Water Pressure: A minimum of 25 pounds of water pressure
(psi) is required for regeneration. Maximum 125 psi.
Water Quality: On rural water supplies there is often a problem
with sand or sediment in the water. (This problem occasionally
occurs in public water supplies.) If the water is not filtered before
being softened, the sand and sediment will plug up the water
softener restricting the flow through the resin bed. This problem
often requires rebedding of the mineral tank. Note: Well and/
or pump problems affecting the operation of the softener are
repairs that are not covered under warranty. To prevent these
unnecessary, and expensive repairs not covered under warranty,
we recommend the installation of an in-line filter system ahead
of the softener.
Electrical: A continuous 110 volt, 60 cycle current supply is
required. Make certain the current supply is uninterrupted and
cannot be turned off with another switch. All electrical connec-
tions must be connected per local codes.
Surge protection is
recommended with all electric controls.
Existing Plumbing: Condition of existing plumbing must be
free from lime and iron build-up. Piping that is built-up heavily
with lime and/or iron must be replaced. If piping is blocked with
iron, additional equipment must be installed ahead of the water
conditioner to correct the problem.
Drain Line: The conditioner should be located close to a drain.
Avoid overhead drain lines if possible to prevent back pressure
on the brine injector. Overhead drains are not to exceed 8 feet
above the floor and no more than 20 feet in length. The pipe
size for the drain line should be a minimum of 3/4”. Backwash
flow rates in excess of 7 gpm or length in excess of 20’ require
1” drain line.
Bypass Valves: Always provide for the installation of a bypass
valve.
Softening: It is recommended that the conditioner be installed
to soften both the hot and cold water supply. A separate hard
water faucet may be plumbed for drinking purposes if you desire.
Outside faucets should be left on hard water.
Caution: Water temperature is not to exceed 110°F; the condi-
tioner cannot be subject to freezing conditions, or to a vacuum
due to loss of pressure (such as a water main break).
