General installation & Guide

The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments but are not designed to support the weight of a system or the plumbing.

Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black o-rings but is not necessary. Avoid any type of lubricants, including silicone on red or clear lip seals.

Do not use pipe dope or other sealants on threads. Teflon tape must be used on the threads of the 1” or the ¼” connection and on the threads for the drain line connection. Teflon tape is not necessary on the nut connections or cap because o-rings seals are used. The nuts and caps are designed to be tightened by hand or with the special plastic service wrench, #V3193-XXX. If necessary a pliers can be used to unscrew the nut or cap. Do not use a pipe wrench. Do not place screwdriver in slots on caps and/or tap with a hammer.

1. The distance between the drain and the water filter should be as short as possible. All plumbing should be done in accordance with local plumbing codes.
2. Do not install any water filter with less than 10 feet of piping between its outlet and the inlet of a water heater.
3. Do not locate unit where it or its connections (including the drain and overflow lines) will ever be subjected to room temperatures under 34F.
4. Inlet/outlet plumbing: connect to a supply line and install an inlet shutoff valve.
5. Drain line: Be sure that the drain can handle the backwash rate of the system and install a flexible plastic tube to the Drain Line Assembly.
6. Serial number: Record the serial number on the installer’s and customer’s records.
