2. Too small space for the indoor unit will baffle the airflow, shorten the cooling cycle; the air supply and air
exhaust may mix, and the decibel may rise.
3. Do not place the indoor unit in a concave or at the end of a strip area.
4. Do not huddle multiple indoor units, lest there should be mixed airflow, unbalanced load and competitive
operation.
5. For the convenience of daily maintenance, do not install other equipment (such as smoke detector) above
the cabinet.
6. Backward fan downflow unit: because the fan needs to sink during the operation, so the floor must be
higher than 400mm.
Figure 2-17 shows the installation place of the indoor unit.
Maintenance space requirement
Leave more than 600mm of maintenance space in the front and on both sides of the chilled water AC unit, as
shown in Figure 2-17.
