Daikin FBQ45EAVAK [4/60] Special notice of product

English3

• Do not install the air conditioner in the following locations:

1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).

Plastic parts will deteriorate, parts may fall off and water leakage could result.

2. Where corrosive gas, such as sulphurous acid gas, is produced. Also areas that are rich in sodium

such as seashores.

Corroding of copper pipes or soldered parts may result in refrigerant leakage.

3. Near machinery emitting electromagnetic radiation.

Electromagnetic radiation may disturb the operation of the control system and result in a malfunction

of the unit.

4. Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in the air,

or where v

olatile flammables such as paint thinner or gasoline are handled.

Operating the unit in such conditions may result in fire.

SPECIAL NOTICE OF PRODUCT

• Refrigerant

• The refrigerant R410A requires that strict Precautions be observed for keeping the system clean,

dry and tightly sealed.

A. Clean and Dry

Strict measure must be taken to keep impurities (including SUNISO oil and other mineral oils

as well as moisture) out of the system.

B. Tightly sealed

R410A contains no chlorine, does not destroy the ozone layer and so does not reduce the earth’s

protcetion against harmful ultraviolet radiation. R410A will contribute only slightly to the greenhouse

effect if released into the almosphere

• Since design pressure is 4.0 MPa or 40 bar (for R407C units: 3.3MPa or 33bar), the thickness of

pipes must be greater than previously. Since R410A is a mixed refrigerant, the required additional

refrigerant must be charged in its liquid state. (If the system is charged with refrigerant in its gaseous

state, due to composition change, the system will not function normally). The indoor units is designed

for R410A use.

See the catalogue for indoor unit models that can be connected. (Normal operation is not possible

when connecting units that are originally designed for other refrigerants)
