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.
