Notes:
1. Indoor temperature 27°C DB, 19°C WB; outdoor temperature 35°C DB; equivalent refrigerant piping length 7.5m with zero level difference.
2. Indoor temperature 20°C DB; outdoor temperature 7°C DB, 6°C WB; equivalent refrigerant piping length 7.5m with zero level difference.
3. Fan motor speed and air flow rate are from the highest speed to the lowest speed, total 7 rates for each model.
4. Sound pressure level is from highest level to lowest level, total 7 levels for each model. Sound pressure level is measured 1.4m below the unit in a
semi-anechoic chamber.
5. Unit body dimensions given are the largest external dimensions of the unit, including hanger attachments.

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.
