NOTES:
* When the system is operated above or below these limits for a long time, system
diagnostics may detect a malfunction and the system will not operate properly.
** During heat pump operation, the system will undergo several defrost cycles to eliminate ice
that might possibly collect on the outdoor unit in very low ambient temperatures.
After completion of defrost cycle, the system will normally operate
