6 Month System Maintenance

Items needed:

  • Stage 1 - Sediment Filter (P/N: 104017)
  • Stage 2 & 3 - Carbon Block Filter (P/N: 101009-White End Caps)

Note: The filter wrench pictured (P/N: 164003) may be purchased from Watts Premier to aid with twisting off filter housings (not required)

Step 1:
Turn off the incoming water supply to the RO at the feed water valve. (Follow the green tube away from the RO system to find the valve.)

Step 2:
Open the RO Faucet and allow water to drain from the tank until it is completely empty.

Note: Water may be saved in a container for drinking or to rinse system parts.

Step 3:
Let system sit for one minute after the tank is empty to let the system depressurize before attempting to remove filter housings.

Step 4:
For more leverage you may leave the RO module attached to wall of cabinet. If you are unable to access the module while it is mounted, remove it prior to changing filters. Starting with the closest housing
(Stage 1), remove it by turning it clockwise (left), empty water, then discard filter. Continue on to the 2nd housing (Stage 2) and 3rd housing (Stage 3).

Step 5:
Clean the filter housings (bowls) with a mild soap solution and rinse with water. Check O-rings and lubricate with water soluble lubricant. KY Jelly® or other water based lubricants may be used. Petroleum based lubricants (such as Vaseline®) must not be used.

Caution:
Before re-installing the filter bowls back on to the system, check O-rings to make sure they are still in place.

Step 6:
Insert the new sediment filter (cloth like appearance) into the 1st filter housing which is the one closest to the side with tubing connections
and re-install housing.

Step 7:
Insert the new Carbon Block filter (White End Caps) into the second and third stage housing and re-install housings.

Step 8:
Turn water on to the unit at the adapt-a-valve.

Step 9:
Open the RO faucet and leave it open until water begins to trickle out (it will come out slowly).

Step 10:
Close the RO faucet allowing the storage tank to fill with water. It may take 3 to 6 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and
water pressure.

 

Annual Maintenance

Items Needed:

  • Stage 1 - Sediment Filter (P/N: 104017)
  • Stage 2 & 3 - Carbon Block Filter (P/N: 101009-White end caps)
  • Stage 5 - 10” Final Polishing Filter (P/N: 100017)
  • 1/2 Cup of hydrogen peroxide or common household bleach

Note: Sanitizing of unit is recommended.

Step 1:
Perform steps 1 through 5 in the 6 Month System Maintenance .

Note: If not sanitizing the system skip to step 8.

Step 2:
Remove the RO membrane from its housing and rest in a clean sanitary place. (Refer to “Membrane Replacement” section for directions on removing the membrane). Replace cap onto empty membrane housing and re-connect green tubing.

Step 3:
Leaving the filters out, replace stage 2 and 3 empty filter housings (hand tight) onto unit. Measure & pour either 1/2 cup of hydrogen peroxide or common household bleach into the
1st filter housing (Stage 1) and hand tighten onto unit

Step 4:
With the RO faucet in the closed position turn on the incoming water supply to the system by turning the adapt-a-valve counter clockwise. Wait 1 minute for the unit to pressurize. Turn on the RO faucet and let the water run for 30 seconds. Turn off the RO faucet and let the unit rest for 2 minutes. Finally, open the RO faucet and let the water run for 5 more minutes

Step 5:
Turn off the incoming water supply to the system by turning the adapt-a-valve clockwise until it stops. Keep the RO faucet open until the storage tank is completely drained.

Step 6:
Open the membrane housing and re-install the RO membrane while making sure not to kink the O-rings. (Refer to “Membrane Replacement” section on page 15 for directions on installing the membrane). Tighten the cap back on the housing and reconnect green tubing

Step 7:
Remove filter housings Stage 1, 2 and 3 and empty of water.

Caution: Before re-installing the filter bowls back on to the system , check O-rings to make sure they are still in place and lubricate with water soluble lubricant.  If the O-rings appear dry, cracked, or damaged in any way, we recommend replacing them.  They can be purchased from our website (P/N 560046)

Step 8:
Insert the new sediment filter (cloth like appearance) into the 1st filter housing which is the one on the water inlet side (green tubing from the adapt-a-valve) of the RO system and re-install housing.

Step 9:
Insert the new Carbon Block filter (White End Caps) into the 2nd and 3rd housing and re-install housing

Step 10:
The final in-line filter (Stage 5) is located on the blue tube between the RO Module and the RO faucet. Remove it by loosening the compression fittings on both ends. Remove the 3/8” fitting from old filter, re-apply Teflon tape if needed and install on the new in-line filter. Install new in-line filter on to the blue tube

Note: The arrow on the final filter must be pointing towards the RO faucet / away from the RO Module.

Tip: This is a good time to check the air pressure in your storage tank. 

Step 11:
Follow Steps 8 through 10 in the Six Month System Maintenance for startup directions.

 

Membrane Replacement

Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions and the amount the RO system is used. This reverse osmosis membrane is critical for effective reduction of total dissolved solids (TDS). The product water should be tested periodically to verify that the system is performing satisfactorily. Normally, a membrane would be replaced during a semiannual or annual filter change. However, if at any time you notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could be time to replace the membrane. Watts Premier recommends replacing the membrane when TDS reduction falls below 75%.

Note:
A water sample may be sent to Watts Premier for a free diagnosis of your membranes performance. To send a water sample, use two (2) clean containers and fill ½ cup of tap water in one container and ½ cup of reverse osmosis water in 2nd container. Clearly label each sample. Send the samples to the address listed on the cover of this manual attention “Water Samples”. Watts Premier will test the water and mail or call you with the results.

Step 1:
Turn off the incoming water supply to the RO by turning the needle valve on the adapt-a-valve clockwise until it stops. (Follow the green tube away from the RO system to find the adapt-a-valve.)

Step 2:
Open the RO Faucet and allow water to drain from the tank until it is completely empty

Step 3:
Remove the horizontal membrane housing on top of the unit by turning it counter clockwise to loosen.

Step 4:
Pull firmly on the yellow RO membrane to remove it from the housing and discard

Step 5:
Lubricate the O-rings on the new membrane with a water soluble lubricant such as KY Jelly ®. Insert the end with the two black O-rings into the cap. Twist the membrane as you push it firmly into the manifold.

Caution: Before re-installing the membrane housing back on to the system, check O-ring on the housing to make it is still in place and lubricate with water soluble lubricant.

Step 6:
Replace the membrane housing onto the cap by turning clockwise. Tighten securely

Step 7:
Follow Start up instructions below.

 

Start Up Instructions

Step 1:
Turn on the incoming cold water at the angle stop valve and the Adapt-a-Valve. Check the system for leaks and tighten any fittings as necessary. (Check frequently over the next 24 hours to ensure

Note:
If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker) until flushing (Step 4) is complete and the tank has been allowed to fill completely. Connection from the RO to the ice maker system should have an in-line valve installed before the ice maker so it can easily be closed to prevent water flowing to the ice maker during start up and periodic maintenance. Your storage tank must be allowed to fill up fully in order for the ice maker system to work properly.

Step 2:
Open the RO faucet and leave it open until water begins to trickle out (this may take a few minutes and the water will come out slowly).

Step 3:
Close the RO faucet allowing the storage tank to fill with water. It may take 3 to 6 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and water pressure

Note: During the fill period you may hear water trickling which is a normal occurrence

Step 4:
After the storage tank has filled (the water trickling has stopped), open the RO Faucet to flush the tank completely. You will know that the tank is empty when the flow rate from the RO faucet is down to a trickle. Repeat this step two more times. The fourth tank can be used for drinking.

The flushing process should take about a day to complete.

Note: Flushing of the tank 3 times is only necessary during the initial startup and after replacing the membrane.

 

Check the Air Pressure in the Tank

Important: Check air pressure only when tank is empty of water!

Check air pressure in the storage tank when you notice a decrease in available water from the RO system. Air can be added with a bicycle pump using the schrader valve that is located on the lower side of the tank behind the blue plastic cap


Step 1:
Turn off the incoming water supply to the RO.

Step 2:
Open the RO Faucet and allow water to drain from the tank until it is completely empty.

Tip: When water from the RO faucet slows to a trickle, with the faucet still in the open position, you may add air to the tank to purge any left over water, this will ensure that the tank is completely empty.

Step 3:
Once all water in the tank is purged, check air pressure using an air pressure gauge, it should read between 5 - 7 PSI. (Digital air pressure gauge is recommended)

Step 4:
Follow startup procedure
