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. (Do not fill through dome hole, if installed.)
B. Use cap provided to place over top of distributor tube to prevent material from entering tube while filling.
C. Place media funnel (part # U-1006) in hole on top of tank.
D. Pour several gallons of water in the tank. (Fill tank about 1/3 full.)
E. Pour in the required filter media. No gravel is required. The required quantity of media is listed in the
filter specifications.
Note: If rebedding an existing unit and the system utilizes a standard tube & basket style distributor, a
“D” gravel underbedding will be required.
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 pre
vent 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. Do not use Teflon tape or paste on valve threads, as the valve to
tank o-ring seals this joint.
Caution: Be extremely careful to position distributor tube into control valve distributor tube pilot hole.
3. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
4. Cut main line and install appropriate elbows and extensions. Inlet and outlet connections on the control valve are 3/4"
FNPT. (1" FNPT for WF30 and WF40.)
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.
- Drain Line Connection -
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose barb and
wrap threads with Teflon tape. Reinstall drain line hose barb. Caution: Hand tighten only! Replace drain line
assembly and reinstall 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 backflow. 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 syphon trap (taped loop) at the
outlet of the drain line is advisable to keep the drain line full and 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.
