WARNING
Failure to heed the following warnings can result in
permanent injury, electrocution or drowning.
ELECTRICAL HAZARD
• To reduce risk of electrical shock
- Make sure all power to pool equipment area is off prior to any installation or removal of Clearwater
components.
- Replace damaged power pack cord immediately.
- Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers and other
equipment.
• Severe shock or injury will likely occur as a result of a drill or drill cord coming in contact with water.
Never allow electric drill or cord to come in contact with water. Only plug drill into a Class A (5
Milliampere Trip) protected Ground Fault Circuit Interrupter (GFCI) in accordance with the National
Electrical Code Section 680 (USA only). Please see your drill owner’s manual for further safety
precautions.
• Install the power pack at least 10 feet from the inside walls of a pool to prevent any possibility of the
unit coming in contact with water.
• Your Clearwater Chlorinator has been designed with an electronic flow switch. This device automatically
switches the chlorinator ‘OFF’ when the water through the cell stops.To prevent cell damage and
personal injury, do not in any way interfere with this system which has been designed for your
protection.
CHEMICAL USE HAZARD
• To avoid personal injury when working with pool chemicals, always wear rubber gloves and eye
protection and work in a well-ventilated area. Use caution when choosing a location to open and use
chemicals as they may damage any surface in which they come in contact.
• The addition of certain chemicals can reduce the effectiveness of chlorine. Always make sure that proper
residual chlorine levels are maintained to avoid personal injury.
• This product manufactures chlorine. Individuals with any type of chlorine sensitivity should take the
appropriate precautions to avoid injury or illness.

SAFETY INSTRUCTIONS
EQUIPMENT WATER PRESSURE HAZARD
• Always turn pump off prior to installing or removing any Clearwater cell. Your pump/filter system is
operated under pressure and the pressure must be released before you begin work. Please see your
pump/filter owner’s manual for further instructions.
• To avoid cell damage, water pressure in the cell must not exceed 40 psi.
PREVENT CHILD INJURY AND DROWNING
• To reduce the risk of injury, do not permit children to operate this product.
• Do not let anyone, especially small children, sit, step, lean, or climb on any equipment installed as part of
your pool’s operational system. Unless otherwise stated, ALL components of your pool's operational
system should be located at least 3 feet from the pool so children cannot use the equipment to gain
access and be injured or drown.
!
CAUTION
Failure to heed the following warnings could cause
damage to pool equipment or personal injury.
• Chlorinator must be installed and operated as specified.
• Scratching or bending plates in cell housing can reduce cell life.
• Power to the C Series should be turned off before unplugging the cell connectors to prevent cell damage
and low voltage sparks.
• Keep the cell terminals protected with a light coating of silicone grease to allow for a positive electric
connection. Use of any other type of grease may damage the terminal seals and ‘o’ rings. Do not
immerse these terminals in acid wash solution, and avoid accidental contact with salt water.
• Water above the temperature of 104 degrees F (40 degrees C) flowing through the cell can cause plastic
cell to discolor.
• Power pack must not be installed directly above any other heat source such as filter, pump or heater. It
must be at least 1 Ft. (300 mm) from the ground to allow free circulation of air around it. It must not
be installed in a closed box. If the power pack is to be installed on a post, then it must be centrally
positioned on a flat panel of suitable waterproof material at least 10 inches (240mm) wide and 18 inches
(440mm) high.
• Check the cell frequently to prevent the accumulation of pool debris that for any reason may have bypassed the pool filter.

ZODIAC C-SERIES INSTALLATION
Zodiac C-Series Installation
Zodiac salt water chlorinators must be installed by a qualified swimming pool
professional or certified electrician. If you need assistance in finding a qualified installer
please contact our technical service department at 1-888-537-6657.
Installing the cell.
The Zodiac cell MUST be installed horizontally, with the ports down, as the last
piece of pool equipment in line. (The design of the cell forms a natural gas trap. Even
though the C-Series has an internal flow sensor, this installation provides a secondary safety
feature to prevent gas build-up within the system.) There are no height restrictions or
requirements. The cell should be installed within 5’ of the power pack. Unions and adaptors
are provided. Water can flow in either direction without affecting performance. 11/2" or 2"
sch 40 rigid PVC is required. Any standard PVC cement may be used. Allow adequate drying
time before turning on the chlorinator. If you choose to isolate the cell, we recommend that
you use a check valve and NOT a manual or automatic valve between the Zodiac chlorinator
and the return back to the pool.
Important:
•
•
The water pressure in the cell must not exceed 40 psi.
The water temperature in the cell must not exceed 104˚ F.
Flooded Plumbing Installation
This occurs when the water level of the pool is above the height of the pool equipment. Some
pool systems may have valves that will isolate the equipment. If not, one ball valve should be
installed on the inlet side of the cell and a one-way check valve should be installed on the
outlet side of the cell.This will eliminate the possibility of having a gas build-up and possible
cell damage.
Multiple Installations
If conditions require multiple installations the C-Series chlorinator may be plumbed in either
series or parallel providing that the header or manifold is balanced, providing equal flow to
each chlorinator.
7
Installing the Power Pack
Do not install it above any heat source. Install the Power Pack a minimum of 3 feet from the
pool edge. See your local building codes for requirements. It is preferable, but not essential, to
place it in a shady area, sheltered from the rain and direct sunlight. Do not store chemical
products near the casing.
The Power Pack is hard-wired to 220V ONLY. It should be wired to the "LOAD" side of the
pump timer or the pump circuit of a controller, so that the Zodiac chlorinator comes on only
when the pump comes on.
Connecting the Power Pack to the Cell
Connect the power cable to the electrode terminals. Red with red and black with black. Clip
the thinnest supply cable to the small terminal on the cell. Make sure the connections are
firmly attached.
Salt
Always test the salt level before adding salt. Refer to page 18 & 19 for instructions on
adding salt.
8
Installation Safety
If you choose to isolate the cell, we recommend that you use a check valve and NOT a manual
valve between the Zodiac chlorinator and the return back to the pool.

After installing the Zodiac chlorinator the following safety test MUST be performed. Turn on
the pool pump and the chlorinator. Adjust the chlorine output to maximum. Disconnect the
small black sensor from the electrodes. The RED "no flow" light should be illuminated and
the chlorine output indicator should drop to the minimum. If this happens, the flow sensor is
operating properly. Reconnect the sensor to the electrode and resume normal operation. Do
not operate the unit if it fails this test. Contact Zodiac at 1-888-537-6657 for
instructions.

HOW YOUR ZODIAC C-SERIES CHLORINATOR WORKS
How your Zodiac C-Series
Chlorinator Works
Common salt (sodium chloride) is made up of two elements, sodium and chloride.When your
Zodiac C-Series is installed, a measured quantity of salt is dissolved in the pool water to make
it slightly salty. As part of the daily filtration cycle, the pool water is passed through the Zodiac
electrolysis cell to produce chlorine which is dissolved instantly into the water. Your C-Series
also produces ozone in the cell as a by-product.
In simple, non-technical terms, the chlorine instantly starts to destroy bacteria and algae, and in
doing this reverts to dissolved salt.This cycle continues with more new chlorine being
produced from the salt water in the electrolysis cell, sanitizing the pool, and changing once
more back to dissolved salt.
Everyday, when the Zodiac unit and the filtration system are switched on, dust and debris are
trapped by the filter and the C-Series sanitizes the water to make it sparkling clean.
Important
To ensure your C-Series works at maximum efficiency, regularly check and maintain the
chemistry of your pool.

INDICATOR LIGHTS – WHAT THEY MEAN
Indicator lights:
What they mean
To protect your pool and it’s equipment, there is an electronic flow switch in your chlorinator
power pack which automatically switches the chlorinator “OFF” when water flow ceases, In
addition there is an electronic circuit which automatically tests the electrodes for calcium
build-up and the water concentration.
Meter readings – what they mean.
The meter reading shows that chlorine is being produced. It does not measure the amount of
chlorine in the water. If your meter is reading well below maximum, your cell may need
cleaning or more salt may be needed. See “Salt, how to add it, and how much to add”. See also
Problem J in “Problems that you may encounter.”
Red Indicator Light ON
This light indicates that the water flow is low, or has stopped and the chlorinator is OFF.
When water flow resumes, the chlorinator automatically switches on and the red light goes off.
Yellow Indicator Light ON
This light indicates that either the cell electrodes require cleaning, or the salt concentration in
the pool water has dropped or the water is very cold.
Green Indicator Light ON
This light indicates that the power pack is providing electrical power to the cell to produce
chlorine.

OPERATING TIPS
Operating Tips
A. Filtration and chlorination system operating periods.
Run your filtration and chlorination system for at least 6 to 8 hours per day.
For best efficiency, operate the system in the cool hours of the evening, or the early morning.
During very hot weather it might be necessary to run the system for additional hours, but in
winter where pools remain open, it is only necessary to run the filtration system for around 4
hours per day. Shorter periods will help to lengthen the life of the cell electrodes.
B. Chlorine output settings.
Make sure that your adjust the chlorine output of your C-Series to 80% or more. If you can not
achieve this output, the salt concentration is probably low, and more salt should be added to the
pool. Refer to ‘Salt:When And How To Add It’ and the ‘Adding Salt Chart’ on pages 17-18.
C. Free (residual) chlorine reading.
The free chlorine residual in the pool should be between 1 - 3 ppm. Increasing the daily
operating period of the system increases the free chlorine reading, and a shorter operating
period reduces the chlorine reading. Likewise, operating the chlorinator with an output reading
of 100% will produce a higher chlorine reading than operating the chlorinator at a lower
setting of, say, 50%.
D. Chlorine stabilizer (Cyanuric acid) level.
The chlorine stabilizer (cyanuric acid) reading should be between 40-100 ppm. This will vary
depending on your regional climate. Chlorine stabilizer helps to keep a satisfactory free
chlorine reading in hot sunny climates. Extremely hot and sunny climates will require readings
at the higher end of the given range. Refer to ‘Stabilizer Chart’ on page 19.
E. pH readings.
It is ABSOLUTELY ESSENTIAL that the pH of the pool be maintained in the range of 7.2 - 7.6.
The effectiveness of chlorine as a sanitizer is significantly reduced as the pH rises. At a pH of
8.0, nearly all of the chlorine being added to the pool is wasted, and it will be almost
impossible to maintain a satisfactory free chlorine reading.
15
OPERATING TIPS
F. Regular maintenance checks.
Weekly:
•
•
•
•
•
Visually check the cell electrodes. Only if necessary, remove the cell and flush with a garden
hose to remove any debris that may have passed through the filter and lodged in the cell
housing. Avoid inserting objects into the cell which can scratch or bend the cell plates.
Check the free chlorine.
Check the total alkalinity. Adjust if necessary.
Check the pH of the water. Adjust if necessary.
Check the pressure gauge on the filter to see if backwashing is necessary.
Monthly:
•
•
Check the salt concentration of the pool (see ‘Salt:When And How To Add It).
Check the chlorine stabilizer reading. Adjust if necessary.
16
SALT:WHEN & HOW TO ADD IT
Salt: When And How To Add It
When to add salt.
Turn the chlorine output control to maximum. If the chlorine output cannot reach at least 80%
(preferably 100%), it is a strong indication that additional salt is required. Refer to Problem J on
page 26.
The salt concentration should normally be around 4000 ppm, but should never be allowed to
fall below 3000 ppm, as this can reduce the life of the cell electrodes.
Salt is not lost through evaporation. Salt is lost with the water splashed out of the pool or
during backwash. Adding fresh water or rainfall to the pool dilutes the salt concentration.
Adding salt may be needed from time to time to maintain an optimum salt level.
How much to add.
Use a salt test strip to determine salt level in pool water prior to adding any salt. Capture
water from elbows depth in a container, then use a test strip in this water sample. Previous
regular usage of sodium hypochlorite (liquid chlorine) creates residual salt within the pool and
may bring your salt level close to the required 4000 ppm concentration. Only 99.5% pure
refined salt (sodium chloride) should be used with the Zodiac chlorinator. Avoid using salts
which contain yellow prussate or anti-caking additives which may cause staining. Add enough
salt to obtain a 4000 ppm concentration.
- In a pool of approximately 13,200 gallons, one (1) 50 lb. bag of salt will increase the salt
concentration by 500 ppm.
- In a NEW pool (where there is no salt residual) of approximately 13,200 gallons, eight
(8) 50 lb bags of salt are required to reach a 4000 ppm concentration.
- Refer to ‘Salt Chart’ on page 18.
IMPORTANT:To avoid damage to your Zodiac chlorinator, never allow
salt level to exceed 13,000 ppm
How to add salt.
Disperse the proper amount of salt around the perimeter of the pool. Brush the salt to spread it
evenly. Run filter for 4-6 hours. Allow 24 hours for salt to fully dissolve.Turn the chlorine output
control to max. and observe the meter, which will show a higher reading than before adding the
salt.The reading should be at least 90%. If not, add more salt using the same procedure. Always test
the salt level before adding additional salt.
If, after adding more salt the meter reading has only increased slightly, the cell could be
approaching the end of its useful life. Refer to Problem J on page 26.
Note: Do not add salt to the skimmer box.

SOME TIPS ON WATER CHEMISTRY
Some Tips On
Water Chemistry
How to adjust pH.
A pH range of 7.2 - 7.6 is ideal for maximum comfort and minimum chlorine demand. Always
adjust total alkalinity before adjusting pH.
Low pH (acidic water) leads to stinging eyes and corrosion of open metal fittings. Raise the pH
by adding sodium bicarbonate or soda ash. Consult your pool professional regarding which
chemical is best for your situation and the proper amount to use. Check the pH after 4 hours
of circulation, adjusting as necessary to achieve the proper range.
High pH (alkaline water) leads to clouding of the water and reduces the amount of active
chlorine.This means algae and germs can grow. Lower the pH by adding muriatic acid to the pool
water.The acid demand indicated by your 4-in-1 test kit will show the amount of acid to use.
If your pH remains inconsistent, check your total alkalinity.
Total alkalinity affects pH.
Total alkalinity is a measure of the alkaline chemicals in your pool water (eg. Bicarbonates,
carbonates, and hydroxides). It can be thought of as the buffering system necessary to control
pH. Low alkalinity can be compared to weak shock absorbers on a car, allowing pH to
fluctuate.The pH will be difficult to maintain and staining of pool surfaces may occur when
total alkalinity is too low.
Total alkalinity should be in the range of 80 - 120 ppm.Total alkalinity is often confused with
pH, which it affects.
To raise total alkalinity, add pH buffer (sodium bicarbonate) at the rate shown in the
manufacturers instructions to achieve a reading in the 80 - 120 ppm range. 1.5 lbs. of sodium
bicarbonate raises 10,000 gallons of pool water by 10 ppm.
To lower the total alkalinity, use muriatic acid.The acid demand chart in your 4-in-1 test kit will
indicate the necessary amount to add.Adjust as needed until the reading (taken at least 24
hours later) is in the 80-120 ppm range.When total alkalinity is correct, you may need to
adjust pH.

SOME TIPS ON WATER CHEMISTRY
Use of algaecides and phosphate removers
Although not normally needed, algaecides and phosphate removers may be used in conjunction
with a Zodiac chlorinator. Consult your pool professional regarding the presence of phosphates in
your local area and always follow manufacturers instructions for treatment.
Chlorine residual level maintained with a Zodiac chlorinator is the best defense against algae and is
usually all that is necessary. If algae is observed however, brush spot thoroughly, adjust pH, superchlorinate with your Zodiac chlorinator or manually shock pool water with either liquid or
granular chlorine. A chlorine residual should be measurable within 24 hours. If not, repeat shock
treatment (see pages 22-23 for additional water balance instructions). After shocking, check to
ensure that the Zodiac chlorinator is maintaining a residual chlorine level to prevent future algae
growth.With extreme algae conditions, manually shocking the pool is the best option.
Note: Overuse of algaecides can lead to a reduction in chlorine residual because algaecides
can negatively react with the chlorine produced by the Zodiac chlorinator.When using
algaecides, always follow manufacturer's instructions and adjust the output of the Zodiac
chlorinator to maintain a residual chlorine level.
The addition of certain chemicals can reduce the effectiveness of chlorine. Always
make sure that proper residual chlorine levels are maintained to avoid illness.
Use of sequestoring agents
In some areas the total hardness of your source water may be unusually high. High total
hardness contributes to scale formation in the pool. Sequestoring agents will help keep minerals
in solution, preventing this from happening. Consult your pool professional about the use of a
sequestoring agent.

TROUBLESHOOTING
Troubleshooting
NOTE: If the chlorinator and pump are running it is normal for a cloud of small bubbles to
be produced in the cell, indicating chlorine is also being produced.
Problem A
Water looks clean but no chlorine residual reading.
To test for chlorine residual, switch on the filtration system and adjust the C-Series to
maximum output.After a few hours take a water sample from the pool.Test this water with
your test kit. Chlorine residual should measure between 1 and 3 ppm.
REMEDY:
•
•
•
•
•
•
Adjust total alkalinity to 80 - 120 ppm.
Adjust the pH within the range 7.2 - 7.6.
Make sure your cell is clean.
Check cyanuric acid levels.
Increase the setting of the output control.
Increase the running time of the filter and chlorinator. Make sure that the filter is clean and
functioning properly.
Use chlorine stabilizer (cyanuric acid) to protect chlorine residual.
This chemical acts as a sun-screen for chlorine and prevents chlorine from being too quickly
destroyed by the sun. Chlorine stabilizer is essential to prolong the life of chlorine in the pool
water. It should be added following the manufacturer’s instructions to achieve a level of 40 100 ppm. depending on geographical climate. Refer to stabilizer chart on page 19.
Use of algaecides.
Although not normally needed with a Zodiac chlorinator, algaecides may be used. Always
follow manufacturer's instructions for treatment. Overdosing the pool with any type of
algaecide may reduce residual chlorine measurements/reading. If this occurs, you must
manually shock pool water with granular or liquid chlorine until a measurable free chlorine
residual reading is obtained.
22
TROUBLESHOOTING
Problem B
Pool green and no chlorine reading.
Chlorine is still considered the most effective way of destroying algae and bacteria in your pool
water. A chlorine residual of 1 to 3 ppm is considered desirable.
REMEDY:
Superchlorinate or manually shock the pool. This will raise the chlorine residual to a very high
level for a short period of time, and reduce chlorine demand.
1.
Superchlorinate with a C-Series chlorinator:
i)
Backwash the filter.
ii)
Adjust the pH to within the range 7.2 - 7.6. See ‘Tips on Water Chemistry’ on pages 20-21.
iii) Turn the C-Series to maximum output and run the filter and the chlorinator for 24 hours
continuously. over-ride the time switch if one is fitted.
iv) After 24 hours, backwash the filter.
v)
Re-adjust the pH to 7.2 - 7.6.
vi) Check the chlorine reading.
vii) If the chlorine reading is too low, repeat steps (iii) to (vi) until the chlorine reading
is satisfactory.
2.
Manually shock with chlorine or oxidizing agents:
i)
Backwash the filter.
ii)
Adjust the pH to within the range 7.2 - 7.6 (See ‘Tips on Water Chemistry’ pages 20-21).
iii) Add 1 lb. granular chlorine or 1 gallon liquid chlorine or 1 lb. non-chlorine oxidizer per
10,000 gallons of water.
iv) After shock dosing, re-adjust the pH to within the range of 7.2 - 7.6 and check the
chlorine level before using the pool.The chlorine residual should be 1-3ppm..
23
TROUBLESHOOTING
Problem C
Chlorine odor.
CAUSE:
Not enough free chlorine.
Surprisingly, the problem here is not too much chlorine as many imagine. Chloramines form by
the bonding of chlorine with amines from sweat and other sources.These chloramines can
create a chlorine odor and can also cause eye and skin irritation. Free chlorine does not smell
(up to 10 ppm concentration).
REMEDY:
Same as problem B.
Problem D
Slimy walls of pool or spa.
CAUSE:
Combined algae and bacteria growth.
REMEDY:
Brush down the affected walls and follow remedy for Problem B, manually shocking pool.
Problem E
Eye and/or skin irritation.
CAUSE:
Incorrect pH.
REMEDY:
Adjust the pH to within the range 7.2 - 7.6 (See ‘Tips on Water Chemistry’ pages 20-21).
Problem F
Scale formation on pool equipment.
To clean the deposit (scale) from the cell, see Chlorinator Maintenance section.
CAUSE 1: Incorrect pH and hard water.
REMEDY:
Adjust the pH to within the range 7.2 - 7.6 (See ‘Tips on Water Chemistry’ pages 20-21).
CAUSE 2: High total hardness.
REMEDY:
Dilute pool with fresh water. Consult your pool professional regarding use of a sequestering
agent.
24
TROUBLESHOOTING
Problem G
Power Pack red light “ON”.
CAUSE 1: This is the flow indicator showing insufficient water flow through the cell.
REMEDY 1:
Ensure sufficient water flow through chlorinator cell. Is the filter pump on? Is flow restricted
because the filter needs backwashing? Look for a pocket of air trapped in the top of the cell.
This would confirm one of the problems just mentioned. e.g. low water flow through the cell.
Insure the pool filter is clean.
REMEDY 2:
Make sure that the sensor lead from the power pack to the cell (the thin black lead) is firmly
attached to the cell.
Problem H
Chlorinator stops working, all lights “OFF”.
CAUSE: Time switch in OFF mode.
REMEDY:
Adjust time switch.
Problem I
Power Pack yellow light “ON”. Chlorine output meter reads low.
CAUSE 1: Chlorine control output set too low.
REMEDY: Turn control up.
CAUSE 2: Cell needs cleaning.
REMEDY: Clean cell.
CAUSE 3: If cell is clean, not enough salt in the pool water.
REMEDY: Add salt according to instructions.
CAUSE 4: Damaged electrodes.
REMEDY: Replace electrodes.
CAUSE 5: Low water temperature in winter.
REMEDY: Check again during summer.
25
TROUBLESHOOTING
Problem J
Reading on chlorine output meter cannot be set to 100%.
CAUSE 1: Salt concentration too low. It should be 4,000 ppm to allow output to reach 100%.
REMEDY:
*Add two large handfuls of salt to the skimmer box while the system is running. Make sure that
the output control is turned to maximum, and observe the chlorine output meter. If low salt
concentration is the cause of the low meter reading, the meter pointer will start to rise after
about 20 seconds, and should rise up to the maximum reading on the meter and then slowly fall
back to its original reading.This test proves that the low reading is due to low salt
concentration. Disperse (1) 50 lb. bag of salt evenly around the perimeter of the pool.
* Note: Do not add salt directly through the skimmer box except for
this test.
CAUSE 2: Chlorinator cell is failing. If the previously described test of adding handfuls of salt to
the skimmer box makes little difference to the meter reading, the cell may be close to failure.
REMEDY:
Contact your Zodiac Service Technician or your pool shop to have the cell tested.
CAUSE 3: Cell is covered in white coating (calcium deposit).
REMEDY:
Refer to ‘Chlorinator Maintenance’ on page 27.
CAUSE 4: Cold water during winter.
REMEDY:
Check again when water warms up.
Any type of electrical troubleshooting should be handled by a
qualified pool professional or certified electrician.

CHLORINATOR MAINTENANCE
Chlorinator Maintenance
Check and clean your cell regularly.
Initially, check your cell every week for deposit (or scale) on the electrodes.This will enable
you to determine the cleaning period. All salt chlorinator cells must be cleaned before scale
builds up to the point where the electrode gaps in the cell are bridged. If the cell operates with
deposit bridging the electrode gaps it can be irreparably damaged and the electrodes may have
to be replaced.
How to clean your cell.
1. Switch off the filter pump and chlorinator and disconnect from the power outlet, close
necessary valves.
Note:Always turn pump off prior to installing or removing any Zodiac Cell. Your
pump/filter system is operated under pressure and pressure must be released
before you begin. Open the air relief valve on your pool filter to release the
pressure in the system.
2. Unplug the leads from the cell terminals.
3. Unscrew the large ribbed plastic nut, and carefully withdraw the electrodes.

4. Direct a fast water jet from the garden hose onto electrode to clean or mix cleaning
solution in a suitable plastic vessel by adding one (1) part of Hydrochloric (muriatic) acid to ten
(10) parts water. Note:To avoid splash, always ADD MURIATIC ACID TO WATER
rather than water to muriatic acid. Solutions stronger than 1:10 will damage cell
and void warranty. Immerse the electrodes (but not the terminals) in the cleaning solution.
Allow the cleaning solution to dissolve the calcium deposits for approximately 5 minutes. Rinse
electrodes in clean water and re-install. Cleaning solution can now be disposed of down a drain.
Note: Never mix chemicals together.Always rinse bucket and drain area after
cleaning cell.
To avoid personal injury when working with pool chemicals, always wear rubber
gloves and eye protection and work in a well ventilated area. Use caution when
choosing a location to open and use chemicals as they may damage any surface in
which they come in contact.
5. Replace electrical connections.
6. Reset valves and switches.Turn pump and chlorinator on.
7. Check meter reading on power pack.
8. Use only silicon greases with cell plastics. Do NOT lubricate terminals.
Your Zodiac Chlorinator has been designed with an electronic flow switch.This
device automatically switches the chlorinator “OFF” when water through the cell
stops.To prevent cell damage and personal injury, do not in any way interfere with
this system that has been designed for your protection.
Damage caused by insects.
The case of the C-Series power pack has small vents to allow internal components to remain
cool in hot weather. Sometimes small insects may enter the case of the power pack, and this
can cause damage to the internal electrical components.To avoid this, spray some insect
repellent on surfaces around the powerpack.
