Before You Start
q Read
all steps and guides carefully before installing and using your undersink drinking water filter system. Follow all steps exactly to correctly install. Reading this manual will also help you to get all the benefits from the undersink drinking water filter system.
q Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on disinfected
waters that may contain filterable cysts.
q All plumbing should be done in accordance with local codes and requirements. In Massachusetts,
plumbing code 248 CMR 3.00 and 10.00 shall be adhered to. Consult with your licensed plumber.
q The undersink drinking water filter system works on water pressures of 30 psi (minimum) to 125 psi
(maximum). If your house water pressure is over the maximum, install a pressure reducing valve in the
water supply pipe to the filter system.
q Do not install the undersink drinking water filter system outside, or in extreme hot or cold temperatures. Temperature of the water supply to the undersink drinking water filter system must be between
40°F and 100°F. Do not install on hot water.

Installation Steps
Step 1 - Cold Water Supply Fitting
Check and comply with local plumbing codes as you plan, then install a cold feed (supply) water fitting.
The fitting must provide a leak-tight connection to the water filter 3/8" tubing. A typical connection using
the included water supply fitting is shown in Figure 2A. An optional connection using standard plumbing
fittings (not included) is shown in Figure 2B.
Cold Water Supply Fitting
1. Close the water shut off valve that is immediately before supply fitting and open faucets to drain water
from the sink cold water pipe.
2. Remove nut that connects the cold water faucet to cold water plumbing.
3. Thread water supply fitting onto pipe and reconnect nut to bottom of fitting.
Optional Pipe Fittings (compression type shown)
NOTE: Be sure to turn off the water supply and open a faucet to drain the pipe.
Complying with plumbing codes, install a fitting on the cold water pipe to adapt 3/8" OD tubing. A typical
connection is shown in Figure 2B. If threaded fittings are used, be sure to use pipe joint compound or
thread sealing tape on outside threads.
