on

the right side). Turn off the incoming cold water completely by turning the shut off handle

clockwise.

Note: If the cold water shut off valve can not turn off the water, the main water supply

to the house must be shut off for the installation. Another option is to use a “self

piercing saddle valve” from APEC or from a local hardware store.

2. Feed Water Adaptor (1/2” or 3/8”): See Fig. 5. The Feed Water Adaptor comes with a

separate Needle Valve. The Adaptor goes inline onto your 1/2” or 3/8” cold water pipe. The

Needle Valve portion screws onto the Adaptor as shown in Fig. 5A.

MOUNT DRAIN

SADDLE AT

EITHER

LOCATION

Step 2: Drain Saddle Installation

Note: To avoid annoying drainage noise, mount drain line as low as possible

on the vertical tailpiece, or on horizontal tailpiece.

There is constant water pressure “packed” inside the RO system which blocks the waste water

from backing-up into the system. So the waste water is “forced-drained”, not “gravity-drained”.

1. See Fig.7. The drain saddle assembly should be installed above the trap and on the vertical

or horizontal tailpiece . To reduce the drainage noise, mount the drain line as low as possible

above the trap, or on the horizontal tailpiece.

2. See Fig.8. Mark the position of the hole on the drain pipe and drill a 1/4’’ hole through one

side of the drain pipe . There is a piece of self-adhesive sponge provided. Glue this sponge

to the inside of the saddle, this will cushion any gap between the saddle and the pipe. Make

sure the hole on the sponge is thoroughly punched out, and is aligned to the hole on the

saddle.

Step 3: Drill A Hole For The RO Faucet

Drill 1/2” diameter hole for standard RO faucet. (Air-Gap faucet: drill 1&1/4” hole.)

For best results use a 1/2” carbide-tipped masonry drill bit.

Wear safety glasses to protect your eyes while drilling the faucet hole.

Note: No need to drill a hole if an existing hole is available:

a) Spare hole: If there is a spare hole in the sink covered by a chrome cover, simply remove the chrome

cover and install the RO faucet there.

b) Spray hose: If the spray hose is not in use, remove the hose, and mount the RO faucet there. Remember

to plug up the outlet under the main faucet. If the spray hose uses a diverter at the base of the spout, be sure

to remove it to avoid trouble later on.

c) Hanging faucet: If drilling a hole is not feasible (i.e. rental home, drill tool not available etc.), the faucet

can just hang on the cabinet door or wherever that is convenient. Be creative!

When drilling a hole for the RO faucet, choose a location that looks good, works well, and is most con-

venient for dispensing pure water. An ample flat area is required for the faucet base so that the faucet

can be drawn down tightly.

1. Faucet location: Make sure the faucet stud will be accessible from below when the hole is drilled.

If space is not available on the upper sink area, the faucet can be located on the counter top by the

edge of the sink. If the counter top is ceramic tile, the method for drilling the hole will be the same as

for porcelain sinks.

2. For Stainless Steel Sink: Before using a 1/2” carbide drill bit, an indent should be made with a

center punch to keep the drill bit from walking. A small pilot hole will also aid the drill bit.

3. See Fig.9, 9A. Make sure to align the drain saddle hole to the drilled hole perfectly.

Mis-aligning these two holes will block the drain water and cause membrane damage. Attach the

drain saddle to the drain pipe and tighten the two screws evenly.

4. Once the drain saddle is secured, push 1/4” black drain tubing into the Quick Connect fitting on the

saddle. DO NOT use a “Insert” on the drain tubing.

Faucet Base

Step 4: Mounting The Faucet

1. Mount the faucet as shown in Fig.10.

Fig. 10

2.

Attach threaded end of faucet adapter to the

faucet metal stem. No teflon tape needed here.

3. Connect the Clear line to the faucet.

4. The faucet has a solid metal handle

that controls the flow of purified water

exiting the faucet. Turn the handle to

horizontal position to release the water

and vertically to shut off.

3. For Porcelain Sink: Porcelain enameled sinks can readily be chipped if care is not exercised

when drilling the hole. Before starting the drill motor, apply firm downward pressure on the bit

until a crunching occurs. This will help keep the drill bit from walking when starting the hole.

A small pilot hole will also aid the drill bit.

Note: Immediately after the hole drilling is done, clean up all metal chips, as metal chips

will stain the porcelain!!

Step 5: Positioning The System

1. Main System: The main system can stand in the sink cabinet. No need

to mount the system to the wall. If you prefer to mount the system to the

wall, please make sure it can be taken down easily for filter replacement.

2. Tank: The storage tank can also lay on its side if needed. The tank works fine in this

position. If the tank cannot fit under the kitchen sink, it can be placed elsewhere up to 20 feet

away from the RO system without much pressure loss.

Details on Tubing Connections:

To ensure a smooth and correct installation, please connect the water lines following the se-

quence and order outlined below. Refer to Fig.11 & 11A for proper point locations.

1. Point Z Faucet connection:

Tubing color: Clear tubing. Connect the CLEAR tubing to the base of the RO faucet.

Fitting type: Quick Connect Fitting. Simply push Clear tubing into Quick Connect fitting. No Insert,

Sleeve or Nut needed here. (Attach threaded end of faucet adapter to the faucet metal

stem. No teflon tape needed here)

2. Point X Feed water connection:

Tubing color: Red tubing. Connect the RED tubing to the Feed Water Needle Valve.

Fitting type: Metal compression nut fitting.

See Fig.1B on page 4. Use plastic sleeve.

Add “insert” to tubing. No teflon tape here. Tighten nut with wrench.

Tips!

If Point X leaks after you have tightened the brass nut, check to make sure you did put the

plastic “insert and sleeve” onto the tubing. If the insert is already in place, then try

applying Teflon tape from the threaded metal stud all the way to the plastic tubing, wrap

the whole connection with 8-10 rounds of Teflon tape. Smooth out the tape on the

threaded part with your fingers. Tighten brass nut again. This should stop the leak.

If the plastic sleeve is damaged, you can use the metal sleeve, but you need to apply

Teflon tape as described above, this should stop the leak.

Using RO for Ice-maker only:

If you want the RO to feed your ice-maker (fridge) only, you should still connect the RO faucet

as a 2nd outlet. This allows you to drain the tank, flush new filters through the faucet rather than

through your icemaker line. You can hang the faucet by the system and not mount it.

Option: Multiple Outputs - Add Shut Off Valve:

If your RO is feeding several output points (icemaker, fridge, bathroom), you should add a

Shut-Off valve to each output line (except the RO spigot line). This way, if you ever need to

diagnose a problem in the system, you can easily shut off these lines to isolate the water flow for

accurate troubleshooting.

Step 7: System Start-Up

1. Turn on feed water: Slowly, turn on your Cold water supply. Turn on the Needle Valve (turn

counter-clockwise) to allow the raw water to enter the system. Check for leaks!

2. Turn on tank valve: Turn on the tank’s ball valve to allow water to enter the tank. The

tank’s valve is “ON” when the valve handle is parallel (in the same direction) with the valve’s

outlet (see Fig.12). Check for leaks!

3. Wait for tank to fill: Before usage, allow the tank to fill. Tank normally takes 2-3 hours to

fill. When the tank is filled, the RO will shut off automatically.

4. Drain Tank: Please do not use the first tank of water. Once the tank has filled, open

the drinking water faucet to drain the tank and filters. It will usually take about 5 min-

utes to flush the unit. When the tank is completely empty water will simply Trickle out the

faucet. At this time, please close the drinking faucet and allow the unit another 2-3 hours to

refill the tank. The 2nd tank of water will be ready for use.

Please Note: Water may come out dark for the first few seconds on the initial flush, and then

clear right up. This is due to the GAC (granular activated carbon) post filter.

5. Clean up area: Allow the system to run while cleaning up tools and work area.

6. Check for leaks! Make sure no leaking at joints, fittings, valves, and tubing connections.

Congratulations! You have successfully installed the Reverse Osmosis System!

Note:

If your RO makes an annoying noise. See Troubleshoot Guide section for explanation and

instructions on page 29.
