ADDITIONAL INFORMATION: Operating Temperature Range = 34° to 110°F (1° to 43°C). Operating Pressure Range = 20 to 120 psi (1.37 to 8.27 bar). The manufacturer reserves the right to make product
improvements which may deviate from the specifications and descriptions shown above, without obligation to change previously manufactured products or to note the change.
CAUTION: These products are not intended to be used to treat water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
NOTES:
(1) 10lb/cu.ft. salt dosage is the standard factory setting. (2) The Service Flow Rate given will not exceed a pressure drop of 15psi. (3) Dimensions of cylindrical tanks shown are diameter (or width) x height.
Cabinets shown as length x width x height.
How Your Water Conditioner Works
Hard water enters your home through the main supply line, enters your water conditioner, and passes down through a bed
of ion exchange resin which softens the water. An ion exchange process takes place in which the resin beads capture and
hold calcium and magnesium, the hardness impurities, while the water takes on sodium ions. The soft water then flows up
and into your household water line.
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.
