Water Flow Issues
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.
Intelligent Water Flow
Correction
if the water does not flow steadily when you first start up due
to air being trapped in the pipes 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 by some sort of blockage (it could be
hair, dust or any other debris).

The machine 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 exchange will quickly freeze and
risk cracking the internal tank. 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 machine 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.
