Camshaft Cycle Positions
The front end of the camshaft has an indicator cup. The cup has
slots in the outer edge and cycle numbers on the inside face
(Figure 18).
Remove the cover and look over the top of the Analyzer control
to view the cycle numbers. The number at the top indicates the
current cycle position of the control valve. The corresponding slot
for the number is positioned at the optical sensor, which is rotated
approximately 90 degrees out of phase.
Note:
If electrical power is not available, the camshaft can be
rotated counterclockwise by hand if the motor
is removed.

Disinfection of Water Conditioning Systems
The materials of construction in the modern water conditioning
system will not support bacterial growth, nor will these materials
contaminate a water supply. During normal use, a conditioner may
become fouled with organic matter, or in some cases with bacteria
from the water supply. This may result in an off-taste or odor in
the water.
Some conditioners may need to be disinfected after installation
and some conditioners will require periodic disinfection during
their normal life.
Depending upon the conditions of use, the style of conditioner, the
type of ion exchanger, and the disinfectant available, a choice can
be made among the following methods.
Sodium or Calcium Hypochlorite
These materials are satisfactory for use with polystyrene resins,
synthetic gel zeolite, and bentonites.
5.25% Sodium Hypochlorite
These solutions are available under trade names such as Clorox*.
If stronger solutions are used, such as those sold for commercial
laundries, adjust the dosage accordingly.
1. Dosage
• Polystyrene resin; 1.2 fluid ounce (35.5 mL)
per cubic foot.
• Non-resinous exchangers; 0.8 fluid ounce
(23.7 mL) per cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required
amount of hypochlorite solution to the well of the
regenerant tank. The regenerant tank should have
water in it to permit the solution to be carried into the
conditioner.
B. Proceed with the normal regeneration.
Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in
several forms including tablets and granules. These solid materials
may be used directly without dissolving before use.
1. Dosage
A. Two grains (approximately 0.1 ounce (3 mL)
per cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required
amount of hypochlorite to the well of the regenerant
tank. The regenerant tank should have water in it
to permit the chlorine solution to be carried into the
conditioner.
B. Proceed with the normal regeneration.
