Undersink Units
(Models 201 & 203)

 

WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the unit.

Installation

  1. Turn off cold water supply valve and turn on cold water to release pressure.
  2. Clamp saddle valve to cold water line (see Diagram 1)
  3. Choose the best location for the provided faucet and install. (A hole may need to be drilled through the sink or countertop)
  4. Set filter under the counter and close to the saddle valve and faucet.
  5. Cut the amount of tubing needed to connect the saddle valve to the inlet as marked on the unit. Make sure tubing is long enough to make any needed turns or move the unit freely. Cut the tubing to be placed from the outlet of the unit to the faucet.
  6. Attach INLET TUBING
    a)  Slide compression nut from saddle valve onto hose. If the model being installed has 3/8" tubing, use one of the 3/8" adapters provided.
    b)  Slide delrin sleeve onto tubing so that its smaller diameter points out towards the end of the tubing.
    c)  Slip brass insert into the end of tubing to be attached.
    d)  Slip tubing onto fitting at the saddle valve and tighten the nut.
    e)  Attach other end of INLET TUBING to the inlet by simply pushing it into the opening as far as it will go.
    f)  If the undersink unit is provided with a pressure reducing valve, cut the INLET TUBING and attach the valve to the tubing. Use the sleeves and inserts provided.
    g)  If unit is provided with a Pre-Filter, connect INLET TUBING to pre-filter after prefilter is mounted on a suitable surface (bracket and screws are provided).
  7. Attaching OUTLET TUBING
    a) Slide brass nut from faucet onto tubing. If the model being installed has 3/8" tubing, use one of the 3/8" adapters provided.
    b) Repeat steps 6b) and 6c).
    c) Slip tubing onto fitting at the faucet and tighten the nut.
    d) Attach other end of OUTLET TUBING to the filter by simply pushing it into the opening as far as it will go.
  8. Check to be sure all connections are tightened.
  9. Turn faucet handle to the on (upward) position.
  10. Slowly turn piercing valve all the way until copper line is pierced and slowly turn valve back until you feel water is beginning to run through the filter. Always make sure there are no leaks at the fittings. Turn valve open until desired flow is reached.
  11. If there are no leaks continue running water until water is clear (5 to 10 minutes). The filter is now ready for use.

Note:

  • The unit is designed for use with COLD WATER ONLY.
  • The recommended flow rate for best results is 1/2 to 1 gallon per minute. Increased flow will reduce the unit's effectiveness.
HELPFUL HINTS:An activated carbon cartridge (Taste/Odor) may contain a small amount of carbon fines (very black powder) and a new cartridge, after installation, should be flushed with sufficient water to remove the fines before using the water.

 

Maintenance

PLEASE CHANGE FILTER CARTRIDGE REGULARLY BEFORE PROBLEMS APPEAR.

A reduction in water flow or a change in the color or taste of the water should be considered an indication that the filter is near the end of its useful life. The actual length of time the main filter will effectively remove chlorine and other contaminants will mostly depend on the original quality of the source water, pH and amount of water used. However, the sediment cartridge in the pre-filter has to be changed when its colour changes from snow white to yellowish brown, or when the flow is slow.

How to change filter cartridges?

  1. Turn on the faucet where filtered water comes out.
  2. Turn off water supply to filter and wait for the water and air in the faucet to drain out completely.
  3. Unscrew sump in clockwise direction (using spanner wrench if necessary).
    NOTE: When opening filter housing to change cartridge, it is common for O-ring/Gasket to lift out of housing and stick to cap.
    NOTE: If the housing cannot be opened even with a spanner wrench, carefully depress pressure release button (if present) to relieve pressure in filter housing and then try with the spanner wrench again.
  4. Remove used cartridge and discard. Clean and rinse out housing thoroughly and fill about 1/3 full with water.
  5. Remove O-ring/Gasket from sump carefully and wipe groove and O-ring/Gasket clean. Lubricate O-ring/ Gasket with a coating of clean petroleum jelly (Vaseline). Place O-ring /Gasket back in place and press O-ring down into the groove with two fingers (or place gasket on rim of sump).
    NOTE: This step is important to ensure proper filter seal. Make sure the O-ring is seated level in the groove (or gasket is on rim of sump).
    CAUTION: If O-ring/ Gasket appears damaged or crimped it should be replaced at this time.
  6. Insert a new cartridge into the sump making sure that it slips down over the sump standpipe.
  7. Screw the sump onto the cap and hand tighten (use one hand if possible to avoid over-tightening). DO NOT OVER-TIGHTEN. NEVER TIGHTEN THE SUMP WITH A SPANNER WRENCH. Make sure cartridge slips over the cap standpipe.
  8. Turn on the water supply slowly to allow housing to fill with water.
  9. Depress the pressure release button (if present) to release trapped air from filter.
  10. Check for leaks before leaving installation.
CAUTION: All filtration systems contain other parts that have a limited service life. Exhaustion of the service life of those parts often cannot be easily detected. Commonly, it is only after leakage has been observed or water damage has occurred that one is made aware that the service life has been exhausted. To prevent costly repairs or possible water damage we strongly recommend that the bowl or sump of all plastic housings be replaced periodically: every 5 years for clear sumps, and every 10 years for opaque sumps. If your sump has been in use for more than the recommended period, it should be replaced immediately. Be sure to date any new or replacement sump for future reference and indicate the next recommended replacement date.
