NOTES:• Specifications are based on the following conditions:

– Cooling: Indoor temperature of 27 °CDB/19 °CWB, and outdoor temperature of 35 °CDB/24 °CWB.– Heating: Indoor temperature of 20 °CDB/15 °CWB, and outdoor temperature of 7 °CDB/6 °CWB.– Pipe length: 5.0 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)

• Protective function might work when using it outside the operation range.• *1: Maximum operating current is the total current of the indoor unit and the outdoor unit.• *2: Sound pressure level:

– Measured values in manufacturer’s anechoic chamber.– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.

• *3: Available on Google Play™ store or on App Store®. Optional WLAN adapter is also required. For details, refer to the setting manual.

• In 3-way outlet mode, changing of ceiling height setting by function setting 20 is prohibited. (Ceil-ing height setting [function setting 20] is allowed to be changed only in 4-way outlet mode.)

• Use the Insulation kit for high humidity (option), when the condition under the roof is over 80% inhumidity and over 30°C in temperature. Otherwise, there is a risk of condensation on the ceiling.

1. PrecautionsWhen you start servicing, pay attention to the following points. For detailed precautions, refer to theinstallation manual of the products.

CAUTION• Service personnel

– Any person who is involved with working on or breaking into a refrigerant circuit should hold acurrent valid certificate from an industry-accredited assessment authority, which authorizestheir competence to handle refrigerants safely in accordance with an industry recognized as-sessment specification.

– Servicing shall only be performed as recommended by the equipment manufacturer. Mainte-nance and repair requiring the assistance of other skilled personnel shall be carried out underthe supervision of the person competent in the use of flammable refrigerants.

– Servicing shall be performed only as recommended by the manufacturer.• Work

– Prior to beginning work on systems containing flammable refrigerants, safety checks are nec-essary to ensure that the risk of ignition is minimized. When repairing the refrigerant system,refer to the precautions written in the installation manual of the products before you start ser-vicing.

– Work shall be undertaken under a controlled procedure so as to minimize the risk of aflammable gas or vapor being present while the work is being performed.

– All maintenance staff and others working in the local area shall be instructed on the nature ofwork being carried out.

– Work in confined spaces shall be avoided.– The area around the workspace shall be sectioned off.– Ensure that the conditions within the area have been made safe by control of flammable ma-

terial.• Checking for presence of refrigerant

– The area shall be checked with an appropriate refrigerant detector prior to and during work, toensure the technician is aware of potentially flammable atmospheres.

– Ensure that the leak detection equipment being used is suitable for use with flammable refrig-erants, i.e. non-sparking, adequately sealed or intrinsically safe.

• Service parts information and design are subject to change without notice for product improve-ment.

• For the latest information of the service parts, refer to our Service Portal.https://fujitsu-general.force.com/portal/

• Precise figure of the service parts listed in this manual may differ from the actual service parts.
