5.0 THE CHEMISTRY INVOLVED
5.1.1 The C-CPP Commercial Series Chlorine Generator by electrolysis creates chlorine
to sanitize the pool using the salt molecules (NaCL) in the water. A small electric
charge is applied across a set of titanium plates inside the Electrolytic Cell(s). This
produces Sodium Hypochlorite (NaOCl). In water, Sodium Hypochlorite dissociates
into sodium (NA+) and hypochlorite (OCl-) ions.
5.1.2 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.
6.0 WATER CHEMISTRY
6.1 WARNING: Prior to turning on the C-CPP Series Chlorine
Generator for the first time (including reopening the pool for the
new pool season) the water chemistry must be balanced
according to the following guidelines.
6.1.1 With proper filtration and chemically balanced water the pool should be clear and
sparkling. Unbalanced water can result in scaling, corrosion of pump equipment
and inefficient operation of the C-CPP system.

6.2.1 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.

Compu Pool C-CPP Commercial Series Manual 7
6.2.2 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.
6.2.3 Nitrates and Phosphates. These chemicals can cause extremely high chlorine
demands and will deplete chlorine from the pool. In some cases, they may even
lower the chlorine levels to zero. A pool professional can test for Nitrates and
Phosphates.
6.2.4 Metals. Metals can cause loss of chlorine. Also, metals can stain the pool and tint
the water. A pool professional can check for metals and recommend methods of
removal.
6.2.5 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 the pool, and does not allow the chlorine in the 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.
6.2.6 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.
6.3 Water Chemistry Helpful Hints
6.3.1 Proper operation of the chlorine generator can be easily verified by inspecting the
Electrolytic Cell. The chlorine being produced will appear as a fog along 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.
6.3.2 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.
6.4 Recommended List
6.4.1 Read and keep the manual in a safe place.
6.4.2 Increase chlorine production when temperature goes up.
6.4.3 Increase chlorine production when number of pool users goes up.
6.4.4 Use Stabilizer (Cyanuric Acid) to protect free chlorine in the pool.
6.4.5 Decrease chlorine production when temperature goes down.

Compu Pool C-CPP Commercial Series Manual 8
6.5 Not Recommended List
6.5.1 Do not allow fertilizer anywhere near the pool. Fertilizers contain Nitrates or
Phosphates which cause severe chlorine demand in pool water.
6.5.2 Never use dry acid to adjust pH. A build up of by-products can damage the
Electrolytic Cell.
6.5.3 Do not add any pool water balancing chemicals (including salt) unless the
Chlorinator is turned off.
6.5.4 Do not add any chemicals (including salt) to the skimmers (if applicable).
6.5.5 Do not let salinity level drop below 3500 ppm.
6.6 Definitions
6.6.1 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.
6.6.2 Chlorine Demand. The amount of chlorine that should be added to the water to
provide proper bacteria and algae control.
6.6.3 Chlorine Residual. The amount of chlorine left over, after the “demand” has been
met.
6.6.4 Combined Chlorine. Weak chlorine which is combined with the contaminants in
the water.
6.6.5 Free Chlorine. Active chlorine in the water with the potency to destroy
contaminants.
6.6.6 Shock Treatment. The removal by means of oxidation of those materials that have
chlorine demand.

Compu Pool C-CPP Commercial Series Manual 9
7.0 ADDING SALT TO POOL OR SPA
7.1 Adding Salt
7.1.1 DO NOT add pool/spa chemicals directly to the skimmers (if applicable). 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 C-CPP Series is 3500 ppm.
7.1.2 It is best to empty the required salt around the perimeter of the pool and run the
filtration simultaneously while the C-CPP Series chlorinator is off to circulate the
water and dissolve the salt. Do not throw salt bags into the pool or spa as
chemicals and inks on the bag can interfere with the water balance.
7.1.3 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.
7.2 Type of Salt to Use
7.2.1 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.
7.2.2 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.
7.2.3 Water conditioning salt pellets are compressed forms of evaporated salt and may
be used but will take longer to dissolve.
7.2.4 Do not use calcium chloride as a source of salt (use sodium chloride only).
7.2.5 Do not use Rock salt. Insoluble impurities mixed with the rock salt can shorten the
life of the unit.
7.3 Salt Level
7.3.1 The Compu Pool C-CPP 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
the pool, double-check with the equations below.
Pool Shape
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

Compu Pool C-CPP Commercial Series Manual 10
7.3.2 The ideal salt level is 3500 ppm. 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 the pool. In addition, operating the unit outside the recommended salt
range will rapidly reduce the longevity of the cell. The salt in the 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.
7.3.3 If salt content is too high you will need to reduce the level of water in the pool/spa
and refill the pool/spa with fresh water that has not been diluted with salt.
7.3.4 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.
8.0 INSTALLATION
8.1 Positioning
8.1.1 The C-CPP series chlorinator must be installed in a room or area that is protected
from the environment and weather. The chlorinator must not be installed into a
location that is used for chemical storage as this will void the warranty.
8.1.2 Water leaks, no matter how small should be attended to immediately. If there is
water in the vicinity of the chlorinator, condensation may form on the internal
electrical components which can result in malfunction. The warranty will not cover
malfunction due to condensation or weather.
8.1.3 The chlorinator must be positioned downstream from the filtration plant and
upstream from any heating equipment.
8.1.4 Positioning should allow for easy access to the electronics module door, control
panel, cell bays and valves.
8.1.5 The chlorinator can be moved into position with either a forklift or pallet jack(s).
8.2 Plumbing
8.2.1 The C-CPP series chlorinator must be plumbed to the main return pipe of the pool
after the filtration system.
8.2.2 A branch line needs to be taken from the main filtration return line and diverted
through the Chlorinator to create a bypass installation. This must be done in the
manner shown in the plumbing diagram in the following section (Figure 1). Installing
the Chlorinator in this manner avoids excessive pressure on the Chlorinator and
filtration system. Additionally the Chlorinator can be isolated from the main flow
return line to enable uninterrupted filtration.

Compu Pool C-CPP Commercial Series Manual 11
8.2.3 The bypass installation must be made from 3" (80mm) PVC pipe. The M1 and M2
valves supplied with the Chlorinator are for this size pipe.
8.2.4 The flow sensor must be installed before the Chlorinator as shown in the plumbing
diagram (Figure 1). Chlorine production will only occur when the flow sensor
detects sufficient water flow, thus protecting the electrolytic cells.
8.2.5 The M1 Valve (inlet) and M2 Valve (outlet) are used to allow the flow of water
through the Chlorinator. These valves are closed when the acid wash cycle is
running.
8.2.6 The M3 Valve can be used to direct a portion of the main line flow though the
Chlorinator line. In most installation scenarios this valve can be left fully open.
8.2.7 The M4 Valve and M5 Valves are installed to facilitate quick isolation of the
Chlorinator from the filtration line. When the Chlorinator is not in use the valves can
be closed. Additionally if the Chlorinator needs to be moved for any reason,
disconnecting these valves will enable this.
8.2.8 The AW1, AW2 and AW3 Valves are used for the acid wash cycle. During normal
operation of the Chlorinator, these are all closed. The acid wash system requires a
waste line in 3/4" (20mm) PVC pipe. This line will be used to waste the diluted acid
cleaning solution. Please note that most country / state regulations require
hydrochloric acid to be neutralised and dumped in an environmentally sound
manner.
8.2.9 Once the plumbing is completed the bypass line valves should be slowly opened to
check for proper hydraulic sealing.
8.2.10 The C-CPP Series Chlorinator has been designed to operate with a maximum
working pressure of 40Psi (275kPa). Damage to the electrolytic cells may occur if
the working pressure exceeds this limit.
8.2.11 The M1 and M2 Valves are neatly contained within the sheetmetal construction. To
complete the plumbing of the M1 and M2 Valves, carry out the following procedure.

Compu Pool C-CPP Commercial Series Manual 12
01. Remove the two plumbing end
sheetmetal cover panels by unscrewing
the 18 M5 cap head screws with the 4mm
hex key provided.
02. Remove the two sheetmetal valve
covers by unscrewing the 8 M4 nuts with
a 7mm (9/32") socket.
03. Unscrew the outside collars of the 3"
(80mm) ball valves. Place the sheetmetal
valve covers over the 3" plubing lines.
04. Using high pressure PVC solvent
cement glue the valve union to the 3"

11.2 Electrolytic Cell
11.2.1 The cell operates most efficiently when it is clean. As a natural result of the
electrolytic process which creates chlorine from salt molecules, calcium build up is
attracted to the titanium plates in the cell. The cell requires regular cleaning to
ensure that build up does not cause individual plates to come in contact with each
other. The clear housing of the cell(s) allows easy visual inspections, however as a
general rule the cell should be cleaned every 4 weeks.
11.3 Acid Wash
11.3.1 Note: This procedure must be carried out with care in a well ventilated area. Read
and observe the relevant Material Safely Data Sheet (MSDS) and always wear
Hydrochloric Acid resistant protective clothing. Observe all relevant occupational
health and safety procedures.
11.3.2 Before beginning the Acid Wash ensure that the M1, M2, M4 and AW2 valves are
closed and the AW1 and AW3 valves are open (refer to Figure 1 - Plumbing
Diagram). Chlorine production will cease when the M4 valve is closed as the flow
switch will detect no water flow.
11.3.3 The acid wash system requires the electrolytic cells to be filled with water to assist
in diluting the acid added to the acid tank. Do not attempt to drain the water from
any of the cells.
11.3.4 Using the acid tank fill can provided, add water up to the "Water Fill Line" (10.5
Litres, 2.8 Gallons). Then add hydrochloric acid to the "Acid Fill Line" (4.5 Litres,
1.2 gallons). Always add acid to the water, never water to acid.
11.3.5 Unscrew the acid tank fill cap and fill the contents of the fill can into the acid tank.
Be careful not to spill any of the acid solution on the Chlorinator components as this
can result in corrosion of the sheetmetal parts..
11.3.6 Use only concentrated Hydrochloric Acid (30-35% concentration HCl). The mixture
of the tank contents, when combined with the water of each cell will provide a
diluted acid concentration of 5.0%. Under no circumstances should you attempt to
strengthen this mixture as it may result in damage to the Chlorinator.
11.3.7 The function of the acid wash valves are as following:
AW1 - Cell Valve (line from acid tank to cell housings).
AW2 - Waste Valve (line from cell housings to waste).
AW3 - Acid Tank Return (line from cell housings to acid tank).
11.3.8 Ensure the AW1 and AW3 valves are open and that the AW2 valve is closed. Turn
the acid pump on at the control panel.
11.3.9 Run the acid wash for 20-30 minutes. Do not run the acid wash for longer than 30
minutes as this may damage the Chlorinator.

Compu Pool C-CPP Commercial Series Manual 20
11.3.10 During the acid wash cycle there can be no air in the electrolytic cells. If there is air
in the cell housings carefully remove the Air Bleed bolts from the top of the cell
head by hand. Once the air is removed carefully and quickly screw the bolts back in
simultaneously. Note: The air bleed bolts can only be hand tightened. Do not
tighten with tools as this will damage the cell head.
11.3.11 When the acid wash cycle is completed close the AW3 valve and open the AW2
valve, this will pump the acid solution in the acid tank to the waste line. When the
acid tank is empty turn off the acid pump at the control panel. Warning: Do not run
the acid pump dry as this will damage the pump.
11.4 Replacing the Cell
11.4.1 When the titanium blades inside the Electrolytic Cell have reached the end of their
lifespan, replacements are available so that the whole system does not have to be
removed. Replacements are easily switched out. To ensure quality and value, only
genuine Compu Pool replacement parts may be used.
11.5 Removing the Cell for Replacement
11.5.1 Disconnect the nuts clamping the cell leads to the cell heads with the appropriate
sized socket.
11.5.2 Turn valves M1 and M2 to the closed position.
11.5.3 Unscrew the air bleed bolts at the top of the cell heads.
11.5.4 Turn the AW2 valve to open to let a small amount of water out of the cell housings.
11.5.5 Unscrew the cell head collar.
11.5.6 With a large flat bladed screwdriver carefully leverage the cell out of the housing
enough so that it can be lifted out by hand. Carefully remove the cell.
11.5.7 Insert the new cell in the reverse manner. Ensure that the cell head collar is
screwed down tightly and that the nuts clamping the cell leads to the cell head are
tight.
