How Reverse Osmosis works –
You r ne w SPECTRUM Premier Twist-Lock (PTL) Reverse Osmosis (RO) system is composed of a 3-stage system manifold, a PTL carbon block (PTL-CB) pre-filter, the reverse osmosis membrane (PTL-RO), a storage tank, a PTL-CB post-filter and an air gap tap to deliver the filtered water to your counter­top. First the water goes to the pre-filter, which is a replaceable cartridge that reduces chlorine, odour, sand, silt, dirt and other sediments to improve the taste of your water. Next, the water flows to the Reverse Osmosis membrane, which is a tightly wound membrane that reduces the total dissolved solids (TDS) and organic matter. The water goes from the membrane into the storage tank. A diaphragm inside the tank keeps the water pressurized to about 30 psi when the tank is full. This is what provides the fast flow to the tap. When the tank is empty, it should be pressurized to 5 – 7 psi. As water is drawn to the tap, it flows from the storage tank through the final filter. The final stage PTL-CB post filter reduces any remaining tastes and odours to provide cleaner great tasting drinking water direct to your tap.
You r sy st em a ls o ha s an a ut om at ic shu to ff v al ve t o co ns erve w at er. Wh en t he s to ra ge t an k is f ul l an d th e tap is not open, pressure closes the shutoff valve to stop flow of water with contaminants to the drain. After enough drinking water is drawn from the tap, the pressure in the Reverse Osmosis system drops and the shutoff valve opens to allow the tank to be re-filled.
Reverse osmosis uses a membrane that is semi-permeable, allowing cleaner water to pass through it, while rejecting the contaminants that are too large to pass through the tiny pores in the membrane. This quality reverse osmosis system uses a process known as cross-flow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected contaminants away from the membrane and down the drain. The process of reverse osmosis requires a driving force to push the water through the membrane - the pressure provided by your home’s water supply is sufficient: 40 to 100 psi.
What it removes –
The SPECTRUM Premier Twist-Lock reverse osmosis system has achieved NSF/ANSI 42 & 58 certification. NSF International is a world leader in standard, development, product certification, education and risk management for public health and safety. Your Reverse Osmosis unit, PTL-CB, will reduce Chlorine, Odour, Particulates, Sediment, and improve taste, according to NSF 42 Standard. The PLT-RO will also reduce Total Dissolved Solids (TDS), Pentavalent Arsenic, Hexavalent Chromium, Lead, Cadmium, Cysts, Nitrate Plus Nitrite, Nitrate and Nitrite according to NSF 58 Standard.

Overview and Site Preparation
There are eight easy steps to installing your Drinking Water system. They are as follows:
STEP 1 - Install Saddle Valve STEP 2 - Install RO Drain Connector STEP 3 - Install RO Filter Assembly STEP 4 - Install Water Storage Tank STEP 5 - Install RO Tap STEP 6 - Connect Tubing for Water Supply Line from Saddle Valve to RO System Head STEP 7 - Install RO System and Drain in Remote Location STEP 8 - Sanitize, Pressure Test, Purge System
Prepare Site For Installation
1 Before starting, close the cold water shut-off valves.
2 Tem po r ar il y p l ac e t an k a nd fi l te r a ss e mb ly in t o c ab in e t. Do ub l e c he ck po si t io n o f
items and space required for proper installation.
3 Remove tank and filter from cabinet and set aside.

STEP 1
Install Saddle Valve
Select a cold water supply line as close to the appliance as possible.
1 Turn off the water from the main water supply valve. If there are other valves leading to the area, close at least one of them.
2 Open any taps located on the selected supply line to relieve pressure in the pipe. Turn off the tap when there is no longer any air or
water escaping from the tap.
3 Clean the exterior of the supply line at the selected location. Wash plastic or stainless steel with water. Clean copper lines with
fine steel wool.
4 Turn the top handle on the saddle valve until the tip of the lancing pin, located in the center below the valve, is positioned above
the gasket.
5 Unscrew the nut holding the bottom plate on the saddle valve and remove the bottom plate.
6 Align the curved section of the top of the saddle valve with the curve of the top of the supply line. If you're installing the saddle
valve on a copper supply line, go to the next step. If you're installing the saddle valve on any type of pipe other than copper, position it so the lancing pin is toward the front of the supply line so you can drill a small hole. Mark the supply line directly below the lancing pin. Remove the saddle valve and drill a hole slightly smaller in diameter than the lancing pin. Reposition the saddle valve on the supply line and align the lancing pin with the hole drilled into the supply line.
7 Place the bottom bracket over the bottom of the supply pipe, aligning the screws with the screw holes. Tighten the nut onto the
screws so the bracket is tightened securely over the pipe.
8 Turn the top handle on the saddle valve clockwise until it will not turn anymore. There will be resistance when the lancing pin
pushes through the pipe. If the pipe was predrilled, there will not be much resistance.
9 Turn on the water supply from the main water supply valve and any other valves that were turned off.
10Check the saddle valve for leaks. Tighten the clamps if needed.
11Hold a small bucket under the supply valve and slowly turn the handle counter-clockwise to test the valve. The handle will need to
be turned many times to open the valve. If there is no water when the valve is open, check that water to the supply line was turned back on. If so, the lancing pin may not have been turned deep enough into the pipe. Repeat the lancing process by turning the handle of the valve clockwise until it is all the way in the pipe, and then open the valve again by turning it counter-clockwise.
Insert red 1/4" tubing into A RO Assembly Head inlet.
N.B - Installation kit also includes Kitchen Tap adaptor. This part is not required for installation.
N.B - Before proceeding with installation ensure your water supply is turned off.

1 Remove protective cover from back of Foam Seal N. Knock out center hole and align holes then attach to Drain Connector
front plateK.
2 Position the Drain Connector Kon the sink drain pipe above the drain trap. Allow room for drilling. Tighten Screws Land
NutsM securely.
3 Use a battery powered or properly grounded drill. Using the Drain Connector Kport as a drill guide, drill a 7/32” hole through
the wall of the drain pipe. Do NOT penetrate the opposite side of the pipe and be careful not to damage the side of the drain port fitting.
4 If you wish to install your drain in a remote location refer to page 10.
STEP 3
Install RO Filter System Assembly
The Reverse Osmosis Filter System Assembly Head A is mounted on Mounting Screws C. The Mounting ScrewsC allow you to lift the RO Filter System Assembly without any hardware removal.
1 Choose an easy-to-access area under the sink to mount the RO Filter System HeadA.
NOTE: To allow adequate space for filter changes, allow clearance of 4” - 6”below the filter to the floor. The Filter System Assembly must be mounted in a vertical position.
NOTE: Mount the Filter System Head to a solid cabinet wall or wall. If a solid surface is not available, use hollow-wall anchor bolts or toggle bolts (not included) to secure to the wall.
2 Using the Built-in Bracket on the back of the RO System Head A, mark the holes for the Mounting Screws Con the
wall surface.
3 Using a 1/8" drill bit, drill two pilot holes for the Mounting ScrewsC. Insert Mounting ScrewsC into the wall with a
Phillips screwdriver, leaving approximately 3/8" of each Mounting ScrewC exposed.
4 Hang the RO System HeadA on the Mounting ScrewsC.
Be sure that all electrical appliances and outlets are turned off at the circuit breaker before working in cabinet area.

TThe Tank Ball Valve fitting on the Water Storage Tank may need to be tightened 3-4 turns to get a good seal. Do not over tighten.
TO INSTALL WATER STORAGE TANK:
1 Apply 2-3 wraps of Plumber’s Tape H to the threads on the nipple at the top of the Water Storage Tank E
2 Locate the Tank ConnectorD. Hand tighten onto the Water Storage Tank E nipple 3-4 turns, being careful not to
cross thread or over tighten.
3 Do not connect the tube at this time. This will occur later in the assembly.
4 Place the Water Storage Tank E next to the Reverse Osmosis Filter System Assembly. The Water Storage Tank E can
be placed upright or on its side. Use provided mount stand.
STEP 5
Install RO Tap
SELECT LOCATION OF REVERSE OSMOSIS TAP MOUNTING HOLE You w il l n ee d to s el ec t th e lo ca ti on of t he R ev er se O sm os is TapP. You have three options to choose from:
Use an existing sink top hole. This may be blank. This is for the spray hose or soap dispenser
(Must be between 1-3/8” and 1-5/8” in diameter)
Drill a new hole in the sink Drill a new hole in the countertop next to the sink
1 Determine where you are going to install your RO Tap Body P . 2 Check to ensure the RO Tap BodyPwill mount flat against the mounting surface.
3 Visually review the routin g of the tubes fr om the R O System HeadA to the RO Tap BodyP. Check to ensure there is
adequate tube routing space between the RO Tap BodyP and RO System HeadA.
4 If drilling is needed, drill a 1-3/8" diameter hole in the mounting surface.
IMPORTANT: Drilling of surfaces made of stone or solid surface materials such as granite, marble, or other plastic resin or sinks made of porcelain and stainless steel may cause permanent, irreparable damage to the sink or countertop surface.

STEP 8
Sanitize, Test and Purge System
SSANITIZE THE SYSTEM Sanitizing is recommended immediately after installation of the SPECTRUM Pressure Twist-Lock (PTL) RO filter system. It’s also recommended after servicing inner parts. It is important that the person installing or servicing the system have clean hands while handling inner parts of the system. Complete the following steps to sanitize the system.
1 Make sure the water supply to the RO Filter System Assembly is off. 2 Open the Reverse Osmosis Tap. If the Water Storage Tank is not already empty, allow the water to completely empty. 3 Find the pipetteG included in package and common household bleach (5.25%). 4 Disconnect the 1/4" White Plastic TubingU from the Water Storage TankE by unscrewing the nut from the Tank ConnectorDfitting. 5 Add 3 ml. of bleach into the open end of Water Storage TankE 1/4" White Plastic TubingS. Handle bleach according to
manufacturer’s instructions.
6 Re-connect Water Storage Tank and 1/4" White Plastic TubingS to Tank ConnectorDfitting. 7 Sanitizing the RO Filter System Assembly will be completed during the pressure test and purging following steps below.
NOTE: The bleach must be completely removed from the system before drinking the RO water. See purging instructions below.
PRESSURE TEST THE SYSTEM
IMPORTANT: Complete the sanitizing procedures above before pressure testing.
1 Open the cold water supply valve to the RO Filter System Assembly. See page 3, Fig. 1 2 Open the kitchen tap. This will purge air from the plumbing system. Close kitchen tap when water runs smooth. 3 Ensure RO Tap is closed. 4 Pressure will start to build in the RO Filter System Assembly in about 2 hours. Carefully inspect all fittings and connections while the
RO Filter System Assembly builds pressure. Check for leaks and fix if any are found by ensuring all tubing is cut square and fully inserted. Also ensure tubing doesn’t have a scratch, dent, or notch at the end. If so, cut 1” off squarely and re-insert. If problems exist, refer to the troubleshooting chart.
NOTE: When the
RO Filter System Assembly
is first pressurized, water may ''discharge'' from the tap air gap hole until air is passed
from the
RO Filter System Assembly
.
PURGING THE SYSTEM
1 Open the Reverse Osmosis Tap and let water flow through the system for a 24 hour period.
NOTE: The flow rate will be very slow during the purge.
2 Close the Reverse Osmosis tap after the 24 hour purge is complete. 3 Yo ur R ev er se O sm os is sy st em i s re ad y fo r us e w he n th e pu rg e is c om pl et e.
Review the following operating features before using your Reverse Osmosis System: You w il l n ot h av e fi lt er ed w at er i mm ed ia te ly . It w il l ta ke 1-3 ho ur s to c om pl et el y fi ll t he st or ag e ta nk t o cr ea te l ib er al fl ow f ro m th e tap. The flow rate from the Reverse Osmosis system will be less than your kitchen tap. Water will run to the drain while the Re­verse Osmosis is filtering water, even when you are not using it. You may hear a water going to the drain – this is normal. Water going to the drain will automatically stop when the storage tank is at capacity.

SPECIFICATIONS – QUALIFIED SYSTEM PERFORMANCE
Because the performance of a Reverse Osmosis Membrane is highly dependent upon pressure, temperature and TDS, the following should be used for comparison purposes only.
1
Industry standards measure RO Membranes performance with no back pressure on the product water, at 60 psig (414kPa) and 25°C. Further conditions on the above are 250 ppm TDS and a 30.6% recovery rate. Production rate and TDS reduction figures are for a new Membrane that has been rinsed for 24 hours. The production rate of a new Membrane can decrease by 10% per year or more, depending upon the scaling and fouling tendencies of the Feed Water.
2
Measured at 50 psi, 25°±3°C, and 717 mg/l TDS per NSF/ANSI Standard 58.
3
Efficiency rating means the percentage of the influent water to the system that is available to the user as reverse osmosis treated water. Under operating conditions that approximate typical daily usage.
4
Recovery rating means the percentage of the influent water to the membrane portion of the system that is available to the user as reverse osmosis treated water when the system is operated without a storage tank or when the storage tank is bypassed.
Non-potable Water Sources: Do not attempt to use this product to make safe drinking water from non-potable water sources. Do not use the system on microbiologically unsafe water, or water of unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on
disinfected water that may contain filterable cysts.
Arsenic Reduction: This system shall only be used for arsenic reduction on chlorinated water supplies containing detectable residual free chlorine at the system inlet. Water systems using an inline chlorinator should provide a one minute chlorine contact time before the reverse osmosis system.
Nitrate/Nitrite Test Kit: This system is acceptable for treatment of influent concentrations of no more than 27mg/L nitrate and 3mg/L nitrite in combination measured as N. It is certified for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. This system is supplied with a nitrate/nitrite test kit. Product water should be monitored periodically according to the instructions provided with the test kit.
Product Water Testing: The Reverse Osmosis System contains a replaceable membrane cartridge critical for the effective reduction of total dissolved solids (TDS). Re­placement of the reverse osmosis membrane cartridge: The reverse osmosis system contains a replaceable membrane cartridge critical to the efficiency of the system. This membrane should be replaced every 18 months, or more often based on your local water. Only replace the reverse osmosis membrane with a part approved for use in your Reverse Osmosis system.

Reverse Osmosis System Maintenance
PRE FILTER/POST FILTER MAINTENANCE
The pre-filter and post-filters are replaceable activated carbon cartridges, model number PTL-CB They are located in the 1st and 3rd positions of the 3-stage system. It is recommended to replace the pre-filter and post-filter cartridges at least every 6 months of product water use. The pre-filter and post-filter ARE BOTH PTL-CB cartridges. You may need to replace these filters more often with a great deal of use or a high level of incoming sediment. This will protect the RO membrane from being destroyed by chlorine and plugging with sediments. You may notice a slower output of product water as the pre-filter and post­filters build up with sediments. Replace the pre-filter and post-filter cartridges when this occurs. See below for instructions.
R
R
O MEMBRANE CARTRIDGE MAINTENANCE The Reverse Osmosis membrane is a tightly wound membrane located in the center position of the 3-stage system. The membrane reduces the dissolved solids and organic matter. The life of the Reverse Osmosis mem­brane depends on the pH and hardness of the supply water. (see specifications). Membrane life is shorter with higher pH. For example, if supply water pH is under 7.5, the cartridge may last up to 18 months. However, membrane life may be as short as 6 months if the pH is as higher than 8.0. Higher pH weakens the membrane and causes pin-hole leaks. It's time to replace the Reverse Osmosis membrane when the production rate and the quality of the output water drops. The output water may begin to taste different, indicating solids and organics are passing through the Reverse Osmosis membrane. See Reverse Osmosis membrane replacement.
The Reverse Osmosis membrane output and flow rate is greatly determined by three factors: 1. Temperature of incoming water. The lower the temperature is directly proportional to the slower flow rate. All Reverse Osmosis membranes are tested at 25
o
C However, incoming water should not exceed 38oC. You need to ensure that the Reverse Osmosis system is placed in a climate controlled area and does not have
the potential to freeze. 2. TDS (total dissolved solids) present in the incoming water. More TDS requires more time for the membrane to filter and remove. Ensure incoming TDS does not exceed 2000 ppm. 3. Incoming water pressure is one of the key factors determining the flow rate of the RO membrane. Higher pressure will enable a higher flow rate. Pressure must be above 40 PSI for proper operation. You may need to install a Booster Pump or Permeate Pump if your pressure is below 40 PSI.
REVERSE OSMOSIS MEMBRANE REPLACEMENT
Complete the following steps to replace the filters.
1. Remove (turn to the left) the Twist-Lock™ pre-filter cartridge first from the system to relieve pressure on the Reverse Osmosis filter.
2. Turn the Twist-Lock
Reverse Osmosis filter to the left and remove the Reverse Osmosis filter.
3. Remove the Twist-Lock™ post-filter cartridge.
4. Discard all of the Twist-Lock™ filters in a proper manner.
5. Install new Twist-Lock™ filters in reverse order: 1) post-filter, 2) Reverse Osmosis, 3) pre-filter. Turn cartridges to the
right to secure them to the system.
6. Purge the Reverse Osmosis System per the instructions in step 8.
PRE-FILTER & POST-FILTER CARTRIDGE REPLACEMENT Complete the following steps to replace the filters.
1. Remove the Twist-Lock™ pre-filter cartridge, by turning to the left, from the system.
2. Remove the Twist-Lock™ post-filter cartridge, by turning to the left, from the system.
3. Discard the Twist-Lock™ filters in a proper manner.
4. Install new Twist-Lock™ filters in reverse order: 1) post-filter, 2) pre-filter by turning filters to the right to secure them to the system.
5. Purge the Reverse Osmosis System per the instruction in Step 8.
DRAIN FLOW RESTRICTOR
The drain flow restrictor is vital for proper operation of the Reverse Osmosis membrane. The restrictor keeps water flowing through the membrane at the proper rate. This is to ensure the system produces the best quality product water. Periodically check the restrictor assembly to be sure it is clean and unrestricted. If the drain flow assembly requires service, review Step 6 (4A). Disassemble and assemble as shown.
14
CCHECK VALVE
The check valve is vital for proper operation of the Reverse Osmosis system. The check valve ensures that the product water is flowing in the proper direction, and does not allow it to flow backwards.
AUTOMATIC SHUT-OFF The automatic shut-off conserves water when the storage tank is full by turning the system off until more product water is needed.

The water temperature is one of the key factors in the performance of the PTL-RO membrane. The higher the temperature, the higher the flow rate, and vice versa. All PTL-RO Membrane elements are tested and rated at 25oC. Ensure the PTL-RO is installed in a heated area of the home.
Incoming water has extremely high level of Total Dissolved Solids (TDS)
Incoming TDS level is one of the key factors determining the flow rate of the PTL-RO membrane. More TDS requires more time for the membrane to remove – no solution is required. Ensure incoming TDS does not exceed 2000 ppm.
Low incoming water pressure.
Incoming water pressure is one of the key factors determining the flow rate of the PTL-RO membrane. Higher pressure will enable a higher flow rate. Pressure must be above 40 PSI for proper operation. You m ay n ee d to i ns ta ll a B oo st er P ump or P erm ea te P um p if y ou r pr es su re i s below 40 psi.
Carbon pre-filter is clogged. Replace Filter with model number PTL-CB
Reverse Osmosis Membrane is fouled
Make sure incoming water pressure is within operating limits. Make sure drain line is not clogged. Correct cause of fouling or replace RO Membrane.
Air pressure in holding tank is incorrect.
Empty water from holding tank. Air pressure in valve stem should be between 5 - 7 PSI. Increase psi similar to adding air to bicycle tire.
LOW WATER PRESSURE FROM DISPENSING TAP
Possible Cause Solution
Air Pressure in Holding Tank is incorrect. TThis is the #1 reason for low flow from Reverse Osmosis Tap.
Open tap and empty water from holding tank. Shut off feed water to system and remove holding tank from under sink. (The tank is easier to work on.) Locate the air valve stem (just like on a car or bicycle tire) and add air. If there is still water in the tank, continue to add air until all the water is removed. Once all the water is removed, continue to add air and pressurize to 5 – 7 PSI. Re-install the tank under the sink, turn on the feed supply to the system and allow the tank to fill.
Carbon Post Filter is clogged. Replace Post Filter with model number PTL-CB
Heavy water use. Holding Tank is empty. Allow Holding Tank to refill.
Low Water Production. See previous section on Low Quantity of Water From Holding Tank.
Possible Cause Solution
Clogged Pre-filter.
Replace Pre-Filter with model number PTL-CB
Low incoming water pressure. Incoming water pressure must be above 40 PSI. Install a Booster Pump or Permeate Pump.
Reverse Osmosis membrane is expended.
If Membrane life is unusually short, find and correct the problem. Replace PTL-RO Membrane after 18 months.
Product water and drain water lines are reversed. Correct plumbing according to installation instructions.
No water to drain. Drain Flow Restrictor is clogged. Remove tubing from membrane drain port, cut 1” length off end of tubing and add new restrictor.
No water to drain. Air Gap Tap is clogged.
Remove tap body from tap base and disconnect air gap ¼” tubing. Ensure there are no obstructions – clear them out. Replace Air Gap Tap.Remove tap body from tap base and disconnect drain 3/8” tubing. Ensure the drain connector is properly aligned with the hole in the drain pipe. Ensure there are no obstructions – clear them out.
New Carbon Post-filter has not been rinsed completely. Drain Holding Tank twice to rinse new Carbon Post-filter.TDS.
The incoming feed water TDS has increased. An increase in feed water TDS will also give an increase in Product Water TDS.
PRODUCT WATER IS HIGH IN TOTAL DISSOLVED SOLIDS (TDS)
Possible Cause Solution
Water leak s from tap spout. Ensure the tap spout is properly seated. Repair or replace the tap.
Leaks from connection to the tap.
Check and fix compression fittings to tap. Repair or replace the tap.
Possible Cause Solution
Carbon Post Filter is exhausted. Replace Filter with model number PTL-CB
There is foreign matter in Holding Tank.
Follow the clean, flush and sanitizing procedures. Replace all filters.
Product water and Drain water lines are reversed. Correct plumbing according to installation instructions.
Dissolved gases in feed water. Pre-treat feed water to remove gasses.
Increase in Product Water TDS . See High TDS in Product Water Section.
TAS TES A ND ODOURS IN PRODUCT WATER
Possible Cause Solution
Air Gap is clogged.
Remove tap body from tap base and disconnect air gap ¼” tubing. Ensure there are no obstructions – clear them out.
Drain line is clogged.
Remove tap body from tap base and disconnect drain 3/8” tubing. Ensure the drain con­nector is properly aligned with the hole in the drain pipe. Ensure there are no obstructions – clear them out.
Drain flow rate is too high. Replace Flow Restrictor.
LEAK FROM AIR GAP HOLE IN TAP
Possible Cause Solution
Tub in g i s cr im pe d or b en t a t co nn ec ti on
Remove tubing, cut 1” off squarely – making sure to not crimp. Use a very sharp utility knife. It is not recommended to use side-cutting or diagonal-cutting pliers. Wet the tubing end and insert 5/8” until fully inserted.

Remove tubing, cut 1” off squarely – making sure to not crimp. Use a very sharp utility knife. It is not recommended to use side-cutting or diagonal-cutting pliers. Wet the tubing end and insert 5/8” until fully inserted.
Tub in g d oe s no t en te r fi tt in g a t 900 angle – not enough tubing
Re-route tubing to allow it to enter fitting at a straight 900 angle. If not enough tubing to allow, remove tubing and use a longer piece. Remove by pressing in the white collar while pulling the Plastic Tubing out with your other hand.
