FORWARD
The Operator’s Guide has been pre-
pared to acquaint the owner/opera-
tor with this water ltraon unit, its
various controls, maintenance and
safety instrucons. It is valuable for
the proper use of The Flex-Chlorina-
tor and should be kept with the unit
at all mes.
Make sure you read and under-
stand the content of the Operator’s
Guide.
For any quesons pertaining to the
warranty and its applicaon, consult
the WARRANTY secon in this guide
and/or a First Water representave.
The informaon and component de-
scripons in this guide are accurate
at the me of wring.
The illustraons in this guide repre-
sent the typical assembly and op-
eraon of the unit, but may not rep-
resent the full detail or exact shape
of the parts.
It is understood that this guide may
be translated into another language.
In the event of a discrepancy, the
English version shall prevail.
Specicaons are given in the SAE

Operaon and Maintenance Safety
NEVER posion the Flex-Chlorinator directly over the Chlorine Diluon
Container. The sucon hose from the Chlorine Diluon Container to the
Flex-Chlorinator should fall below the top of the container, then rise back
up to the injector (see installaon diagrams).
NEVER leave the Flex-Chlorinator or water lines full of water during freez-
ing temperatures. Visually inspect the Flex-Chlorinator and water system
for leakage.
Warning! Risk of Chemical Overdose
To reduce risk, follow proper installaon methods and instrucons. The
point of chemical injecon should be beyond all pumps, lters and heat-
ers.
NEVER use chlorine with fragrance, perfume of detergent addives.
Noce:
This injecon system and its components have been tested for use with
Sodium Hypochlorite (5-15%).
The Flex-Chlorinator provides a means of delivery for chemicals in gen-
eral. First Water Systems, Inc. does not suggest or recommend ways or
procedures for using any chemical.
First Water Systems, Inc. is not responsible for injury incurred by the mis-
use or improper handling of chemicals.

Chemical Preparaon
The presence of chlorine residual in drinking water indicates that:
1) a sucient amount of chlorine was added inially to the water to inac-
vate the bacteria and some viruses that cause diarrheal disease; and
2) the water is protected from recontaminaon during storage.
The presence of free residual chlorine in drinking water is correlated with
the absence of disease-causing organisms, and thus is a measure of the
potability of water.
The recommendaons of the CDC Safe Water System (SWS) are as fol-
lows:
1. At 30 minutes aer the addion of sodium hypochlorite there should
be no more than 2.0 ppm of free chlorine residual present (this ensures
the water does not have an unpleasant taste or odor).
2. At 24 hours aer the addion of sodium hypochlorite to containers
that are used by families to store water there should be a minimum of 0.2
ppm of free chlorine residual present (this ensures microbiologically clean
water).
Further, the CDC Safe Water System recommends tesng residual chlo-
rine by the following methods:
1. Pool test kits
2. Color wheel test kits
3. Digital Chlorimeters

Note: This informaon is provided as a courtesy of First Water Systems,
Inc. First Water Systems, Inc. does not suggest or recommend ways or
procedures for using chlorine in drinking water. Local regulaons should
be consulted before the use of chlorine in drinking water.

Chemical Preparaon
The Flex-Chlorinator is designed to inject a chlorine diluon into your
water supply to provide a residual amount of chlorine in your water.
Because First Water Systems can not guarantee the quality of water going
through the Flex-Chlorinator, the following guidelines are for the total
chlorine demand of your water, not the nal desired residual chlorine.
1. Open the case and remove the Chlorine Diluon Containers.
2. Follow the chart below to achieve the proper diluon of household
bleach. CAUTION: never use bleach with fragrance, perfume, detergent
or any other addives.
3. Posion the Flex-Chlorinator in line with your water treatment sys-
tem aer all pumps, lters and heaters; before your distribuon/storage
point.
4. Place the Chemical Pump Sucon Tube into the Chlorine Diluon Con-
tainer.
5. Make appropriate connecons as shown on the next page.

Operaon
Starng the Unit
1. Be sure the chemical pump is locked into the boom of the water mo-
tor. (1/4 turn to the right).
2. Open any valves between the Flex-Chlorinator and distribuon points.
3. Open any valves between the water source and the Flex-Chlorinator.
4. Open air vent unl all trapped air is released.
5. Warning! The Chlorine Diluon Container must be connually moni-
tored to ensure your water treatment system does not connue to oper-
ate aer the chlorine soluon is depleted.
6. When the water motor is working properly, you should hear a clicking
sound.
Stopping the Unit
1. Close any valves between the water source and the Flex-Chlorinator to
stop the ow of water.
2. Close any valves between the Flex-Chlorinator and water distribuon
points.

Installing the Pump to the Water Motor
1. Lubricate “O” rings on pump
housing with any food grade lubri-
cant when pump is removed from
motor.
NOTE: a light coang of lubricant is
all that is required.
2. Make sure the pump stem is
pulled all the way out (about 2”).
Push the pump up into the water
motor, and turn 1/4 turn clockwise,
port to front.
NOTE: the guide slot must be
aligned to t into the key on the
inside of the water motor.
3. Aer installing pump into boom
of water motor - loosen Jaco nut on
pump and insert hose into ng.
Re-ghten Jaco nut.
1. Make sure the water is turned
o, and water pressure in the water
motor is released - this is done by
loosening the Air Vent (pressure
relief valve) on the top of the water
motor and turning o the water
ow.
NOTE: Do Not Remove Air Vent.
2. Turn pump counter clockwise
1/4 turn, then pull down.
NOTE: always disconnect hose from
pump before removing.

Pump Motor Diagram:
Problem: Water Motor does not click. Water does not ow past unit.
• Cause: No water ow to motor.
• Soluon: Check that water is owing to Flex-Chlorinator.
• Cause: Incoming water is connected to the outlet side of the pump
motor.
• Soluon: Verify that the incoming water is connected to the inlet
(right side) of the pump motor.
Problem: Water Motor does not click. Water does ow past unit.
• Cause: Water motor is in “bypass” due to damaged parts on the in-
side of water motor or excessive wear of moving parts.
• Soluon: Contact First Water for support.
Problem: Motor click a few mes then stops.
• Cause: Unit is in bypass condion.
• Soluon: Shut o water. Relieve pressure at the air vent. Restart wa-
ter.
• Cause: Clogged chemical feed tube.
• Soluon: Inspect tube for blockage.
• Cause: Motor may be in bypass due to damaged internal parts.
• Soluon: Contact First Water for support.
• Cause: O-Ring on pump stem may have excessive wear.
• Soluon: Contact First Water for support.

Problem: Motor clicks, but chlorine is not drawn up the sucon hose.
• Cause: Pump cap is loose.
• Soluon: Hand ghten pump cap.
• Cause: Pump stem is not engaged into the piston clip in the water mo-
tor.
• Soluon: Remove pump, check for broken or worn pump stem at p.
Pump stem must be pulled out completely before being inserted into
the water motor.
• Cause: Damaged pump.
• Soluon: Contact First Water for support.
Problem: Chlorine is drawn up in the sucon hose, but them falls back
down.
• Cause: Vacuum leak.
• Soluon: Check sucon hose to ensure a ght t. Prime pump by
hand and verify that the soluon stays up in the sucon hose.

Water Motor
1. Do not let unit freeze.
2. Periodically clean or replace chemical hose (hose between pump &
water motor) and connectors. Chemical buildup will cause the unit not to
pump.
3. If chemical pump becomes hard to remove from boom of water mo-
tor, clean inside of opening on boom cap of water motor with tooth-
brush & white vinegar.
Chemical Pump
1. Clean pump aer use by running 5 gallons of clean water through the
pump, or by removing the pump and hand cleaning individual parts.
Other
1. Keep your stock soluon bucket clean of foreign parcles and trash.
2. Keep the sucon hose lter o the boom of the stock soluon bucket,
insoluble parcles may cause clogging and accelerate wear.
