Spa or hot tub water temperature should never exceed40˚C.
Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to
unconsciousness and subsequently result in drowning.
Pregnant women beware! Soaking in water above 38˚C can cause foetal damage during the first three months of
pregnancy.
Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer, spa or hot
tub thermostats may be inaccurate by as much as 2˚C.
Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain

CHEMICAL BALANCE
It is imperative that correct chemical balance be maintained in your pool and spa water, otherwise corrosion of you
r
heater ma
y
occur. Corrosion due to chemically imbalanced water or excessive sanitise
r
is detectable and will void warranty. Your
local pool shop specialist or spa retailer can advise correct chemical balance. Your water should be checked and maintained
regularly by a pool water professional. As a guide the following parameters may be used.
pH
Total Alkalinity
Calcium Hardness
7.6 to 7.8
80 to 120 ppm
150 ppm
You should test your water chemical balance at least on a weekly basis.
Excessive sanitise
r
can damage your heater. Chlorine should not exceed 3 ppm and bromine should not exceed 5 ppm. Salt
chlorinators, especially when used on spa pools or indoor or covered pools, can easily produce excessive chlorine levels which will
damage the heater internals.
WINTER OPERATION
If the pool won’t be used for a month o
r
more, turn the heater off at the main isolating switch. For areas where there is no danger of
freezing, water should circulate through your heater all year long even though you are not heating your pool.
Where freezing is possible, it is necessary to drain the water from the heater. This may be done by loosening the inlet or outlet
barrel union. If the heater is below water level, isolate it from the pool first by closing shut off valves before and after the heater.
CAUTION: If the heater has been drained for freezing conditions, do not turn on until the system is circulating water.
