COOLING OPERATION

How it works:

In cooling mode, your alice indoor unit will absorb heat from the

room, then the alice outdoor unit will discharge the heat to the

outdoors. The alice cooling capacity decreases as the outdoor temperature

increases. This causes the alice to work harder and longer to hold the

selected room temperature.

Indoor Coil Freeze Protection:

Frost may form on the indoor coil during cooling operations when the

outdoor temperature below 50°F (10°C). Prolong operation may cause ice

to form on the indoor coil and block airow. If the alice indoor unit

microcomputer detects ice on the indoor coil it will stop the compressor to

defrost the coil and protect the unit.

HEATING OPERATION

How it works:

In heating mode, your alice outdoor unit will absorb heat from the

outdoor ambient, then the alice indoor unit will discharge the heat to

the room. The alice heating capacity decreases as the outdoor temperature

decreases.

During extreme cold outdoor temperatures, you may need an additional

heating source to supplement the alice heating output.

Defrost Function:

In heating mode, frost may form on the outdoor coil during humid and low

outdoor temperature conditions. Prolong operation may cause ice to form

on the outdoor coil and block airow. This will reduce the alice’s heating

capacity.

If the alice microcomputer detects ice on the outdoor coil, it will switch

automatically to defrost mode to melt the ice and clear the coil. During

defrost mode, heating will be discontinued and the alice indoor unit

will ash the Defrost indicator. The compressor will continue to run while

indoor and outdoor fans will stop. It is normal to see steam or vapor coming

from the outdoor unit during defrost mode. Defrost mode will terminate 12

minutes after initiation of defrost cycle or when the outdoor coil temperature

is 50°F (10°C) or greater.
