bypass defrosting mode will operate for 15 minutes or until the
evaporator temperature reaches 5°C.
Protection Systems
The heat pump has protection systems that will stop the operation of the
unit if:
Suction pressure drops due to refrigerant charge loss or air ow blockage
Over pressure (551 Psi) or over temperature (110°C) in the refrigerant
system
