In the unlikely event that your system shuts itself down for any reason, you must identify and correct 

the problem that has caused the safety system to operate before allowing anyone to use the iCool. 

Never restart without identifying and correcting any fault.  

Operating Issues

Compact Not Cooling or 

Heating

Your iCool has several safety systems including one that 

prevents the gas pressure reaching a dangerous high level. 

This can only happen if the machine is extremely overheated.

If the machine has been operated in very hot conditions, in 

a confined space or if the airflow has been blocked or partly 

blocked for a certain amount of time, or if it’s placed too close 

to a wall, towel, source of heat or other object, it may cause 

the safety system to operate.

Damage resulting  by any of those reasons will not be 

covered under warranty. 

Cold only models: If your chiller is running normally but hasn’t 

changed temperatures after more than 45 minutes, please 

make sure that the Target Temp is lower than the actual 

pool temp. Cold only models do not have a heating capacity 

therefore the temperature of the pool must be higher than the 

pre-selected temperature. 

If your Compact is not cooling or heating at all but seems to be 

running correctly, it may most likely be out of refrigeration gas 

and needs to be re-gassed. Re-gassing can be done by your 

local refrigeration technician. 

Once re-gassed, you must absolutely provide enough 

ventilation to keep the machine within a safe operating 

temperature.

“System Too Hot” Warning

Your Compact can move large amounts of heat per hour. 

Naturally this heat has to be removed into the air surrounding 

the system. The powerful fan can normally handle this with 

ease, however if the air flow around the iCool is restricted so 

that the heat can not escape, or the outside air temperature is 

more than 45ºC, eventually the system will reach the limit of 

it’s safe operating range. If the temperature inside the cabinet 

reaches 70ºC the safety system will shut it down, sound an 

alarm and display the warning screen. 

Please make sure that the fan is turning on and the condenser 

fins on the Compact are not covered or restricted and that the 

area has a good flow of fresh air. On very hot days when the air 

temperature is more than 45ºC it may not be possible to run 

the system at full power due to the excessive heat.

Cooling a pool that has previously been heated can also cause 

a heat overload warning and shut down. This will only occur 

if the pool is still above 30-35ºC. It is good practice to allow 

the heat to reduce naturally to below 30ºC before starting the 

cooling cycle. This also saves a lot of electricity.

Software Not Loading

If the software doesn’t load for any reason, we recommend 

turning the unit OFF and ON first to see if that solves the issue. 

If the issue persists, please contact iCool Support.

Screen Freeze

This is a very rare issue.  If the screen freezes while the iCool 

is running normally, the main computer will usually still carry 

on running the system and monitoring the safety features 

but you will not be able to change anything and the displayed 

temperatures will not update. You can either allow it to keep 

running if that is more convenient, or you can restore the 

system to normal operation by switching off the main power 

and re starting again.

Remote Screen Not Connecting

If you’re operating via the optional 13” Remote Touch screen 

and the screen does not connect to your chiller, make sure 

that the data cable is correctly plugged to the chiller and to 

the back of the screen. You can also try turning the unit OFF 

and ON again and waiting for 30 seconds. The connection 

should be automatic.

Wifi Issues

If you’re unable to operate your chiller via Wifi, this is most 

likely due to a slow local Network or issues with your modem. 

In that case, you will need to operate your chiller from its in-

built screen. 

Water Leaks 

Please note that your unit is a very powerful chiller and 

condensation will occur inside of it. Water may leak at the 

back of the chiller, this is completely normal. If necessary, you 

can place a dripping tray under the unit to catch the overflow 

water.  

If leaks appear around fittings, unscrew fitting and add 

Plumbing tape to help seal the connector - this is widely 

available at any hardware store. 

Safety Switch Tripping

If your unit is tripping the safety switch, please make sure you 

are plugging the chiller to the same voltage noted on the side 

of the chiller. 

If that is correct, please check at what stage of the Progress 

Bar the unit trips. 

1

  If the chiller trips when the pump starts 

--> Check pump connection

2

 If the chiller trips when the compressor motor starts 

--> Please contact iCool Support

3

 If the chiller trips when the fan starts  

-->  Please contact iCool Support
