Installation 9
Install Backwash Flow Control Washer
Refer to figure 4
1. Locate the thin black flow control washer and the plastic flow control
spacer from the small parts pack.
2. Remove the drain elbow retaining clip and drain elbow from the filter
control valve.
3. Remove the rubber backwash flow control washer and discard it.
4. Install the thin black flow control washer into the filter control valve with
the molded numbers facing the control valve. Install the plastic flow
control spacer. Install the drain elbow and retaining clip.
Plumbing Connections
General Instructions
• Follow local plumbing and electrical codes. Failure to do so may result
in your having to re-do the installation at your expense.
• Take the time to make a clean, professional looking installation. Use
flux and solder sparingly when making sweat connections, and avoid
excessive use of pipe compound. When using galvanized pipe, clean out excess cutting oil and metal chips before assembly.
Foreign objects, if allowed to enter the control valve, can cause operating problems.
• Once the plumbing connections have been made to the Cul-Flo-Valv
®
Bypass, make certain the interior of the valve is clean
and free of debris, lubricate the valve stem o-rings with silicone lubricant, reinsert the stem, and replace the red or blue knob.
Set the Cul-Flo-Valv Bypass in the bypass position by pushing the red knob completely inward. The main water supply line may
then be reopened so that hard water will be available to the household throughout the remainder of the installation process.
Bypass Valve Installation
The bypass valve connects directly to the control valve with a pair
of couplings and two assembly pins (Figure 5). Lubricate all o-rings
on the couplings with silicone lubricant.
On Soft-Minder
®
meter controls, the meter replaces the coupling on
the outlet side of the control. The meter body fits in the same space
as the coupling between the control valve and the bypass. Make
sure that the arrow on the flow meter is pointing in the direction of
flow (Figure 5).
Note: If the ground from the electrical panel or breaker box to
the water meter or underground copper pipe is tied to the copper
water lines and these lines are cut during installation of the bypass
valve, an approved grounding strap must be used between the
two lines that have been cut in order to maintain continuity. The
length of the grounding strap will depend upon the number of units being installed. In all cases where metal pipe was originally
used and is later interrupted by the bypass valve to maintain proper metallic pipe bonding, an approved ground clamp c/w not
less than #6 copper conductor must be used for continuity. Check your local electrical code for the correct clamp and cable size.

Caution! Close the inlet supply line and relieve system pressure before cutting into the plumbing! Flooding could
result!
