The following safety precautions must be taken when installing the unit.
Be aware that AHU-KIT has to be combined with DVM Plus 3 or 4 Series outdoor unit only.
SAFETY INFORMATION
Risk of death or serious personal injury.
Potential risk of personal injury or material
damage.
Use R410A refrigerant.
When using R410A, moisture or foreign substances may affect the capacity and reliability of the product.
Safety precautions must be taken when installing the refrigerant pipe.
R410A 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.)
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 .
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.
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 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.
