4.2.4 Power supply check mode (OVD checking)

In this mode, an abnormal power supply can be checked Use this mode, when one or more of the following symptom occur

Symptom:

• It takes an excessively long time to boil water (The indicators on the operation panel are normal.)

• The pot/pan intermittently stops heating up (The indicators on the operation panel are normal.)

• The indicators on the operation panel disappear momentarily, or display intermittently (Heating power starts/stops neously with the blinking indicators.)

• Ascertain the source of the power supply noise and remove it (Refer to "Noise Incidents" - KAD0507001BE.)

1 Check if the electrical noise is being caused by other equipment in the house.

2 If the noise is a coming from an outside source, approach your power company for assistance.

5 Disassembly and Assembly Instructions

Important

• Be sure to turn off the circuit breaker before disassembling the IH cooktop.

• For assembly, refer to the tips provided and bear in mind that assembly is done in the reverse order of the disassembly dure.

1 Remove the main IH cooktop unit from the cabinet

(Built-in type).

• If the top plate has been bonded to the counter with

seal-ant tape (Sealing tape A), remove the tape with a plastic

spatula, taking care not to damage the counter.

2 Disconnect the power to the IH cooktop by removing the

plug from the electrical outlet.
