Problem C: Chlorine odour
CAUSE: Not enough free chlorine.
Surprisingly, the problem here is not too much chlorine as many imagine. Chloramines form by
the bonding of chlorine with amines from sweat and other sources. These chloramines can
create a chlorine odour and can also cause eye and skin irritation. Free chlorine does not smell
(up to 10 ppm concentration).
REMEDY:
Manually shock the pool following the directions in Problem B.
Problem D: Slimy pool walls
CAUSE: Combined algae and bacteria growth.
REMEDY:
Brush down the affected walls and follow remedy for Problem B, manually shocking pool with
sodium hypochlorite (liquid chlorine).
Problem E: Eye and/or skin irritation
CAUSE: Improper water balance.
REMEDY:
Balance the water (See ‘Tips on Water Chemistry’).
Problem F: Scale formation on pool equipment
To clean the deposit (scale) from the cell, see
Maintenance
section.
CAUSE 1: Incorrect pH causing metals to come out of solution.
REMEDY:
Adjust alkalinity to 100-120 ppm. Then adjust the pH to within the range 7.2 – 7.8 (See ‘Tips on
Water Chemistry’).
CAUSE 2: High total hardness.
REMEDY:
Dilute pool with fresh water. Consult your pool professional regarding use of a sequestering
agent.
Problem G: Chlorine output indicator will not illuminate, ‘Check Salt’ indicator on
CAUSE 1: Low incoming voltage.
REMEDY:
Confirm proper wiring with an electrician. This unit is factory set at 110 volts. If incoming voltage
is low due to location (rural areas for example), raising the salt level will compensate. Do not
exceed 5000 ppm of salt as it may contribute to corrosion of the other pool equipment.
CAUSE 2: Salt level too low.
REMEDY:
30
