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.
