Model 77 Countertop Water Filter Basics
1. To install, unscrew the aerator from your sink faucet and attach the filter’s diverter valve in its place. If it doesn’t fit, use one of the enclosed adapters. The diverter valve will fit 90% of the faucets without an adapter, and the enclosed adapters will attach it to almost all others. For the 3% with an unusual thread pattern, consult a good hardware store, or call Pure Water Products at 940 382 3814.
2. To operate the filter, turn on the COLD water to a moderate flow rate, pull out the diverter valve stem, and water will eventually begin to flow through the filter. For initial operation, let the water run for four or five minutes before drinking. When the faucet is turned off, the valve stem will pop back into place and allow normal use of the sink faucet. Note: it may take as much as a day for all trapped air to work out of the new filter cartridge. If water dribbles from the end of the spout after the inlet water is turned off, or
if water appears cloudy, the problem is trapped air. It will correct itself, and in the meantime, the water is safe to drink. Model 77 Countertop MaintenanceThe Model 77 is designed to be trouble-free. However, diverter valves, no matter how good they are, sometimes become clogged with minerals from the water and begin to stick. The best regular maintenance you can do is to remove the diverter valve from the faucet about once a month and drop one or two drops of vegetable oil into the small hole where water enters the valve. Work the stem back and forth until it moves freely. This will add years to the life of the valve and insure smooth, trouble-free operation. Leaks at fittings are rare and can usually be corrected by tightening the fitting or wrapping the treads with teflon tape. If the unit leaks at the bottom where the tower screws to the base, be sure the O-ring in the tower is in place and screw the pieces together firmly. At annual cartridge change, lubricate the O-ring lightly. Silicone grease is the preferred lubricant. If there are problems, large or small, please contact Pure Water Products at pwp@pwgazette.com or 940 382 3814 for immediate attention. |
