WARNING

• BURST HAZARD
  Do not allow air or any gas mixture containing oxygen into refriger-ant cycle (i.e. piping)

• WARNING
  This symbol displayed on the unit indicates that this appliance is filled with R32, an odourless flammable refrigerant gas with low burning velocity (A2L class pursuant to ISO 817). If the refrigerant is leaked, there is a possibility of ignition if it enters in contact with an external ignition source.

• CAUTION
  This symbol displayed on the unit indicates that this appliance shall be handled by authorized service personnel only, referring to the  Installation Manual.

• CAUTION

This symbol displayed on the unit indicates that there is relevant information included in the Operation Manual and/or Installation  Manual.

• CAUTION

For more information, see the Installation and Operation Manual.

RISK OF EXPLOSION
The compressor must be stopped before removing the refrigerant pipes.
All service valves must be fully closed after pumping down operation.

• Make sure that unit installation and refrigerant piping installation comply with applicable legislation in each country. Also, in Europe, EN378 must be complied, as it is the applicable standard.
• The supplementary information about the purchased products is supplied in a CD-ROM, which can be found bundled with the outdoor unit. In case that the CD-ROM is missing or it is not readable, please contact your HITACHI dealer or distributor.
•  PLEASE READ MANUALS AND THE FILES ON THE CD-ROM CAREFULLY BEFORE STARTING WORK ON THE INSTALLATION OF THE AIR CONDITIONING SYSTEM. Failure to observethe instructions for installation, use and operation described in this documentation may result in operating failure including potentially serious faults, or even the destruction of the air conditioning system.
• Verify, in accordance with the manuals which appear in the outdoor and indoor units, that all the information required for the correct installation of the system is included. If this is not the case, contact your distributor.

R32 Refrigerant circuit
The unit installation and refrigerant piping should comply with the relevant local and national regulations for the designed refrigerant.
Due to R32 refrigerant and depending on final refrigerant charge amount, a minimum floor area for installation must be considered.

• If total refrigerant charge amount <1.84kg, there are no additional minimum floor area requirements.
• If total refrigerant charge amount ≥1.84kg, there are additional minimum floor area requirements to be checked.

Minimum area requirements

In case of total refrigerant amount ≥1.84 kg, the unit should be installed, operated and stored in a room with a floor area larger than the minimum criteria. Use following graphic and table to determine these minimum criteria.

NOTE

• In case of not achieving the minimum floor area, contact with your dealer.
• For further information about refrigerant charge refer to the Outdoor
• Unit Installation Manual.

DANGER

• Check to ensure that the number of below is within 0.44kg/m3. Otherwise it may cause danger situation if the refrigerant in the outdoor unit leaks into the room where this indoor unit is installed.
• (Total refrigerant quantity per one outdoor unit) ≤0.44kg/m3
• (Volume of the room where this indoor unit is installed) For detail, refer to the Installation Manual for outdoor unit.
• Make sure that the refrigerant leakage test should be performed. The refrigerant (Fluorocarbon R410A) for this unit is incombustible, non-toxic and odorless. However if the refrigerant is leaked and is contacted with fire, toxic gas will generate. Also because the fluorocarbon is heavier than air, the floor surface will be filled with it, which could cause suffocation.
• Use the specified non-flammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle. Do not charge material other than R410A into the unit such as hydrocarbon refrigerants (propane or etc.), oxygen, flammable gases (acetylene, etc.) or poisonous gases when in-stalling, maintaining and moving. These flammables are extremely dangerous and may cause an explosion, a fire, and injury.
