The Major Components - How They Work
General Principles of Operation
The three main components of the CCH Feeder are
(from top to bottom) the Tablet Hopper, the Dissolving
Cup section and the discharge tank.The water from the
pool enters the CCH Feeder via the emergency shutoff
valve.The water then enters the Dissolving Cup where it
is distributed to the nozzles for generating the wave to
dissolve the Tablets and the solids removal system.The
chlorinated solution is directed by a single outlet spout
to a channel that directs the solids and chlorinated
solution into the discharge tank where it is discharged
into the pool recirculation system.The amount of
chlorine discharged is determined by three factors:
1.The Grid Type (Normal or High)
2.The # of Cartridges filled with Tablets.
3.The Inlet water flow rate
An ORP controller can be used to regulate Feeder
output by installing a solenoid on the inlet flow line.
Inlet water pressure of 10 to 30 psi will provide
sufficient flow into the CCH Feeder.These pressures will
result in an inlet flow of 0.1-2.0 gallons/minute.
Flow out of the CCH Feeder requires vacuum to
properly evacuate the discharge tank. A minimum
outlet flowrate of 2.1 gpm ensures that the outlet flow
of the CCH Feeder exceeds the inlet flow. Once the CCH
Feeder has been installed, the outlet flow is measured
by watching the level in the Discharge tank. If the
water level is rising as the feeder is running, there is
insufficient outlet flow.

Pre-Startup Checklist
Following the procedure outlined below will ensure a smooth startup of the CCH Feeder. For seasonal operation,
perform this procedure each spring.
IMPORTANT!!
Do NOT put tablets in the Feeder during the start-up operation.
INLET WATER FLOW
The inlet water flow system is designed to provide a
steady sidestream of clean filtered pool water to the
Feeder.
1. Switch on the pool recirculation system and open
all valves to the Feeder. Leave lid closed.
2. Adjust Inlet flow on flow indicator to 0.3 gpm.
Wait 10 seconds or until nozzles are under water .
3. Remove the cartridges. Increase flow to 1.3 gpm
and check to see that all four wave nozzles are
making a wave that rises into the dissolving cup.
4. Check all lines leading to the Feeder for leaks.
Hand tighten all fittings if any leaks are found.
OUTLET WATER FLOW
The float on the Discharge Valve rises with the water
level and allows the pool pump/venturi suction to draw
the chlorinated water into the pool’s recirculation
system as the Discharge Tank fills with water. When the
water level drops, the float falls, shutting off the valve.
The Discharge Valve also contains a check valve to
prevent pool water from backing up into the Discharge
Tank. Use the following procedure to ensure that the
outlet water flow system is operating properly.
1. With the tablet hopper and dissolving cup of
the Feeder temporarily out of the way, fill the
Discharge Tank with sufficient water to open the
Discharge Valve – use a hose or pail.
2. The float should rise, opening the Discharge Valve,
allowing water to be drawn out by the pool pump
suction or venturi system.
3. Check the system for leaks. If small air bubbles are
visibly moving, there may be an air leak.Tighten
the connectors and make sure that the tubing
was properly installed in the fittings. (NOTE: Air
bubbles near the CCH Feeder body that do not
move are normal and do not indicate leaks.)
4. Check for air leaks after the Discharge Valve
closes.

After completing the PRE-START-UP CHECKLIST,
and establishing that all components of the Feeder are
operating properly, your CCH Feeder is ready for start-up.
Routine Maintenance of the CCH Feeder
Feeder maintenance is minimized when proper pool
water balance is maintained. Maintain pool water
chemistry as follows:
Total Alkalinity 60-80ppm
Calcium Hardness 200-1800ppm
PH 7.2-7.6
Adherence to these recommendations at all times will
ensure the most effective and economical performance
from the CCH Feeder.
NOTE: The use of CO2 to lower pH will raise Total
Alkalinity. High total alkalinity (over 80 ppm) will
increase scale and solids buildup in Feeder.
WARNING
Use ONLY EPA Registration Number 1258-1233
Tablets in the Feeder. The use of any other treatment
chemicals will void the warranty. DANGER: Under no
circumstances mix calcium hypochlorite with other
forms of concentrated chlorine or other chemicals.
Fire and/or explosion may result. Caution must be
used when refilling dispenser.
KEEP OUT OF REACH
OF CHILDREN
Output Rate Vs Inlet Flow Rates and # of
Cartridges filled with Tablets
1. Refer to Charts on pages 7 and 8 to determine the
# cartridges recommended to be filled with CCH
Feeder Tablets and grid type according to pool size
and type.
Note: Always use the minimum number of
cartridges possible to maintain the desired chlorine
residual.This will promote greater flow through
the Feeder to improve solids removal and lessen
maintenance.
2. Open all valves to the pool and the outlet ball valve
of the Feeder.
3. Refer to the charts on page 7 and 8 to determine
an approximate start-up Inlet Flow setting for
your pool (or be certain that the ORP Controller is
calibrated and the set-points are correct). Set the
Flow Indicator (top of float) at the recommended
setting using the inlet ball valve. Note: For best
Feeder performance with an ORP controller, set
the flow indicator for a pool 30% larger than the
one at your facility.This will assist in maintaining
desired Free Available chlorine level in pool without
overshooting ORP set point.
4. Monitor the water flow to the Feeder daily to
ensure that a proper flow is being maintained.
5. During the first few days of operation, check
chlorine level in the pool frequently to establish the
best Inlet Flow setting (or ORP Controller setting)
for your pool. Adjust the chlorine output either up
or down to maintain desired chlorine residual or
adjust the ORP set point.
Startup Procedures

Arch Chemicals, Inc. • 1200 Lower River Road • P.O. Box 800 • Charleston, TN 37310-0800 7
rev.6 (3/23/16)
Start-up settings are based on historical data for
average chlorine consumption in Public Pools
according to pool or spa type. Outdoor Pools and
Spas consume considerably more chlorine than Pool
and Spas that are indoors. Weather, Stabilizer level
and Bather load all have a major impact on chlorine
consumption.
Important: Always attempt to increase feed rate by
first increasing the inlet flow rate to attain the desired
free chlorine residual. If the desired free chlorine
residual can’t be attained by increasing the inlet flow
rate, add tablets to an additional cartridge.
Note: Remove unused cartridges from the Hopper
prior to start-up and store for future use.
Below are the feed rates for the CCH Feeder with the
different grids, flow rates and # of cartridges filled
with tablets. If the current feed rate is know from using
either liquid chlorine (Bleach) or trichlor, set the CCH
Feeder feeder to produce that feed rate. If the feed
rate is unknown, use either the chart or the graph to
determine the appropriate Start-up setting for the pool/
spa type and size.
Note: 1 lb of Trichlor has the equivalent of 0.9 lbs of
Av. Cl. 1 gallon of 10-12% bleach has the equivalent
of 1 lb of Av. Cl.
The CCH Feeder is NSF listed for an output rate of 18#’s of Av. Cl./day. State and local health codes will
determine the maximum pool/spa size that can be treated with a single CCH Feeder. Some states may allow the
use of multiple feeders to treat larger pools.
Calculations:
The first calculation is for a state code that requires a specific weight of Av. Cl./10,000 gallons per day.
Example 1: The state health code requires 3 lbs Av. Cl. /10,000 gallons per day.
With an output rate of 18 lbs. Av. Cl./day the CCH Feeder will treat a pool up to 60,000 gallons per the health code.
The calculation is as follows:
18/3 x 10,000 = 60,000 gallons

The second calculation is for a state code that requires a specific chlorine dosage per turnover (6 hrs).
Example 2: The state health code requires 10ppm (mg/l) Av. Cl. per 6 hr turnover.
24/6 = 4 turnovers per day.Therefore 10ppm x 4 = 40ppm per day chlorine dosage required.
18 lbs Av. Cl/0.000040 = 450,000 lbs water per day at 40ppm or 450,000/8.34 = 53,956 gallons.

Inspection:The solids build-up and cleaning frequency
required for the unit will depend on the amount of
tablets used and the pool water chemistry. Described
below is the easiest way to remove solids and minor
scale buildup using dilute Muriatic Acid.
WARNING
Perform cleaning operation in a well ventilated area.
Chlorine gas may evolve causing serious injury or
possible death. Use proper protective equipment per
MSDS when handling chemicals. Use caution handling
feeder parts and solution as they contain chlorine that
can bleach clothing or cause injury.
Maintenance Procedure Steps
1. Note the inlet flow setting. Close the inlet and
outlet shutoff valves to the Feeder.
2. Remove tablet cartridges from the hopper and
empty tablets into a clean dry bucket. Be sure to
remove all pieces of tablets. If necessary, rinse
any heavy solids buildup from the cartridges into
a clean bucket before proceeding. Remove hopper
from base and place on a clean surface.
Note: Always add acid to water. Never add water to
acid as splattering will occur resulting in possible
injury.
3. Fill a small plastic bucket (4-6” diameter) with
1 pint of water. Slowly pour 3 ounces of Muriatic
acid into the bucket. Place one cartridge (grid
down) at a time in the bucket to dissolve scale on
the cartridge grid. Remove when the scale on the
grid is gone and rinse with water. Repeat procedure
for all scaled cartridges using the same acid
solution.
4. Lift the dissolving cup out of the way pouring the
contents into the base carefully. Rinse off and soak
in dilute acid solution in a bucket if necessary to
remove scale.
5. Pour the solution from the discharge tank slowly
into the bucket used in step 2 for rinsing the
cartridges and add 1 gallon of fresh water to
discharge tank.
6. Add 1 cup of Muriatic acid to the discharge tank to
dissolve the scale. Let sit until scale is gone.
7. Pour the solution from bucket used in Step 3 into
the discharge tank. Rinse out bucket with water
and store for future use.
8. Place the Tablet cartridges back into the hopper.
The solution from the Discharge tank will clean
the discharge valve, tubing and venturi (if present)
when system is restarted.
9. Replace the dissolving cup and put the hopper back
on the base.
10. Open inlet and outlet shut off valves to the Feeder.
11. Place the tablets from the bucket back into
Cartridge(s). Adjust inlet flow to desired setting.
12. Dispose of chlorinated solution from steps 2 & 5 in
skimmer, gutter or pool (when not in use).
