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 right.
Note: For some people it is easier to use the wrench with the system laid down (face up).

PART II. INSTALLING THE SYSTEM
Space: Make sure there is sufficient space under the counter for installation (an area of about
12”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 RO-PERM, and an outlet to drain off the waste water from the system.
Mounting: No need to mount the system on the wall. The 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” to 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.

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.
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 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.

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.
3. 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.

Permeate In: Pure water enters pump from Membrane pure water output
Permeate Out: Pure water exit pump to tank
Brine In: Brine/ wastewater enters pump from Membrane waste line
Brine Out: Brine/ wastewater exit pump to drain pipe
Arrow: Make sure “arrow” on pump is pointing upward after installation.
How The Permeate Pump Works:
The permeate pump has a built-in Auto-Shut-Off (ASO) feature that functions like the ASO valve on a
non-pumped system, so you don’t need a separate ASO valve on the system.
The pump operates by collecting the RO’s waste water, and storing it up in the pump chamber for a few
seconds (interval depends on water pressure) until sufficient pressure is built up. Then it uses that pressure
to spurt the pure water into the tank. The pump will make clicking and spurting sounds. If the sound is
too loud, just add some buffering material around the pump, or put the RO system in a cabinet where the
sound is less audible.

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.
Ball Valve
(Recommended)
Tee tting for
icemaker
Option: Ice-maker Connection
If you want to connect product water from the RO to your ice-maker, you will need:
x One T-fitting, preferably the quick-connect type fitting
x Extra ¼ “ tubing long enough to go from the RO system to your ice-maker
x Optional: One shut-off valve, preferably the quick-connect type.
See Fig.13. Before connecting the product water line from Point Z to H, add a T-fitting near
point H to divert product water to both the ice-maker and the faucet. It is best open the line to
the ice maker after the first tank has been discarded and the 2nd tank has completely filled.
