When Selecting the 45MBAA 24K/30K/33K/36K
Indoor Unit
A single 24K/30K/33K/36K indoor unit must be connected to the
“A” circuit. If there are two 24K/30K/33K/36K indoor units, they
must be connected with A and B circuits.

selected as one of the indoor units to be connected to the
multi-zone outdoor unit, larger ports should be used with
ports that have a 1/2 inch suction pipe diameter.

following steps.
1. Mark the position of bracket holes based on the dimensions chart.
2. Pre-drill the holes for the expansion bolts.
3. Place a washer and nut on the end of each expansion bolt.
4. Thread expansion bolts through holes in the mounting brackets, put
mounting brackets in position, and hammer the expansion bolts into the
wall.
5. Ensure the mounting brackets are level.
6. Carefully lift unit and place its mounting feet on brackets.
7. Bolt the unit firmly to the brackets.
8. If allowed, install the unit with rubber gaskets to reduce vibrations and
noise.

times.
