3. SPA/POOL BALANCE:
It is very important to keep your water balanced. Balanced water will feel better, look better and be
healthier.
MAINTENANCE OF CHEMICAL LEVELS - pH
A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water,
etc. Correct levels are as follows; Fibreglass - 7.0 to 7.4. Other pools and spas - 7.2 to 7.6. Chemicals
to raise or lower pH are available from your pool/spa dealer.
TOTAL ALKALINITY
Total alkalinity should not be confused with pH, although the two are closely related.
Total alkalinity determines the speed and ease of pH change. It is measured in ppm - the ideal range
is 80-150ppm, or refer to your pool builder.
You should use a test kit which includes a test for Total Alkalinity.
Low Total Alkalinity can cause unstable pH levels - i.e. an inability to keep the pH constant may
cause staining, etching and corrosion of metals. High Total Alkalinity will cause constantly high pH
levels.
Consult your local Ozomatic
®
dealer for more information.
CHLORINE/BROMINE
Ozone is used as a primary oxidiser and will take care of contaminants introduced into the water
whilst the unit is operating. When the unit turns off, the ozone level will drop rapidly. It is suggested
that a residual dose of chlorine/bromine be introduced into the spa/pool to take care of contaminants
that may enter between filtration cycles. In above ground pools a floating dispenser with slow dis-
solving tablets would complement the Ozomatic. The addition of chlorine or bromine is recom-
mended for spas. On below ground pools salt water chlorination is a better alternative because of the
residual factor and can be used in conjunction with an Ozomatic. In 24 hour circulation systems
chemical additions will be minimised.
This information is provided as a guide to help you on the way to understanding your Ozomatic and
how to obtain the best from your water. Your local Ozomatic dealer can advise you in detail.
4. TROUBLE SHOOTING:
Water keeps going cloudy
1. Check that blue light is on.
2. Check that fine bubbles are present in spa.
3. Check that running time is adequate.
4. Check water balance.
5. Check you have an appropriate chlorine/bromine residual.
If the blue light is on then the unit is working. You can confirm this by smelling for ozone near the
water surface. Check items 3, 4 and 5. If the blue light is not on then check that there is power to the
unit by plugging a lamp or similar appliance into the power outlet normally used for the Ozomatic. If
the appliance works then the Ozomatic requires service. Return the unit to your nearest Davey
authorised service agent. Do not attempt to open the bulb chamber because the UV light will damage
your eyes, also never breathe in concentrated ozone.
