Total alkalinity ................ 100 - 120 PPM
I
t is important to maintain your spa water chemistry to the above values to ensure a
healthy experience both for you as bathers and for your spa pool equipment.
PH
This is a measure of how acid or alkaline the spa water is (below 7.0 is acid, above 7.0 is alkaline).
Low pH will cause corrosion of any metalwork in the water (element, thermostat pockets). High
pH will cause scale formation and cloudy water.
Total Alkalinity
This is a measure of how resistant your spa water is to change of pH. A low TA (0 - 80 ppm) will
allow the pH to fluctuate rapidly normally to the acid end and will make it very hard to correct the
pH back to the ideal range.
Chlorine
Levels of sanitiser are important to prevent the build up of bacteria, and algae in the pool water.
Chlorine is not the only sanitiser available to do this. Other sanitisers are Bromine, Ozone.
Damage to the element, thermostat pockets and associated metalwork due to the poor
maintenance of water chemistry is not covered by warranty.

- Page 2 - Prime Failed This is not necessarily a problem with the SP500A Mk2 itself, but indicates that no water is being detected in the heater housing. Prime failed is a special case in that it can be recovered from by pushing a button. A push of the pump button will run the pump for 10 seconds to try to get water to the heater.
- Page 3 15 C. In the summer the same applies but in The Spa Power 500A Mk2 automatically controls the pump and heater to filter the water and maintain it at the reverse - you can turn the heater down, even turn the pump off, but if the ambient daytime desired temperature as set by the user (see below).The user can leave the system to look after the spa and know it...
- Page 4 In order to maintain correct filtration of the pool water, the SP500A Mk2 monitors the time for which the pump runs in normal pool operation. If the pump has only run for a short time, the system will automatically run Pump the pump for an additional period every hour to reach the minimum filtration time set by the user.
