Handling and Placement of Condensing Unit
To minimize damage to the unit housing, it is recommended that the crate not be removed until the unit is moved to its final location.
The following should be considered when placing the unit:
A.The condenser coil (air inlet) should not be located so as to restrict air flow into the coil or direct facing of sunlight. A minimum of 12” is required (18” is preferred) between the face of the coil and a wall or other vertical obstruction.
B.Keep snow accumulation 18” to 30” away from condenser coils (air inlets) at all times.
C.A minimum of 30” is required on the three louvered sides to allow access for maintenance.
D.Do not position multiple units so that the air discharge of one is into the air intake condenser of another.
E.The roof mounting curb for the MAC units should be designed in such a way as to fully support all four of the bottom rails.
Holes are provided in the base supports for mounting bolts and for bridle lift rods.
