GENERAL PRECAUTIONS
• Do not use bromine based products in the pool. Use of bromine will void the
warranty on your chlorine cell.
• It is the pool owner's responsibility to ensure water is regularly tested and balanced.
Your local pool professional can advise you on appropriate testing frequency and
balance criteria in your area.
• When taking a water sample for testing, make sure to use an appropriate water
sample bottle (available from most pool shops), and ensure the sample is as fresh
as possible. Avoid exposing the sample to heat and/or sunlight while in transit.
• Do not use old soft drink bottle for water samples as this may produce highly
inaccurate test results.
• Where calcium hardness of the pool / spa water exceeds 200ppm, the water must
be balanced according to the Langlier Index to ensure water is not scale forming.
Consult you local pool professional for advice.
• Do not assume the chlorinator is faulty if a chlorine test reveals a low free chlorine
level. There are many factors that relate to chlorine demand in the water. Refer to
the troubleshooting guide in this manual for more information
• Regular manual 'super chlorination' or 'shock dosing' may be required in pools
particularly where chlorine demand or bather load is high.
• Test salt level before calculating your salt addition requirements, even on a new
installation – especially where liquid chlorine had been used previously.
• Free chlorine levels above 4.0ppm may void manufacturer warranties on your
equipment.
• Unnecessarily high salt levels may contribute to corrosion of pool and spa
equipment.
• Only use original and proprietary Pool Lab Reagent Bags.
• Never add pool or spa chemicals directly to the skimmer as this can lead to false pH
and chlorine readings on the ASP, and therefore incorrect chemical dosing.
• Pool Lab recommend the use of Cyanuric Acid (Stabilizer) at a concentration
of between 50-80 ppm for outdoor pools to help protect chlorine in the water
from destruction by sun light
