CAUTION

1.Fragile, handle very carefully.

2.A control board contains integrated circuits, which are susceptible to failure due to static discharge. It is especially important to touch the metal part of the unit when handling or replacing the board.

3.Do not touch the electronic devices on the board or the back of the board to prevent damage to the board.

4.Do not change wiring and connections. Do not misconnect K3, K4 and K5, because the same connector is used for the thermistor and float switch. K4 is not connected.

5.Always replace the whole board assembly if it goes bad.

6.Do not short out power supply to test for voltage.
