Davey SP601 Series SPAPOWER CONTROLLERS - Manual (Page 3)

6 Auto Sanitising (Filtration)
6.1 No 24hr Circulation Pump Fitted
The Spa Power controller automatically maintains the filtration/sanitising of the spa pool water. The
minimum amount of filtration time is programmable by the user and can be adjusted between 0 and
15 minutes per hour (0 to 6 hours per day). In order to maintain correct filtration of the pool water, the
controller 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 the pump for an additional period every hour to reach the
minimum filtration time set by the user.
6.1.1 Adjusting Minimum Filtration Time (No 24hr circulation pump fitted)
First push the Down andAir/Aux buttons together to display the filtration time setting on the digital readout
6.1.2 Clean Up Cycle
If desired, a clean up cycle can be initiated to filter the water after the spa pool has been used.This is
done by simply pushing the Pump Button
to leave auto mode and switch on the pump. This will
circulate the water through the filter for 90 minutes.After 90 minutes the system will return to auto mode
and maintain the temperature ready for the next time the spa pool is used.
6.2 24hr Circulation Pump Fitted
The Spa Power controller continuously filters the spa pool to ensure the water is clean and crystal clear
for each and every spa use. A near silent energy efficient circulation pump constantly passes water
through the filter and since the circulation pump runs all the time (except for when the time clock has
been set to sleep or in an error condition) and the heater is controlled automatically there is no need for
any user controls for these features. With a 24hr circulation pump fitted there is no need to program any
filtration cycles,and the noise of a large jet pump running during filtration has bee nremoved.
6.3 My Spa Is Too Hot In Summer!
During warm periods of the year there may be times when the actual water temperature exceeds
the desired temperature set by the user. E.g. If the spa is set to heat to 35
o C , but the actual water
temperature is hotter than 35 o C. Please consider this - In the winter your spa gets cold because the air
temperature is cold. To combat this we heat the water and keep the spa covered when not in use. If the
spa is turned off and the ambient temperature is 15
o C, eventually the spa water will lose heat until it too
is 15 o C. In the summer the same applies but in reverse - you can turn the heater down, even turn the
pump off, but if the ambient daytime temperature is 35 o C - 42 o C then the spa water will also remain at
that temperature. Manufacturers make no attempt to supply a system that cools water. The quickest
way to combat the problem is to change the water, but even this new water will eventually heat up to the
air temperature.Turn the set temperature down so the heater does not come on. Reduce the minimum
filtration time (non circ pump models only) so the pump runs less.The less the pump runs the more the
water will cool. If the night time temperature is low, leave the cover off the spa to let heat escape, but
put it back on during the day to keep heat out. If the optional time clock is fitted increase the sleep time
period otherwise turn the spa off overnight. Also make sure the spa is shaded from direct sunlight.
The default setting is 10 minutes per hour (= 4 hours per day). Holding down the Up Button or Down
Button will adjust the filtration time setting between 0 and 15 minutes per hour. (= 0 to 6 hrs per day).

Installation & Safety Notes (cont’d)
11. The floor or base on which the pool is installed has to be capable of supporting the expected load.
12. Precautions should be taken to ensure that spa pool water is disposed of appropriately.
13. An adequate drainage system should be provided to deal with overflow water.
14. Precautions should be taken to avoid damage due to water freezing in the pipes and fittings.
15. Precautions should be taken to avoid damage when the pool is left empty for an extended period.
Spa Water Treatment
Recommended Chemical Values
Chlorine.........................1.5-3.0PPM(Parts Per Million)
pH..................................7.2-7.6
Total alkalinity................80-120PPM
It 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 (below7.0 is acid, above7.0 isalkaline).Low
pH will cause corrosion of any metalwork in the water (element, thermostat pockets). High pH will
cause scale formation and cloudywater.
Total Alkalinity
This is ameasure of how resistant your spa water is to change of pH. A low TA (0-80ppm)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.
Chlorineis 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.
