The SubTerranean™ III CBLX includes three housings, a TerraFil™ SED cartridge, a TerraFil™ CER cartridge, and a TerraFil™ CBLX cartridge.

Installation Instructions for the SubTerranean™ I CBLX<
Installation Preparation (Please refer to the installation diagram)
  1. Find the cold water pipeline beneath your sink (it is generally on the right).


  2. Shut off the cold water by turning the valve on this pipeline clockwise.


  3. Open the cold water faucet on the sink to relieve the pressure between the faucet and the shut off valve.


Fountainhead Installation

  1. Remove the accessory hole plug from the sink. If a sprayer is currently installed, this must either be disconnected and removed or another hole must be drilled through the countertop. Porcelain sinks cannot be drilled. If drilling is needed, use a variable speed drill to drill a 7/16” hole.


  2. Place the upper sink washer on the fountainhead. (White escutcheon plate)


  3. NOTE: BLACK RUBBER WASHER AS NOTED ON HARDWARE PACKAGE IS NOT NEEDED NOR INCLUDED FOR U.S. INSTALLATIONS.


  4. Place the fountainhead/washer assembly through the accessory hole from the top of your sink.


  5. From under the sink, place the lower sink washer (Black bottom washer), lock washer (Silver ring with teeth), and mounting nut (the flat, threaded brass nut supplied) on the fountainhead shaft assembly and tighten with a wrench.


  6. Take one plastic hose piece and slide the brass compression nut over the tube. Then slide the plastic delrin sleeve over the hose. (NOTE: your fountainhead hardware kit contains two plastic delrin sleeves which are used if your using our plastic hose. (ALWAYS ENSURE YOU USE PLASTIC DELRIN SLEEVES WITH PLASTIC HOSE.) Place the tube insert (either plastic or brass inserts are supplied in hardware package; unlike the delrin sleeve installations, you may use either the plastic or brass tube inserts with our supplied plastic hose.) into the hose end opening and attach to the fountainhead shaft by pushing the hose as far as it will go and then sliding the delrin sleeve and compression nut toward the shaft and tighten the compression nut with wrench. (NOTE: The fountainhead will turn as the compression nut is tightened, it is helpful to have someone brace the base of the fountainhead as tightened.)

Saddle Valve Installation

NOTE: Some local plumbing codes prohibit saddle valve installations. Please check your local code.
(NOTE: Saddle Valve CANNOT Be Installed on Plastic or Flexible Tubing)
  1. Place the saddle valve around the cold water pipeline above the shut off valve.


  2. Tighten the saddle valve to the pipeline using the clamping srew, ensuring the silver U-clamp of saddle valve is pressed flush against your cold water line.


  3. Repeat the same hose connections as with the fountainhead hose connection (Step 6-above). It is exactly the same connection.


  4. Turn the winged piercing valve nut clockwise to pierce the cold water pipe. NOTE: turning slowly and gently until you feel the pipe puncture. Then turn in the opposite direction to open saddle valve.


  5. Leave saddle valve intact with the hose connected.
System Installation
  1. Connect the fountainhead hose end to the “Out”-going quick-connect fitting on the housing assembly. “Out”-going quick connect should be the right-hand side on the base of the housing, to ensure “Out”-going quick connect check on the bottom of the base for the “Out”-side. (NOTE: be sure to push hose into quick-connect fitting until it does not go any further. Pull on the hose to ensure hose has locked into place.)


  2. Connect the saddle valve hose to the “ln”-coming quick-connect fitting of the housing assembly. “In”-coming quick connect should be the left-hand side on the base of the housing, to ensure “In”-coming quick connect check on the bottom of the base for the “In”-side. (NOTE: The saddle valve remains clamped to your cold water pipe after you puncture the line. There is a black washer designed into the C-style saddle valve, which will give a tight seal around the hole in the cold water pipe.)


  3. Open the cold water valve (turn it counter-clockwise) slightly, and check ALL the connections for leaks. Do not apply full water pressure before checking the connections.


  4. After the connections have been secured, open the cold water valve completely.

  5. During initial use, water and airbursts will come out of the fountainhead until the SubTerranean™ fills up with water. Flush the system for 7 to 10 minutes before use.
Changing the CBLX cartridge.
  1. Shut off the cold water by turning your cold water shut off valve clockwise.


  2. Open the cold water faucet on the sink and depress your fountainhead to drain any water in the lines. This will relieve the pressure between the faucet and fountainhead and the shut off valve. Make certain that the water is turned off. Note: There will be water remaining in the housing.


  3. Place a bucket or basin under the housing. Unscrew the housing from the base. Remove the cartridge and save for the Warranty and Global Recycling Program™


  4. Rinse out the housing dome and base with a disinfectant, i.e. dishwashing liquid, hand soap, etc. and scrub thoroughly with a brush or sponge. Rinse thoroughly.


  5. Remove 0-ring from the groove in the housing and wipe the groove and 0-ring clean. After cleaning the 0-ring and groove, relubricate the 0-ring with Vaseline, Vegelatum, or margarine. Then place the 0-ring back in the groove and with two fingers wipe or press it down into the groove making sure the 0-ring is seated flatly in the groove. NOTE: This step is important to ensure proper filter seal. Make certain the 0-ring is seated level in the groove. In addition, enough lubricate i.e., Vaseline, Vegelatum or margarine must be applied to the 0-ring or leakage could occur at the housing dome/base connection.


  6. Place the cartridge in the housing (following the TerraFil™ CBLX installation instructions).


  7. Tighten the housing until the housing dome is firmly seated upon the base.


  8. Open the cold water valve (turn it counter-clockwise) slightly, and check the connections for leaks.


  9. Do not apply full water pressure before checking the connections.


  10. After the connections have been secured, open the cold water valve completely.


  11. During initial use, water and air bursts will come out of the fountainhead until the SubTerranean fills up with water. Flush the system for 7 to 10 minutes before use.
NOTE: Every 400 US Gallons or when the water flow decreases, the TerraFil CBLX should be replaced. Call toll free: 1-800-800-TERRA, or visit www.terraflo.com to place an order for a new replacement cartridge. After several hours of non-use, for best results, flush the system for at least 30 to 60 seconds before drawing water. After prolonged periods of non-use (such as during a vacation) the system should be flushed thoroughly. Let the water run for 7 to 10 minutes.

Caution: The rubber 0-ring provides the watertight seal between the base and the dome. It is important that the 0-ring be properly seated in the groove in the housing or a water leak could occur.

Caution: This filter must be protected from freezing. Failure to do so may result in cracking of the filter and/or water leakage.

Caution:
Do not use where water is microbiologically unsafe or with water of unknown quality without adequate disinfection before the system. This system is for use on municipally treated or potable well water only.

NOTE: These systems are for cold water use only.

Bracket and Filter Installation for
SubTerranean™ II and III systems

  1. With the supplied screws, mount the bracket assembly to the back or side of your base cabinet below the sink. Be sure to leave enough room below the bracket assembly to allow for cartridge replacement.


  2. Connect one hose to the “out”-going ¼” Quick Release fitting on the housing assembly. The other end of this hose attaches to the compression adapter on the bottom of the fountainhead using the ferrule and compression nut.


  3. Connect the other hose to the “in “-coming ¼”quick release fitting of the housing assembly. The other end of this hose attaches to the saddle valve using the ferrule and compression nut.


  4. Turn the winged piercing valve nut on the saddle valve counter clockwise to open the water flow to the filter unit.


  5. Open the cold water valve (turn it counter-clockwise) slightly, and check the connections for leaks.


  6. Do not apply full water pressure before checking the connections.


  7. After the connections have been secured, open the cold water valve completely.


  8. During initial use, water and air bursts will come out of the fountainhead until the housings fill up with water. Flush the system for one minute before use.
