Model 400 Installation & Operation Manual
Installation & Operation Information
The
Model 400 feeder will operate on a varying pressure
such as a home well system or on a constant pressure
such as a sprinkler or pool system.
When used as a varying pressure system the non-function-
ing valve (No. 11) must be in place as received. A charcoal
filter must follow the
Model 400 feeder on a varying
pressure system for proper operation. Tests have shown
that one cube of coconut shell activated carbon is the best
carbon to use (grade 9/50, mesh· 8/30).
There are seven positions for varying the amount of
chemical feed. Rotate the top cap (No. 7) so there is a
hole showing through the level desired. There are two hole
selections for each hole in the cap (No. 7).
The smaller hole will dispense the greatest amount and
selecting a lower hole on the cap will increase the output.
Approximate chlorine readings using a 42 gallon pressure
tank out of the
Model 400 feeder ·per pump cycle in PPM,
for each hole are; 1=2, A=3.5, 2=:=8, B=l3, 3=30,
C=40 and with no holes showing, the off position is 60
plus.
These readings are obtained with no iron or hydrogen
sulfide using the chlorine. Variables that will change the
dilution are: pressure tank size, large volumes of water
flow while the pump is building pressure to shut off, horse
power of the pump, and a water logged pressure tank or
air pressure is low or high in the air bag.
The
Model 400
feeder will dispense the same amount of chemical for each
cycle of the pump from maximum to minimum pressure.
When used on a constant-pressure and flow it is neces-
sary to replace the valve (No.11). Replace it with the
optional adjustable valve (No. 20). It may be necessary to
install the optional screen filters (No. 19) in the top inside
hole of (No. 8) and screen (No. 18) in the adjustable inlet
hole when using chemicals other than chlorine, When
using the unit for constant pressure and flow such as a
sprinkler system or pool; install the unit on the output to
the sprinkler heads or on the return line to the pool. The
adjustments for the constant pressure system should have
no holes shown through in the off position. The amount of
chemical dispensed is controlled with the adjustable rate
of feed valve on the outside of the unit. It may be neces-
sary to adjust the unit if flow is increased or decreased.
DANGER: Do Not Mix Different Types or Brands of Chlorine, an Explosion Can Occur.
