NOTES:

* When the unit is operated above or below these limits for a long time, system diagnostics may detect

a malfunction and the unit will not operate properly.

** During heat pump operation the system will undergo several defrost cycles to remove ice that might

collect on the outdoor unit in very low ambient temperature.

After completion of defrosts cycle, the system will normally operate.
