Installation Instruction

Installation of the First 2 Stages Filter Housings and Cartridges

  1. Remove the protective w rap from each filter before installing.
  2. Insert the first-stage filter into the housing. Make sure the O-ring is seated in the top of the housing.
  3. Insert the second-stage filter into the housing. Make sure the black rubber cap is in the top of the housing.
  4. Insert the third-stage filter into the housing. Make sure the rubber caps on both ends are tightly attached to the filter.
  5. Carefully screw the housing onto the RO filtration system. Make sure to match them to the correct spot.
  6. Install the first-stage filter housing onto the side of the filtration system where there is a blue cap on the end.
  7. Install the second-stage filter housing onto the middle position of the filtration system
  8. Carefully screw the third-stage filter housing onto the remaining spot of the filtration system.
  9. Tighten each filter housing using the supplied wrench.
Installation of the Third Stage RO Membrane

  1. Slightly lift the housing.
  2. Remove the blue locking clip.
  3. Compress the whit e fitting and pull out the tube.
  4. Remove the cap of the housing using the supplied ro membrane wrench.
  5. Install the membrane into the housing. Make sure the end with the black O-ring is facing the cap of the housing.
  6. Tighten the cap of the housing with the supplied ro membrane wrench.
  7. Insert the tubing. Install the blue locking clip. Put the housing back into position.
  • Caution: When cutting the 4-color tubing, predetermine the length by measuring the distance between the components to be connected.
Installation of the RO Faucet

(Above the sink)

  1. Insert the two black rubber washers onto the Chrome Plate. The Black Rubber Washer 1 (the smaller one) is on the upside, while the Black Rubber Washer 2(the bigger one) is on the downside.
  2. Install the Chrome Plate and the Black Rubber Washer 3 onto t he faucet.
  3. Install the faucet into the drilled hole.

(Under the sink)

  1. Install the Black Plate.
  2. Install the Lock Washer.
  3. Install the Nut. Tighten the Nut.
  4. Install the White Collar (fitting).
  5. Install the tubing onto the faucet and make sure the tubing is tightened.
Installation of the Inlet Valve and Adapter

Select the Shut-off Valve of the right size. There are two sizes: 1/4″x 3/8″ and 1/4″ x 1/2″.
Choose what you need.

  1. Remove the nuts from the Shut-off Valve.
  2. Wrap the Teflon tape onto the Shut-off Valve.
  3. Install the Shut-off Valve into the cold water adapter.
  4. Wrap the Teflon tape onto the cold water adapter.
  5. Loosen the cold water flex line at the faucet.
  6. Wrap the Teflon tape onto the cold water flex line. Then install the Inlet Adapter.
  7. Re-install the cold water flex line onto the adapter and tighten.
  8. Slip the nut from the stop valve over the blue tubing.
  9. It is recommended that you soak the tubing into warm water for a moment.
  10. Then insert the blue tubing onto the valve. Tighten the nut.
Installation of the Anti-leak Protector

diagram

  1. Remove the 3M sticker on the bottom of the protector.
  2. Position the protector and the filtration system on the same ground level.
  3. Insert the blue tubing that is connected to the Shut-off Valve into the Anti-Leak Protector.
  4. Remove the blue lock clip from the connector of the first stage (Raw water input).
  5. Remove the blue cap. Insert the blue tubing into the connector of the first stage.
  6. Re-install the blue lock clip
  • Make sure to position the Anti-leak Protector on the floor correctly.
  • If there is any leaking from the system or water dripping on the floor, the Anti-leak Protector will cut off the water supply to the system to avoid the further leaking. Then you will need to replace the Anti-leak Protector.
Installation of the Pressure Tank

  1. Remove the blue cap on the top of the Pressure Tank.
  2. Install t he valve onto the tank and make sure it is fully tightened.
  3. Attach the red tubing to the Pressure Tank Valve.
  4. Remove the red cap from the filtration system.
  5. Attach the other end of the red tubing onto the filtration system.
Connect the Yellow Tubing of the Faucet to the Filtration System
  1. Remove the yellow cap from the last stage of the System.
  2. Connect the yellow tubing (the other end has been connected with the RO Faucet)to the filtration System .
  3. Drill a hole at a desired location on the drain pipe.
  4. Attach the sticky foam pad around the hole.
  5. Insert the black tubing into the Drain Saddle.
  6. Align the d rain saddle with the drilled hole so that the black tubing is inserted into the drilled hole.
  7. Install t he back plate.
  8. Install the nuts and tighten with a screwdriver.
  9. Remove the black cap from the water filtration system.
  10. Attach the black tubing onto the water filtration system.

Installation of the Drain Saddle

Start Using the System

  1. Turn on the cold water supply valve and the Inlet Adapter.
  2. Keep the Pressure Tank Valve off.
  3. Turn on the Faucet.
  4. Check t he system for leakage. Tighten if necessary.
  5. Keep water flowing for about 10 minutes from the Faucet. Then turn off the Faucet.
  6. It takes about 3.5 hours for the Pressure Tank to fill.
  7. When t he tank is full (you w ill hear the system stop working), turn on the Faucet until water in the Pressure Tank is completely discharged. DO NOT DRINK THE WATER OF THE FIRST TANK.
  8. Turn off the Faucet. When the system begins to work again, you can start to enjoy the purified water
  • Check for leakage daily for the first week and periodically thereafter

Maintenance

Filter Cartridges Change
  1. Shut off the water supply. Shut off the Inlet Adapter.
  2. Turn off the Tank Valve.
  3. Turn on the Faucet to release the air pressure.
  4. Change the filter cartridges.
Membrane Change
  1. The same procedure as Installation of the RO Membrane.
  2. Turn on the Manual Flushing Valve for 5 minutes.
  • To ensure a longer service life of the membrane, turn on t he Flushing Valve for 5 minutes every two months to back flush the membrane.

Trouble Shooting

PROBLEM CAUSE SOLUTION
1. Milky colored water Excessive air in the filtration system. Air in

the system is a normal occurrence when the RO system is initially installed. The milky color generally disappears within 1-2 week of normal use.

2. Noise from faucet| Air gap in the faucet and related tubing.| Turn the faucet on and let water flow for some time.
3. Slow flow to the pressure tank| It often happens when the System is starting up and the air pressure in the pressure tank is low.| Normally it takes 4-6 hours to fill the tank. Low water pressure and /or low temperature may cause the slow flow. Add pressure in the pressure tank.
4. Slow flow from the faucet/ Small capacity of water| A. Low water pressure
B. The tubing has crimps.
C. Pre-filters are blocked
D. Membrane is blocked| A. This system requires minimum 40 psi water supply pressure.
B. Keep tubing straight.
C. Replace the 3-stage pre-filters.
D. Replace the membrane.
5. Water taste or smell is not good.| A. Post carbon is depleted.
B. Membrane is depleted.
C. Pressure Tank is not clean.| A. Replace the post carbon filter.
B. Replace the membrane.
C. Drain the pressure tank and refill it overnight
6. No waste water drained| The Flow Limiting Valve| Replace the Flow limiting Valve.
7. Leaks| A. Fittings are not tightened.
B. O-ring is missing or aged.| A. Tighten fittings as necessary.
B. Contact your local dealer.
8. Leaks on the draining pipe| The hole of the Drain Saddle does not align appropriately.| Realign Drain Saddle.
