On my control pannel is blinking AL2, what does it mean?
AL2 alarm indicates that the UV-C bulb is exhausted and it\\\'s therefore neccessary to replace it.
a) switch off the chiller pushing the on/off button and disconnect the supply cable
b) close the taps of water inlet and outlet and unscrew the ring nuts as well as the fairing ring nuts
c) pull out the air filter and pull the bottom of the fairing from the frontal part in order to separate it from the base NOTE: in the models TR-TC5 unscrew the two screws on the basement to remove the fairing
d) pull out the UV-C bulb from its location inside the exchanger and disconnect it
e) without touching the glass of the new UV-C bulb connect it to the joint and put it inside the exchanger restoring the rubber stopper in its position inside the ring nut for waterproof
f) close the fairing and restore the electrical and water connections
g) switch on the chiller and hold down the UV-C button for 10 seconds to reset the timer
