Safety Information
The following safety precautions must be taken when installing the unit.
Be aware that AHU-KIT has to be combined with DVM S Series outdoor unit only.
Use R-410A refrigerant.
•
When using R-410A, moisture or foreign substances may affect the capacity and reliability of the product.
Safety precautions must be taken when installing the refrigerant pipe.
•
R-410A is a quasi-azeotrope of two refrigerants. Make sure to charge liquid one when adding refrigerant.
(If you charge gaseous refrigerant, it may affect the capacity and reliability of the product as a result of change in
formation of the refrigerant.)
WARNING
•
Risk of death or serious personal injury.
CAUTION
•
Potential risk of personal injury or material damage.
CAUTION
•
Turn off the power before installation, service, and
cleaning.
•
The installation must be done by the manufacturer or
its service agent or a similar qualified person in order to
avoid a hazard.
–
Installation by an unqualified person may cause a
water leakage, electric shock or fire.
•
Install the outdoor unit correctly according to the
installation manual.
–
An incorrect installation may cause a water
leakage, electric shock or fire and so on.
•
Manufacturer is not responsible for accidents due to
incorrect installation by unqualified person.
•
Use only rated parts and tools.
–
If you don't use the rated parts and tools, it can
cause trouble with the product and bring about
injury.
•
When adding the refrigerant, use the R410A refrigerant
only.
–
If any gas or impurities except R410A refrigerant
come into the refrigerant pipe, serious problem
may occur and it may cause injury.
•
Use the pipe or flare part for R410A refrigerant only.
•
When there were leakage during installation, you must
ventilate the area.
–
Toxic gas may generate when refrigerant gas
contacts with fire.
•
If the power cable or cord is damaged, the
manufacturer, a qualified service technician must
replace it to avoid a potential risk.
•
The electric work must be done by service agent or
similarly qualified persons according to national wiring
regulations and use only rated cable.
–
If the capacity of the power cable is insufficient or
electric work is not properly completed, electric
shock or fire may occur.
•
Arrange the cables between the AHU-KIT and outdoor
unit after connecting.
Attach the cover securely so that the electrical
component box cover does not get loosen.
–
If the cover is attached incompletely, it can cause
trouble with a heat generation, electric shock or fire
of the terminal board.
•
Install designated ELB for AHU when installing the
power cable.
–
If you do not install designated ELB for AHU,
electric shock or fire may occur.
•
Install the cables with supplied cables firmly. Fix them
securely so that external force is not exerted to the
terminal board.
–
If the connection or fixing is incomplete, it can
cause trouble with a heat generation, electric shock
or fire.
•
Make sure that the power for AHU-KIT is under
maximum, and over minimum voltage allowed.
–
It may cause electrical component malfunction
which can damage the product.
•
Use the copper wire for the power cable and use only
rated cables and parts.
•
Make sure electrical circuit is correctly connected.
–
Overheating may cause fire.
•
Make sure there is no leakage after installation.
–
Toxic gas may generate when refrigerant gas
contacts with fire.
