4. 18-class unit in single operation

NOTE:The unit of pressure has been changed to MPa on the international system of units(SI unit system). The converted score against the traditional unit system can be gotten according to the formula below.

1(MPa • G) =10.2(kgf/f • G)

<How to work fixed-frequency operation>

1.Set emergency switch to COOL or HEAT.The switch is locat- ed on indoor unit.

2.Press emergency run ON/OFF button. 3.Compressor starts running at rated frequency. 4.Indoor fan runs at HI speed.

5.To cancel this operation,press emergency run ON/OFF button or any button on remote controller.
