Water Meter Maintenance
NotE:
A water meter is used only with the 460i control. If
you are using the 440i or 460tC control, this section
does not pertain to your conditioner.
The metering device used with the 460i demand control may
require simple maintenance. In rare instances, the turbine
wheel of the water meter can collect small particles of
oxidized iron, eventually preventing the wheel from turning.
1. Shut off the water supply or put the bypass valve(s) into the
bypass position.
2. Relieve pressure by opening the Backwash Drain Valve (the
seventh back from the control) with a screwdriver
(Figure 15).
3. Loosen and remove the pipe/tube adapters or 1265 bypass
from the inlet and outlet of the valve body.
4. Using a needle-nose pliers, remove the turbine from the
outlet housing. Grasp one of the four vanes of the outer
gland and pull straight out to remove turbine assembly
from the outlet of the valve (Figure 18).
5. Carefully remove the turbine wheel from the housing.
Use a toothbrush to lightly scrub the iron off the magnet.
Iron buildup on the surfaces can be removed by soaking
the wheel in a mild sodium hydrosulfite solution for a few
minutes. Flush thoroughly with water.
6. Carefully reinstall the turbine wheel into the turbine cage
housing. Make sure that the shaft of the wheel seats into
the bearing of the cage. Reassemble the turbine cage and
check that the wheel rotates freely.
7. Reinstall the turbine cage into the outlet of the valve.
8. Reinstall the pipe/tube adapters or 1265 bypass to the inlet
and outlet of the valve.
9. Turn on the water supply or put the bypass valve(s) into the
service position and purge the air out of the system.
To check for proper meter operation, open a downstream
faucet and observe the water flow indication on the
control display.
Disinfection of Water Conditioners
The materials of construction of the modern water conditioner
will not support bacterial growth, nor will these materials
contaminate a water supply. However, the normal conditions
existing during shipping, storage and installation indicate
the advisability of disinfecting a conditioner after installation,
before the conditioner is used to treat potable water. In
addition, during normal use, a conditioner may become fouled
with organic matter or in some cases with bacteria from the
water supply.
Thus every conditioner should be disinfected after installation,
some will require periodic disinfection during their normal life,
and in a few cases disinfection with every regeneration would
be recommended.
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
Application
These materials are satisfactory for use with polystyrene
resins, synthetic gel zeolite, greensand and bentonites.
5.25% Sodium Hypochlorite
These solutions are commonly known as household bleach. If
stronger solutions are used, such as those sold for commercial
laundries, adjust the dosage accordingly.
1. Dosage
A. Polystyrene resin: 1.2 fluid ounces per cubic foot.
B. Non-resinous exchangers: 0.8 fluid ounce per cubic
foot.
2. Brine tank conditioners
A. Backwash the conditioner and add the required amount
of hypochlorite solution to the brine well of the brine
tank. (The brine 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) per cubic foot.
2. Brine tank conditioners
A. Backwash the conditioner and add the required amount
of hypochlorite to the brine well of the brine tank. (The
brine tank should have water in it to permit the chlorine
solution to be carried into the conditioner.)
B. Proceed with the normal regeneration.
