Understanding Water flow Problems
The water flow warning screen will display if the water
flow does not begin or if it fails for any reason. Running
the iCool with no water flow can cause serious damage
because the heat exchanger tanks will quickly freeze.
Frozen water expands considerably and this can cause
damage to the tanks.
Lack of water flow can seriously
damage the pump
as there would be no lubrication or
cooling from the water.
If you are absolutely certain that the system is
stopping because of a false or overly sensitive
water flow alarm, there is a provision to over
ride the automatic shut down, but please
be
warned that o
nce you disarm the flow safety
monitor, nothing will stop the system even if water is not flowing
, Therefore this over ride function is only to be
used for short periods where it is essential to keep your system operating until the reason for the false alarm can
be determined and corrected.
Water Flow Can Also Stop If The Heat Exchanger Tanks are Frozen Solid.
If you set the temperature below about 7ºC or 45ºF it is occasionally possible in certain climatic conditions for the
heat exchange tank to freeze solid. This will block most or all of the flow of water. In order to cool the pool water to
these extremely low temperatures the system must cool to at least 5ºC below the set temperature and this takes it
very close to the temperature that water freezes solid. There is an anti freeze safety circuit, however it is sometimes
possible for the tanks to freeze in an area not covered by the protection sensors.
If the tanks freeze up, the system will stop to protect the tanks and the screen will sound an alarm and give advice.
Allow 30 minutes for the ice to melt and then set the temperature a little higher and restart. Normally settings above
8ºC or or 45ºF will not freeze the tanks in any conditions.
Safe Temperature Settings.
Following international safety reccomendations your iCool will not accept water temperature settings below 5ºC or
40ºF as this would put athletes using the system at risk of hypothermia.
The tanks can only freeze if your setting is below 7 to 8ºC and this can only happen in certain conditions. If your set
temperature is above this then it is much more likely that the system has stopped because of a lack of water flow
caused by either a pipe or filter obstruction, or an air leak in the hoses or pipes from the spa pool, or trapped air in
the system.
If there is a possibility that the heat exchanger tank is frozen, then you must allow the system to warm up for about
30 minutes to thaw the ice. Leave the power switched on so that the fans can operate if necessary to thaw out the
titanium tanks.
After thawing, set a new temperature no lower than 8 or 9ºC before restarting to prevent the tanks freezing again.
Automatic Operation of the Air Fans.
Your TurboCool is very powerful and is capable of removing up to 10,000 watts of heat from a pool per hour. To re-
move heat from the the 2 powerful heat pumps in the TurboCool it has 2 very high powered linear flow cooling fans
that cool the condensers compressors and other components. At full power these fans can move 2200 cubic feet of
air per minute. During normal operation the fans will automatically change speed as required to maintain safe tem-
peratures and high water cooling efficiency. The fans will be at full speed when temperatures are high or the water
is warm. To save electricity the fans will only operate at the exact flow required. Low speed always begins whenever
power is applied to the iCool while in the cooling mode. There are no run time limitations on the fans and they use
very little power at low speed. In the heating mode, medium speed is set and locked.
