3.0 SAFETY INSTRUCTIONS
3.1 IMPORTANT SAFETY INSTRUCTIONS, READ AND FOLLOW ALL
INSTRUCTIONS. SAVE ALL INSTRUCTIONS.
3.1.1 WARNING: To reduce the risk of injury, do not permit children to operate this
device.
3.1.2 NOTE: One bonding lug is provided on the external surface of the CPSC Series
Chlorine Generator. Some local codes may require external grounding source.
Check your local ordinances.
3.1.3 WARNING: Heavy pool (and/or spa) usage, and higher temperatures may require
higher chlorine output to maintain proper free available chlorine residuals.
3.1.4 If additional chlorine is required due to heavy bather loads, use Sodium
Hypochlorite to maintain an appropriate chlorine residual in the water. NOTE: For
outdoor pools, chlorine residuals can be protected from destruction by sunlight by
addition of stabilizer (cyanuric acid).
3.1.5 Maintaining high chlorine and very high salt levels above the recommended range
can contribute to corrosion of pool (and/or spa) equipment.
3.1.6 The life of the electrolytic cell is 12,500 hours, under normal use conditions.
3.1.7 DO NOT add chemicals directly to the skimmer. This may damage the cell.
3.1.8 Check the expiration date of any test kits as test results may be inaccurate if used
after that date.

Compu Pool CPSC Series Manual 4
3.1.9 When replacing the cell, only use replacement cells having a label that clearly
states that it is a replacement cell for this model.
3.1.10 Follow all aspects of the local and National Electrical Code(s) when installing the
CPSC Series Chlorine Generator.
3.1.11 For proper sanitation, spas must be completely drained periodically. The number of
days between COMPLETE SPA DRAINAGE is equal to the volume of the spa
water in gallons, divided by 10 times the maximum number of daily spa users.
Refill spa with water and repeat DIRECTIONS OF USE of this device.
3.2 Health and Hyperthermia warnings for spa devices
3.2.1 People with a medical condition should consult a physician before entering pool or
spa water.
3.2.2 Maximum spa water usage temperature is 104°F. Bathing time in spa water at
104°F should not exceed 15 minutes.
4.0 THE CHEMISTRY INVOLVED
4.1.1 The CPSC Series Chlorine Generator by electrolysis creates chlorine to sanitize
your pool using the salt molecules (NaCL) in your water. A small electric charge is
applied across a set of titanium plates inside the Electrolytic Cell. This produces
Sodium Hypochlorite (NaOCl). In water, Sodium Hypochlorite dissociates into
sodium (NA+) and hypochlorite (OCl-) ions.
4.1.2 It is the hypochlorite ions that form with the hydrogen (H+) ions (from the water) to
form hypochlorous acid (HOCl), which is the active agent that destroys bacteria and
algae, and oxidizes organic matter. This form of chlorine works quickly in the pipe,
leaving only a mild residual in the pool.
5.0 WATER CHEMISTRY
5.1 WARNING: Prior to turning on your CPSC Series Chlorine
Generator for the first time (including reopening your pool for the
new pool season) your water chemistry must be balanced
according to the following guidelines.

5.2.1 Chlorine Stabilizer (Cyanuric Acid). Chlorine Stabilizer is needed to maintain
proper levels of chlorine. Unstable chlorine can be destroyed by the sun’s UV
radiation within two hours. Chlorine stabilizer must be maintained between 30 –60
ppm.
5.2.2 Nitrates and Phosphates. These chemicals can cause extremely high chlorine
demands and will deplete chlorine from your pool. In some cases, they may even
lower your chlorine levels to zero. Your local pool professional can test for Nitrates
and Phosphates.
5.2.3 Metals. Metals can cause loss of chlorine. Also, metals can stain your pool and tint
your water. Have your local pool professional check for metals and recommend
methods of removal.
5.2.4 Chloramines. Chloramines should not be present in pool water. When organic
materials are not fully oxidized by Free Chlorine, Chloramines are formed. This ties
up the Free Chlorine in your pool, and does not allow the chlorine in your pool to
disinfect. Chloramines also cloud pool water and burn the eyes. Shock the pool
with chlorine to remove Chloramines at the initial startup of the pool.
5.2.5 pH Levels. pH produced by a chlorine generator is close to neutral pH. However,
other factors usually cause the pH of the pool water to rise. Therefore, the pH in a
pool chlorinated by a chlorine generator tends to stabilize at approximately 7.8.
This is within national standards. If the pool pH rises above 7.8, have a pool
professional test to see if other factors such as high Calcium Hardness or Total
Alkalinity are the cause, and then balance accordingly.
5.2.6 Total Dissolved Solids (TDS). Adding salt to pool water will raise the TDS level.
While this does not adversely affect the pool water chemistry or clarity, the pool
water professional testing for TDS must be made aware that salt has been added
for a chlorinator system. The individual performing the TDS test will then subtract
the salinity level to arrive at the correct TDS level.

5.3 Water Chemistry Helpful Hints
5.3.1 Proper operation of the chlorine generator can be easily verified by inspecting the
Electrolytic Cell. The chlorine being produced will appear as a fog at one end of
the plates. However, if the pool remains cloudy, or the chlorine residual tests low,
then the chlorine being produced is being lost due to high chlorine demand or
improper water conditions.
5.3.2 To reduce the chlorine demand, check the pH and Stabilizer (Cyanuric Acid)
reading. If tests show correct, then a shock treatment with an oxidizer agent is
advised. Generally, superchlorination is not necessary if the pool is maintained at
correct levels.
5.4 Recommended List
5.4.1 Read and keep your manual in a safe place.
5.4.2 Increase chlorine production when temperature goes up.
5.4.3 Increase chlorine production when number of guests go up.
5.4.4 Use Stabilizer (Cyanuric Acid) to protect free chlorine in pool
5.4.5 Mount Control Module in shade or out of the direct sunlight whenever possible.
5.4.6 Decrease chlorine production when temperature goes down.
5.4.7 Take pool water sample to a Pool Professional once per month.
5.5 Not Recommended List
5.5.1 Do not allow fertilizer anywhere near your pool. Fertilizers contain Nitrates or
Phosphates which cause severe chlorine demand in pool water.
5.5.2 Never use dry acid to adjust pH. A build up of by-products can damage the
Electrolytic Cell.
5.5.3 Do not add any pool water balancing chemicals (including salt) unless the Power
Unit is turned off.
5.5.4 Do not add any chemicals (including salt) to the skimmers.
5.5.5 Do not let salinity level drop below 3000 ppm.
5.6 Definitions
5.6.1 Algae. Plant-like organisms which grow in water. Especially active in summer
conditions, where chlorine disinfectant level is too low to destroy them. Algae may
be green, yellow, brown or black (Black Spot) in color.
5.6.2 Chlorine Demand. The amount of chlorine that should be added to the water to
provide proper bacteria and algae control.

Compu Pool CPSC Series Manual 7
5.6.3 Chlorine Residual. The amount of chlorine left over, after the “demand” has been
met.
5.6.4 Combined Chlorine. Weak chlorine which is combined with the contaminants in
the water.
5.6.5 Free Chlorine. Active chlorine in the water with the potency to destroy
contaminants.
5.6.6 Shock Treatment. The removal by means of oxidation of those materials that have
chlorine demand.
5.6.7 Superchlorination. An extra large amount of chlorine added to the water.
6.0 ADDING SALT TO POOL OR SPA
6.1 Adding Salt
6.1.1 DO NOT add pool/spa chemicals directly to the skimmer. This may damage the
cell. Maintaining high salt levels above the recommended range can contribute to
corrosion of pool/spa equipment. If the chlorinator has already been installed, it
must be turned off before adding salt. The recommended salt concentration for the
CPSC Series is 3500 ppm.
6.1.2 For pools it is best to empty the required salt into the shallow end of the pool and
run the filter and pump simultaneously while the CPSC Series chlorinator is off or in
manual mode to circulate the water and dissolve the salt. Do not throw the salt bag
into the pool or spa as chemicals and inks on the bag can interfere with the water
balance.
6.1.3 Salt may take 24 –48 hours to dissolve in the summer and longer in the winter.
Finer granules of salt will dissolve faster than compressed pellets.
6.2 Type of Salt to Use
6.2.1 The purer the salt the better the life and performance of the electrolytic cell. Use a
salt that is at least 99.8% pure NaCl. The preferred salt is an evaporated,
granulated, food quality, non-iodized salt. Consult your local pool store.
6.2.2 Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS
or yellow prussiate of soda) that could cause some discoloration of fittings and
surface finishes in pool.
6.2.3 Water conditioning salt pellets are compressed forms of evaporated salt and may
be used but will take longer to dissolve.
6.2.4 Do not use calcium chloride as a source of salt (use sodium chloride only).

Compu Pool CPSC Series Manual 8
6.2.5 Do not use Rock salt. Insoluble impurities mixed with the rock salt can shorten the
life of the unit.
6.3 Salt Level
6.3.1 The Compu Pool CPSC Series chlorinator can work with a broad salinity range,
from a minimum of 3000 ppm (parts per million), up to 6000 ppm. However, the
ideal level for operation is 3500 ppm. To achieve this level of salinity, add 30 lbs. of
salt for every 1000 gallons of water. If you are unsure of the number of gallons in
your pool, double-check with the equations below.
Gallons (Measurements in Feet)
Rectangular
Length x Width x Average Depth x 7.5
Round
Diameter x Diameter x Average Depth x 5.9
Oval
Length x Width x Average Depth x 6.7
6.3.2 The ideal salt level is 3500 ppm. If the salt level is low, determine the number of
gallons in the pool and add salt according to the chart below. A low salt level will
reduce efficiency of the chlorinator and result in low chlorine production. A high salt
level can cause a salty taste to your pool. In addition, operating the unit outside the
recommended salt range will rapidly reduce the longevity of the cell. The salt in
your pool/spa is constantly recycled and the loss of salt throughout the swimming
season should be small. This loss is due primarily to the addition of extra water to
replace water lost from splashing, backwashing, and draining (because of rain).
Salt is not lost due to evaporation.
6.3.3 If salt content is too high you will need to reduce the level of water in your pool/spa
and refill the pool/spa with fresh water that has not been diluted with salt.
6.3.4 To initially start a pool with the correct amount of salt, add salt to the pool at a rate
of 0.03 pounds of salt for every 1 gallon of water.

7.0 INSTALLATION
7.1 Overview
7.1.1 The Power Unit is to be mounted at least 3 feet above ground level, and if possible
protected from direct weather. The Electrolytic Cell is to be plumbed in the return
line to the pool after the pump and filter (and heater, if applicable). Water flow
through the cell can be in either direction, however ideal installation is horizontal,
with the inlet and the outlet pointing down. The three cell lead connectors from the
Power Unit are to be connected to the head of the cell.

7.2 Wiring
7.2.1 Power must be shut off at the circuit breaker before performing any wiring. Be sure
to follow local and NEC electrical codes. The Compu Pool CPSC Series chlorinator
has been designed to easily wire into typical in-ground pool systems. To provide
safe operation, the unit must be properly grounded.
7.2.2 The Power Unit comes with a terminated power cord which is typically connected to
an external timer, which will turn the pump and Power Unit on and off together. As
all individual wiring set ups are unique, have the Power Unit wired to the load side
of the external timer by a qualified person.
7.2.3 In Canada and in some parts of the United States, the Power Unit must be
connected to a circuit protected by a Class A ground fault interrupter (GFI). Check
local codes before connecting.
7.2.4 The Compu Pool CPSC Series is shipped from the factory with a 240 VAC
configuration.
7.3 Changing the Wiring to 120 VAC
7.3.1 Power must be shut off at the circuit breaker.
7.3.2 Remove the six screws from the rear of the Power Unit.
7.3.3 Lift the housing cover off the backing plate.
7.3.4 Refer to Figure 1 for the 120 VAC configuration, moving only the wire on J12 to J11
and the wire on J8 to J14.
7.3.5 Ensure that the gray ribbon cable is secure at both ends.
7.3.6 Replace the housing cover. All wires must be enclosed within the housing so that
they are not pinched between the housing cover and the backing plate.
7.3.7 Replace the six screws in the base of the Power Unit.
