User Manual Honeywell HF10CESWK Smart Wifi Portable Air Conditioner

Portable ACs use either a single hose or dual hose design.
In cooling mode, single hose PACs remove hot air from the
room, and then expel the hot air out the one hose. In
cooling mode, dual hose PACs bring in air from outside
through one hose, and expels warm air outside through the
second hose. In both cases cold air in cooling mode flows
through the unit's vents into the room.

The screen may not interfere with installation, but for better
releasing of hot air out the window, it is better to remove the
screen.

Casement windows are quite unique in design and
functionality so PACs do not have window kits that can
completely cover the gap for these types of specialty
windows.
