4. Remove the meter adapter. Be careful not to 

misplace any of the O-rings.

5. Use a needle-nose pliers to grasp one of the four 

vanes of the gland, Figure 18, and pull straight out 
to remove the gland from the adapter.

Figure 18

6. Carefully remove the turbine wheel from the 

housing. Use a toothbrush to lightly scrub the iron 
off the magnet. Iron buildup on the wheel surfaces 
can be removed by soaking the wheel in a mild 
sodium hydrosulfite (e.g., RoVer*) solution for a few 
minutes, then flushing thoroughly with water.

7. Carefully reinstall the turbine wheel into the 

adapter. Make sure that the shaft of the wheel seats 
into the bearing of the adapter and that the dimple 
on the wheel faces you.

8. Carefully reinstall the gland into the adapter. Make 

sure that the shaft of the wheel seats into the 
bearing of the gland. Press the gland all the way in 
and check that the wheel rotates freely.

9. Reinstall the meter adapter, O-rings, piping boss or 

bypass valve. Tighten all fasteners and turn on the 
water supply or put the bypass valve(s) into the 
service position. Purge the air out of the system.

To check for proper meter operation, open a 
downstream faucet and observe the water flow 
indication (flashing colons on time display) on the 
control display.

Disinfection of Water Conditioners

The construction materials of the water conditioning 
system do not support bacterial growth or contaminate 
the water supply. However, we recommend that the 
conditioner be disinfected after installation and before 
the conditioner is 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 exchanger, and disinfectant 
available.

Sodium Hypochlorite 5.25%

Sodium Hypochlorite solutions can be used with 
polystyrene resin, synthetic gel zeolite, greensand, and 
bentonites and are available under trade names such 
as Clorox, Linco, Bo Peep, White Sail, and Eagle Brand 
Bleach. Adjust the dosage if stronger commercial 
solutions are used.

The recommended dosage for 5.25% solutions is:

Polystyrene resin: 1.2 fluid ounces per cubic foot.

Non-resinous exchangers: 0.8 fluid ounce per 
cubic foot.

Complete the following steps to disinfect the 
conditioner:  Add the sodium hypochlorite solution to 
the brine well of the brine tank.  Make sure that the 
brine tank has water in it so the solution is carried into 
the conditioner.  Proceed with normal regeneration.  
Refer to the Manual Regeneration section in this 
manual.

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 recommended dosage for calcium hypochlorite is 
two grains (approximately 0.1 ounce) per cubic foot.

Complete the following steps to disinfect the 
conditioner: Add the calcium hypochlorite solution to 
the brine well of the brine tank. Make sure that the brine 
tank has water in it so the solution is carried into the 
conditioner. Proceed with normal regeneration. Refer to 
the Manual Regeneration section in this manual.
