You can determine whether you have the WaterGroup E50TFC-3 or E75TFC-3 model system by checking the membrane production rate. The E75TFC-3 model has a membrane production rate of 75 US gallons per day (USGPD), while the E50TFC-3 model's production rate is not explicitly listed but would be lower. Additionally, you can verify the model number on the system itself or in the user manual.

Now you can relax and enjoy the benefits of great tasting water supplied by your reverse osmosis drinking water system. Remember that good quality water is important to maintaining a healthy lifestyle. You can also feel good about the money you have saved by installing your own drinking water system instead of dealing with the expense and hassle of bottled water delivery.
Rejection percentages are dependent on the supply conditions and the substance being measured. Notes: The performance of a reverse osmosis membrane is highly dependent upon pressure, temperature and TDS. The actual volume of product water and rejection percentage will vary with differences from the test conditions that membrane ratings are based upon.
Out of the box, your new R.O. System should be supplied with the following items. If any items appear to be missing, please contact the distributor who sold the system. 1. Pressure Tank 2. Reverse Osmosis System, complete with tubing bundle 3. Reverse Osmosis membrane element (in sealed protective bag) 4.
Installation All State/Provincial and local government codes regarding installation of these devices must be observed. Verify Water Supply is Potable The water supply must meet provincial/state and/or national standards for potable drinking water. Water samples should be sent to a certified laboratory for analysis. Placement of Components Placement of the various components of the system will vary from installation to installation.

Installation of Spigot See separate installation instructions for spigot Installation of Membrane Important: Keep the membrane and your hands clean in order to avoid bacterial contamination of the membrane. 1. Disconnect the hose on the end of the membrane housing end cap. 2.
Start-Up Procedure WARNING: To prevent microbiological growth and freezing, this reverse osmosis system contains a preservative solution which, if ingested, may cause irritation of the gastrointestinal tract, colic, diarrhea or other similar symptoms. Therefore, 5 gallons (approximately two full tanks) must be drawn from the spigot to flush out the preservative.
- The pre-filter contains a 5 micron mechanical filter element. Its function is to remove suspended particles from the feed water, thus reducing the possibility of clogging the reverse osmosis membrane. The pre-filter element should be replaced every twelve months or earlier depending on the quality of the feed water.
• Whenever evidence of harmful bacteriological contamination of the system has been discovered. In this case contact your local water treatment specialist to disinfect your reverse osmosis system, and identify and eliminate the source of contamination. IMPORTANT: This Reverse Osmosis Drinking Water System should not be used on any water supply sources that are microbiologically unsafe or of unknown quality without adequate disinfection before and/or after the system.

Sanitization Steps STEP 1: TURN OFF WATER SUPPLY - CLOSE INLET SUPPLY NEEDLE VALVE ALL THE WAY STEP 2: DEPRESSURIZE SYSTEM - OPEN FAUCET SUPPLY UNTIL ALL WATER IS EMPTIED Use a clean drip pan or basin to continue to catch any spilled water remaining in the housings as you remove the membrane and cartridges.
Page 17
STEP 8: POUR THE MIXED DISINFECTANT SOLUTION INTO THE 1ST PRE-FILTER SUMP AND RE-INSTALL. STEP 9: OPEN THE INLET SADDLE VALVE AND OPEN THE FAUCET. WHEN WATER BEGINS RUNNING FROM THE FAUCET AGAIN, CLOSE THE FAUCET AND ALLOW THE PRESSURE TANK TO FILL FOR 5 - 10 MINUTES. WHEN THE PRESSURE TANK FEELS LIKE IT HAS FILLED, CLOSE THE INLET SUPPLY NEEDLE VALVE.
