Note: -

• There is no Service routine provided in this model.

• In Dlx models Diagnosis of the Error / Sensor / Pot failure is not of continuous nature. Service person

needs to restart the Product to listen to the Buzzer Beep for error indications if any.

• 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. 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.

•

In case of any Aluminum foil wrapping found over the Wiring harness either in FC compartment, RC

Compartment or in the Compressor deck area, the same Al foil should be carefully replaces in same

fashion after servicing

• In case of any detailed technical information please check with the Dlx technical specification.
