INSTALLATION PROCEDURE
Water Supply Connection and Bypass Valve
To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual Bypass Valve has been installed at the
factory. The Bypass allows raw water to be manually routed around the filter.
1. Position filter at desired location for installation. If a water softener is to be installed, the filter should be
positioned first and then the softener. (See Installation Diagrams.)
2. The filter material is shipped separately from the mineral tank. The tank must be loaded with material after tank
has been placed at the desired location.
A. Remove the control valve by unscrewing from the tank.
B. Place a media funnel in hole on top of tank.
C. Block distributor tube to prevent material from entering the tube while filling.
D. Pour several gallons of water in the tank. (Fill tank about 1/3 full.)
E. Pour in the required filter media. The required quantity and type of media is listed in the filter specifications.
F. After filling the tank with material, use a garden hose or several buckets to fill the tank with water. This will
permit the filtering media to become soaked while preparing the installation and will prevent the control valve
from being plugged with floating material on initial backwash.
G. Remove funnel and clean filter media from tank threads.
H. Remove cap from distributor tube.
I. Replace control valve on mineral tank.
3. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
4. Cut main line and install appropriate elbows and extensions.
CAUTION:
Raised arrows located on the sides of control valve body and bypass valve indicate proper direction
of water flow. Install inlet and outlet piping in direction of arrows. It is recommended that a vacuum breaker be
installed on the inlet plumbing.
Drain Line Installation
1. The drain line flow control assembly is pre-assembled for your convenience. Should you choose to hard plumb
the drain line, please remove the barb fitting. The flow control housing can be removed by removing the clip and
pulling straight out on housing.
NOTE:
When re-installing the drain line flow control housing, be sure you hear and feel the O-Ring pop into place
before inserting the clip.
2. Install 1/2" I.D. drain line tubing (not included) from hose barb to an open drain. A 4" gap between end of the drain
line and the open drain is required to prevent waste water back-flow. Keep the drain line as short as possible.
An overhead drain line can be used if necessary, but should discharge below the control valve. A siphon trap
(taped loop) at the outlet of the drain line is advisable to keep the drain line full and to assure correct flow during
backwash. Elbows or other fittings must be kept at a bare minimum.
NOTE:
Where the drain line is elevated above the control valve or exceeds 20 feet in length, 3/4" I.D. drain line
tubing should be used.
