MODELS
C250CF, C500CF, C1100CF, C1800CF, C2400CF
Your Hayward Automatic Chemical Feeder is designed for installation next to
filter/pump system. It uses either Trichloro-S-Triazinetrione (tri-chlor) slow
dissolving chlorine or bromine sticks or tablets ONLY. No other type of
chemical should ever be used in your feeder. It should be installed to operate
by the pressure differential of the system, or a pressure-suction combination,
using the pump to provide water flow through the feeder. The amount of
sanitizer dissolved depends on the flow rate through the feeder. By
regulating the Dial Control Valve between FULL (more sanitizer) and toward
OFF (less sanitizer), you can easily adjust the rate of feed necessary to
maintain the proper residual for your pool.
DANGER—READ CAREFULLY
Always read label and carefully follow the sanitizer
manufacturer’s and dealer’s recommendations for proper
water conditioning and daily sanitizer requirements for your
particular pool. This chemical feeder is designed to use only
either Trichloro-s-Triazinetrione (tri-chlor) slow dissolving
chlorine or bromine sticks or tablets. NEVER MIX or use any
other types of chlorine sanitizer or chemicals in this feeder.
Explosion or fire may result, causing property damage,
personal injury or death.
WARNING: MISUSE MAY RESULT IN SERIOUS
PERSONAL INJURY REQUIRING HOSPITALIZATION.
RELATED COMPLICATION MAY LEAD TO DEATH.
Exercise extreme caution when opening or servicing your
feeder. Always shut off pump and available valves before
opening feeder. NEVER OPEN chemical feeder when pump
is running. Do not inhale fumes from any chemical feeder or
container. Protect your eyes, skin and clothing from
chemicals at all times with gloves and face shield. To
prevent build up of gas in chemical feeder, be sure return
line valve(s) is kept open—except when opening/servicing
unit.
WARNING: IF THESE INSTRUCTIONS ARE NOT
FOLLOWED EXACTLY, A FIRE OR EXPLOSION MAY
RESULT, CAUSING PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
For proper installation of your Chemical Feeder, see
Installation Instructions on next page.
BROMINE USE:
Before start-up of your chemical feeder, your pool should be
properly conditioned and have the recommended bromine
residual as listed below. The chemical demand for pools
varies based on use, temperature, sunlight, etc. Initially,
you’ll have to experiment to determine the proper valve
setting required for your pool and filter time cycle. As a start,
add desired quantity of bromine tablets or sticks, slow
dissolving type only, and set Dial Control Valve at 1/2. Test
water periodically and adjust Dial Control Valve setting to
maintain a proper bromine level.
Recommended Bromine Residual:
CHLORINE USE:
Before start-up of your chemical feeder, your pool should be
properly conditioned and have the recommended chlorine
residual as listed below. The chemical demand for pools
varies based on use, temperature, sunlight, etc. Initially,
you’ll have to experiment to determine the proper valve
setting required for your pool and filter time cycle. As a start,
add desired quantity of chlorine tablets or sticks, slow
dissolving type only, and set Dial Control Valve between 2
and 4. Test water periodically and adjust Dial Control Valve
setting to maintain a proper chlorine level.
Recommended Chlorine Residual:
Residential Pools: 2.0 - 3.0 PPM
Commercial Pools: 3.0 - 5.0 PPM
Residential Pools: 1.0 - 2.0 PPM
Commercial Pools: 1.0 - 2.0 PPM

DESCRIPTION
Page 3
TO OPEN CHEMICAL FEEDER:
Shut off pump and turn Dial Control Valve to OFF. Wait
1 minute. (If outlet is below water level, close any other
in-line valves to prevent possible water back flow.)
Turn Cover Cap counter-clockwise to open. Use
SP3100T cover opening tool if necessary. Caution: Do
not inhale fumes from feeder. Allow water in tank to
drain automatically to pool. If chemical feeder is installed
below water level, open the Drain Valve and allow the
tank to drain in a safe manner. Draining the tank should
make adding sanitizer easier and safer.
TO REFILL CHEMICAL FEEDER:
Add desired quantity of either Trichloro-S-Triazinetrione
(tri-chlor) slow dissolving chlorine or bromine tablets or
sticks. NEVER mix chemicals together or use any other type
of chlorine sanitizer in this feeder. Explosion or fire may
result causing property damage, personal injury or death.
TO CLOSE CHEMICAL FEEDER:
Be sure cover O-Ring is in place. Engage cover threads
and turn clockwise to secure. Hand tighten only.
Place Dial Control Valve to desired setting. Open in-line
valves and re-start pump per manufacturer’s
instructions.
PRESSURE - PRESSURE INSTALLATION
This uses system pressure differential to divert water
through the chemical feeder into the return-to-pool piping
after the filter/heater. The inlet of the chemical feeder is
connected to the discharge side of the pump (before the
filter) and the outlet is connected after the filter (and heater
if installed). This creates a pressure-pressure piping circuit
through the feeder. If a heater is installed, a check valve
must be installed between the heater outlet and the
chemical feeder return. This will prevent a high
concentration of the sanitizing agent from back flowing into
the heater. This back flow can occur from a pressure
differential when the pump is shut off. If a high concentration
of sanitizer flows into the heater, it will cause the copper heat
exchanger to deteriorate and possibly leak. If this
happens, a fire or explosion may result causing property
damage, personal injury or death.
PRESSURE - SUCTION INSTALLATION
With this method, the inlet pipe of the chemical feeder is
connected to the discharge side of the pump (before the
filter); and the outlet is connected back to the suction
side of the pump (before the pump). This creates a
pressure-suction piping circuit through the feeder. Do not
use this installation method if a heater is installed in the
system. This method of installation allows too high of
concentration of sanitizer to pass through the system than is
safe for the copper heat exchanger of a heater. This
installation may cause the heat exchanger to deteriorate and
possibly leak. If this happens, a fire or explosion may result,
causing property damage, personal injury or death.

GENERAL INFORMATION:
Turn Dial Control Valve to OFF when vacuuming,
backwashing, or adding D.E. to filter, and when adding any
other chemical in concentrated form. Never use petroleum
type lubricants on cover O-ring. If lubrication becomes
necessary, use non-petroleum based lubricants such as
Jack’s No. 327 lube or Ivory®bar soap.
Flush tank once a week by opening Dial Control V alve to full.
Run for approximately 1 minute. Reset Dial Control Valve to
desired setting.
Close feeder Dial Control Valve when vacuuming,
backwashing or adding D.E. to filter, and when adding other
chemicals to your pool.
WINTERIZING:
Where freezing temperatures can be expected, drain all
water from feeder. Carefully remove any undissolved, damp
tri-chlor or bromine tablets or sticks. Rinse out chemical
feeder thoroughly with water. Replace Cover and engage
1-1/2 turns. Keep unit covered all winter to prevent entrance
or rain or snow.
