Cautions for using R32/R290 refrigerant
1. Installation (Space)
- That the installation of pipe-work shall be kept to a minimum.
- That pipe-work shall be protected from physical damage.
- That compliance with national gas regulations shall be observed.
- That mechanical connections shall be accessible for maintenance purposes.
- In cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction.
- When disposing of the product is used, be based on national regulations, properly processed.
2. Servicing
- Any person who is involved with working on or breaking into a refrigerant circuit should hold a
current valid certificate from an industry-accredited assessment authority, which authorises their
competence to handle refrigerants safely in accordance with an industry recognised assessment
specification.
- Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance
and repair requiring the assistance of other skilled personnel shall be carried out under the super-
vision of the person competent in the use of flammable refrigerants.
3. Do not use means to accelerate the defrosting process or to clean, other than those recommended
by the manufacturer.
4. The appliance shall be stored in a room without continuously operating ignition sources (for example:
open flames,an operating gas appliance or an operating electric heater).
5. Do not pierce or burn.
6. Be aware that refrigerants may not contain an odour.
7. Be more careful that foreign matter(oil, water,etc) does not enter the piping. Also, when storing the
piping, securely seal the opening by pinching, taping, etc. For indoor units, use R32 flareless joint
assy only when connecting the indoor unit and connecting piping(when connecting indoors). Use of
pipes, flareless nut or flare nuts other than specified, may cause product malfunction, burst piping,
or injury due to high internal pressure of the refrigerant cycle caused by any inflow air.
WARNING
Appliance shall be stored in a well -ventilated area where the room size corresponds to the room area as
specifiec for operation.
For R32 frigerant models:
Appliance shall be installed, operated and stored in a room with a floor area larger than 4m².
Appliance shall not be installed in an unvertilated space, if that space is smaller than 4m².
For R290 refrigerant models, the minimum room size needed:
<=9000Btu/h units: 13m², >9000Btu/h and <=12000Btu/h units: 17m²
>12000Btu/h and <=18000Btu/h units: 24m²
>18000Btu/h and <=24000Btu/h units: 35m²
WARNING: Installation, servicing and decommmissioning shall only be performed as recom-
mended by the equipment manufacturer. Maintenance and repair requiring the assistance
of other skilled personnel shall be carried out under the supervision of the person compe-
tent in the use of flammable refrigerants. For more details, please refer to the section of
Caution: Risk of fire
"Information on servicing". (This is only required for the unit adopts R32/R290 refrigerant).
