9.13.7. Installation (Oxygen) Check Control

••For operation check at installation and breakdown self- diagnosis, continuous operation of 2-way valve and vacuum pump is conducted by checking installation from indoor room.

9.14. Deice Control <Heating>

••Degree of frosting is expected by operation time, heat exchanger temperature and outdoor air temperature.

••According to frosting conditions, deicing operation is effectively performed.

1.Timer for deice control will function when outdoor heat exchanger temperature after continuous 40 minutes heating operation is below the primary judgment temperature. When the timer reaches 20 minutes or heat exchanger temperature is below the secondary judgment temperature, deicing operation will start.

2.Four-way valve is switched and deicing is performed by cooling cycle.

3.Deicing will be stopped when 12 minutes elapsed from starting of the operation or heat exchanger temperature reaches 17°C or more.
