1.1.1 Norms and Regulations
Following Regulation EU No. 517/2014 on Certain Fluorinated
Greenhouse gases, it is mandatory to fill in the label attached
to the unit with the total amount of refrigerant charged on the
installation.
Do not vent R410A into the atmosphere: R410A are fluorinated
greenhouse gases covered by the Kyoto protocol global
warming potential (GWP) R410A = 2088.
2 SAFETY

2.1 APPLIED SYMBOLS

During normal air conditioning system design work or unit
installation, greater attention must be paid in certain situations
requiring particular care in order to avoid injuries and damage
to the unit, the installation, the building or to those in the
surrounding area. These situations will be clearly indicated in
this manual.
Signal words (NOTE, DANGER and CAUTION) are used to
identify levels of hazard seriousness. Definitions for identifying
hazard levels are provided below with their respective signal
words. Pay close attention to these symbols and to the
messages following them, as your safety and that of others
depends on it.

9 PMML0532 rev.1 - 12/2020
Tn of CO equivalent of fluorinated greenhouse gases contained
2
is calculated by indicated GWP multiply by Total Charge (in kg)
indicated in the product label and divided by 1000.
Appropriate refrigerant
The refrigerant used in each unit is identified on the specification
label and manuals of the unit. Hitachi shall not be held liable
for any failure, trouble, malfunction or accident caused by units
illegally charged with refrigerants other than the specified one.
Consequences of charging non-specified refrigerant
It may cause mechanical failure, malfunction and other
accidents. It may cause operational failure of protection and
safety devices of air conditioners. It may also cause lubrication
failure of the sliding part of the compressor due to deterioration
of refrigerant oil.
In particular, hydrocarbon refrigerants (such as propane,
R441A, R443A, GF-08, etc) are not allowed, since these are
combustible and may cause major accidents such as fire and
explosion in case of improper handling.
Once a non-specified refrigerant has been charged, no further
servicing (including draining of refrigerant) shall be performed,
even in case of malfunction. Improper handling of refrigerant
may be a cause of fire and explosion, and servicing in such
cases may be considered an illegal act.
End clients and costumers shall be informed that servicing is
not approved, and the installer who charged the nonspecified
refrigerant shall be asked to fix the unit.
Hitachi will accept no responsibility for units that have been
charged with non-specified refrigerant once.
