Under Sink Location
Both the Reverse Osmosis Assembly and fresh water storage tank will need to be installed in a kitchen or bathroom sink cabinet. The reverse osmosis waste water line will need to be hard connected to a sink drain-line by using the drain saddle adapter enclosed in the package.
Note: The drain saddle adapter will need to attach above the sink drain P-Trap to drainwater from the reverse osmosis system. Review the following schematic, Figure 1, for more information.
Typical Under Sink Installation Layout

How to Cut and Connect the PE Tubes

Review to the following instructions before connecting the tubes to their dedicated fittings. Failure to follow these instructions may lead to future leaks. See Figure 2 for more information.

How to Cut the PE Tube

1. Carefully use a tube-cutter or knife blade to cut the end of tubing. Always cut the tubing square.
2. Inspect the tube up to 1” from the end to be sure there are no nicks, scratches or other rough spots. If needed, cut the tubing again.

How to Connect the Tubes

1. You will notice that the PE tubes have black marks close to the end of the tube. The black mark is to help assist you in knowing if the PE tube is seated or fully engaged into the fitting.
2. Push tubing through collet until it engages the O-Ring. See Figure 3.
3. Continue pushing until the tube bottoms out against the back of the fitting. See Figure 4.
4. Do not stop pushing when the tube engages the O-Ring. Failure to follow these instructions may lead to future leaks.

Installation Instructions

STEP 1 – Install Cold Water Supply Fitting
Check and comply with your local plumbing codes before you start installation. Refer to the Specifications and Dimensions page 3 for supply water requirements. The Water Supply Fitting can be adapted to a 3/8” or ½” supply line with the enclosed adapter. See Figure 4 for more details.

INSTALL THE COLD WATER SUPPLY FITTING

1. As shown in Figure 4, the hot and cold water supply shut-off valve can be located under the kitchen or bathroom sink. Close both valves and open the sink faucet to release any pressure in the water supply lines. Make sure the sink faucet water has stopped flowing before proceeding to the next step.
   Note: Typically, the cold-water supply shut-off valve is located on the right side. However, in order to ensure this, please keep the hot water on for two minutes.Feel the two hoses with your palm. The hot water supply riser hose should be warm, and the other pipe which is cold should be the cold-water supply pipe.

2. Before disconnecting the cold-water supply line, have a bucket and towel ready to capture any water left-over in the water supply line.

3. Disconnect the existing cold-water supply line from the water shutoff valve and water faucet supply line.

4. Inspect the water supply fittings to make sure that thegasket is inside the female threaded portion of the fitting.

5. Before installing the water supply fitting onto thecold-water shutoff valve, be sure to wrap the threads withthread-tape. Be careful not to cross thread or over-tighten.

6. Connect the existing cold-water line to the male threaded portion of the water supply fitting and hand-tighten. Be careful not to cross thread or over-tighten. Once threaded properly, tighten with an adjustable wrench.

7. When the water supply fitting is connected to the cold-water supply, make sure the water shutoff valve is in the closed position, refer to Figure 5.

8. Hold off on attaching the “white” PE tube to the water supply fitting, this water connection will be made in Step 6 – Connect PE Tube.

STEP 2 – Install Drain Saddle Adapter
The drain saddle adapter is needed for the drain water produced from the Reverse Osmosis Filter. Please make sure the drain saddle adapter is located above the P-trap, as shown in Figure 6 and do not connect or install the drain saddle adapter on a drain-line coming from a garbage disposal.

INSTALL DRAIN ADAPTOR
The drain saddle adapter is included with your RO system. The drain saddle adapter will fit around a standard 1-1/2” drain pipe. Shown in Figures 6, 7, and 8, you will install the drain saddle adapter above the P-trap. Note: If your sink is equipped with a garbage disposal drain, do not install the drain saddle adaptor to this drain point. Please inspect the drain pipe for corrosion and replace, if necessary.

1. Test fit the drain saddle adaptor around the sink drain to make sure will it fit properly. The drain saddle adaptor should be installed approximately 6-inches above the P-trap, see Figure 6.
   

2. Make sure the quick connect fitting on the drain saddle adapter is installed in the direction toward the RO system for ease of installation of the PE tube.

3. With a pencil, carefully scribe the drain pipe to mark the location of where the PE tube will connect. See Figure 7 for location of quick connect fitting.
   

4. After making your mark on the drain tube, remove drain saddle adaptor and drill a 3/8” diameter hole in the drain pipe. Note: Do not drill with the drain saddle adaptor attached, it may damage the quick connect fitting. Only drill through one side of the drain pipe.

5. Remove any loose plastic and line up the drain saddle adapter with the hole you just drilled.

6. Place the two halves of the drain saddle adaptor back onto the drain pipe. Now fasten the nuts and screws.  Tighten both sides equally to secure the drain saddleadaptor onto the drain pipe. Do not overtighten. See Figure 8.

7. Hold off on connecting the “RED” PE tube to the quick connect fitting on the drain saddle adapter, this water connection will be made in Step 6 – Connect PE Tube.

STEP 3 – Install Reverse Osmosis Faucet
You will need to select a location to install the reverse osmosis faucet. In most kitchen installations, the spray hose or soap dispenser is removed and replaced with the RO faucet.
The hole size must be 1-1/4” in diameter. If a spray hose or soap dispenser is not available, you will need to either drill a hole in the sink or a new hole in the countertop, next to the sink.
Note:
When installing the RO faucet in the sink or countertop, please consider hiring a professional to drill the holes. Drilling surfaces made of stone or solid surface materials such as granite, marble or plastic resin product, or sinks made of porcelain or stainless steel may cause permanent damage or irreparable damage to the sink or countertop surface.

INSTALL REVERSE OSMOSIS FAUCET

1. The RO faucet is included with your RO System. Locate and organize the RO installation parts, see Figure 9 for more details on assembly.
2. Referring to Figure 9, You will need to install the part in the order shown, Stainless Steel Washer; Thin Black Washer. Slide both onto the base of the faucet screw rod. The thin rubber washer should be sandwiched in between the faucet top and stainless steel washer.
3. Remove the red protective cap from the end of the RO faucet screw rod.
4. Now install the RO faucet through the mounting hole.
5. Under the cabinet install the following components in this order: Reference Figure 9: Thick Black Rubber Washer; Metal Serrated Washer; Nut. In the order shown above, slide onto the base of the RO faucet screw rod.
6. Hand tighten the nut to threaded rod of the RO faucet until the faucet cannot move freely. Check the RO faucet to make sure the stainless steel washer and thin black washer is centered under the faucet. Once aligned, tighten the nut with an adjustable wrench.
7. The RO Faucet Base Connector is included with your RO System. Install this connector to the base of the faucet. Push connector onto faucet base until the connector bottoms out, see Figure 9.
8. You will attach the “BLUE” PE tube to the base of the faucet quick connect connector.
9. After you have inserted the blue PE tube into the connector, insert the blue PE Tube Lock Clips into the quick connector end. See Figure 10 for order of installation.

STEP 4 – Install Filters
Each filter is individually wrapped in a plastic protective coating, remove and safely discard the plastic before installing filter into filter housing. You will find 6-black rubber O-Rings in a sealed zip-lock back. These will be installed onto the filter housing, see
Figure 11.
Note: The RO filter will NOT be installed at this time. We will install the RO filter after the RO system is flushed with fresh water. Refer to First Time Use – Flushing the Filters for more information.
INSTALL THE VERTICAL FILTERS

1. Referring to Figure 11, you will install two O-Rings on each filter housing. Install one O-Ring seal on the top outside grove of the filter housing. Gently slide the O-Ring down the outside filter housing surface until the O-Ring is seated into the upper grove. The second O-Ring lays on the top inside end-face of the filter housing. Note: applying a light amount of food-grade silicone jelly may be used to help the O-Ring seal better.
2. When placing the filter cartridge into its housing, make sure that the inner hole of the filter cartridge is aligned with the cylindrical boss at the bottom of the filter housing. If not aligned properly, the water filter will leak.
3. Screw the filter housing assembly, with filters installed, to the filter head. Turn the filter housing in a clockwise direction. Once snug to the filter head, use the Filter Housing Wrench to tighten it another ¼ to ½ of a turn. See Figure 12.

8. Faucet

STEP 5 – Install Fresh Water Storage Tank & Reverse Osmosis System
Your RO system utilizes a pressurized tank to store purified water. Because the Reverse Osmosis process is slow, the fresh water storage tank is pressurized to improve the water flow at the faucet. After water is dispensed from the RO water faucet, the storage tank will refill and repressurize, therefore you may hear water flowing through the filtration system when not in use. The process of purifying water is slow, so water may run for a brief period of time depending on how much water was dispensed. Note: Be careful not to overtighten the Shutoff Valve.

Install the Pressure Tank

1. The Fresh Water Tank Shutoff valve is included with your RO System. See Figure 14 or the following illustrations.
2. The shutoff valve on the supply tank will need to be air-tight.
3. Apply Tape Seal to the threads of the at the top of the tank.
4. Tighten the shutoff valve clockwise on the fresh water tank connecting screw, be careful not to cross-thread or overtighten.
5. Connect the “white” PE Tube to the quick connector of the Fresh Water Tank Connector. After you have inserted the whitePE tube into the connector, insert the blue PE Tube Lock Clipsinto the quick connector end.
6. Place the storage tank next to the Reverse Osmosis system.Place the tank upright.

STEP 6 – Connect PE Tubing
Now is time to connect the PE the white, blue and red PE tubes to the RO filtration system. Referring to Figures 15, 16, 17 & 18, you will see that the water connections are clearly marked. NOTE: Please read Step 6 carefully. When all PE tubes are installed, please inspect all connecting tubes of the unit, make sure no tubes are bent and are pushed all the way into the water connections.

Maintenance and How To Section

First Time Use – Flushing Stage 1 – 3 Filters
Inspect all connecting tubes of the unit, make sure no tubes are bent. Before using the machine, the first 3-filters (stage 1, 2 & 3) will need to be flushed with fresh water for 3-minutes. This will prevent carbon particles in the activated carbon filter elements from
entering the RO filter element. Note: When you start to dispense water from the RO faucet, you will notice the water output will be cloudy at first and then become clear. Depending on your water pressure, it may take a little longer to flush out all carbon particles. Flushing the first 3-filters will significantly improve the life of your RO filter element. When the flushing procedure is complete, you will then install the RO filter. See the following page for more details on, “How to Install the RO Filter”.

Flushing Stage 1 – 3 Filter, Steps
Please make sure the person performing this process has clean hands while handling or servicing the inner parts of the filtration system.

1. To begin the flushing process, you will need to make sure the RO fresh water storage tank valve, letter F in the above picture, is in the closed position. Note: Please make sure the RO filter is not installed during the flushing process.

2. You will need to open three water valves: 1) open the inlet water supply fitting, letter A in the above picture, and 2) the sink main water inlet valve and 3) the RO faucet.

3. You should start to hear water running through the RO system. Note: you may hear strange noises and air passing through the RO system, this is normal.

4. Water will start to flow out from the RO faucet, slowly at first and then once pressure builds the water will start to flow faster. Note: Make sure the RO faucet is pointed to sink basin, water will start to flow through the filters.

5. Flush the unit for three-minutes until the water becomes clear.
   Note: The water will appear cloudy and then will start to clear up. If after three-minutes the water is still cloudy, continue running water.

6. When the water becomes clear, close the inlet water supply fitting, letter A in the above picture. You will need to install the RO filter. Note: Before removing the RO cap, you will need abucket and towel to capture any water that may be in the RO filter housing. Please make sure all water is removed from the RO filter housing.

HOW TO INSTALL THE RO FILTER

1. Locate the RO Filter by Referring to Figure 20.

2. To install the RO Filter, first remove the blue PE Tube Locking Clipand white PE tube that is connected to the right side of the RO filter housing.
   How to Connect and Disconnect the Tubes
   • The white PE tube is inserted into a quick connect housing.
   • To remove the white PE tube, remove the blue PE tube locking clip, and press inward on the Collet (dark grey ring) that the PE tube is inserted into.
   • Gently pull out the white PE tube from the water connector. See illustration to the right for details.

3. Remove the filter housing cap by unscrewing counterclockwise. Inspect the underside of the housing cap to make sure there is an O-Ring installed. Inspect the filter housing to make sure there is an O-Ring installed. See Figure 21.

4. NOTE: For your safety, the RO system is wet tested prior to shipment, so you may notice some water drops are still inside the filter housing.

5. Reference Figure 22, install the RO filter by inserting the “small head” end of the membrane firmly into the housing.
   NOTE: one end of the RO membrane has a thick-rubber gasket, this should be inserted towards the filter-cap end.

6. Before twisting the housing cap back on, make sure the O-Ring is seated at the end of the membrane housing, which is very important to avoid leaking and damage to the O-Ring.

7. Place the membrane housing cap back and pre-tighten it with hand, then tighten it with the housing wrench. Do not over tighten.

8. Reconnect the white PE tube to the quick connect fitting and install the blue PE tube locking clip.

9. Please make sure the white PE tube is fully engaged into quick connect fitting or water will leak from the fitting.

Flushing All Filters in System
Now that Stage 1 – 3 filter are flushed, we will now need to flush out the RO filter membrane. Please read through the following steps.

1. With the RO filter installed, open the RO fresh water storage tank water valve, turn on RO drinking faucet, open the water inlet valve slowly check for water leaks. If so, check for the following:
   • The PE water tube is not completely inserted into the quick connector.
   • O-Ring in the filter housing is not in the proper position or twisted.
   • Filter Housing/cover is not properly tightened or not aligned with threads.

2. Please close the RO fresh water storage tank valve, RO water will slowly drip out of the drinking faucet, keep the drinking faucet draining for at least 15-minutes to flush the whole filter element system.
   NOTE: It is important that the RO Fresh Water Storage Tank water valve is in the CLOSED position during the 15-minute flush process.

3. After 15-minutes, please close the RO faucet and open the shut off valve of the RO fresh water storage tank. The RO fresh water storage tank will begin to fill with fresh RO water.
   Note: This process may take 1-2 hours, depending on your water temperature (40F-100F, the higher the temperature, the faster the speed) and source water TDS (max. 750ppm, the lower the TDS, the faster the speed). After the storage tank is full, the unit
   will automatically shut down.

4. After the storage tank is full, turn on the RO faucet to completely drain the first storage tank to empty, when no water comes out from the RO faucet, it means the tank is emptied. Then turn off the RO faucet to let the system start producing RO water again.

5. NOTE: It is very important to check for water leaks every day for the first two weeks after installation to ensure the normal operation of the system. Congratulations, you have successfully installed your Comfee Reverse Osmosis Water Filtration System!

Replacement of Filter Elements
Your Comfee CMP10 Reverse Osmosis filtration system is designed for low maintenance. Replacement of 1st to 3rd-Stage Filter Element
If the flow or quality reduction is found, it should be replaced every 6 months or earlier. The frequency of replacement depends on your water consumption and the quality of source water. In order to protect the reverse osmosis membrane from chlorine and other harmful contaminants, it is necessary to replace the filter element according to its service life. How to Replace 1st to 3rd-Stage Filter Elements:
Please be careful when replacing the filters. To help reduce the water pressure, it is recommended to turn off the main water supply and close the RO fresh water inlet valve.
When both valves are off, open the RO faucet to release any pressure. You will need your filter housing wrench for this filter removal process.

1. Close the sink main water inlet valve, the RO water inlet valve and the RO fresh water inlet valve on the RO fresh water storage tank.
2. Please open the RO water faucet to reduce the system pressure, and place a towel under the machine. It is a good idea to have a bucket handy to dump the water in the filter housing. Note: When you remove the water filter housing, water will be present in the filter housing. Carefully tip the filter housing into your bucket to empty the water.
3. If the unit is installed under the sink with enough space or hung on the wall, the filter housing may be directly unscrewed to replace the filter element. Or, you will need to remove the unit and replace the filter element. Be careful for all the tubing connections when removing the machine.
4. Unscrew the housing of the filter element counterclockwise with the filter housing wrench.
   Note: For more information on how to install the filters, Refer to Step 4 – Install Filters.
   Replacement of the 4th Reverse Osmosis Filter Element
   Generally, the RO membrane is replaced every 2-3 years, and the TDS value is checked at least once a month to monitor the performance of the system. Under normal circumstances, the desalination rate of the unit will be greater than 90%.

How To Replace The RO Membrane Filter Element

1. Your Reverse Osmosis membrane usually has a useful life of about 2-3 years. The useful life of filter membrane depends on the quality of source water, household water consumption and the frequency of replacing 1st to 3rd filter element.
   NOTE: In order to ensure the performance of the system and the purity of water, please replace the 1st to 3rd filter element as planned.

2. Please open the RO water faucet to reduce the system pressure, and place a towel under the machine. It is a good idea to have a bucket handy to dump the water in the filter housing.
   Note: When you unscrew the filter cap from the RO membrane filter housing, water will be present in the filter housing. Place a water bucket close to the RO filter cap to capture any water which may spill.

3. Remove the PE tube from the RO filter housing and unscrew the filter housing counterclockwise with the housing wrench.

4. It may be necessary to remove the RO filter membrane with a pair of pliers. Carefully pull on the filter end to slide the filter out of the filter housing.
   Note: The RO filter has a very tight fitting inside the RO filter housing. Pulling out the RO filter membrane can be difficult.

5. Inspect the inside of the RO filter housing. Please rinse the inside of RO filter housing thoroughly with warm soapy water. Use a small amount of dishwasher detergent to clean the inside of the RO filter housing.

6. Open the vacuum-tight package of the new reverse osmosis membrane, remove the RO membrane and insert it into the filter housing.
   Note: Please try to avoid touching the filtermembrane with your bare hands. Using a paper towel to wrap around the end of the filter to help you install thefilter.

7. Inspect the filter cap O-Ring and internal O-Ring. Make sure both are present and installed correctly.
   Note: We recommend replacing the O-Ring every 3-years to prevent water leaks caused by an aging O-Ring.

8. Install the RO membrane housing cap and pre-tighten it by hand, and then tighten it by 1/4-½ turns with a housing wrench, without over-tightening.

Replacement of the 5th Stage Post Carbon Filter Element
Note: Please replace the post carbon filter element every 12 months. To help you remember when the filter was installed, mark the outside of the filter housing with the installation date.

1. Remove all tubes connected to the post carbon filter housing.
2. Replace the whole filter (including the housing) with a new one, then reconnect the tubes.
