• Before installation, check the supporting structure to ensure that it has sufficient load-carrying
capacity to support the weight of the unit along with any optional equipment.
• Do NOT install the cooling coil cabinet before lifting the packaged blower/furnace system into
position. Lift the cooling coil cabinet separately. Do NOT install the cooling coil cabinet while
the furnace is in operation.
The cooling coil cabinet is designed to enclose a field-supplied chilled water cooling coil and is shipped separately

(option AQ5). Option AU12 is a cooling coil cabinet with a downturn plenum with dampers (option AQ8).
