Posted by Pure Aqua, Inc. on Sep 17th 2015

Place the softener tank where you want to install the unit making sure the unit is level and on a firm base.
During cold weather, the installer should warm the valve to room temperature before operating.
All plumbing should be done in accordance with local plumbing codes. The pipe size for residential drain line should be a minimum of 1/2 inch (13 mm). Backwash flow rates in excess of 7 gpm (26.5 Lpm) or length in excess of 20 feet (6 m) require 3/4 inch (19 mm) drain line. Commercial drain lines should be the same size as the drain line flow control.
Refer to the dimensional drawing for cutting height of the distributor tube. If there is no dimensional drawing, cut the distributor tube flush with the top of the tank.
Lubricate the distributor o-ring seal and tank o-ring seal. Place the main control valve on tank. NOTE: Only use silicone lubricant.
IMPORTANT: For valves equipped with electromechanical timers and stainless steel meters, refer to the Meter Dome and Union Orientation section.
Solder joints near the drain must be done prior to connecting the Drain Line Flow Control fitting (DLFC). Leave at least 6 inch (15 cm) between the DLFC and solder joints when soldering pipes that are connected on the DLFC. Failure to do this could cause interior damage to the DLFC.
Plumber tape is the only sealant to be used on the drain fitting. The drain from twin tank units may be run through a common line.
Make sure that the floor is clean beneath the salt storage tank and that it is level.
