10. Always take water samples from a point near the skimmer box, for this is
where the water is completely mixed, giving the most accurate readings.
Never take water samples near the pool returns (“eye-balls”) where the
Chemigem may have freshly dosed the pool water.
11. It is very important that the reagents in the test kit are well within their use-
by date, otherwise false readings may result. If in doubt, take a water sample
to a pool shop for testing.
12. Chemicals must be carefully diluted according to the size of the pool or spa.
Always add the concentrated chemical to the water and never add the water
to the concentrated chemical. Some chemicals react violently with water and
can splash into face and eyes.
13. Always wear protective face-shield and gloves for such operations. Fully
observe all the chemical manufacturer’s safety instructions when handling
pool chemicals.
14. Ensure the chemical supplies (liquid Chlorine and pool Acid) are kept in
visually different containers to avoid wrong connection. Use colour or size
differences or both. When these two concentrated chemicals are mixed
together out of the pool water, poisonous gas is produced.
15. A qualified electrician must affix the electrical outlet (housing the power to
the pool) and, if required, to hard-wire the unit to the power source.
16. If it is decided to turn off the Chemigem audible alarm for any reason, the
unit will no longer have that warning capability and the pool owner will have
to rely on their own ability to monitor the indicator lights on the face of the
unit to verify that the Chlorine and pH levels are within acceptable limits.
IMPORTANT SAFETY MEASURES:
•
Always add concentrated chemicals to water
– not the other way around!
•
Don’t allow chemicals to mix – dangerous, highly corrosive fumes will be
produced.
•
Always wear protective clothing, footwear, gloves and eye protection when
handling pool chemicals to avoid injury.
•
If a spill occurs, wash the affected area with fresh water immediately and seek
medical attention.
•
Work in a well-ventilated area and avoid inhalation of fumes.
•
Read and follow safety instructions on chemical drums.
