•  Replace the control valve making sure that the distributor tube is inserted into the center hole of the bottom of the 

control valve. 

•  Complete plumbing. 

•  Place the bypass valve in “BYPASS OPERATION”. (Figure 1) 

•  Plug the transformer into a 120V uninterrupted receptacle. 

•  Carbon should be soaked in water for at least one hour before backwashing at full-flow.  The mineral is dry 

and filling too quickly will result in the mineral plugging the drain line and valve assembly.

DRAIN LINE:

 The 3/4” drain line elbow accommodates 5/8” poly tube or 3/4” NPT drain line connections. The nut and 

poly tube insert for the 3/4” drain line elbow is designed for use with flexible, semi-rigid poly tube only. The drain line elbow 

can be rotated so the outlet can be oriented toward the nearest drain.

TO INSTALL 5/8” POLY TUBE DRAIN LINE:

 The poly tube insert is shipped attached to the drain line elbow’s locking 

clip. Press the insert into the drain line (5/8” poly tube not included). Loosen nut of the drain line elbow. Press 5/8” poly 

tube with insert into the drain line elbow until it seats on the back of the fitting. Tighten nut.
The drain line must be piped to an open drain with air gap between the drain and the sewer lines (Fig. C). Under no 

circumstances should there be a direct connection with sanitary sewage facilities. If it is necessary to run the drain pipe 

overhead, (not to exceed 5’ above valve) be sure to increase the pipe size and follow all plumbing procedures to hold 

friction and restrictions to a minimum.
