IMPORTANT SAFETY INSTRUCTIONS
When using electrical equipment, basic safety precautions should
always be exercised, including the following:
Cautions:
Please note, the total working hours for the T-Cell should be less than
8 hours total per day. If you are using a variable speed pump for 24
hours a day be sure to adjust the chlorine output to 25-30%. If the
pump is only running 10 hours per day adjust the chlorine output
between 60-80%.
You can use this calculation to calculate the appropriate chlorine
output for your pool, suggest at 6 hours per day.
Pump running 24(Hours a day) *25% (Chlorine Output) =6hr (cell run time per day at 25%).
Pump running 20(Hours a day) *30% (Chlorine Output) =6hr (cell run time per day at 30%).
Pump running 15(Hours a day) *40% (Chlorine Output) =6hr (cell run time per day at 40%).
Pump running 12(Hours a day) *50% (Chlorine Output) =6hr (cell run time per day at 50%).
Pump running 8(Hours a day) *75% (Chlorine Output) =6hr (cell run time per day at 75%).
Start the VS pump on a low speed and kick the speed up until the salt
system works.

READ AND FOLLOW ALL INSTRUCTIONS
⚫Disconnect all AC power during installation.
⚫Do not permit children to use this product.
⚫A green-colored screw is located inside the wiring compartment,
against the back panel. To reduce the risk of electric shock, this
terminal must be connected grounded by connecting a continuous
copper wire, equivalent in size to the circuit conductors supplying
the equipment. Use the means provided in the electric supply
service panel to connect the terminal to the grounding.
⚫Includes one bonding lug for US models (two for Canadian models)
located on the external surface. To reduce the risk of electric
shock, connect the local common bonding grid in the area of the
swimming pool, spa, or hot tub to these terminals with an insulated
or bare copper conductor not smaller than 8 AWG US/6 AWG
Canada.
⚫All field-installed metal components such as rails, ladders, drains,
or other similar hardware located within 10 feet (3 meters) of the
pool, spa or hot tub shall be bonded to the equipment grounding
bus with copper conductors not smaller than 8 AWG US/ 6 AWG
Canada.

OPERATION
The BLH is an automatic chlorine generation system for pool & spa sanitation. The operation
requires a low concentration of salt (sodium chloride) in the pool water at levels low enough
that it normally cannot be tasted. The BLH automatically sanitizes your pool by converting
the salt into free chlorine, which kills bacteria and algae in the pool through a process called
electrolysis.
The BLH is designed to handle the purification needs of the average residential swimming
pool up to 40,000 gallons (150,000 liters). The actual amount of chlorination required to
properly sanitize a pool varies depending upon the bather load, rainfall, air temperature,
water temperature, pool’s exposure to sunlight, pool’s surface, and cleanliness.
Note: It is not recommended using the BLH to generate Bromine.
If your pool has natural stone as coping or decking, please check with a stone installation
specialist for the maintenance of the stone before installing the BLH.
WATER CHEMISTRY
As with any pool, you must maintain proper water chemistry of the pool water. Proper water
chemistry will include pH, alkaline content, and calcium levels. The only special requirement
for the BLH is to maintain proper levels of salt and stabilizer. It is important to maintain these
levels to prevent corrosion or scaling and to ensure maximum enjoyment of the pool, by
testing your water periodically. It is recommended that pool water is professionally tested a
minimum of twice per season. Your local pool store can provide you with the chemicals and
procedures to adjust the water chemistry. Be sure to tell the pool store that you are using a
salt-chlorine generator.

Saturation index
The saturation index (Si) relates to the calcium and alkalinity in the water
and is an indicator of the pool water "balance". Your water is properly
balanced if the Si is 0 ±.2. If the Si is below -0.2, the water is corrosive
and plaster pool walls will be dissolved into the water. If the Si is above
+0.2, scaling and staining will occur. Use the chart below to determine
the saturation index.

How to use: Measure pool pH, temperature, calcium hardness, and total
alkalinity. Use the chart above to determine Ti, Ci, and Ai from your
measurements. Insert values of pH, Ti, Ci, and Ai into the above
equation. If Si equals .2 or more, scaling and staining may occur. If Si
equals -.2 or less corrosion or irritation may occur.

SALT LEVEL
Use the chart below to determine the amount of salt needs to be added to reach the
recommended levels. Use the equations below to determine the size of your pool.
•The ideal salt level is between 3000-4000 ppm. (parts per million) with 3400 ppm
being the optimal level. Calculate the number of gallons in the pool and add salt
according to the chart on page10.
•A LOW salt level will reduce the efficiency and result in low chlorine production,

making the pool water unsafe for swimmers.
•Excessively HIGH salt levels will cause the BLH to shut down, making pool water
unsafe for swimmers.
Type of Salt to Use
It is important to use only sodium chloride (NaCl) that is 99% pure. This is a common food
seasoning or water softener salt available in 40-80-pound bags, at your local store. It is also
acceptable to use water conditioning salt pellets; however, it will take longer for them to
dissolve. Do not use rock salt in your pool water. It is recommended to use salt with more
than 1% of yellow prussiate of soda (sodium ferrocyanide), salt with more than 1% of anti-
caking additives, or iodized salt.
How to Add or Remove Salt
•IN GROUND POOLS: Turn the filter pump on and add the salt directly into the pool
at the shallow end.
•ABOVE GROUND POOLS WITH MAIN DRAINS: Add directly in front of the return
jet to pool. Run the filter pump for 24 hours with the suction coming from the main
drain (use the pool vacuum if there is no main drain) to allow the salt to evenly
disperse throughout the pool.
•ABOVE GROUND POOLS WITHOUT MAIN DRAINS: Add directly into the pool.
Brush the salt to speed up the dissolving process—to not allow the salt to sit in a
pile on the bottom of the pool. -------ELIMINATE THE FOLLOWING--(Run the filter
pump for 24 hours with the suction coming from the main drain (use the pool
vacuum if there is no main drain) to allow the salt to evenly disperse throughout
the pool).
DO NOT ADD SALT DIRECTLY TO THE SKIMMERS OR DIRECTLY INTO THE MAIN
DRAIN, ON ANY Pool. THIS WILL SHUT DOWN OR SHORTEN THE LIFE OF THE CELL
DUE TO HIGH SALT CONCENTRATION AND REDUCED FLOW TO THE PUMP.
If added incorrectly, immediately turn off the BLH for 24 hours with the pump and filter still

operating. This will help to evenly distribute the salt. The salt display may up to 24 hours to
respond to the change in salt concentration.
SALT DOES NOT EVAPORATE FROM POOL
The only way to lower the salt concentration is to partially drain the pool and refill with fresh
water.
