Model 400 Feeder - Trouble Shooting

SYMPTOMS

Definition of Pump Cycle

Lid is hard or impossible to remove

(No. 4)

Low pressure or low water flow

after carbon tank.

Tube (No. 8) appears warped or

melted.

Chlorine smell after carbon,

and/or

Unit appears to be using chemical

too fast.

High odor.

and/or

Unit appears not to be dispensing

the proper amount of chemical.

Low or occasional odor.

and/or

Unit appears not to be dispensing

the proper amount of chemical

Odor only in the hot water.

1 - (From the time the pump shuts off until the time the pump turns on). The amount of water

dispensed is depended on the size and differential pressure of the pressure tank. The

Model 400 feeder dispenses the same amount of chemical for each pump cycle regard-

less of pressure tank size or differential pressure settings.

1 - Line pressure has not been relieved.

2 - Unit was not previously cleaned when re-filled and inside tube is plugged (No. 8). The unit

is under pressure. Be extremely careful when removing a lid under; pressure. It can blow

off with extreme force.

1 - Carbon fouled and needs back washing or replaced

1 - Do not mix different types or brands of chlorine. Make sure no oil or petroleum products

mix with the· chlorine.

1 - No carbon or carbon tank is internally bypassing or carbon is fouled with oxidized iron

2 - Pressure tank is water logged or pressure is low or high in the air bag

3 - Improper Model 400 feeder adjustment or adjustment holes are plugged and need clean-

ing. Tube (No. 8).

4 - Improper pressure switch adjustments. There should be a minimum differential pressure

of 20 PSI.

5 - The chart for chlorine output is for a 42 gallon pressure tank. If using a smaller tank such

as a 20 gallon tank, cut the chlorine output by one half. The Model 400 feeder will output

the same amount of chemical for each pump cycle and a smaller tank is delivering less

water on each pump cycle increasing the chemical concentration.

1 - Unit needs chlorine or it is over filled. (Max. 3/4 full)

2 - Wrong Chlorine. Only calcium hypochlorite tablets will dispense high amounts of chlorine.

Stabilized chlorine is not approved by the FDA for potable water.

3 - Pump continues to run and not cycling on and off due to large volume of water flow or

pump is too small for demand. No chemical will dispense when the pump is running.

4 - Pressure was released from the unit and fluid was not removed from the unit before re-

pressurizing the unit.

5 - Carbon tank internally bypassing.

1 - All of the above for high odor.

2 - Extra high odor. Unit needs to be adjusted for a greater chlorine output.

3 - The chart for chlorine output is for a 42 gal. pressure tank. If using an 82 gal. tank, double

the chlorine output from the Model 400 feeder. The Model 400 feeder will output the

same amount of chemical for each pump cycle and a larger tank is delivering more water

on each pump cycle-and decreasing the concentration.

4 - Wrong amount of carbon, one cube minimum.

1 - Magnesium anode rod in the hot water tank. Remove the rod.
