Manual Valve Operation
The camshaft may rotate manually to actuate the
valve functions for service purposes.
1. Unplug the wall-mounted transformer.
2. Remove the rear cover by pulling back on the tab
provided on the cover. Next, lift the rear cover off
the valve, Figure 2.
3. Rotate the camshaft COUNTERCLOCKWISE
until the appropriate valve is opened by the
camshaft lobe. Use the regeneration cycle
indicator as a guide to which valve discs are
open.
4. When the service is complete, rotate the
camshaft so the regeneration cycle indicator is
pointing to the end of the refill cycle.
5. Reinstall cover, reconnect electric power, and
reset the time of day.
6. The display will shoe Err3 and the motor will start
up. After approximately 5 minutes, the indicator
will point to REGENERATION COMPLETE and
the control starts alternating the display between
TIME OF DAY and CAPACITY.
7. The conditioner is now in operation.
Additional Features
When your dealer installs the conditioner, the control
settings are adjusted to meet your soft water needs.
However, there are additional features which your
dealer can incorporate into the control. These
features are: 12 or 24-Hour Clock, Metric Units of
Measure, Calendar Override and Immediate
Regeneration.
12 or 24-Hour Clock
The standard clock is a 12-hour with a PM indicator.
An optional 24-hour clock without a PM indicator is
available. Time can be set from 00:00 to 23:59. This
option applies to both the Time of Day and Time of
Regeneration settings.
Metric Units of measure
The standard units of measure are U.S. values. Hard-
ness is in grains per gallon, Salt in pounds, and
Capacity is in kilograins. The metric option changes
these to milligrams per litre, kilograms, and Kilograms
respectively. All controls settings use the metric
values when the metric option is selected.
Calendar Override
The Calendar Override option is a method of forcing
the control to regenerate after a preset number of
days, is normal demand-based regeneration does not
occur first. This feature is not set at the factory; your
dealer can set it at 1 to 30days.
Immediate Regeneration
The control is factory set to wait until the Time of Day
reaches the Time of Regeneration to begin a regen-
eration. Your dealer can program the controller to
regenerate any time the capacity remaining reaches
zero. Remember that you do not have soft water
available during any regeneration.
Disinfection of Water Conditioners
The construction materials of the water conditioner
system do not support bacterial growth or
contaminated the water supply. However, we
recommend that the conditioners be disinfected after
installation and before the conditioners are used to
treat potable water. In addition, a conditioner can
become fouled with organic matter during normal
usage or with bacteria from the water supply. Periodic
disinfection is recommended for all conditioners.
Use one of the following methods of disinfection
based on operating conditions, style of conditioner,
type of ion exchange, and disinfectant available.
Sodium Hypochlorite
Sodium Hypochlorite, 5.25% solutions, can be used
with polystyrene resin, synthetic gel zeolite,
greensand, and bentonites and are available under
trade names such as Chlorox, Linco, Bo Peep, White
Sail and Eagle Brand Bleach. Adjust the dosage if
stronger commercial solutions are used.
The recommended dosage for 5.25% solution is:
•
Polystyrene resin: 1.2 fluid ounces per cubic foot.
•
Non-resinous exchangers: 0.8 fluid ounces per
cubic foot.
Calcium Hypochlorite
Calcium Hypochlorite, 70% available chlorine, is
available in several forms including tablets and
granules. These solid materials can be used directly
without dissolving before application. The recom-
mended dosage for Calcium Hypochlorite is two
grains (approx. 0.1 ounce) per cubic foot.
Complete the following steps to disinfect the
conditioner:
1. Add the Calcium Hypochlorite to the brine well of
the brine tank. Make sure that he brine tank has
