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.
