INSTALLATION

Place filter in desired location close to water supply inlet, after 

pressure tank, and near a source for waste water, (utility sink, floor 

drain or sewer line). A 115/120V, 60Hz uninterrupted outlet is required. 

Keep filter far enough away from walls and other obstructions to allow 

enough room for servicing the unit. If a water softener is also to be 

installed, generally it will be placed in line after the neutralizer or filter. 

From water supply→ neutralizer → filter → softener → to service

ADD MINERALS:

Remove control valve from mineral tank by turning counter-clockwise. Plug open end (top) of distributor tube assembly to 

prevent  mineral from entering 

(Fig. A)

. Add Mineral. 

DO NOT OVERFILL

. There must be at least 16” of space between 

the top of the tank and mineral 

(Fig. B)

. Remove plug from the top of the distributor tube.

Install control valve making sure the distributor tube is slipped into the center hole on the bottom of the control valve. Pipe 

filter into service line. Use of a bypass valve is recommended. Arrows are molded into valve and bypass valve to show 

direction of flow.

OPTIONAL BYPASS VALVE:

 The bypass valve easily connects to the control valve body using nuts that only require 

hand tightening. Install with red knobs in the upward position. Press end of bypass valve with o-rings into valve. Hand 

tighten nuts. Place into  

BYPASS OPERATION (Fig. 4)

.

Avoid getting primer and solvent cement on any part of the o-rings or split rings, bypass valve or control valve.

 DO NOT

 

use pipe dope or any other sealant on threads. Teflon tape is not necessary on the caps because of o-ring seals. 

DO 

NOT

 use Vaseline or other unacceptable lubricants on o-rings. A silicone lubricant may be used on black o-rings.

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. 3). 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.
