To protect the pump and the titanium heat exchanger tanks, the system will not allow operation unless
the water flows correctly. If water does not flow smoothly or if there is air trapped in the system for
more than 2 minutes, the safety system will first attempt to fix it by causing the pump to surge a few
times, but if that fails it will direct a shut down for safety.
Water Flow Issues
Intelligent Water Flow
Correction
if the water does not flow steadily when you first start up
due to air being trapped in the hoses to and from the pool
or inside the water pump, your iCool will attempt to clear it
automatically 3 times.
If this is not successful the touch screen will direct you on how
to correct this issue.
The most common issue that can prevent successful
operation is lack of water flow.
It can occur if air is trapped in the water pipes or in the pump,
or if flow is restricted in the hoses by some sort of blockage.
There could be an air leak in the hoses or pipes from the pool
or trapped air in the system.
The Turbo will attempt to clear it automatically several times
by surging the pump to dislodge air. If after several attempts it
cannot correct the lack of water flow, it will shut the machine
down and warn you that action must be taken to correct the
problem.
Running the iCool with no water flow can cause serious
damage because the heat exchangers will quickly freeze and
risk cracking the internal tanks. Lack of water flow will also
seriously damage the pump as there would be no lubrication
or cooling from water which is why the system will not allow it.
Water Flow Issue Fixed
if your Turbo can correct the lack of water flow itself it will do
so and advise it on the screen with a Green Tick Notification.
No action is needed, it will continue to operate correctly.
