1. Precautions
When you start servicing, pay attention to the following points. For detailed precautions, refer to the
installation manual of the products.
CAUTION
• Service personnel
– Any person who is involved with working on or breaking into a refrigerant circuit should hold a
current valid certificate from an industry-accredited assessment authority, which authorizes
their 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 under
the supervision of the person competent in the use of flammable refrigerants.
– Servicing shall be performed only as recommended by the manufacturer.
• Work
– Work in confined spaces shall be avoided.
– The area around the workspace shall be sectioned off.
– Electric shock may occur. After turning off the power, always wait 5 minutes before touching
electrical components.
– Do not touch the fins of the heat exchanger. Touching the heat exchanger fins could result in
damage to the fins or personal injury such as skin rupture.
– Do not place any other electrical products or household belongings under the product.
– Condensation dripping from the product might get them wet, and may cause damage or mal-
function to the property.
• 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.
