FEATURES:

Operating Profile

Water is ltered to NSF 42 & 53 standards for particulate,
chlroine, chloramine, taste and odor using replaceable cartridge
ltration. Softener will remove hardness to less than 1/2 gpg
when operated in accordance with the operating instructions.
The system includes two tanks. This duplex conguration oper­ates with one tank on-line during service. During regeneration
cycles, one tank provides water to service and to the regener­ating tank. A water meter initiates system regeneration. The
water meter measures the processed volume and is adjustable.
Service ow is down-ow and regeneration ow is up-ow.

CB15K Hollow Carbon Filter

The CB15K Hollow Carbon Filter located inside of the WS-55
cabinet is NSF 42 & 53 certied up to 15,000 gallons for the
reduction of Chloramine. The lter is replaced based on psi or
15,000 gallon capacity. Maximum working pressure of the lter
is 125 psi.

Regeneration Control Valve

The regeneration control valve is top mounted (top of media
tank), and manufactured from non-corrosive materials. Control
valve does not weigh more than four pounds. Control valve
provides service and regeneration control for two media tanks.
Inlet and outlet ports accept a quick connect, double o-ring
sealed adapter. Interconnection between tanks is made through
the regeneration valve with a quick connect adapter. Control
valve operates using a minimum inlet pressure of 15 psi. Pres­sure is used to drive all valve functions. No electric hook-up is
required. Control valve will incorporate four operational cycles
including; service, brine draw, slow rinse, and a combined fast
rinse and brine rell. Service cycle operates in a down-ow di­rection. The brine cycle ows up-ow, opposite the service ow,
providing a countercurrent regeneration. Control valve contains
a xed orice eductor nozzle and self-adjusting backwash ow
control. The control valve will prevent the bypass of hard water
to service during the regeneration cycle.

Conditioning Media

Each softener includes uniform bead cation resin having a mini­mum exchange capacity of 30,000 grains/ft when regenerated
with 15.0 lbs/ft. The media is solid, of a proper particle size
and contains no plates, shells, agglomerates or other shapes,
which might interfere with the normal function of the water
softener.

Brine System

A combination salt storage and brine production tank is manu­factured of corrosion resistant, plastic. The brine tank has a
chamber to house the brine valve assembly. The brine oat
assembly allows for adjustable salt settings and provides for a
shut-off to the brine rell. The brine tank includes a safety over­ow connection to be plumbed to a suitable drain.

Salt Alarm

Salt alarm consists of an alarm box and a brine sensor. Brine
sensor is mounted internally on the grid plate and operates on
the specic gravity of proper brine concentration. An alarm
condition is triggered when the concentration falls below ac­ceptable level for more than 15 minutes. The alarm is both an
80-db audible alarm every 3 seconds and a red LED ash every
7 seconds. The alarm box operates on three AA batteries and
connects to the brine sensor with a standard 2-wire phone cord
(7' phone cord supplied).

Media Tanks

The tanks are designed for a maximum working pressure of 125
psi and hydrostatically tested at 300 psi. Tanks are made of en­gineered plastic with a 2.5 in. threaded top opening. Each tank
is NSF approved. Upper distribution system is of a slot design.
Lower distribution system is of a at plate design. Distributors
will provide even ow of regeneration water and the collection of
processed water.
