Installation Instructions
All government codes and regulations governing the installation of these devices must be observed.
CAUTION: 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 Noryl bypass valve and/or poly pipe, 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 and/or the amount of copper pipe being
replaced with poly. See Figure 1.
In all cases where metal pipe was originally used and is later
interrupted by poly pipe or the Noryl bypass valve as in
Figure 1 or by physical separation as in Figure 2, an
approved ground clamp with no less than #6 copper
conductor must be used for continuity, to maintain proper
metallic pipe bonding.
Check your local electrical code for the correct clamp and
cable size.
1. Determine the best location for your water softener,
bearing in mind the location of your water supply lines,
drain line and 120 volt AC electrical outlet. Subjecting
the softener to freezing or temperatures above (110°F)
will void the warranty.
Media Installation (When Necessary)
• Remove the valve from the mineral tank.
• Temporarily plug the open end of the riser tube to ensure that no resin or gravel falls down into the distribution.
• Fill mineral tank one quarter full of water to protect distribution during gravel installation.
• Slowly and carefully add the gravel support bed and the softener or filtration media leveling each layer as it is placed
into the tank.
• Unplug the riser tube, carefully position the valve over it and turn the valve into the threads in the fiberglass tank,
tightening securely into tank. Note: Ensure that the internal O-ring in the valve fits securely over the riser tube.
Silicone grease (#13691) or other food grade lubricant may be applied to the O-ring to ease installation of the riser
tube. DO NOT use petroleum based lubricants as they will cause swelling of O-ring seals.
• The softener or filter is now charged with softening resin.
• It is recommended that the softener or filter tank now be completely filled with water (SLOWLY) to soak the resin or
filtration media before startup. This will allow the media to absorb water as well as help displace any trapped air.
This will reduce the chance of backwashing resin or filter media out of the tank during the initial backwash on
startup.
