Page 8: Filter Housings Assembly
Stand the 3 housings upright. Make sure each housing has a rubber O-ring in its Fig. 2 groove. Put the APEC Sediment filter (1-SED10) into the “1 stage” housing on the right. Put the APEC Carbon filter (23-CAB10) into the “2 stage”... -

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. - Page 10 Fig. 5A - Needle Valve Installation. Attach the needle valve (C) to water supply adapter (A). Please apply 5-6 wraps of teflon tape to needle valve prior to connecting it to the water supply adapter (A). Fig. 5B - If your pipe has a 1/2” Connection. By attaching the 1/2”...
- Page 11 3. Recommend Connection For Flex Line Riser: See Fig.6A. & Fig. 6D. Loosen nut and separate cold water riser tube from faucet shank. Gently bend riser tube so that the Feed Water Adapter (Fig 5) fits onto the faucet shank. If your riser tube has no built-in washer, then fit the cone-shaped washer provided onto the riser tube.
- Page 12 Fig. 6C Fig. 6D Fig. 6E 4. Needle Valve: See Fig. 6C. Screw the Needle Valve onto the Adaptor tightly. Apply 6-8 rounds of Teflon tape onto Needle Valve before attaching it to the Adaptor. To open needle valve: Turn needle handle counter-clockwise. To close needle valve: Turn needle handle clockwise.

Page 13: Drain Saddle Connection
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. - Page 14 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 waste water and cause membrane damage. Attach the drain saddle to the drain pipe and tighten the two screws evenly. Fig.

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. -

-stage membrane to drain outlet — Black tubing. Please Note: The diagram below is for our Non Pump RO-45, RO-90 and RO-PH90. If you are installing the RO Perm or RO Pump, please refer to the diagram in the addendum. - Page 17 Fig. 11A 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.
- Page 18 3. Point W Waste water connection: Tubing color: Black tubing. Connect the BLACK tubing from the RO to the Drain Saddle. Fitting type: Quick-Connect fitting on drain saddle. No teflon tape. Do Not add ”insert” into Black tubing. Simply push tubing into port. 4.
- Page 19 7. Point Y Tank’s input & output connection: Prepare tank: See Fig.12. Apply 6-8 wraps of Teflon tape to tank’s threaded Output stem on top of tank (remove rubber cap if there is one). Screw tank Valve onto Output stem. Tubing color: Yellow tubing.
- Page 20 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.

Page 21: Maintenance
RO system will be contaminated. It’s best to use APEC replacement filters. Using “non APEC” and lesser qual- ity filters may clog up the RO system and damage the membrane. - Page 22 2) Open housing: Have the RO standing upright. Slip the plastic wrench onto the #1 housing. Looking down from a top view, you should open the housing turning clockwise. If necessary, lay RO down on the floor to get a better leverage. If the housing is too tight, use a hammer and tap on the wrench handle to help turn the wrench.

Fig. 14A Fig. 14B How to Replace Stage-5 Carbon Filter: Replace this last filter at the same time you replace the stage-4 membrane. 1) Remove the OLD filter: See Fig.14 A.

Page 27: Input Water Pressure: Most Important Factor
3) Water Pressure – The Most Important Factor! RO systems run on water pressure. Therefore your water pressure has the most direct effect on how well your RO will perform. With sufficient water pressure (85 psi max.), your RO system will function well, give high output with high rejection rate, and fill up the storage tank quickly. -
Page 28: Tank Volume & Delivery Pressure
6) How Full Can My Tank Fill Up? Your incoming water pressure determine how full and how fast the storage tank will be filled up. The stronger your input water pressure, the faster and fuller the tank can fill. If water pressure is low, the tank will fill slower and will not fill up to its full capacity. -

Page 30: How To Test Your Water Pressure
11) How to Test Your Water Pressure: Get a water pressure gauge that adapts onto your sink or garden faucet (from hardware store), attach gauge onto faucet, turn water on to FULL, then take a reading. For some areas, water pressure is lower during the day and higher at night when less people are using water. -

Page 32: Humming Noise
If the noise persists after a few days, that means there is air in your water source, or the current Check Valve is resonating with your water pressure and pipes, creating the noise. In this case, a new Check Valve will solve the problem. Contact APEC customer service for assistance. - Page 33 Output line is crimped —> Remove crimp Incorrect installation —> See Fig.11 & 11A. Verify all line connections. Tank defective, no pre-charge pressure —> Set tank pre-charge to 5-7 psi. ASO connection Error —> See Fig. 18A and Fig. 18B to reconnect ASO to the correct connection.

Do Not over tighten the housing. Step 4. Open the tank ball valve and feed water line. Check for leaks. If the filter housing contin- ues to leak, please contact APEC technician for replacement assistance. -

RO units will remove 90-95% of contaminants and impurities in the water. If the pure water is not at 90% or higher, please contact an APEC technician for assistance. 12) Air Bubbles: Lots of Air bubbles in cup or bottle when filling It is quite normal to see air bubbles in a cup of pure water. -
Page 39: Other Information
OTHER INFORMATION AirGap Faucet Installation There are 3 colored tubings on your Air-Gap faucet. At the end of each 1/4” tubing there is a “Quick Connect” fitting. The Quick Connect fittings is used to connect the Pure and Waste water line from the RO unit to the Air Gap Faucet. - Page 40 How wastewater is disposed via Air-Gap faucet: Waste water is routed through the Air-Gap faucet prior to being drained off into the standard drain- pipe outlet. The 1/4” BLACK waste water line from the RO system will discharge through the 1/4” RED line to the Air-Gap faucet.
