• To check whether Heater is working fine or not, service person can use the Power up initialization
function of the model, where Product need to be switched Off & need to be ensured that the temp at
the FC sensor is >0°c, then after making the product ON product goes into the Power up initialization
mode where after product switch ON, heater gets activated for the first 5 seconds & then it goes to the
compressor mode after 3 minutes of heater getting off. Service person can make the use of this 5
seconds where by putting the Tong tester one can easily identify the healthy/faulty condition of the
heater through the driving current displayed on the tong tester it self at the Electronic core board box
location without opening the FC Plenum.
