WARNING:

Models with electric heaters: the unit is fitted with two thermostats - one with automatic reset and one with manual reset. If the manual thermostat also trips the

circuit, investigate and correct the cause. Switch OFF and ON the power supply to the electric heaters in order to reset the thermostat.

During heat pump operation the unit will undergo several defrost cycles to eliminate any ice that may have collected on the outdoor unit in very low ambient

temperatures. During these cycles, the indoor fan is automatically stopped and cannot be switched on until the defrost cycle is completed.
