FAQ’s for Climma Chilled Water Systems

Q Is digital display on?

If there is no power to the digital display check the breaker to the AC unit and that there is power to the AC main electrical box. Also check that the Vega panel is properly plugged in to the electrical box

Q The unit has power, the digital display is on but it will not run?

Make sure you have selected the correct operational mode on the panel – cool or heat mode

Make sure there is sufficient pressure in the chilled water circuit and that the flow switch has not activated as this will stop the compressor from starting.

Q Check the sea water pump is running and the system is primed and circulating enough water?

Check the sea cocks are open and that the sea water filter is clean and there is no growth or restriction in the pipework.

Q Check the fresh water pump is running and the circuit has the correct pressure?

The fresh water circuit should be pressurised to a minimum 1 bar and maximum of 3. If the pressure is too low the system needs to be topped up

Note: it is very important to always make sure that the correct level of antifreeze is in the system to protect the chiller
