3Unit Placement

3.1 Placement Considerations

Unit placement should take account of the following considerations:

Units should not be installed in the following locations:

Where exposure to direct radiation from a high-temperature heat source or to interference from a source of

electromagnetic radiation may occur.

Where dust or dirt may affect heat exchangers.

Where exposure to oil or to corrosive or harmful gases, such as acidic or alkaline gases, may occur.

Where exposure to salinity may occur, such as seaside locations.

Where highly flammable materials are present.

Where exposure to oily air may occur, such as a kitchen.

Where exposure to very high humidity may occur, such as a laundry.

Units should be installed in positions where:

The ceiling is horizontal and is able to bear the unit’s weight.

There are no obstructions that could impede the airflow into and out of the unit.

The airflow out of the unit can reach throughout the room.

There is sufficient space for access during installation, servicing and maintenance.

The refrigerant piping and drain piping can be easily connected to the refrigerant piping and drain piping

systems.

Short-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.
