AUto SANItISING (fIltRAtIoN)
The Spa Power 500A Mk2 automatically maintains the filtration/sanitation of the spa
pool water. The minimum amount of filtration time is programmable by the user & can be
adjusted between 0 & 15 minutes per hour (0 to 6 hours per day). 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 the pump for an additional period every hour to reach the minimum
filtration time set by the user.
AUxIlIARY AIR BUttoN
The Air button controls an auxiliary air blower (or water pump). It is used to turn the blower
on & off. Two pushes of the air button cycles the blower as follows:
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 & 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 & maintain the temperature ready for the next time the
spa pool is used.
Adjusting minimum filtration time
First push the Down
& Air/Aux buttons together to display the filtration time
setting on the digital readout.
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 & 15 minutes
per hour (= 0 to 6 hrs per day).

Note: If left on, this accessory will automatically switch off after 20 minutes. If the heater element is on,
switching on this accessory may cause the heater to loadshed & switch off. This is to keep the total
power load to a safe level.
