3Unit Placement
3.1 Placement Considerations
Unit placement should take account of the following considerations:
Units should not be installed in the following locations:
yWhere exposure to direct radiation from a high-temperature heat source or to interference from a source of
electromagnetic radiation may occur.
yWhere dust or dirt may affect heat exchangers.
yWhere exposure to oil or to corrosive or harmful gases, such as acidic or alkaline gases, may occur.
yWhere exposure to salinity may occur, such as seaside locations.
yWhere highly flammable materials are present.
yWhere exposure to oily air may occur, such as a kitchen.
yWhere exposure to very high humidity may occur, such as a laundry.
Units should be installed in positions where:
yThe ceiling is horizontal and is able to bear the unit’s weight.
yThere are no obstructions that could impede the airflow into and out of the unit.
yThe airflow out of the unit can reach throughout the room.
yThere is sufficient space for access during installation, servicing and maintenance.
yThe refrigerant piping and drain piping can be easily connected to the refrigerant piping and drain piping
systems.
yShort-circuit ventilation (where outlet air returns quickly to a unit’s air inlet) will not occur.
