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.

Caution
All installation, servicing and maintenance must be carried out by competent and suitably qualified, certified and
accredited professionals and in accordance with all applicable legislation.
Units should be grounded in accordance with all applicable legislation. Metal and other conductive components
should be insulated in accordance with all applicable legislation.
Power supply wiring should be securely fastened at the power supply terminals – loose power supply wiring
would represent a fire risk.
After installation, servicing or maintenance, the electric control box cover should be closed. Failing to close the
electric control box cover risks fire or electric shock.
Switch ENC1 (indoor unit capacity setting) is factory-set and its setting should normally not be changed. The only
circumstances in which a switch ENC1 might need to be set in the field is when replacing a main PCB. When
replacing a main PCB, ensure that the capacity setting on switch ENC1 on the new PCB is consistent with the unit
capacity given on the unit’s nameplate.
