Product Usage Instructions
Before using the Utopia R32 Series, it is important to read the installation and operation manual carefully. The manual provides details on how to install and operate the product safely and efficiently. Here are some key usage instructions:
- Installation: The air conditioner must be installed by a professional installer according to applicable regulations. Contact the corresponding authorities for more information.
- Operation: Before turning on the air conditioner, ensure that all windows and doors are closed. This will help to maintain the temperature inside the room.
- Maintenance: Regular maintenance of the air conditioner is recommended to ensure optimal performance. Clean the air filters periodically to ensure that they are not clogged with dust and debris.
- Disposal: When disposing of the air conditioner at the end of its life, it must not be mixed with general house waste. It should be retired according to the appropriated local or national regulations in an environmentally correct way. Due to the refrigerant, oil, and other components contained in the air conditioner, its dismantling must be done by a professional installer according to the applicable regulations. Contact the corresponding authorities for more information.
Following these usage instructions will help to ensure the safe and efficient operation of the Utopia R32 Series air conditioner. If you have any questions or concerns, refer to the installation and operation manual or contact the manufacturer for assistance.

WARNING
BURST HAZARD
Do not allow air or any gas mixture containing oxygen into refriger-ant cycle
(i.e. piping)
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 refrig-erant 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.
- 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.
NOTE
In case of not achieving the minimum floor area, contact with your dealer.
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.
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 R32 into the atmosphere: R32 are fluorinated greenhouse gases
covered by the Kyoto protocol global warming potential (GWP) R32 = 675.
Do not vent R410A into the atmosphere: R410A are fluorinated greenhouse
gases covered by the Kyoto protocol global warming potential (GWP) R410A =
2088. Tn of CO2 equivalent of fluorinated greenhouse gases contained is
calculated by indicated GWP * Total Charge (in kg) indicated in the product
label and divided by 1000.
MODELS CODIFICATION
Important note: Please, check, according to the model name, which is your air conditioner type, how it is abbreviated and referred to in this instruction manual. This Installation and Operation Manual is only related to Indoor Units combined with Outdoor Units RAS-(4-6)H(V)R(C/P)2E / RAS-(4-6)H(V)N(C/P)2E.
