of the chassis backplate to a common bonding point. Do
not use the power pack as the common bonding point.
Each piece of non-related pool equipment requiring a
ground should also be bonded to the common, approved
bonding point. There should be one bonding connection
to the power pack. In Canada, the Canadian Electrical
Code (CEC) dictates that the bonding conductor be,
minimum 13.3 mm
2
(6 AWG).

Split Return Plumbing Instructions:
For Infl oor Cleaning Systems
If the chlorinator is used with an in-fl oor cleaning
system, it must be installed in a separate dedicated
return line or damage to the chlorinator will occur.
NOTE
Do not install the chlorinator on in-floor systems that do
not have a dedicated pool return as shown in Figure 5.

Preparation
4.1
Determining Pool Size (Litres)
• Rectangular Pools
Length (metres) x width (metres) x average depth
(metres) x 1000 = litres capacity.
• Circular Pools
Radius (metres) x Radius (metres) x 3.14 x average
depth (metres) x 1000 = litres capacity.
• Oval Pools
Short Radius (metres) x long radius (metres) x 3.14
x average depth (metres) x 1000 = litres capacity.
4.2
Determining Pool Size (Gallons)
• Rectangular Pools
Length (feet) x width (feet) x average depth (feet) x
7.5 = gallon capacity.
• Circular Pools
Radius (feet) x radius (feet) x 3.14 x average depth
(feet) x 7.5 = gallon capacity.
• Oval Pools
Long radius (feet) x short radius (feet) x 3.14 x
average depth (feet) x 7.5 = gallon capacity.
4.3 Chemistry You Need to Know
•
Chlorine Stabilizer (cyanuric acid) is needed
to maintain proper levels of chlorine. Most non-
stabilized chlorine is destroyed by the UV radiation
from the sun within two (2) hours. Chlorine
stabilizer should be maintained between 30 - 50
ppm. For indoor pools, it is not necessary to add
chlorine stabilizer to the swimming pool water.
• Nitrates can cause extremely high chlorine demands
and will deplete chlorine from your swimming pool.
In some cases nitrates may even lower your chlorine
levels to zero. Your local pool professional can test
for nitrates. Make sure nitrates are not present in
your pool.
• Metals (some metals) can cause loss of chlorine and
stain your pool. Have your local pool professional
check for metals and recommend methods of
removal.
• Combined Chlorine (Chloramines) should not
be present in pool water. When organic materials
combine with 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 to remove chloramines at the initial
startup of the pool.
• Shocking or Super Chlorination enhances
chlorine’s ability to oxidize organic waste by
eliminating combined chlorine (CC). To measure
combined chlorine (CC), subtract the Free Chlorine
(FC) from the Total Chlorine (TC). (TC - FC = CC).
To determine how much shock (fast dissolving
chlorine) it will take to properly shock your pool,
you’ll need to calculate the Breakpoint Chlorine
(BPC) level. To determine the Breakpoint Chlorine
(BPC) needed, multiply the Combined Chlorine
(CC) level by 10. Then, subtract the Free Chlorine
(FC) level. Here’s the Formula:
Breakpoint Chlorine (BPC) = ((CC X10) - FC)
for example: If FC=1.0ppm, and if CC=0.7ppm, the
BPC level would be 6.0 ppm. formula: ((0.7x10) -
1.0)=6.0
Your local pool professional can help with this
calculation or can supply you with test kits that can
provide this information. Running your unit at 100%
for 24 hours may also help you achieve breakpoint
