Safety Information
When installing the product, the following safety precautions must be taken for the safety of an installer and user.
Use R-410A refrigerant.
f When using R-410A, the inow of moisture or foreign substances may greatly aect the capacity and reliability of the
product. Safety precautions must be taken when installing the refrigerant pipe.
f When charging mixed refrigerant, you should use liquid refrigerant (If you charge gaseous refrigerant, it may aect
the capacity and reliability of the product as a result of change in formation of the refrigerant.)
FOR INSTALLATION
WARNING
Disconnect all the power supplies before installation, service, and cleaning.
The installation must be done by the manufacturer or a qualied person.
f Installation by an unqualied person may result in a water leakage, electric shock or re.
Install the unit correctly according to the installation manual.
f An incorrect installation may result in a water leakage, electric shock or re.
Manufacturer of AHU KIT is not responsible for accidents due to incorrect installation by an unqualied person. Also,
you should use only supplied or designated parts and tools for installation.
f If you don’t use the designated parts and tools, product fall, water leakage, electric shock, or re may occur.
When adding refrigerant, use the R-410A refrigerant only.
f Using other types of refrigerant may result in product malfunction, explosion etc.
Do not use the pipe for R-22 refrigerant or are parts.
When there is refrigerant leakage during installation, you must ventilate the area.
f Toxic gas may be generated when refrigerant gas contacts with re.
If the power cable or cord is damaged, it should be replaced by manufacturer or qualied person. The electric work
must be done by a certied person according to code and standard about electric installation, regulation for indoor
wiring and installation manual. In addition, the electric work must be in compliance with rated electric specication.
f Voltage drop, shortage of supply voltage, incorrect power supply work and use of uncertied cables may result in electric
shock or re.
Arrange the cables between the AHU-KIT and outdoor unit so that the cover of electric part does not rise and then x
the cover of the electric box to the product rmly.
f If the cover is attached incompletely, a heat generation, electric shock or re of the terminal may occur.
The Power supply to the kit should be through dedicated MCCB/ELB or ELCB.
f If dedicated MCCB/ELB or ELCB is not provided, electric shock or re may occur because of overcurrent or leakage current.
Install the supplied cables rmly. Fix them securely so that external force is not applied to the terminal.
f If the connection or xing is incomplete, heat generation, spark and re may occur.
Make sure that the power for AHU-KIT is under maximum, and over minimum voltage.
f Failure to do so may result in product malfunction due to electrical component damage and functional degradation of a
part.
Use rated copper wire for the power cable.
Make sure electric wiring is correctly connected.
f Failure to do so may result in re with overheating.
Make sure there is no leakage of refrigerant gas after nishing installation.
f When leakage of refrigerant gas contacts with re, toxic gas may be generated.
