The pump can be operated manually at any time by pushing the switch until
the lamp indicates red. During manual operation the pump will run up to 3
hours with the heater turning on and off under thermostat control. Repressing
the switch restarts the 3 hour timer. At the completion of the manual running
time the controller will revert to automatic mode.
Standby mode switches the pump functions off if absolute quiet is required.
This function is also on a timer reverting to automatic mode after 3 hours.
PUMP FUNCTION SWITCH
When the pump switch is depressed it toggles between auto, manual and
standby modes. The default start up mode is automatic so that in event of a
power failure, the pool always starts in the heating mode.
When in the automatic mode, the indicator shows yellow/orange (Fig 3). The
time clock will automatically turn the system on and off at preset times (see
time clock setting instructions - page 6).
During the on periods as set by the clock and while in automatic mode the
pump and heater are controlled by the thermostat setting, commonly referred
to as a demand heat system. The controller will switch the pump and heating
on and off as well as the intelligent filtration cycling when required.

SPA WATER TREATMENT
RECOMMENDED CHEMICAL VALUES
CHLORINE........... 1.5 - 3.0 PPM ( PARTS PER MILLION )
pH................. 7.4 - 7.6
TOTAL ALKALINITY... 100 - 120 PPM
FAILURE TO MAINTAIN YOUR SPA WATER CHEMISTRY TO
THE ABOVE VALUES CAN BE UNHEALTHY BOTH TO YOU
AS BATHERS, AND TO 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.
