PLACEMENT CONSIDERATIONS
Minimum Allowable Clearance and Service Access Requirements
Proper clearance for the outdoor unit coil is critical for proper operation. When installing the outdoor unit, consider service, inlet and outlet,
and minimum allowable space requirements as illustrated in the diagrams below.
• Include enough space for airflow and for service access. If installing multiple outdoor units,
of one unit will blow into the inlet side of an adjacent unit.
• If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that the discharge air of the outdoor unit isn't restricted.
• No obstacles to air circulation around the unit; keep proper distances from ceilings, fences, floor, walls, etc. (Install a fence to prevent
pests from damaging the unit or unauthorized individuals from accessing it.)
Mega and Mega 115V Outdoor Unit Service Access and Allowable Clearances
Specific clearance requirements in the diagram below are for all Mega outdoor units. The figure below shows the overall minimum clearances
that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other "roof-like structure", observe the clearance requirements (as
shown in Cases 1 and 2) for height in relation to the unit. To have successful service access to the outdoor unit, see figure below for mini-
mum spacing. When installing multiple outdoor units, see Cases 4 and 5 for correct spacing requirements.
If the outdoor unit is installed between standard and minimum clearances, capacity decreases approximately 10%.
